90+ percent of the time, the sensors are killed by letting the gauge "warm up" the sensor before starting the engine. Nobody tells you ( except me ) that "warmed up" means GLOWING ORANGE HOT 1200F. AND that the sensor element, inside, is CERAMIC. So, turning the ignition on and letting it set there for a few seconds, before starting the engine causes the HOT ceramic element to get hit with a rush of cold exhaust ( and, usually some condensation water ). This causes fractures in the ceramic element. The cracks grow on every heat cycle, like windshield cracks. First, the sensor loses accuracy, because of air leaks. Then, eventually, the cracks hit something REALLY important. And, the sensor will just show FULL LEAN, 14.7, or FULL RICH. They usually start out being finicky about EGT.
@@awautoworks4426 Just follow the normal installation. The trick is to never leave the ignition on for more than a few seconds before starting the engine, As soon as the WB gets power, it starts heating the sensor. Original equipment ECU WBs know when the engine is running ( Because they are in the ECU ). So, they don't start heating up until after the engine is running. Aftermarket WBs, generally, don't know if the engine is running, or not, until it is too late. If you have left the gauge on, for more than a few seconds, without starting the engine, power it off, for at least 30 seconds, to let the sensor cool down to just scalding hot, before starting. If you see an AFR number, or " - - - -" , the sensor is, generally, already at full temp.
Turbo Grocery ...or you can wire in a switch so that you can turn it on yourself a short time after starting the engine. I turn mine one around 20 seconds later. This kind of mimics the stock ECU only activating the wideband after exhaust is warm. I wired mine through a relay, which is generally recommended, but put in a simple on/off toggle switch (or you could use a rocker switch).
AEM Fuel Ratio is the worst. I'm having the same problem in my 1970 Nova SS . AEM sent me a sensor but before they did I had to take a video of me cutting the harness as close to the sensor as possible. I installed the new sensor they sent and what else, the same problem. Now AEM wants me to take a video smashing the gauge before they send a new one. I told them I tested the gauge and it is working properly as per specs. It fails only when sensor is connected to it. It is doing exactly what the last sensor did to it. I asked for a new sensor and the guy said that it's not the sensor because we replaced it with a new one. I told him that just because it's new doesn't mean it is good. As an aircraft engineer with 40 years of experience I trust old parts that are proven to work correctly, then a new part. He told me that he is the expert on this AEM part and he is not supporting me. I told him to go jump in a lake and put the Guage kit on my wall with a note to all customers not to buy or trust anything made by AEM.
So I just had the same problem. I performed all the same checks as he did and my issue was the O2 SENSOR. I am willing to bet that the new sensor he got was also defective. The directions tell you which sensor to buy and I was able to get mine at autozone. Buy 3, return 2 once you get it working. ☺️
Just got another one for my other car. The original still works flawlessly. New one leans out whether car is running or not. Hooked the new sensor up to my old gauge and it leaned out almost instantly. The sensor is dead. Probably during shipping, because many delivery drivers drive like maniacs with packages flying everywhere and these bosch lsu 4.9 sensors are very very sensitive to being dropped.
Have had similar issued in the past, actually had a meeting with AEM and it is the sensors. They're releasing a new updated sensor here in the next few weeks
Literally same deal here! On my 3rd replacement and mine just pegs out lean or ---. Really annoyed at the fact that they as well didn't send a new sensor in my replacement kits.

Glowshift black series 7 is good not e85 supported though... Innovative or Apexi or Apex then... I have a x series and its good for me... Really sensitive on the numbers but its weird that your going through that... Just a thougt if you have a no cats run the ls9 sensor on the rear passenger o2 and delete it just the bk rear... Worked on my mustang but on subi not sure hate the bung weld crap and its just a thought if you haven't tried it... Good luck on that subi sounds good.. If you do the delete have the rear passenger o2 turned off or check light will be tossed on... Just clear the code or codes and turn just that one off.. Again maybe where the location of the ls9 is at? Hope it works....
I know this is a late response but my afr gauge isn’t even lighting up when i start my car. But once i press the right button on the gauge itself it’ll start reading “O2, afr” and something else i forgot, then when i press the left one it’ll read “donE” and shut back down I’m not sure what the problem is. But my boost gauge seems to be working fine
ok so swapping gauges and wires didnt work, did the actual sensor get swapped for a new one? after the montage it just jump cuts to him saying he will put some other old one or the same one in? did a new sensor go in?
