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

Engine Coolant Temperature (ECT) Sensor:

REMOVAL and INSTALLATION
1. Drain engine cooling system.
2. 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 driveablilty and performance.


3. Raise vehicle on hoist.
4. Disconnect engine control sensor wiring from Engine Coolant Temperature (ECT) sensor.
5. Remove ECT sensor.
6. To install, reverse removal procedure. Tighten ECT sensor to 14-19 Nm (10-14 lb ft).
7. Refill engine cooling system.
