Hey guys sorry to bring this outta nowhere. But it seems like this might fall in my area.
Im getting a cel (p0125) for closed loop temp not reached. Would my temp sensor cause this? (the little flat pin one)
I just replaced the sensor to turn the fan on cause it was not coming on. Also I was having a problem with the idle (around 2000) when I first start it its at 900 then goes up to previous said. It gets higher when I minus air off afc. I idle adj. screw is al the way out how can I fix that? Thanks

The single pin connector is for your dash gauge, the double pin is for your ecu. The CEL is probably because of the double pin connector... I just priced one at NAPA and it was $11...

Yeah I just replaced that one though like I said, I checked what it could be it says either, stuck thermostat, low coolant level, bad temp sensor. So i'm gonna try the other two after work.

hey im having some similar problems. Temp guage seems stuck? at like almost 3/4 of the way. On my way home from the movies i noticed it was a little high, since it normally hangs around 1/2, and since then ive came home and it hasnt gone down at all. When i unlpug the bigger plug on the back of the t-stat housing my fans come on, but didnt come on earlier when the car was hot? Hoses seem hot, but almost not as pressurized as normal. What do you guys think?

well the more i read about it maybe its just the guage sensor and the rest is just in my head.

I think: thermostat in upside down, bad radiator cap, or bad thermostat.

Well i tested the guage by grounding it out and it went all the way past hot like it should, i then plugged it back up and started the car and the guage was down at cold where it should be. I drove it around a bit now and all seems fine, so not sure what was up with it to get stuck like that. I do have a CEL that i will get scanned because i just thought it was me not having my rear o2 in my exhaust, but now with this mess i guess it could be the ECU temp sensor. I also was a bit low on antifreeze and so i filled it up and now the pressure on the hoses seems back to normal. Guess i will just keep a watch on it and get the code scanned and see what happens.

My wires got old and ripped out of the coolant temp plug. How can i fix this or where can i find a new plug?

Looks like my coolant temp sensor went out and I never knew that would make it hard to start the car. Going to pick up a new one within the next couple of days so hopefully the starting issue will go away and the CEL was on throwing the coolant temp sensor code.

Ive been reading and people say they have had a hard time getting the correct sensor. Why is that? Hearing this makes me want to just pay the $60 from the dealership. Got me nervous from ordering online or at a parts store.

Sorry if this seems like a stupid question, but in the photo above I couldn't help but notice you do not have a CAS where I have one in my 1g...explanation?

The '97's have the cam angle sensor back on the passenger side of the head.

most likely its the Coolant temperature sensor, mine went out and what has been described seems to be the issue. replace the following if you havn't already since getting the car:

thermostat-$15
ECT-1 pin-left side of thermostat inlet pipe.$15
Coolant sensor-thermostat housing-2pin connection$20
radiator cap-special release valve is what i prefer-$8

the reason for this is because the coolant system is a pain in the ass, make sure everything is running as smooth as you can. After fixing all of these in my car it ran awesome again, a total of $60
