Thread: Driving with the ECT Sensor Disconnected

Yea that what I thought, I read up on it & I didn't know this sensor control everything because if it shows no tempature everything wont run right.

Well I looked at the ECT Sensor to try to see if I could connect it, but It looked like the black cover was missing off the tip of the sensor & all I saw was 3 long prongs. So I said F*ck it, I didn't wanna short the PCM out until it was time for me to upgrade it. The mechanic was a great guy & had cheap prices (He's also an ex GTP tuner), but IMO I think he probably broke it when he was replacing the LIM Gaskets. He said he would replace it for $40 total with the sensor, but he like an hour from me & I dont have the time to go out that far.



Can anybody give me instruction on how to replace this sensor myself, I would great appreciate it

If he just got done doing the LIM gaskets, then yes, I would say he broke it. It is not necessary to take the sensor out to change the gaskets. But if you are not careful when you remove the LIM, you can easily break the sensor. So I would put my money on him breaking it.

But changing it is very easy. Buy the sensor. Put a little thread sealant on the new sensor. Remove the old one. Put in the new one quick. You shouldn't loose too much coolant, but check it and fill if necessary after a couple days.

Ok I just bought the sensor today. I see where the old sensor is, but it looks to be in a cramped spot at a wierd angle. Zef do you know the quickest & easiest way to get to the sensor & what tools to use.
