Thread: Coolant Temperature Sensor

Heh, yeah, both give the same readings. But, you are right, OBDII is blue plug and OBDI is red. Connections are different shapes. Sensors themselves are the same.

Well I asked because the temp reading on the ECU is quite a bit different than the gauge reading, and in some cases varies as much as 40 degrees. For instance, whn I first start the car in the morning, the coolant temp reads 60 degrees when it's below freezing outside

the gauge to ecu difference is nominal at operating temps. I don't trust the obdII sensor.

Mine is exactly the same

Do me a favor, if you replace the OBDII sensor, can you test the OBDI in a pot of water at various temps, and then the OBDII and record the resistances?

I'll test them if I can get around to it I've got to drop my tranny today and replace it with a P11 LSD unit

WINGMAN UPDATE

wire has been soder'd end of wire where it goes to connecter is from factory as well

we will now see

nothing wingman

while i had the soder out i decided to hit up the vvl solenoids and remove the ghetto rigg i had on there before and it works fine now..

temp still stays low as hell

we should just make a low winter temp club lol.. i just think its the ve's nature to run cool.. i've come to live with it, however the other day i did see the needle creep to about half way to the middle line, stuck in traffic.. as soon as i started movin it was back down tho.. ALSO had to bump my idle valve thing up a bit because she kept tryin to die at lights, idles still right on the money but no tryin to die on me lol

what's low as hell? can you give me a degree reading?

ok if you look at the temp gauge in the dash, the VERY first white line is bout as far as mine usualy goes, an i bet doughnuts that his is the same way.. isnt there a way to check in the consult tho to see the exact temp?
