Diagnostic Trouble Code (DTC) Information

ECM-P010300 Air Mass or Volume, Airflow Circuit High Input Signal

Condition







The engine control module (ECM) measures the air mass through the intake manifold using a sensor.

The diagnostic trouble code (DTC) is stored if the Engine Control Module (ECM) detects that the signal from the mass air flow (MAF) sensor is too high.

The diagnostic trouble code can be diagnosed when the ignition is on.

Substitute Value
- A value calculated from factors such as engine speed and air pressure in the intake manifold is used.

Possible Source
- The signal cable is short-circuited to voltage.
- Damaged mass air flow sensor.

Fault Symptom[s]
- Malfunction indicator lamp (MIL) lit.