I just installed mine and it reads 16.50-16.70 on idle😳 but on the accessport it reads normal afr about 14.70 but when I cruise normal driving the numbers seem to be a lot closer (about 14.9-15.2) on the aem and about 14.7 on the accessport do u know why my idle could be reading so lean?
Arnaldo Graceski you can calibrate it like you said or aem has pre tuned it from their factory ready to go its either way... They make it have a calibration test if you have issues with it or if its dirty and you re clean it and the gauge is not showing the numbers accurately etc...
Smeedia, I’ve been running E85 in my 2015 FRS for 5 yrs. delicious flex fuel tuned. Went from my sprintex supercharger 287/232 Trq back to N/ A to learn better car control at track events. My son surprised me with a current SBD turbo kit. I’m finishing up my supporting mod purchases before my install myself next month. I’m retired Air Force aircraft mechanic so I’m up to the task. I’m adding an oil temp gauge and of course boost gauge. Now I’m all screwed up in so much as adding a decent AFR gauge. I know I’m damn sure not going AEM. I’m asking you which gauge/ sender kit do you recommend now, which ones are compatible with E85. I damn sure don’t want to go through this headache 3 , 4 times. I was initially thinking pro sport gauges due to their electronic box as easy access. Need help here amigo. Thx in advance.
So I love the AME gauge itself but the sensors are trash. For me I used the AEM pig tail with a Bosch sensor I bought off of amazon and spliced the two together. Used it in my STI on E85 Nd had no issues with sensor failure. I use thr same Frankenstein of a sensor in my turbo BRZ and it handles the heat very well. If your using ECU Tek for your FRS you can monitor oil temp from the app on your phone as well. 🙏
As for proportion ive never been a huge fan of them, I like guages that stand out and are quick to reference when driving. But prosport has a good reputation, not too sure on what sensors they use though
Smeedia thx bud as always, I’m running the delicious flex fuel app for ethanol content and presure on my I phone. So that screws me up for having my phone tied up damn it. I wish I could find away to add an ethanol permanent gauge to the delicious flex fuel set up without the Bluetooth operation. Without having to but a complete different E85 kit. My problems ha ha I’m rambling. But thx sir
Smeedia I’m Ecutek tuned but not via the blue tooth I’ve got the old cable set up and update it every other month. I guess it’s time to update more money spent 😁
Bought the 30-4110 kit, so far two sensors are screwed up. Did you just keep getting new sensors until they worked or found another sensor part number that was good?
what the hell is wrong with AEM if this is a consistent problem..I just got one installed on my bike and its doing the same exact thing..Im going to write to company about getting a replacement sensor and take it from there.
So on my boosted GSR fully built Turbo E85 flex fuel I was having the same - - - - - issue but noticed whenever I Pressed and held the window up or window down button it would read correctly within range as soon as I let go of the button it would Go back to - - - - - I have not really troubleshooted yet since I have aem cd7 dash and can get accurate readings from the can bus it's using.....FWIW
I feel your pain, I have the same issues with a grams performance A/F gauge. I believe it might be a bad sensor, was working fine and now it just read lean, even when driving. Any updates on what caused it to do this on your end?
It was the sensor, I ended up buying a generic sensor off of amazon and using the Pig tail from AEMs sensor, spliced them together and its worked great ever since. I know the frustration though of getting one and it not working though 🙃
Ended up swapping to a Amazon O2 sensor. Even today AEMs sensors are still poop. Last time I talked with them they said they had a revised sensor in the works. IMO it's not worth sending the unit back. You'll get another sensor that will kill itself. And 5 pin Lamda 4.9 LSU Sensor off Amazon should work
I called them and told them I put new sensor in new gauge in still don’t work they were insisting that it’s the gauge and to send it back to them and by a new gauge and harness
so I have an issue with my wideband guage maybe you can help. It doesn't display all the digits. example 14.7 as 14 and a part of the digit. Any suggestions?
The problem is maybe the sensor location. I've got inovate AFR Gauge and the sensor right back after the turbo (Invidia Cat'ed downpipe). I've already replace 3 sensors. I install a switch to power the gauge and heat sink bung but i still have issues with the sensors. I was thinking of change for a AEM afr kit but i see you've got the same issues. (Sorry for my bad english i'm french)
I have used Inovate afr gauges on other cars without any issues but my sensors was more far from the turbo. What downpipe are you using? Are you still catted?
