Nice video! For anyone watching this video I only have 2 recommendations. 1) Please, for the love of God, only use Honda OEM replacement parts for any part that has an electronic sensor. After market parts are often not read properly by the ECU and can cause the CEL to come back or the sensor/part to run the wrong voltage. Spend the extra money when it comes to sensors. And 2) This project is much easier if you remove the distributor. You will have better access to the sensor slot and can block the slot with a rag to prevent coolant from dropping down onto your starter and transmission. Cheers!
My original 1999 honda accord 4 cyl. engine coolant temperature sensor was 19mm. I needed deep 19mm socket. The new part was also 19mm. I also found it necessary to pull off the entire distributor which really isn't that big of a deal.
I'm so grateful that aligning the distributor is not an issue. Previously, any turning of the distributor changed the engine timing and had to be reset.
@@jimekrut Get a paint pen and mark two different lines on the mating faces of the distributor where it bolts on. I have a Haynes book for my model handy in case I get confused. It's not hard but it's great to have a manual because sometimes one can get stumped on even what in retrospect was pretty straight forward.
I'm able to open the bleed screw (near thermostat) with the engine off and fill the radiator until the bleed overflows, and have almost nothing to add once the engine warms up. Nice surprise.
Thank you! I might never have found the sensor without your video. Mine was covered in grease and virtually invisible. My temp gauge hasn't been working normally, so hoping this replacement may solve that issue. I have a '96 non-VTEC, so while not exactly the same, the temp sensor is in the same area. Mine was 19mm, replacement also 19mm, which was helpful since I would have to buy a 21mm.
I also had a bad bad temperature gauge sensor. My dial would barley rise above the bottom cold reading. I first thought it was a bad thermostat, so I replaced it, but it was the sensor. I then replaced the Engine coolant temperature sensor that feeds info to the computer. That improved my mileage by 4 mpg. Be careful buying cheap part on eBay. They sometimes say it fits your model and it doesn't.
@@gemeinschaftsgeful I'm beginning to wonder whether my previous thermostat was a lower temperature unit. The new one does finally get to operating temperature, but much more slowly. The parts clerk indicated I was purchasing the original temperature model.
MIne too is covered with grease down there. Gonna get some degreaser, then hose it off. Replaced dist O ring. Heater hose, thinking that was the prob. Honda heats up during normal operation. Got to turn on Heater full blast to keep from over heating.
Hey man! Arlington, tx here. Ive got an 02 coupe. Thanks for your video. I just got the sensor. What are the symptoms of the car that prompted you to replace the sensor?
Thanks for the video, did your car get over heat problem for the reason to replace the sensor? My '93 Accord shows problem with the upper radiator hose gets very hot but the lower radiator hose is not hot, temperature gauge's just barely rise up above the Cold level. Thanks for any info.
I'd like to know the answer to this question also. I've got a 2000 Accord that has been overheating. Did you ever get your problem resolved and if so what was the cause?
When you replaced The coolant temperature sensor did you have to use Teflon tape so that coolant doesn't leak to the threads or do you just screw it in and thread the coolant temperature sensor in regular because I heard that you're supposed to use Teflon tape that they use for plumbing but I'm not sure?????
I have a 96 Honda accord LX, 4cyl 2.2L, will replacing this part make my temp gauge work again? My Temp gauge just sits at the bottom and doesn't move, the cars rpm does drop as the engine gets warm so it still knows how to regulate its temperature and the fan still works, its just the gauge doesn't move
for me my check engine light came on. but also the temperature gauge started to go up and down randomly while driving like my car was overheating and then cooling down. so i bought an OBD reader for 100 bucks from Oreily's and it told me i needed to replace my ETC sensor.
I have this exact 2002 Honda accord, the temperature guage is not working, the sensor got damaged and I replaced it, yet not working, could it be that the sensor is not for this model?
I replaced mine because it was showing hot when the car was clearly not getting hot. Now it is just going up and down and sitting below cold. Also my car has another sensor next to that one, you have a bolt in that location! Did you delete something?
What sensor is that under the car, near the drivers side, hooked to the heater hose where there is like a V, for 1998-2002 Honda Accord? It must be a coolant sensor, but I don't see which one to buy to replace it.
My car started to not blow cold air a few days ago now i turn the air on and it still isnt blowing as cool and acting like it wants to overheat i ran a scan on it and got a p0420 code could this bein replaced solve my problems with the code and air temp? And after replacing do u need to have more coolant put in, thank u in advance.
I have 3 sensor in line, coolant sensor in the back, second this one, and third right on the nut position, mine keep overheat when im not using aircon, notice when i use aircond fan is working, should i change this sensor also ?
@@ivanibrahim7465 It allows the coolant temperature reading to be properly displayed on the dash gauge cluster. (Thats the first sensor towards you) (with the bolt).
Do you do that for preventive maintenance or you got a po117? I just replaced my fan switch because it doesn't work, It only works when the a c is on.When I bought the part it comes with that coolant sensor.Should I change both or just the fan switch sensor?l have no c e l .Maybe not.
That slot is for a Thermo Unit (part 37750-PH2-014) that is used on the ULEV and SULEV F23A4 engine. The engine in the video is an F23A1. The F23A4 is the exact same engine as the F23A1 but has a few modifications to ecu and the block for sensors that reduce power and emissions.
I just replaced my coolant sensor and thermostat. Thanks for the video.. while I was doing this I noticed there was a small hose that was laying across the top of the radiator hose that runs down to the top of he transmission but isn’t connected at the end closest to the motor. Transmission end is connected but the other end is open. Cant see any place obvious that it should go. Any ideas? Thanks

