Temperature Sensor (Gauge): Description and Operation
Temperature Gauge
The PCM receives the engine coolant temperature status through hardwired circuitry to the engine coolant temperature (ECT) sensor. The instrument
cluster receives the engine coolant temperature data from the PCM through the SCP communication network. The instrument cluster microprocessor
monitors the engine coolant temperature data received from the PCM and commands the temperature gauge indication with a corresponding movement
of the pointer.
