- INSPECT ENGINE COOLANT TEMPERATURE SENSOR
- Partially immerse the engine coolant temperature sensor in water and warm up the water.
*a Component without harness connected
(Engine Coolant Temperature Sensor)*b Resistance *c Temperature *d Acceptable Range - Measure the resistance according to the value (s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 2.32 to 2.59 kΩ 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, wipe the engine coolant temperature sensor dry.
If the result is not as specified, replace the engine coolant temperature sensor.
- Partially immerse the engine coolant temperature sensor in water and warm up the water.
