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. Diagnosing drivability issues is a process of elimination. Compare your vehicle's components with known-good signals for accurate diagnosis and quick repair. Check out all the sensors available on NAPAonline or trust one of our 17,000 NAPA Auto Care locations for routine maintenance and repairs.
