For anyone this may help : I've been diagnosing a radiator fan not starting under any circumstance.. The ECT sensor circuit is shared by the cooling fan circuit. Fan doesn't turn on? Try unplugging the sensor wires. If the fan kicks on you've found your issue. Took me forever to find that out. Replaced EVERYTHING cooling fan related until that was my last attempt. Cheers! Thanks for the video!
The specs for the temperature sensor that I found says that the resistance goes down at higher temperature (68F: 37.3 kohms, 176F : 3.8 kohms). So it seems like removing the connector would simulate a very high resistance and make the fan control think that the temperature was low, and not turn on. Maybe I'm missing something?
Oh my gosh, thank you so much for the clear and easy explanation on this. I just found out that this part even exists and have struggled to find good information for my very basic know nothing about cars brain to figure out how to fix on my own but I think I get it now. Thank you so much this really helped .
Thanks for the help! Love your camcorder work, too! I like how you explained the situation, the reason, the remedy, and step by step. Great accent, too, my brother!
Look closely at the old sensor once it’s removed. If the O ring is not present, it’s still stuck in the engine and you’ll need a pick to ‘pick’ it out quickly. If you don’t, the new sensor will leak.
I don't know what the author did, but I would definitely disconnect the battery first when working on electrical components. Even if you are near any electrical connectors it is a good idea to disconnect the batter; can you imagine accidentally touching a hot wire/connector with your ratchet and then a ground like the metal engine or body parts? I've done it and it is not good :)
If it is not coming off then it is possible you are not pushing on it correctly. Walk away from it, take a break, and go back; you don't want to break that connector!
I didn’t. A little bit of coolant will come out, but it’s negligible when putting in the new sensor as fast as possible. I’d put an old rag underneath to catch the liquid.
Thanks for getting to the point and not telling your "Life Story" for 10 minutes before the repair. Well done.
Agree

nice. what year/model do you have?

What’s the ECT?

A perfect instructional video. Well focused camera, good camera angle, and good verbal explanations.
Thank you for this very direct and easy to watch video. Unlike the other hour long videos I have to sit through for 5 mins of work. Well done!

Awesome video! Great shot of exactly where the sensor is and highlighted the clip itself. Very helpful, thanks!!

Finally a great and clear video. Nice job and thank you
Another helpful tip,get a rod or piece of Wood to extend the hood open further than the factory hood rod.
Thanks for this DiY tip bro..will save us from mechanic fee.
Awesome!!! You Sir, save me a lot of time!!!
Thank you!!!
Great informative video!!! Thank you.
good old rocker cover leak. Hope you've fixed it by now :)
Thanks! A very helpful video.

Do you have to disconnect anything before doing it or can you just jump right into it by taking the sensor off and screwing the new one on
I don't know what the author did, but I would definitely disconnect the battery first when working on electrical components.

ALWAYS ALWAYS disconnect the battery before you mess with anything electrical you can damage circuits and sensors and anything like that
White cable goes to the driver's side?
thank you very much
Thanks! How do you know that you have a P0118 on the ODB-II port? What is that? ODB?
Does this sensor control the radiator fan?......If fan stays on after you turn off ignition?
Is that the sensor on the water outlet housing?
Thank you
Could you let us know what deep socket set you use? I bought one to do this only to find they were not deep enough to fit over the bolt.
Hi, I am using Craftsman sockets
Thanks
Trying to save some money 😂
Tanks👍
My light hasn't went away yet so I'm guessing I have to do the thermostat as well I changed the sensor at 10:00 a.m. and now it's 11:52 a.m.
Is this a 2.0l or 2.5l
there is no codes but my mazda's temp gauge remains cold even after driving. wonder if this can this solve it.
I'm having the same issue. Did you find out what it was? My coolant blue light stays on for a good time before it goes off.
Nice work
Are all sensor the same?
No
Is this sensor at the water outlet?
Won’t you have air bubbles in circuit? I have to the same to mine, but I am affraid that I will get some air bubbles in the circuit after the repair…
Hi, the air bubbles will find their way into the reservoir once it starts to circulate through the system.
@@MegaSafetyFirst thanks mate 🙏
mazda has self-bleeding design in cooling system
👀👌🏻 thank you men
What problems / symptoms did you have with bad Engine coolant temperature sensor ?
Overheating, my gauge went up high and low while driving and my heater stopped working
This answer my ?
@@kayehubbard6260 im confused what was your answer ?
The sensor my car doin what he said his was doin
Useful
My connector to it is being stubborn as hell, any tips?
If it is not coming off then it is possible you are not pushing on it correctly. Walk away from it, take a break, and go back; you don't want to break that connector!
Do I have to drain the coolant first ?
I didn’t. A little bit of coolant will come out, but it’s negligible when putting in the new sensor as fast as possible.
I’d put an old rag underneath to catch the liquid.
i know im late but i just replaced mine and coolant is pouring out the senor and we sealed it. I don't know what to do
When you remove it, coolant should come out from that hole just quickly replace it with the new one and fill the coolant overflow tank.
See my comment above.
I can’t seem to get the connector off
where can i found it on my 1.6?
I am trying find out the spot for the ECT for my 2018 mazda3 2.5L. I can find out. Someone can help me out with some pictures or anything
What a .otor is that ? 1.8 ,2.0 ,1.6 ?
I cant find on my mazda 3 either .where the heck is it ...🤔
Between the battery and engine. Some of them use clips and are not screw in type, you might need to remove the water outlet to get to it
I mean you could empty the coolant first.
Funny how Mazda engine sensors are located in the most hard to reach places loooool
Thx 🙏
Thank you ser
