Check Engine Light --> P0170

[PoorDSMowner]

On my way back from about a 2 hour drive, my car threw a check engine light. I pulled over, listened for any knocking clicking etc...Nothing, running fine.

I got the boys at AutoZone to read it, and it sent me the code P0170 which is my Fuel Trim Bank 1...


Any Ideas on whats wrong, or how to fix it?

Most likely your upstream O2 sensor stopped working. This can be verified through a pocketlogger which lets you view actual values.
