Diagnostic Trouble Code (DTC) Information

ECM-P011300 Intake Air Temperature Sensor 1 Circuit High Input Signal


Condition







The engine control module (ECM) measures the temperature of intake air using a temperature sensor in the intake manifold (integrated in the mass air flow sensor).

The diagnostic trouble code (DTC) is stored if the Engine Control Module (ECM) detects that the signal from the intake air temperature (IAT) sensor in the intake manifold is too high.

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

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

Possible Source
- The signal cable is short-circuited to supply voltage.
- Open-circuit in the signal cable.
- Damaged air temperature sensor (integrated in mass air flow sensor).

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