Diagnostic Trouble Code (DTC) Information






Diagnostic trouble code (DTC) information

Condition




The engine control module (ECM) checks the signal from the outside temperature sensor in the left door mirror. The diagnostic trouble code is generated if the control module detects that the value for outside temperature deviates too much from the intake temperature, fuel temperature or coolant temperature after the engine has been warmed up and then allowed to cool for at least 8 hours.
The diagnostic trouble code can be diagnosed once per operating cycle with the ignition on, but only once the engine temperature has fallen to approx. 50 °C from operating temperature since the previous operating cycle.

Substitute value
- If the air temperature (measured in the mass air flow (MAF) sensor) is fine, use this temperature in place of the outdoor temperature, otherwise a constant 20 °C is used.

Possible source
- Contact resistance in connector.
- Damaged outside temperature sensor.

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