Question

1998 Ford F150 4.6L with engine code P0102. Installed new plugs and wires, cleaned Mass air, replaced air filter, and checked intake manifold for leaks. Pickup is idling rough, with no power, and stalls, what do I look for next?

Answer 1

Hi there,

With the P0102 showing, you need to check for power to the sensor as well as the sensor may be burned inside. Cleaning it isn't going to help if the sensor wire itself has burned up and lost the connection. Take a test light and check to see if you have power with the key on, if you do replace the maf sensor.

Answer 2

P0102 Ford Code - Mass Or Volume Air Flow Sensor 'A' Circuit Low Input
