The coolant temperature information is conveyed to the instrument panel, through the PCM, from the Engine Coolant Temperature (ECT) sensor. To test and remove the sensor, refer to Driveability & Emissions Controls . To test the gauge, perform the following testing procedure.
Cirrus, Stratus, Sebring Convertible and Breeze
- Initiate the instrument cluster self-diagnostics by pressing the odometer/trip reset button while turning the ignition key through the OFF/RUN/START positions. This will cycle an electronic display segment check and illumination of all the instrument cluster warning indicators and gauges.
- If all of the gauges fail to move, replace the instrument cluster circuit board.
- If any separate gauge fails to move, replace that gauge.
- If any gauge is not positioned properly, replace the printed circuit board
Sebring Coupe and Avenger
See Figure 1
- Detach the coolant temperature sensor electrical connector.
- Connect a 12 volt test light between the harness side connector and ground.
- Turn the ignition switch to the ON position. The temperature gauge should be at its lowest position.
- Replace the coolant temperature gauge if the test light illuminates but the gauge needle does not move.
- If the test light illuminates and the gauge needle moves, replace the coolant temperature sensor.
- If the test light does not illuminate and the gauge needle does not move repair the wiring harness.
