This is indicating a small vacuum leak. Probably a cracked/broken vacuum hose under the engine cover. Get a good flashlight and start checking around. Let me know what you find.

I was driving my 2007 acura rdx when I noticed the sh-awd light on. I then saw the check engine light on. Later when I turned my car on again the check engine light was still on, not the sh-awd light. ...


The SH AWD uses electromagnetic clutch in the back drive axle to change the power distribution to the rear wheels. It would have nothing to do with the P0171 error. What TPMS valve stem was bad? Because this could be a clue to what the problem is. If a rear tire is having issues it could cause the sensor to make adjustments to the system to compensate for the tire. The person that changed the TPMS might have also caused the issue when they worked on the tires.

Ford windstar check engine light comes on after stopping when starting to get moving again shows p0171 & p0174 codes why??


P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Thanks.
