Causes, Symptoms, and Repairs of OBDII Diagnostic P0102 Fault

Fault code P0102, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow Circuit Low Input”. This generic powertrain code signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected that the incoming signal voltage from the Mass Air Flow (MAF) sensor is consistently below the minimum expected threshold for the current engine operating conditions .

How to Diagnose and Fix P0103 Fault Code

Fault code P0103, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow A Circuit High Input” or “Mass Airflow (MAF) Circuit High Voltage Input” . This generic powertrain code signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected that the incoming signal voltage from the Mass Air Flow (MAF) sensor is consistently above the maximum expected threshold (typically above 0.46 volts) for the current engine operating conditions .

Causes, Symptoms, and Repairs of OBDII Diagnostic P0106 Fault

Fault code P0106, applicable to all vehicle manufacturers, indicates “Manifold Absolute Pressure (MAP) Sensor Circuit Range/Performance Problem” or “Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem” . This generic powertrain code signifies that the vehicle’s Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected that the signal from the Manifold Absolute Pressure (MAP) sensor is outside the expected or plausible range for the current operating conditions .
