Coolant Temperature Sensor
Warm engine to normal operating temperature and stop engine. Using a thermometer, measure temperature of coolant. Disconnect electrical connector from temperature sensor and connect one lead of ohmmeter to terminal in sensor and other lead to ground. Ohmmeter readings should be as specified in table. If not, replace temperature sensor.
TEMPERATURE/RESISTANCE RELATIONSHIP
