Test C: Incorrect Temperature Gauge Indication

PINPOINT TEST C: INCORRECT TEMPERATURE GAUGE INDICATION

C1-C4:

Normal Operation
The powertrain control module (PCM) receives the engine coolant temperature status through hardwired circuitry and the cylinder head temperature sensor. The instrument cluster receives the engine coolant temperature data from the PCM over the controller area network (CAN). The instrument cluster monitors the engine coolant temperature data received from the PCM and commands the engine coolant temperature gauge pointer.

Possible Causes
- PCM
- Instrument cluster
