Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection

INSPECT E.F.I. ENGINE COOLANT TEMPERATURE SENSOR




Check the resistance.

1. Using an ohmmeter, measure the resistance between the terminals.




Standard:

NOTE: If checking the engine coolant temperature sensor in water, be careful not to allow water to intrude into the terminals. After checking, wipe up water on the engine coolant temperature sensor. If the result is not as specified, replace the engine coolant temperature sensor.