The STI was catted at the time of this video, had the exact same issue with a brand new gauge on my BRZ and the sensor was farther back. Ive heard of people installing switches to them with mixed results. And no worries at all!
When it stays 14.7 no matter what means the sensor isn't connecting btw. Innovate is cheaper and way better, it has error codes and you can actually cal
innovate is as big a POS as the AEM, I have an innovate and its been garbage out of the box, multiple sensors etc, still junk, STAY AWAY FROM INNOVATE! Look online there are pages of complaints, count yourself as one of the few lucky ones,
@@WolfHausMotorwerks you probably did something wrong or bought it from some kid named Eric... Just by looking at your channel you don't seem to be a tuner so you're experience in tuning probably isn't any good
Hahaha, this is funny.............I had an Innovate AFR gauge, it worked for 9 months. Warranty had run out so I just bought the AEM unit without a sensor knowing the sensors are the same for both. Guess I was wrong. Gauge goes to full lean when you turn it on, which means no sensor is connected. Different sensors......Edit... no no no, I just put a lighter to the sensor and it works. The problem I had was there was a bung extension and the sensor wasn't reading.
@@chuckheinch mine has done the same thing, worked perfect for like 10 min, then 3 dash, hondata says its pushing 3.9 volts entire time. weird thing about mine is that it starts at 14.7 while warming up im assuming then it actually ticks through all the numbers nearly to 3 dashes. my bung was the same the entire time so I dont think its the bung or it wouldnt have worked perfect for 10 min imo
My boost gauge is flat lined tried different fuses. The connections are good and it is sharing power to the afr gauge...idk about aem I really wanted to stick with aem since I want everything to be the same... pretty pissed haha
Hey man, I’m just curious if you’re her figured out the issue. I just installed same wideband and idled then drove for 10 minutes working normal then all sudden went to 3 dashes. Works for a few seconds on start up then goes back to the 3 dashes. I’m assuming o2 sensor bad?
They shoudlent go out in the first week of using them, have had multiple sensors from AEM do this, always replaced with $30 Amazon Bosch sensors that have worked for 2+ years
I'm having the same problem with mine. Two consecutive sensors lasted 10 seconds before the went bad. Same shit, 14.7 and then all dashes seconds after start up. Going with another company besides AEM. Their sensors are junk! When they still used Bosch Sensors they were great. Now its Chinese Junk DOA sensors.
The link to the gauge should be in the description, but it was the sensor, ended up having to buy one off of Amazon and splice the pigtail from AEM sensor onto it to get one working
My original Bosch sensor worked for about 8 months before it started reading incorrectly and not reading at all. I replaced it with an Amazon equivalent which worked for about 3 weeks but started doing the same as the old one then one day it repeated the heat cycle multiple times completely. My sensors about 24 inches from my turbo at about a 9 o'clock angle.
LMAO yo i dont mean to laugh but IM GOING THRU THE SAME SHIT, and.. my gauge did the sAME SHIT. like itll start at 14.6-7 and then BOOM - - - and then u rev it, itll go down like it works, and u let it idle, 18.2-3-4 and then - - - again lol. I cant lie tho my sensor is old, 2 years old. But i jus wanted to know what was the issue from u guys side and now ima jus buy a sensor.
@@Smeedia Why did you have to splice the wires? It looks like the sensor should plug right up - The Amazon add says it's supposed to fit the AEM. Each 4.9 sensor has a calibration resistor built into it's connector, so the connector that comes on the sensor not supposed to be eliminated. Just trying to understand where you spliced things??
I posted as Goldie to explain the setup I used if anyone does the o2 idea you will have to tune it everytime the engine light comes on with a tuner or just weld the bung 18"in from the cylinder head but, you might have pinched or kinked the harnesses that might be messing with it or a bad sensor then....
My issue ended up being the sensors that AEM kept sending me, eventually ended up just buying a sensor in Amazon and splicing the harness to the new sensor to make it work lol
Smeedia do you have a video or wiring diagram which color Aem sensor wire splices to the new sensor you got from Amazon have a replacement coming but not confident on the replacement either,thanks
Did you make a video splicing the sensor to the AEM gauge? I'm experiencing the same issues and want to try what you did but I can't seem to find a video. I just want to be able to splice the two together correctly! Thanks for any input!
