Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information
Condition
The central electronic module (CEM) transmits the signal from the outside temperature sensor via CAN to the engine control module (ECM).
The diagnostic trouble code (DTC) is stored in the engine control module (ECM) if the central electronic module (CEM) has determined that the signal from the outside temperature sensor is incorrect.
The fault is diagnosed at ignition on or with the engine running.
Substitute value
Value from the engine intake air temperature (IAT) sensor in the intake manifold is used.
Possible source
- Fault-trace the central electronic module (CEM).
Fault symptom[s]
- Starting/Engine hard to start/cranks slowly/Unsure when/at all times
- Gauges/Ambient temperature gauge not accurate/does not work
