Note: the top sensor in the engine has a BLACK female receptor, while the unit at the bottom of the radiator
is a WHITE one (2009 Civic). They are not the same sensors top and bottom as stated in the video.
Would you happen to have the part #s
@@leavemealoneimpoobutt6549 37870-RTA-005 (bottom) 37870-PLC-004 (top)
You're right they are not quite the same temperature sensor one is slightly longer but they will both work I've used both of them in several civics
I just went to do mine on top and the clip was wrong and didnt work. It had a fat slot for the clip but the one i took off had a skinny slot. Not sure if thats for the bottom or not. Wasnt able to get the bottom one off. Didnt have the time to mess with it. Wondering if you could tell me that one would be for the bottom.
@@compton1707 Do not know how you manage to do that on any civic between the stated years 06 through 11 as the clip will not fit interchangeably. There is differences in length and clip attachment.
Thank you guys, for youtubers, my 2010 Honda civic yellow engine light was on, diagnosed ECT 2 sensor, I didn't replace coolant for 10 years since brand new. After replacing coolant, keep driving car with yellow lights for a month. Finally yellow is gone never come back. Honda quality still good ECT2.
2:09 The top and bottom sensors are NOT THE SAME. I just did the maintenance on my Honda Civic 2007 and they have different connections. So if you are unsure, check each connection or research the connection. This video was very helpful, although the statement that they all have the same sensor is incorrect.
Yeah I was just gonna say... when you look up the temp sensors there are two parts listed I had to check again to make sure it was right lol
Can I get the part number for both sensors
I did some radiator work on my 2006 Honda Fit last night, and when doing the "burp" procedure it took 50 minutes(!) of idling before the fans finally came on, and over an hour before they ran a second time. Each time they only ran for about 5 seconds. Coolant temperature (ECT1) was about 95 degC, so I don't think there's a problem, just be aware that you might have to wait a while!
Had the same problem. Idling over an hour and no fan. Opened the Hanes manual and it instructed to run it at 1,500 rpm while waiting for the fan 2x. Then I finished within 20 min
Great tip. I've subsequently seen 3000 rpm mentioned in Honda service docs for warming it up quickly.
I love your videos, very detailed instructions 👍🏼
These guys are awesome! Thanks!!
Great guys, great explanation 👍 keep going
Awesome guys !
@2:20 THANK YOUUUUUUU!!!!! such a headache trying to figure that one out online without touching the car. Thanks a lot!
Happy we could help!
DO NOT LISTEN TO THEM THEY ARE WRONG!!! IT IS NOT THE SAME SENSOR.
Good thing this was here. I didn’t know about burping.
Thank you❤❤❤I have the 93 civic so didn't have to go underneath car. Appreciate radiator refill info.
In What temperature does it activates the fan? And is there a temp sensor that activates a little earlier? What codes to look for in the sensor if ever?
Very good
Great video. I am trying to replace the ECT sensor up top on an Acura TSX 2008. 1.) Where is it located & how do you know that it is the right connector? Is it the same location as what looks like a Honda Civic in the video? 2.) In the video the wiring for the ECT male looks like it’s connected to a circular part. What is that part?
Great video. Well produced. Ths will save me from a $275 quote from the dealer. This quoted
What are the part numbers for a 2012
4 door Civic? Are they the same? Thanks.
You guys are the best!
The sensor at the bottom by the radiator is called a radiator fan sensor. And it’s not the same part as the sensor on top.
Спасибо огромное очень сильно помогли 🙏🙏🙏
Рад, что мы могли помочь!
Very nice step by step very nice explanation and great help to do DYS thanks A lot
what is the original oem parts identification number of each sensor
Donde se ubica el sensor de temperatura de un Honda fit 2015?
Where is the temperature sensor of a 2015 Honda fit located?
I don't have an OBD2 scanner, are there symptoms to know when each of these sensors need replacement?
My check engine light never came on but my smaller fan never runs and the bigger fan only works when the a/c is on. My car overheated yesterday. Radiator and reservoir were both empty. Any solutions? It hasn't overheated since yesterday after driving it all day but reservoir is empty again but radiator still has fluid.
Is there a o ring on the ect2 censor
What causes the AC and radiator fans stay on even when the car is cold? This for 2007 honda civic sedan.
Hi,
What are the parts numbers for the 2015 hatchback / tourer models ?
Are they the same for 2006-2011 models (37870-PLC-004 for the top ECT1 and 37870-RAA-A01 for the bottom ECT2) ?
Hello, Your best bet would ne to check with your local Honda Parts department!
Is this what causes the Emissions light to come on? Sensor 2
Chris - My Honda Civic 2010 heated up so I replaced the head gasket. Problem - the area around the valve cover is smoking and I could hear the timing chain making some noise, I installed new tensioner. Please give Advice for possible causes. Phil
You might have needed a new timing belt
Is the second sensor still in the same spot for a 2021 civic?

