Diagnostic Trouble Code (DTC) Information

ECM-P011100 Intake Air Temperature Sensor 1 Circuit Within/Exceeding Limit Values

Condition







The engine control module (ECM) checks the signal from the air temperature sensor in the intake manifold.

The diagnostic trouble code is generated if the control module detects that the value from the air temperature sensor deviates too much from the value of the engine temperature sensor after the engine has been switched off for a period of time.

The diagnostic trouble code can be diagnosed once per operating cycle with the ignition on, but only once engine temperature has fallen to approx. 55 degree C from operating temperature since the previous operating cycle.

Substitute Value
- The intake temperature value is set to 30 degree C.

Possible Source
- Contact resistance in connector.
- Damaged air temperature sensor (integrated in mass air flow sensor).

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