Example of a Bad In Cylinder Pressure Waveform (2014 Honda Pilot Lack of Power-Backpressure)
Просмотров 4956 месяцев назад
This is a quick video showing an in cylinder pressure waveform from a 2014 Honda Pilot that lacked power. You can see in the waveform that the exhaust back pressure was as high as 40 indicating a plugged exhaust. Catalytic converter was completely plugged up.

CAN Bus Diagnostics 3 (shorts and opens on module with no termination resistor) 2007 Toyota Camry
Просмотров 2078 месяцев назад
In my last video I had a question on whether or not the shorts or opens on the network would change based on if they were at modules that had termination resistors or didn’t have. This video looks at that.
CAN Bus Diagnostics 2 (Opens and Shorts) 2007 Toyota Camry Using the Picoscope
Просмотров 3918 месяцев назад
In a previous video I intentionally shorted and opened the CAN bus on a 2013 Ford Fiesta to see what it did to the network waveform. This time I did it on a 2007 Camry to see if the results were the same. They were not.

Cool You're a great teacher. Thank you. My dad was a machinist for John Deere's for 31 years
How do you know its not a vacuum leak? Is it possible that the MAF is dirty?
Nice how the shit was green before you put it on. Do you wear a ring with a spike on it so you can sell new radiator hoses, too?
U shut it off to quick
I have the same scanner, how did you get yours to show % mines show in decimal
Except that's not the continuity setting. Continuity is the sound or wifi looking sign. You set into ohms, the same sign thats on the red lead. ruclips.net/user/shortsdqCIx06oeNg?si=y5QnmYxGX4-QShHR
Actually continuity is testing for a continuous path with low resistance. Notice when you turn on the buzzer you’re still reading ohms. The buzzer just makes the test audible for convenience purposes especially when your in a tight spot under a dash or something and it’s hard to do the test and read the meter at the same time.
@@hunterautomotive4842 got it!
Thanks for the info man, diagnosing mine for sudden loss of power after a while of driving. Mine is the inline 6 engine, so only 1 o2 before and 1 o2 after. I thought it couldve been the cat, but the charts look like your top 2 o2 readings. They look perfect. Thanks for this info again
50x pulses im 10ms? Doesnt sound right or the china tester box is mislabeled etc One pulse is anywhere from 2-20millseconds long i.e how long injector is open and spraying. 10 milliseconds x 50 = 500 millseconds which is half a second and your test was 4-10seconds long. And listening to the audio sounds more like 20-50 pulses. The typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms. typical pulse width is 2 to 4 milliseconds at idle and as high as 15 to 18 milliseconds at wide-open throttle. But maybe the tester is telling you open time on injector of 10ms but not time between pulses so could be 250 milliseconds in-between puleses tgat last 10ms long
Can the reading be done on a standalone o-scope?
Just watched this video in the cab of a truck I’m diagnosing 😂 you’re a saint man thanks for the clear cut straight to the point Info
Ford Cologne 2.8l engine for reference. There are 4 cam bearings of 4 different diameters. The outside bearings are larger than the 2 inner bearings. To remove them you have to place your cam tool all the way through the engine until it contacts an outer bearing. Press that one out. Then move back into the engine to the inner bearing. Tighten your tool and press that one out. The inner bearing is smaller than the outside and it will pass through easily. Then remove your cam tool and flip it around through the other side of the engine to remove the other outside bearing. Press it out then back the tool up to the last remaining inner cam bearing. Press it out and again, it will pass through the outer opening easily.
Awesome! Could you show how to test a MAP sensor as well?
Could you explain how to know if the o2 sensor is bad? Great video thanks!
Can you to tell me how to test the connector to the IAT sensor? I have high input. I am wondering if I just need to change the connector/wires.
Hrrmmm - shouldn't you be supported the ends and measuring the middle?
I actually measure every main journal
It's great that these can be measured from driver seat
there are some spikes inbetween the E1 & E4 marked area what are these( when sensor was installed in frame). Thakyou for uploading
Thank you - trying to work out why my aftermarket instruments work for all my OEM readings except the ECT - ( it just reads 0) looks like I need to Incorporate an adjustable resistor for the oem temp sensor to be recognized by the aftermarket dash - its a Honda st1100 motorcycle restoration/custom project
Awesome. You do a great job at walking through the process. Where can I score one of those electro trainers?
Great video !!!
no wasting time, straight to the point, love videos like this, thank you this was very helpful!!
thanks 👍
Does this mean your cat is bad or could it also be dirty ?
Hey great explanation I just had a question I have a 2014 charger 3.6 giving me p0172 and p0175 I don’t feel any misfires but the long trim show -32.812% on both banks and short trim -33.593. When I step on it the long trim goes to 0%
I'm having the opposite problem
It idles the same plugged as it is unplugged. Is it my wire connector or the actual iac valve? The iac valve i just bought from auto zone and thats when my problem started
I know my post is very late. What is the engine capacity? Thanks!
Gracias amigo, very helpful
Love the video dude! Explaining the difference of a narrow band that you're working on here I believe is important information to note you're NOT talking wideband! Im definitely a shade tree mech here so I'm no mechanic in that sense of schooling but im learning lambda a/f sensors! They definitely read differently! Great video for a narrow band buddy! Not talking shit bro just it's good to share that info I think
Need a forum or group where can discuss diagnosis of OBDII data.
Great video!.I was about to set up for this test.now I'll move on to something else interesting like calculating the amps produced per armature revolution at a projected calculated representation of 100 percent duty cycle(.just for the fun of it.) Any help would be appreciated.
Cool. I just measured the dome light duty cycle (Amps). Using a fuse buddy and amp clamp at the fuse box.
very VERY helpful, short, sweet and to the point.
Excellent video 👏👊
What if the car wont start
Nasty 🤢!! Customers replying “…. Ya lying to me it still runs!”
They made cars too complicated. I'm thinking that if the computer and sensors are working properly to maintain the correct AFR, then should I care about a "high" LTFT. Bank 1 is +14% and bank 2 is +12% but the car drives good and there are no codes. STFT alternates between +/-3%. I don't have anything to measure AFR. By the way, I'm not a professional mechanic that has access to all the "toys" (test equipment). But I would like to get the LTFT under 5% and hopefully without breaking the bank.
Awesome.
But I get it though
I think they called this hopscotch back in the day
This is how make a effective video, no fluff, simple, short, and easy to follow - thanks!
can you use these readings to find out if your o2 sensors are broken?
Are you worried about the channel overage?
Your GOOD sensor 2 example and BAD sensor 2 example is the complete opposite as to what I have going on. Possible someone swapped plug connections on my car. They plug into the same area on car.
My Forscan reading shows bank 1 sensor 1 reading in Current mA or Imped V. I don't have a reading in mV like your scan tool shows.I'm getting a P219A code, Lean bank 1, and the mA reading goes from 0.00 to -0.11, and the V reading is 1.02 to 1.01. Does this indicate a bad O2 sensor? Thanks!
Got this code only after changing the ICM on my 2.2 ecotec. Any idea what would have caused that?
I have a 2002 Chevy Cavalier ls where is that at