You bought a knock off o2 sensor. Let me guess.....you bought it as a kit off Amazon or something. Pull your o2 sensor probably doesn't have Bosch or any markings on it. AEM didn't sell it as a kit thats why they didn't send you a new o2. These fools will provide a chinese o2 and claim its a bosch and it'll never read right. Buy the right bosch o2 for 120 bucks and stop all the silly business of checking grounds etc.
That's the sensor that came with the AEM wide band. Ans it is indeed from AEM with their provided sensor. Funny enough thr cheap Amazon sensor I replaced it with went 3 years strong.
Mine just goes from 14.7 then goes alllll the way to 18 then those three lines.... and does not move... been doing this for 2 days..... but idk maybe i’m running way too lean.
@@Smeedia Yeah just did more research but thanks for responding ive been freaking out 😂, would you think a ProSport Bosch wideband fit an AEM female connector?

Yessir, that's what I use. Been going strong for 2+ years
@@Smeedia do you have a link or the name of the sensor so that I can check it out?
I just cleaned my sensor… it worked for a bit &’ then stopped working. This is bunk af right in the middle of logging back and forth w my tuner
Glowshift black series 7 is good not e85 supported though... Innovative or Apexi or Apex then... I have a x series and its good for me... Really sensitive on the numbers but its weird that your going through that... Just a thougt if you have a no cats run the ls9 sensor on the rear passenger o2 and delete it just the bk rear... Worked on my mustang but on subi not sure hate the bung weld crap and its just a thought if you haven't tried it... Good luck on that subi sounds good.. If you do the delete have the rear passenger o2 turned off or check light will be tossed on... Just clear the code or codes and turn just that one off.. Again maybe where the location of the ls9 is at? Hope it works....
Wtf r u even talking about
Do you have a link to the Bosh sensor you are suggesting?

Thanks for the help this sensor also worked for me! 👊🏼
@@Smeedia Mine just died as well, just ordered this sensor.
I know this is a late response but my afr gauge isn’t even lighting up when i start my car. But once i press the right button on the gauge itself it’ll start reading “O2, afr” and something else i forgot, then when i press the left one it’ll read “donE” and shut back down
I’m not sure what the problem is.
But my boost gauge seems to be working fine
I’m having the same issue
Were you able to fix the problem?
Mine is doing same thing but it worked great for a week are these sensors just garbage or what
ok so swapping gauges and wires didnt work, did the actual sensor get swapped for a new one? after the montage it just jump cuts to him saying he will put some other old one or the same one in? did a new sensor go in?
I just installed mine and it reads 16.50-16.70 on idle😳 but on the accessport it reads normal afr about 14.70 but when I cruise normal driving the numbers seem to be a lot closer (about 14.9-15.2) on the aem and about 14.7 on the accessport do u know why my idle could be reading so lean?
Ots tune or protune?
Initial thought would be the sensor or sensor location
I thought that when using a new gauge you had to leave the sensor out, let it cycle, then install it
Arnaldo Graceski you can calibrate it like you said or aem has pre tuned it from their factory ready to go its either way... They make it have a calibration test if you have issues with it or if its dirty and you re clean it and the gauge is not showing the numbers accurately etc...

Smeedia, I’ve been running E85 in my 2015 FRS for 5 yrs. delicious flex fuel tuned. Went from my sprintex supercharger 287/232 Trq back to N/ A to learn better car control at track events. My son surprised me with a current SBD turbo kit. I’m finishing up my supporting mod purchases before my install myself next month. I’m retired Air Force aircraft mechanic so I’m up to the task. I’m adding an oil temp gauge and of course boost gauge. Now I’m all screwed up in so much as adding a decent AFR gauge. I know I’m damn sure not going AEM. I’m asking you which gauge/ sender kit do you recommend now, which ones are compatible with E85. I damn sure don’t want to go through this headache 3 , 4 times.
I was initially thinking pro sport gauges due to their electronic box as easy access. Need help here amigo. Thx in advance.
