OBD 2 code is PO174. Check engine light. What is wrong?

bank 2 senses a lean condition. the code sets when long term is above 8% within a set of parameters. look for vaccuum leaks around bank 2, a bad pcv valve, mass air flow or fuel delivery issue. recomend you have a shop track it down and give you a bid as it is not an easy diag unless you find something very obvious.

For your code, you can try: In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect all vacuum and PCV hoses, replace if necessary Check for a dirty fuel filter and proper fuel pressure
