Must be a sensor??	Sign In

I have a 2009 Chevy Cargo Van, v-6 engine. 115,000 miles currently. Runs like a champ!!
Recently I have been having a OBD message coming up that states the engine is running hot, and that it is turning off a/c. When this happens, the temp needle actually drops to cold, and does not function. The engine is not over heating, and it still will come up even after the van has set over night. It only seemed to happen when using Defrost at first, now its doing it in standard, and getting worse. Any thoughts on if this is a sensor going bad? if so, what one, and is it something I can change my self?

How is the coolant level? Are there any trouble codes being stored? If so, can you post the numbers in here?

Had OBD checked at first sign, nothing was saving, coolant levels have been fine. Just had oil change, level was not even low. I will see if they can check OBD again, and let you know.

Thank you!

If they have a high end scan tool that can look at engine computer datastream information, have them monitor the ECT voltage or temperature when the problem is occurring.