So I love the AME gauge itself but the sensors are trash. For me I used the AEM pig tail with a Bosch sensor I bought off of amazon and spliced the two together. Used it in my STI on E85 Nd had no issues with sensor failure. I use thr same Frankenstein of a sensor in my turbo BRZ and it handles the heat very well. If your using ECU Tek for your FRS you can monitor oil temp from the app on your phone as well. 🙏
As for proportion ive never been a huge fan of them, I like guages that stand out and are quick to reference when driving. But prosport has a good reputation, not too sure on what sensors they use though
Smeedia thx bud as always, I’m running the delicious flex fuel app for ethanol content and presure on my I phone. So that screws me up for having my phone tied up damn it. I wish I could find away to add an ethanol permanent gauge to the delicious flex fuel set up without the Bluetooth operation. Without having to but a complete different E85 kit. My problems ha ha I’m rambling. But thx sir
Smeedia I’m Ecutek tuned but not via the blue tooth I’ve got the old cable set up and update it every other month. I guess it’s time to update more money spent 😁
@@Smeedia what bosch sensor you get? I just ordered an aem gauge with a bosch sensor
Bought the 30-4110 kit, so far two sensors are screwed up. Did you just keep getting new sensors until they worked or found another sensor part number that was good?
I bought a buosh sensor off of amazon and spliced it to thr AEM Pig tail
Smeedia awesome, thanks for the reply! It’s so sad the kit cost so much bunch still requires a different o2 sensor.
www.amazon.com/dp/B07K1SMQYH/ref=cm_sw_r_cp_apa_i_ZbtsFbB96ZDSH
Thats the one I bought, and all I did was splice into the harness and solder on thr new pig tail from AEM 🙏
Bryan T it’s up to you and research stuff on your own, don’t blame him for free advice he gives on RUclips.
what the hell is wrong with AEM if this is a consistent problem..I just got one installed on my bike and its doing the same exact thing..Im going to write to company about getting a replacement sensor and take it from there.
You need to stop listening to me work.. telling the gauge "I hate you" ? LOL
So on my boosted GSR fully built Turbo E85 flex fuel I was having the same - - - - - issue but noticed whenever I Pressed and held the window up or window down button it would read correctly within range as soon as I let go of the button it would Go back to - - - - - I have not really troubleshooted yet since I have aem cd7 dash and can get accurate readings from the can bus it's using.....FWIW
I just picked up a 30-4110, the car is stuck on LEAN
Happened to me as well. Was a bad sensor
I feel your pain, I have the same issues with a grams performance A/F gauge. I believe it might be a bad sensor, was working fine and now it just read lean, even when driving. Any updates on what caused it to do this on your end?
It was the sensor, I ended up buying a generic sensor off of amazon and using the Pig tail from AEMs sensor, spliced them together and its worked great ever since. I know the frustration though of getting one and it not working though 🙃
Smeedia would you have a link for that sensor?

@@Smeedia Thanks
I’m going through this right now did you ever resolve this his problem or did you just get a hole new unit
Ended up swapping to a Amazon O2 sensor. Even today AEMs sensors are still poop. Last time I talked with them they said they had a revised sensor in the works. IMO it's not worth sending the unit back. You'll get another sensor that will kill itself.
And 5 pin Lamda 4.9 LSU Sensor off Amazon should work
I called them and told them I put new sensor in new gauge in still don’t work they were insisting that it’s the gauge and to send it back to them and by a new gauge and harness
so I have an issue with my wideband guage maybe you can help. It doesn't display all the digits. example 14.7 as 14 and a part of the digit. Any suggestions?
Which gauge did you get? 🙏
@@Smeedia Uego
Aem
I figured it out on mode keep Clicking till it says recal and click sel and then switch back to afr do it few times and Boom 💥💪🏻 Hope it helps u all
What if ours have no damn buttons on the gauge ? LMFAO
@@poohnay16then we’re fucked
Stupid question but what’s the point if the STI already have a boost gauge in the middle screen just curious
A direct feed or source is more accurate, the ECU doesn't have to decode data or information then said it to the OFD
😂I need to try the yelling tapping and flicking, mines doing the same exact thing.
It worked momentarily 😅😅😅
Newb question here. Why would you run a AFR gauge, doesnt the AP give you that information already?
The accessport reads upstream AFR off of the header compared to the downstream on the downpipe
@Smeedia I'm learning still but isn't it also becausethe aem uego is a wideband and the stock is narrow band?
Did you end up finding the issue? I have a brand new aem afr then was good then - - - :(
Bad AFR sensor out of the box 😭 ended up getting a replacement off of Amazon
@@Smeedia Forsure bro thank you 🙏🏻
I’m having the same exact problem with my AEM sensor I installed a couple weeks ago. Pegged out to lean
Bad sensor. Annoying problem but an easy fix
Did you try and run calibration settings
Why not just change the obvious thing first? THE SENSOR.
