Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection

CIRCUIT DIAGRAM






USING HI-SCAN






USING MULTI-METER

1. Remove engine coolant temperature sensor from the intake manifold.





2. With temperature sensing portion of engine coolant temperature sensor immersed in hot engine coolant, check resistance.
3. If the resistance deviates from the standard value greatly, replace the sensor.








HARNESS INSPECTION


INSTALLATION
1. Apply sealant LOCTITE 962T or equivalent to threaded portion.
2. Install engine coolant temperature sensor and tighten it to specified torque.

Tightening torque
Engine coolant temperature sensor 20-40 Nm (200-400 kg.cm, 14-29 lb.ft)

3. Securely connect the harness connector.
