2002 Buick Park Avenue 6 cyl Front Wheel Drive Automatic 100K miles
I have a Mass Air Flow Alarm Code. I suspect the sensor itself is bad. It should probably be replaced. I am not a fan of swapping out $150 parts as a form of troubleshooting.
Do you know if Mass Air Flow Sensors are outputing a range 0-10 volts (analog) or (discrete) 12v on/12v off. If it is a discrete normally open sensor I can add a jumper wire to bypass sensor to rule out any other causes.
have the same problem?
