Roll Eyes Temp Gauge Dead w/ SES Light

I was driving today with the AC on and the Service Engine Soon light came on and the temp. gague dropped from it's normal position @ about 3/8 all the way down to 0. The car runs fine and have had no issue with performance since the light came on this afternoon. What would you say is the issue? Coolant sensor, thermostat, instrument panel, blown fuse, or something else?

Thanks!

Default temp guage

From what you described, my guess would be the CTS (coolant temperature sensor). This feeds the temp signal to your guage. Take the car to an autozone (if there's one nearby), they'll scan the SES code for free and tell you what the problem is. If the CTS is the problem it may make your car run poorly, and you may have problems starting it and running in cetain temperature conditions.

Happy

92saturnsl2,

I was also figuring that it was the coolant temp. sensor since performance didnt' seem to be affected too much and the A/C still worked. It's going to be taken into the dealer either tomorrow or Tuesday to read the code and make any repairs (under warranty, of course). Thanks for your response!

Ha! You guys won't believe this one...

The cause of my dead temperature gauge and SES light: RATS! That's right...rats! Somehow, they got up in my engine compartment, chewed all the way through the cable leading to the coolant temperature sensor, and chewed partly though two other wires. Of couse, since "nesting rats chewing through important electrical wires" is not covered under the warranty, we had to pay $185 for a new wiring harness and labor. Oh, well.

Kudos to Saturn of Beechmont for finding the cause of my problem and to alert me to the vermon problem that I have near my car. Only one problem...I don't know if it happened up here @ school or @ home this past weekend.

We see it all the time here,in fact we have a car thats has been in 3-4 times for same problem!The mice always go for the CTS wire or the A/C pressure switch wiring.We finially wrapped the wires in the black plastic conduit to keep them from feeding on the wiring on that car.

Had my check engine light come on a few days ago. Took it to the mechancic and turns out that some mouse chewed through my TPS cable. Set up some traps and poison in my garage today and I am looking forward to turning the place in to one big mouse graveyard.

Depending on where you live it can be a common problem.
I've found that they like the green wires to the A/C pressure switch the most.They also like to fill Air Cleaner boxes with Dogfood.

You should invite them to bite into one of the ignition wires while the car's on. No more rats then!

Holy cow...I never thought a thread dormant for 17 months would come back to life. ;-)