The problem is maybe the sensor location. I've got inovate AFR Gauge and the sensor right back after the turbo (Invidia Cat'ed downpipe). I've already replace 3 sensors. I install a switch to power the gauge and heat sink bung but i still have issues with the sensors. I was thinking of change for a AEM afr kit but i see you've got the same issues. (Sorry for my bad english i'm french)
I have used Inovate afr gauges on other cars without any issues but my sensors was more far from the turbo.
What downpipe are you using? Are you still catted?
The STI was catted at the time of this video, had the exact same issue with a brand new gauge on my BRZ and the sensor was farther back. Ive heard of people installing switches to them with mixed results. And no worries at all!
@@Smeedia Brz Catted also?
Catless on the BRZ
@@Smeedia the sensor you've used on the BRZ was a brand new sensor too?
Can bad fuel be the source too for not reading it? All I get is 3 dotted lines but my AP says otherwise.
9/10 times it's thr sensor bad fuel wouldent cause it to read 3 lines
When it stays 14.7 no matter what means the sensor isn't connecting btw. Innovate is cheaper and way better, it has error codes and you can actually cal
Good to know, AEMs customer support was pretty quick to fix the error but still had to go through 4 sensors lmao
@@Smeedia ouch, yeah I've had innovate for like 5 years and only had to change sensors, buy one from oriellys with a lifetime warranty lol
innovate is as big a POS as the AEM, I have an innovate and its been garbage out of the box, multiple sensors etc, still junk, STAY AWAY FROM INNOVATE! Look online there are pages of complaints, count yourself as one of the few lucky ones,
@@WolfHausMotorwerks you probably did something wrong or bought it from some kid named Eric... Just by looking at your channel you don't seem to be a tuner so you're experience in tuning probably isn't any good
When I had innovative afr I went through 2 o2 sensors so I just switched aem afr x-series. I hope it doesn't fail.
Hahaha, this is funny.............I had an Innovate AFR gauge, it worked for 9 months. Warranty had run out so I just bought the AEM unit without a sensor knowing the sensors are the same for both. Guess I was wrong. Gauge goes to full lean when you turn it on, which means no sensor is connected. Different sensors......Edit... no no no, I just put a lighter to the sensor and it works. The problem I had was there was a bung extension and the sensor wasn't reading.
Meaning the sensor wasn't deep enough? I may grind my bung down. I had to weld it
@@chuckheinch mine has done the same thing, worked perfect for like 10 min, then 3 dash, hondata says its pushing 3.9 volts entire time. weird thing about mine is that it starts at 14.7 while warming up im assuming then it actually ticks through all the numbers nearly to 3 dashes. my bung was the same the entire time so I dont think its the bung or it wouldnt have worked perfect for 10 min imo
@@pitbullhaven it was a bad 02 sensor. Had to pull it completely out and send it all back.
T was the sensor the entire time. Bosch sensors are junk
Is there any replacements for it besides Bosch?
My AFR reads 8.08 for roughly 15 minutes after initial start up, reads correctly for about 10 minutes then goes back to 8.08 😅
My boost gauge is flat lined tried different fuses. The connections are good and it is sharing power to the afr gauge...idk about aem I really wanted to stick with aem since I want everything to be the same... pretty pissed haha
Had the same issue with my last car it's the sensor 100% really annoying to have to deal with. They make you send the entire gauge back to them 🙃
Smeedia it really sucks bro paying all that money and have problems... but when it works out the feels is almost unbeatable lol
Yup just one of the many commenter here.. installed worked for 3 days than permanent lean when car runs but brake clean and a rag reads full rich
I've had pretty good success with Bosch replacements on Amazon.
Would you try the pro sport gauges? This video making me scared of getting aem ones lol
It was just the sensor and ive never used prosport before so I'd have to read some reviews
Yeah they are pretty fool proof just run a good Bosch wideband 02
i never have problem with PLX ones i change to AEM on my rex and the problems start
Mine is doing the same thing, haven’t had it on the car 6 months yet.
Seems to happen fairly frequently with the AEM Sensors 😖
@@Smeedia did aem send you replacements for free or did they still charge you?
