DTC P0103: MAF Sensor Circuit High Input: Condition

DTC is set when Powertrain Control Module (PCM) detects input voltage from Mass Airflow (MAF) sensor is less than 4.89 volts 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.
• Open circuit between PCM and MAF sensor.
• Open circuit between ground and MAF sensor.