Anytime you do any work to your car that has to do with the coolant. Make sure you drain the air out the system after you’re done.

@@carroll6 You have a problem. The radiator adequately cools this engine.
Why is that motor so clean on that old ass car?
😂
Do you have to bleed the coolant system after installing the sensor? Thanks
Nice vid, nicely done and edited. GOOD!
Thanks very good job
Is that the sensor that sends signal to the computer or the gauge
Thank you for this video 🙂
I’ve gotta 98 Accord 2.3 - temp gauge is dead. Is this the same sensor or is it the one above the thermostat??
Hey man! Arlington, tx here. Ive got an 02 coupe. Thanks for your video. I just got the sensor. What are the symptoms of the car that prompted you to replace the sensor?
What was yours doing, for you to know it was bad?
Thanks for the video...... also you missing a bolt on your hose housing
Really appreciate your video, it helped me immensely. Thank you

@@medardomelendez5706 denada amigo. Se me iso facil depues de ver el video.
Thanks buddy. This helped me find it. I did it with the distributer on, it's still easy. Thanks.
Thanks for making this video. BTW, i noticed you are missing the bottom bolt on your thermostat housing.
Does this sensor related to iacv too?
There are 2 of these sensors. The other is on the thermostat. Unless I am mistaken. Well, are they both the same part?
Is there a coolant temperature sensor in a 1999 Honda Accord EX V-6 3.0 and where is it located?

No. The sensor has a rubber o ring gasket to prevent coolant leaks.
Also, I don't think that tape is made to withstand those temps
I have a 96 Honda accord LX, 4cyl 2.2L, will replacing this part make my temp gauge work again? My Temp gauge just sits at the bottom and doesn't move, the cars rpm does drop as the engine gets warm so it still knows how to regulate its temperature and the fan still works, its just the gauge doesn't move
Engine light should illuminate when sensor goes bad. Scan of dtc should reveal bad sensor.
What were the symptoms you got that lead you to figure out the sensor was bad?
I’m wondering this also
for me my check engine light came on. but also the temperature gauge started to go up and down randomly while driving like my car was overheating and then cooling down. so i bought an OBD reader for 100 bucks from Oreily's and it told me i needed to replace my ETC sensor.
great vid. helped me a lot.
Glad to help.
What were the symptoms?
Hot on left, cold onright?
Great video! Sick guns bro 😅
Also where do you live? I hear seagulls and all kind of things. Just curious? 😅
I have this exact 2002 Honda accord, the temperature guage is not working, the sensor got damaged and I replaced it, yet not working, could it be that the sensor is not for this model?
Is this the only sensor on the car that has that style plug. The single flat blade one way and than another turned 90° the other???
Hey, the needle of the temperature doesn't show any reading, can you help me out?? And where can I find the plugger for that sensor??
It's right in front of the engine coolant temperature sensor.
I replaced mine because it was showing hot when the car was clearly not getting hot. Now it is just going up and down and sitting below cold. Also my car has another sensor next to that one, you have a bolt in that location! Did you delete something?
,I’m doing now and no check engine light after I change the sensor... millions thanks 😊
What sensor is that under the car, near the drivers side, hooked to the heater hose where there is like a V, for 1998-2002 Honda Accord? It must be a coolant sensor, but I don't see which one to buy to replace it.
Thank you. Needed to see how it's done so I can help me kid fix his car lol.
Hello this car has 2 sensors together and another one for the water pass which I should change

