DTC P0102: MAF Sensor Circuit Low Input: Condition

DTC is set when Powertrain Control Module (PCM) detects input voltage from Mass Airflow (MAF) sensor is less than .36 volt with engine running. This is a continuous monitor. MIL is illuminated when PCM detects malfunction during 2 consecutive drive cycles. Possible causes are:

• MAF sensor malfunction.
• Short or open circuit between PCM and MAF sensor.
• Open circuit between main relay and MAF sensor.
