AC off due to high engine temp. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Just looking for any input on this. I have searched several threads and still unclear on the cause. Thanks in advance.

Engine temp is sitting on C. But everything else looks fine, coolant levels look good.

Well I disconnected the ECM harness as someone stated in another thread. That did clear the issue and now my temp gauge and oil pressure gauge are reading correctly. I hope it was just a "glitch" and nothing serious. Still looking for any input if anyone has any ideas. Thanks again

Have you flashed the PCM recently? This is a common problem when using HP Tuners. Remedy is to wait 10-15 minutes after the flash to start the car. I believe it only applies to 2010s though.

i havent. ADM did all of my tuning a few months ago

Hopefully just a glitch then. I have heard of this happening a few times, but never had to deal with it other than when flashing my PCM, and that was an easy fix, so I'm out of ideas. Sorry.

hey, i do appreciate the input! i hope it was just a glitch. I have also read that it could be a coolant temp sensor, or possibly the thermostat.

Happened to me.. Luckily was just low coolant level in the overflow tank on the passenger side of radiator

Got that code on my 08 Silverado one night driving home from work.

Told me A/C was off due to high temp. Which was odd, since the truck was A/C delete.

Spoke with my tuner, and was told that it was just a glitch. So hopefully all is well. Thanks for the input!

Andy got you this far, stay with him.

Did the CEL illuminate? If so, did you pull a code? Was it a P0216 by any chance?
