Temperature Sensor (Gauge): Testing and Inspection
1. Disconnect the YEL/GRN wire from the coolant temperature sending unit.
2. Using an ohmmeter, measure the change in resistance between the positive terminal and the engine (ground) with the engine cold and with the
engine at operating temperature.
3. If the readings are substantially different from the specifications above, inspect the coolant level and the cooling system. If the cooling system is
OK, replace the sending unit.
