Coolant Temperature Sensor/Switch (For Computer): Service and Repair

Engine Coolant Temperature Sensor:

REMOVAL
1. Disconnect battery ground cable.

NOTE: When battery voltage is removed from the Powertrain Control Module (PCM), all learned values will be cleared and reset to predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.

2. Partially drain cooling system.
3. Disconnect Engine Coolant Temperature (ECT) sensor electrical connector.
4. Remove ECT sensor from lower intake manifold.

INSTALLATION
1. To install, reverse the removal procedure.
2. Tighten the ECT sensor to 16-24 Nm (12-17 lb ft).
3. Refill cooling system.
