Question about 1998 Chevrolet K3500
I have a problem with my truck...... The mass air flow sensor is not reading anything. I have replaced it and hooked it to a machine that still shows a code P0102...... While the same computer was attached I clicked on the gauges to see what they were reading and the mass air flow sensor was not even registering a reading.... What can cuuse this??
Most likly you have an open short, a wire that has been broken. also make sure you don't have any corrosion on the plug this will cuase you to get no reading in the data stream. The only other thing i can think of is a bad PCM because you have nothing between teh 2 componants.
I would find the wire lead at the pcm and unplug it and do a continuity test on the wire to make sure its good.
