Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello and thank you for your question,One common cause for this code to set can be caused by a dirty MAF (mass air flow ) sensor or even a failed MAF if it got wet when you hit the ditch. I would start first with making sure the intake hose from the MAF to the throttle body is porperly installed and not leaking and if that looks okay the try disconnecting the negative battery cable and take some MAF cleaner and give the MAF a good cleaning.After doing so reconnect the battery and see if the code retrurns.
Did you try cleaning the MAF as I suggested?
So you saying the filter is missing?
Well I think you just found your problem, it need to be replaced and I would also clean the MAF as I suggested.
