Diagnostic Trouble Code (DTC) Information ECM-P011126: Notes
Condition
The engine control module (ECM) checks the signal from the temperature sensor in the intake manifold under two different driving conditions. The check is first made during high airflow while the vehicle is travelling and then while the vehicle is stationary and idling. The diagnostic trouble code is generated if the control module registers that the temperature difference between these two measurements is unreasonably similar.
Substitute Value
- The value for the inlet temperature is generated to equal to the value for the fuel temperature.
Possible Source
- Contact resistance in connector.
- Damaged air temperature sensor (integrated in mass air flow sensor).
Fault symptom[s]
- Malfunction indicator lamp (MIL) lit.