And after replacing do u need to have more coolant put in, thank u in advance.
Can you do this in a 1993 Honda Accord cb7?
Is this for p1486 ??
I have the same code, can't seem what the problem is.
I wrote this 2 months ago an still haven’t fix lol I think I got an idea if it works Il come back an tell you
How do you diagnose the problem to determine that it was just the sensor causing the overheat considering all the other possibilities?
@Eduardo Herrera if it is obd1 ?
I went to autozone becuase I got a check engine light and they told me it was this becuase of code p0128
can a bad temp sensor keep the cooling fan from turning on?
Yes and No. if it does not read the correct temperature that the ECM is set for it will not kick on the fan.
@@MachineHeadRepairProjects My '96 has a separate coolant fan switch sensor near the thermostat.
Question, what's the one right next to it? Towards the front. Yours doesn't have anything there just a bolt. I'm sure I'm leaking oil from it
One is the coolant temperature sensor, and the other is a fan switch. I have a video on both switches.
@Bluebell blue bro yooo mine leaks bad right there. Got vtec gaskets but it's a clean puddle under distro

Is this the same at the temp sending unit??
no that is the one shows temp on gauge in the cluster
@@ahoorakia where is that located??
@@gamebred5x
if you have newer model it's the same sensor as ECT there is not other one
I think 98 and up there is only one,that you see on the video
@@ahoorakia I have a 99
My temperature gauge in my car is not working what could cause the problem I switched out the cluster but still nothing any help
That's a trend for this car.
Cuando el carro tienbla esas podrán ser las funciones
Where is the one for the v6?
Did you ever figure out where the sensor is on a V6? I am having the same issue
Yes, 19mm
just have the coolant sensor not working . The fan only turn on when I switch the AC on
What sensor are you missing? To the ri
That slot is for a Thermo Unit (part 37750-PH2-014) that is used on the ULEV and SULEV F23A4 engine. The engine in the video is an F23A1. The F23A4 is the exact same engine as the F23A1 but has a few modifications to ecu and the block for sensors that reduce power and emissions.
To take off the whole distributor it's 2 12mm bolts
can that temp sensor cause your fans to keep spinning the moment the ignition is switched on?
Yes, the sensor can read faulty. It can either read hot and keep the fan on. Or it can read cold not turn the fan on.
@@MachineHeadRepairProjects hmm so it works along with the thermo fan switch then
R those rattlesnakes I'm hearing?
I got code p0128 and bought this but they told me it could also be a ecm
My car is reading hot even after being off for hours and the cooling fans not turning on 🤔 then the car acts like it wants to stall
Disconnect the ETC sensor located under the distributor and run it like that. You might still have a ck engine light, but the car wont stall
So my fans don’t kick on at all. But Ik they work so what is the outcome
You the man
Working on these Japanese cars SUCKS. I hate removing parts to get to these sensors.
Is it 21 or 19 mm?!?
Mine was 19mm. 2000 Accord LX
I just replaced my coolant sensor and thermostat. Thanks for the video.. while I was doing this I noticed there was a small hose that was laying across the top of the radiator hose that runs down to the top of he transmission but isn’t connected at the end closest to the motor. Transmission end is connected but the other end is open. Cant see any place obvious that it should go. Any ideas? Thanks
The line is for your transmission to BREATHE and is supposed to be like that.
think you good

It's a fucking 19 mm socket. That ended up costing me a bunch of money and wasting time
