so my temp guage doesnt really show and reading. Ive had this truck for 5 years now and it seemed like it worked so i left it alone..i was gone for over a year and now i want to check it out..the wife was driving it and from what she said it might of over heated. How do i check to see if the temp guage is working.
I thought about using a voltage meter and check that way...but where do i start..in the console its self or in the fuse box?

Thanks

The Factory Service Manual has a test procedure in the "Body Electrical" (BE) section.

My Check engine light came on today, Got 4 flashers..i checked the code online and said something about the ECT. Coolant Temp. Where do i start to solve this problem.
My temp gauge still doesn't move like a regular temp gauge. I drove for 35 miles and the temp gauge said it was still cold. Thnx in advance fellas

OK, I was about to post the same question but did the search first and found this. If the gauge is good with grounding the wire and it went to HOT could it be the sending unit? Checking the unit would be a check with ohm meter for resistance? My Cat is bad and tailpipe is black with rich smell so this could fix it. Thanks.

Yep, sender is a variable resistance device. I think the FSM lists some resistance vs. temperature values.

Okay so i grounded the Temp Sensor and the gauge did not move at all, when it is not grounded it moves like 3mm

I pulled the wire off, Grounded that Wire, turned the ign on and the gauge does not move at all, I did this while the truck was hot.
