P0102 Mass or Volume Air Flow A Circuit Low
Description The mass air flow (MAF) sensor circuit is monitored by the powertrain control module (PCM) for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key on, engine running (KOER) the air flow (or voltage) changes below a minimum calibrated limit, the test fails.
Possible CausesMAF 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

Diagnostic AidsA MAF V PID reading less than 0.23 volt in continuous memory or KOER indicates a hard fault.

P0103 Mass or Volume Air Flow A Circuit High
DescriptionThe mass air flow (MAF) sensor circuit is monitored by the powertrain control module (PCM) for high air flow (or voltage) input through the comprehensive component monitor (CCM). If during key on, engine off (KOEO), or key on, engine running (KOER), the air flow (or voltage) changes above a maximum calibrated limit, the test fails.
Possible CausesMAF sensor screen is blocked
MAF circuit shorted to voltage
Damaged MAF sensor

Diagnostic AidsA MAF V PID (MAF PID) reading greater than 4.6 volts during KOER indicates a hard fault
