INSPECTION USING SCAN TOOL





HARNESS INSPECTION PROCEDURE

COMPONENT TEST PROCEDURE
1. Remove engine coolant temperature sensor from the intake manifold.








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

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

Torque: 20 - 40 Nm (14 - 29 lb.ft)

3. Securely connect the harness connector.

TROUBLESHOOTING HINTS
If the fast idle speed is not enough or the engine gives off dark smoke during the engine warm-up operation, the engine coolant temperature sensor might be the cause.
