Vehicle make/model = 2001 pontiac grand am
Mileage = 76k
Engine size = 3.4
dash lights = check engine light
codes = lean
work done to repair = none yet.
tip/donation yes
tech = jk
question = My grand am has a check engine light on. I had the codes
pulled from a scaner at autozone. They said it was p0171 and i need an oxygen sensor.
Do you think this right? How do i replace it. where exactly is it. Thank you very much.
JK:
Thank you for the tip/donation. It is possible that the oxygen sensor is bad. First you
should check for a vacuum leak. Some common areas of vacuum leaks on that engine
are the pcv hose, evaporative system purge solenoid valve, or upper intake manifold
gaskets. A loose air intake duct can also cause this. If there are no vacuum leaks
found, then yes, it does sound like a bad oxygen sensor.
Thanks again for tip/donation.I will send some pics of these areas to check for vacuum
leaks, and location of the oxygen sensor this code refers to.
