- This video describes the replacement of the coolant temperature sensor on a Mazda 3. In this case the vehicle is from model year 2006.
The reason for this repair is the occurrence of the trouble code P0118 on the ODB-II port.
After replacing the sensor the trouble code and the check engine light may not disappear immediately. Unless the code is removed manually, the error will be removed after a few ignition cycles.
Make sure to release the pressure from the cooling system before starting to remove the defective coolant temperature sensor. Also make sure that the coolant is cold. Never try to open the coolant system with the system hot and pressurized!! - Auta a dopravní prostředky
Thanks for getting to the point and not telling your "Life Story" for 10 minutes before the repair. Well done.

A perfect instructional video. Well focused camera, good camera angle, and good verbal explanations.
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!
nice. what year/model do you have?
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?
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
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!
Another helpful tip,get a rod or piece of Wood to extend the hood open further than the factory hood rod.
Great informative video!!! Thank you.
Awesome!!! You Sir, save me a lot of time!!!
Thank you!!!
Thanks for this DiY tip bro..will save us from mechanic fee.
Nice work
good old rocker cover leak. Hope you've fixed it by now :)
Thanks! A very helpful video.
Thanks! How do you know that you have a P0118 on the ODB-II port? What is that? ODB?
thank you very much
Thank you
Thank you ser
👀👌🏻 thank you men
Tanks👍
Does this sensor control the radiator fan?......If fan stays on after you turn off ignition?
Thx 🙏
there is no codes but my mazda's temp gauge remains cold even after driving. wonder if this can this solve it.
Useful
where can i found it on my 1.6?
Is this sensor at the water outlet?
Is that the sensor on the water outlet housing?
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
Thanks
Trying to save some money 😂
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
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 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.
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. 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 :)
ALWAYS ALWAYS disconnect the battery before you mess with anything electrical you can damage circuits and sensors and anything like that
Are all sensor the same?
No
I can’t seem to get the connector off
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.
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
What a .otor is that ? 1.8 ,2.0 ,1.6 ?
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
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.
