P0174 is a dirty air-flow (MAR) sensor. It is located in the inlet air tube near the throttle body. Just clean or replace the sensor. If you want to clean it first, use only electronic cleaner as any other cleaner may damage the sensor. Disconnect the air inlet tube in front of sensor and spray the sensor with electronic cleaner through the screen at the wire element in the center of the sensor. Let it sit a while and spray again. Re-connect the air inlet tube and start engine. If P0174 appears again, you need to replace the sensor.

I have a 2005 mercury Monterey van with a check engine light on. Autozone diagnosed either a mass air flow sensor or O2 sensor problem. I tried cleaning the air flow sensor with air flow sensor cleaner but...


If it is running lean, I'd check correct fuel pressure. Then check for a vacuum leak. 02 sensors are part of a tune-up. I don't like to replace parts unless I'm sure.

I can't rule out a maf sensor.

2001 express p0420 p0174 engine codes , help diagnose !


0174 is system too lean, right bank. 0420 is catalyst sytem efficiency below threshold, left bank. fix would be either oxygen sensor or catalytic converter replacement possibly would need both. note: this veh would possibly have up to 4 oxygen sensors, but cause of problem would be the ones coming off manifolds before the catalytic converter possibly in manifold or y-pipe/down pipe.

Check engine light with codes P0171 & P0174, hesitation at accelleration 2001 mercury sable.


P0171 & P0174 indicate Lean burning on banks 1 and 2. The most common cause is a dirty or defective MAF (Mass Air Flow) sensor. Other causes are bad fuel filters or a broken vacuum line.

There could be many issues. These codes read your engine is running too lean. Check : all your vacuum hoses for leaks, PCV valve and hose, MAF sensor. This may require an experienced technician to figure this out. Hopefully I help'd!!
