Code P0118??

[jordan01GTS]

I have found that the code P0118 is "Engine Coolant Temperature Circuit High Input" So what do I do, I try to erase the code and it comes back on as soon as I start it up again. Does anyone no what wires to trace, or ways to test circuit?

More than likely the coolant sensor. I can copy my diagnostic manual service pages if you need them.

I forgot to add that I changed the sensor already because my gauge isnt reading a temp, still doesnt even after I changed the sensor, the gauge may be to blame for that though.

The other items mentioned in the 2001 diagnostic manual are PCM or wiring issues. Has your car ever had wiring problems?

 

[jordan01GTS]

yes it has, i just had a injector wire problem. I would like to find out what to test and where to test so I can narrow this down.

Anyone?

I was reading some other posts and I was wondering if its normal for the fan to immediately come on when I start a cold engine? maybe this is a result of whatever is wrong.

Fan coming on would mean that the temp sensor input says above 180F (or whatever the ECU is set for.

You need a shop manual so that you can trace the wiring. Check the voltage at the guage. Perhaps you have a short (maybe in the guage)?

Does your engine have the proper ground strap?

 

[jordan01GTS]

Where is the ground strap located? I dont recall seeing one.

Well I finally got back to looking into the problem and it was all caused by the the signal ground on the harness was not making contact to the sensor, What a pain I went through to find this was the problem. Caused the CEL, Gauge not working, and fans running. I realy appreciate all the help. She runs great now.

She runs great now.

Maybe it's a he