Hi Antonio! Unfortunately no we don't, I do know it's a different process, I will forwarded it to the team and see if we can get it added as a video to do, but I cannot promising anything.
Hey. I am from Cape Town. Just got my bluedriver from Amazon to use on my 2010 Honda Civic. The m6 function is not supported on my vehicle.
Hello!

Can sensor 2 cause a no start?
How do you test the sensor? I'm not sure mine is working correctly. There must be resistance specifications for various temperatures
is it on the thermostat housing ?
Porque le pones el mismo sensor en ambas partes? creo que son diferentes, el del radiador tiene conector color blanco y el de la culata color negro, de hecho tienen numero de partes diferentes al momento de comprarlos.
Sabes que partes son?
hello the two sensors are the same?
So even after the repair the engine light has to be manually reset? The engine light doesn't go off automatically?
Yup it has to reset but when you do the light shouldn’t come back on
You said its the same part number, i have a 2008 civic lx and the plug is diffrent,
Thank for guide now I no may car Honda civic is two senior
I have a civic 2013 Lx and i just change the thermostat twice and the code p0128 still popping up..Any idea ? Thanks for the tutorials!
P0128 is mostly the thermostat maybe is getting air in the system when you change it. You can also change both sensors (like he did in the video).
@@eligarcia5433 i was having the same problem,, p0128 but amazingly the engine light just went off on its own, fickle car. It then passed inspection, crazy.
@@pauljacobs4947 what you do to fix it?
Will this work the same on 2012 civic
#1 and #2 use the same sensor on 2006 Civic?
Thank you for this tutorial, its much deeper with detailed info. Please, I have 2006 Honda civic n had code p0128 which meant I need the coolant thermostat changes. I did changed but the code P0128 came on after weeks? Can you help me know which kind of temperature sensors u used in this tutorials which am suspecting might be poping code p0128? Thanks
Hello!
Looks like you probably need to do sensor #2 at the bottom of the radiator - you can use part # 37870-RAA-A01 or go aftermarket
My Mode 6 on my scanner shows a bunch of yellow yield signs and very few green checks .. why isn’t it scanning those systems?.. thanks
Hello!
Green means the test is reported by the vehicle as passed, yellow means we are getting the test results from the car which is reporting that test as "not complete".

I got a P0128. The CEL disappeared 4 days later. Nonetheless,I changed my thermostat and poured new coolant. I want change both ECT as my fan never turned on twice. I want to change it 3 days later. Can I reuse the fresh coolant after I replace both ECT? I know I should have done everything at once but tryna avoid unnecessary work. 2007 Civic LX
Did you get it fixed?
@@Amahyze777 just changed my thermostat. Been good ever since
The top sensor and the bottom sensor are not the same, the top sensor is black with a thinner clip and longer, while the sensor on the radiator is white with a thicker connector and shorter compared to the top.
Can you show me where the wire is coming from that plugs into the radiator please. My radiator didnt come with a sensor and i dont know what wire to plug in. Is it a certain color or a diagram i can find please help.
Does the Honda fit 2006 model having 2 ect sensors,.I just found one?
They mentioned in the video that this car has 2 similar sensors. The second one is below the car
Hey guys I have a question. 2007 HONDA CIVIC HYBRID. AC not working nether cooling fan turns on when AC is turned on has coolant compressor kicks on. Also fans never come on but no overheat issue or check engine light. Does ECT have anything to do with AC and any ideas also have gone through the fuses seem ok not sure about relays.
Z
Do u know where the sensor is in a 2010 Honda Insight ?
Best way is to go to nearby Honda dealer shop and pretend to buy it for your year and model car, they will show the pictures and location.
DOES ECT 1 and ECT 2 TRIGGERS THE RADIATOR FAN MOTOR?
Only ect2
ECT 1 can trigger low temp gauge on dash
Hey,im replacing mine,i can turn on
A.C...both fans activate..,im getting
WOULD IT BE,
#1 OR 2 ?
Can a bad coolant sensor cause a knock sensor code?
Are BOTH SENSORS THE SAME ???
top and bottom are NOT the same. 37870-PLC-004 for top and 37870-RTA-005 bottom of radiator
But sensor 1 ?
Are sensor 1 and 2 the same?
No
They said yes?
I took my thermostat n ran my 2006 Honda civic will that cause the temperature sensor go bad
Running a vehicle with no Thermostat is never a good idea. It could be very possible that this caused a bad sensor or something else. Very hard to say for certain.
Thank you for info I was told u could run with out it but I'm putting one on now n the sensor but I noticed he said there two temp sensors how do u know which ones bad
You didn't answer this question. Are both sensors the same?
