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

Standard Resistance

Tester Connection	Condition	Specified Condition
1 - 2	Approx. 20°C (68°F)	2.32 k to 2.59 kΩ
1 - 2	Approx. 80°C (176°F)	0.310 k to 0.326 kΩ

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

NOTE:

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

HINT:

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