I bought a replacement off of Amazon and it's been going strong for 2 years. I've had multiple AEM ones go out so I have up on those sensors lol
Hey man, I’m just curious if you’re her figured out the issue. I just installed same wideband and idled then drove for 10 minutes working normal then all sudden went to 3 dashes. Works for a few seconds on start up then goes back to the 3 dashes. I’m assuming o2 sensor bad?
Its thr O2 sensor, one one of my more recent videos with my BRZ i had the exact same issue
Smeedia sweet, thanks for the reply man. Hopefully they replace mine as it only ran for 10 mins
Same thing happened, 10 min and the sensor died 🙃
Smeedia gotta love aem
Thwyre going to make you send the whole gauge back to which is the annoying part. 🙃

AEM sucks...my xseries AFR gauge only lasted a few weeks same challenges...:(
Ugh, the sensors have been bad for a while now 😪
Just the sensor everytime, probably to close to the turbo or placed wrong, I've done about 4 sensors in 6 years bosch lsu 4.9
My original Bosch sensor worked for about 8 months before it started reading incorrectly and not reading at all. I replaced it with an Amazon equivalent which worked for about 3 weeks but started doing the same as the old one then one day it repeated the heat cycle multiple times completely. My sensors about 24 inches from my turbo at about a 9 o'clock angle.
Mine does the same thing. New install can't get it to work.
Those AEM Sensors seem to just have some quality issued out the box
Installed mine an hour ago. Same issue after it worked for 30 minutes
Ended up being the sensor, swapped to a Bosch replacement off of Amazon and been goijg strong for 2 years 🙏
Just installed one. My sensor lasted literally 5 seconds.
Amazon bosch sensors are what I've used as replacments. Have gotten 2+ years of use from them. The AEM ones are no good
No conclusion. Don't need to watch video thru🤙
LMAO yo i dont mean to laugh but IM GOING THRU THE SAME SHIT, and.. my gauge did the sAME SHIT. like itll start at 14.6-7 and then BOOM - - - and then u rev it, itll go down like it works, and u let it idle, 18.2-3-4 and then - - - again lol. I cant lie tho my sensor is old, 2 years old. But i jus wanted to know what was the issue from u guys side and now ima jus buy a sensor.
After my motor swap, my gauge reads only Sens...
Typically I've seen that if the sensor harness is not fully plugged into one another
So can you point me in right sensor direction
amzn.to/3u9yQfA
@@Smeedia Why did you have to splice the wires? It looks like the sensor should plug right up - The Amazon add says it's supposed to fit the AEM. Each 4.9 sensor has a calibration resistor built into it's connector, so the connector that comes on the sensor not supposed to be eliminated. Just trying to understand where you spliced things??
Swapped pigtails because they were not same same, at least the one I got was not same same
Just watching as my aem gauge just stopped turning on.
No power at all? 😳

needed gloves i guess
Aem did the same with me two bad sensors in a year it’s bullshit I’m in the same spot again with a shit sensor
I posted as Goldie to explain the setup I used if anyone does the o2 idea you will have to tune it everytime the engine light comes on with a tuner or just weld the bung 18"in from the cylinder head but, you might have pinched or kinked the harnesses that might be messing with it or a bad sensor then....
My issue ended up being the sensors that AEM kept sending me, eventually ended up just buying a sensor in Amazon and splicing the harness to the new sensor to make it work lol
Smeedia do you have the wiring diagram for splicing
Smeedia do you have a video or wiring diagram which color Aem sensor wire splices to the new sensor you got from Amazon have a replacement coming but not confident on the replacement either,thanks
I dont 😪 i need to make another sensor though for the STI so ill make a video on it

You bought a knock off o2 sensor. Let me guess.....you bought it as a kit off Amazon or something. Pull your o2 sensor probably doesn't have Bosch or any markings on it. AEM didn't sell it as a kit thats why they didn't send you a new o2. These fools will provide a chinese o2 and claim its a bosch and it'll never read right. Buy the right bosch o2 for 120 bucks and stop all the silly business of checking grounds etc.
That's the sensor that came with the AEM wide band. Ans it is indeed from AEM with their provided sensor. Funny enough thr cheap Amazon sensor I replaced it with went 3 years strong.
Mine just goes from 14.7 then goes alllll the way to 18 then those three lines.... and does not move... been doing this for 2 days..... but idk maybe i’m running way too lean.
