Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P010100

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 low.
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 ground.
- Open-circuit in the signal cable.
- Damaged mass air flow sensor.

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