Yes, clear the codes and read them again if the light comes back on. We will assume the battery/charging system is in proper condition.
P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON, engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to the MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near the MAF sensor)
A closed throttle indication (throttle position [TP] sensor system)
Damaged MAF sensor
Damaged PCM
DC4 KOER AND CONTINUOUS MEMORY DTCS P0102, P0104 OR P1101: CHECK THE INTAKE AIR SYSTEM FOR LEAKS, OBSTRUCTIONS AND DAMAGE
CHECK the air inlet system (air cleaner, housing, ductwork) for obstructions or blockage.
CHECK for broken/loose air outlet tube clamps (throttle body and air cleaner assembly ends), cracks/holes in the air outlet tube, and worn gaskets between the MAF sensor and the air cleaner assembly. Verify the MAF sensor is connected. Repair as necessary.
Were there any concerns found during the visual inspection?
