INSPECT ENGINE COOLANT TEMPERATURE SENSOR

Measure the resistance according to the value(s) in the table below.

Standard Resistance

SPECIFIED CONDITION CHART

Condition	Specified Condition
Approximately 20C (68°F)	2.32 to 2.59 kΩ
Approximately 80°C (176°F)	0.310 to 0.326 kΩ

NOTE: When checking the engine coolant temperature sensor in water, keep the terminals dry. After the check, dry the sensor.

If the resistance is not as specified, replace the engine coolant temperature sensor.