They mentioned in the video that both sensors are in fact the same
@@Ethereal184 they're wrong. Two different ones
what are the OEM PARTS? please
Original Equipment Manufacturer - an official part direct from the dealer (or maybe from the supplier that makes the original part)
Have you guys come across the sensor goin bad without throwing a code.
im having this same issue. All my research suggests that the sensors are the problem but when i get the car scanned its not throwing a code
I have a bad thermostat code P0128, replaced it. But check engine light came back after 2 weeks. Cleared the code. 2 weeks later, it came back. Could it be a bad temp sensor? Both fans comes on when the AC is on (this is the only time my cooling fan will come on, otherwise it does not come on when temp is at normal range). Temp gauge was good, not overheating. But now a week later my temp gauge doesnt even get close to the normal range which would normally be half way on the gauge. It would only go up 1-4-1/3 up now, still on the cool side. Coolant was drained, bled and topped off. I really hope it was not a faulty thermostat. Maybe bad ECT? Please help.
Did you get it fixed?
@amahyze7372 replaced both my ects and bought an oem thermostat. So far it's s working fine! CEL aint back. 🤞
The both sensor it’s the same ones?
I got the same question....
Correct.
5:11 "Don't get those backwards." :D
Hope you can help me,.does the Honda fit 2006 having a ect 2 sensor,.I cannot find it?
@@christofortuin1102 I'm not sure that it does. There's a temperature sensor and a thermo-switch that I believe operates the radiator fan, shown as parts 13 and 12 on this diagram:
jp-carparts.com/honda/partlist.php?maker=honda&type=FIT&cartype=5221&fig=E&fig1=1500
Looking at the exploded view for the radiator, there doesn't seem to be a coolant sensor there (as on the Civic).
jp-carparts.com/honda/partlist.php?maker=honda&type=FIT&cartype=5221&fig=B&fig1=510
It seems it's just one sensor,.thanks for your replay.
Good luck with your vehicle. :)
If my temp gauge is jumping when just sitting, would I need to do this? Or what are some of the common reasons to do this?
It's possible, but that could also be a wiring issue (maybe a bad ground or worn insulation?).
Generally you'll be getting no reading, or a ridiculously high one - your rad fans won't come on, you'll get engine coolant temp correlation codes, etc
Did you ever figure out what was wrong I’m having the same problems
You could have air in your system. Did you burp system with radiator funnel? Takes a good 30 mins at least to clear all air out with Radiator funnel.
Yo I changed both temperature sensors properly and the temperature gauge is still reading HOT. 🤦🏻♂️
did you ever fix this
They are not the exact same part, they are similar but the top is part# SU5584 and the bottom is SU10432
positive?
for what year?
Timothy Samuelson these parts worked for my 8th gen civic 2008
you dont know the part numbers for these? is it 37870-plc-004?
@@ItsHorrifying I have a 2010 civic will they work?
Which one sends the temp to the dash and which one sends the signal for the fans
I couldn't find a concrete answer - I would assume the sensor before the radiator (top) since it's a better representation of the coolant temp in the engine but for fan control there's likely some control logic based on the difference between the inlet and outlet temps on the radiator so both.
@@LemurMonitors ECT1 (upper) feeds the gauge, Easy to uplugh and watch you gauge peg out to max.
the white radiator sensor Part No is: 37870-RTA-005
And the black top sensor part No is: 37870-PLC-004
My 2010 Civic EX was also running cold So I changed the Thermostat and all of the codes went away.
What were the symptoms? I have the same problem I think
@@IzzyFX007 I changed the sensors shown on the video with OEM parts and I also changed the Thermostat all at the same time and that fixed my problem to this day.
The symptoms were that my Honda was always running cold, the temperature meter would never go above 2 or 3 dots. I was also getting very poor gas milage.
Once I replaced the sensors and the thermostat it all went away.
But make sure you get the OEM parts specially the thermostat.
I had previously changed the thermostat with an aftermarket part and it never worked.
@@zantiagotron07 Thanks a lot for the answer brother
@@IzzyFX007 you’re welcome I hope your Civic is back to normal soon 👍
Excuse me, what is the torque? You speak too fast, I can't understand, thank you👍
Beware both sensors are not the same! Caused me a lot of issues trying to figure that out. Okay video other than that.
Did you figure out the part numbers? I need help
@@zantiagotron07 SENSOR 1 THE ONE ON TOP IS 37870-PLC-004 AND SENSOR 2 THE ONE ON THE RADIATOR IS 37870-RTA-005
@@seymadd thank you I actually got it changed Two weeks ago along with the thermostat
@@zantiagotron07 did you have to change both sensors? im currently having this issue but the problem is when scanned i dont get a code. So im really trouble shooting here
