Error Code P0101 Causes, Symptoms, and Fixes

Fault code P0101, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow A Circuit Range/Performance” . This generic powertrain code signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected that the signal from the Mass Air Flow (MAF) sensor is outside the expected range or is performing incorrectly .

Error Code P0116 Causes, Symptoms, and Fixes

Fault code P0116, applicable to all vehicle manufacturers, indicates “Engine Coolant Temperature (ECT) Sensor Circuit Range/Performance Problem” . This generic powertrain code signifies that the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected that the signal from the Engine Coolant Temperature (ECT) sensor is outside the expected or plausible range for the current operating conditions .

Symptoms, Causes, Diagnosis, and Repair of P0105 Fault Code

Fault code P0105, applicable to all vehicle manufacturers, indicates “Manifold Absolute Pressure (MAP) Sensor Circuit Malfunction” or “MAP Sensor Circuit Insufficient Activity” . This generic powertrain code signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected a problem with the signal from the Manifold Absolute Pressure (MAP) sensor, where the sensor’s output is outside the expected range or shows insufficient activity .
