Coolant Temperature Sensor
Disconnect 4-wire electronic thermoswitch harness connector, located on coolant pipe behind right cylinder head. Measure resistance between ground and terminal "T" at electronic thermoswitch. See Figure. Ensure resistance is as specified with coolant temperature at specified temperature. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If resistance is not as specified, replace electronic thermoswitch.
