P0210 code with a/c wtf?
 

It's been real hot where I live lately. The other day I left the wife in the car with the a/c on full blast for a couple of minuets and when I came back my CEL was on. I went to get the code pulled and got P0121 (throttle/peddle position sensor). Got in the car the next day and the light was off. Drove it for approximately 30 miles then parked with the a/c on for a few minuets and got another CEL. Has anyone had a similar problem with the a/c on or with P0121? Are they at all related? Thanks in advance

Good morning tahoe,

Are you planning on working with your dealership to get this checked out? Keep us posted if so as we're available to help as much as we can. If you want for us to check into warranty or recall information for you, please provide the last 8 digits of your VIN and we'd be happy to do that!

TPS signal sensor, voltage out of range. Not related to a/c. It is probably the tps.

Is there a way to resolve that potential issue?

The pcm sends a voltage signal out to it, reads what comes back. This is out of range according to my book. I'd say probably the sensor is the issue.
