How would i go about diagnosing this code. The car has under 50k on it so i doubt it has a dirty tb iac valve or pcv valve, although i have not visually checked to confirm any of this and it runs good enough to where i doubt it has any vacume leaks.

 

have you done anything recently that could have caused this to happen ?

have you cleaned the throttle body recently ?

 

I just bought the car, and i havent done any work on it yet. i know the dealer detailed it before i drove away and the code wasnt on when i test drove it. it also has an aftermarket maf sensor on it, could that possibly be causing the code?
