Partially soak the sensor in the water and warm up the water.

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

Standard Resistance

Tester Connection	Condition	Specified Condition
1 - 2	Approximately. 20°C (68°F)	2.35 to 2.65 kΩ
1 - 2	Approximately. 80°C (176°F)	0.305 to 0.331 kΩ

NOTE:

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

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