Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
Component Testing
Checking The Coolant Temperature Sensor Resistance
1. Remove the engine Coolant Temperature Sensor from the intake manifold.
2. Using alligator clips, connect an ohmmeter to the sensor terminals.
3. Immerse the sensing element in hot water, being careful not to set the housing in the water. This would alter the resistance reading.
4. Resistance should decrease, as the temperature increases. Refer to SPECIFICATIONS/ELECTRICAL.
If the resistance deviates from the standard value, replace the sensor.
