Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P010200

Condition




The engine control module (ECM) continuously monitors the mass air flow sensor signal for plausibility and checks that it is consistent with the mass air flow sensor characteristics.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The signal is outside its normal range.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.

Substitute value
- Calculated air mass
- Rear heated oxygen sensor (HO2S) control shut off
- Misfire diagnostic shut off.

Possible source
- Open-circuit in the signal cable
- Open-circuit in the power supply
- Short-circuit to ground in the signal cable
- Contact resistance in the mass air flow (MAF) sensor connectors
- Damaged mass air flow (MAF) sensor.

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