- Turn ignition switch OFF.
- Disconnect engine coolant temperature sensor harness connector.
- Remove engine coolant temperature sensor. Refer to "EXPLODED VIEW ".
- Check resistance between engine coolant temperature sensor terminals by heating with hot water as shown in the figure.
Terminals Condition Resistance 1 and 2 Temperature [°C (°F)] 20 (68) 2.37 - 2.63 kΩ 50 (122) 0.68 - 1.00 kΩ 90 (194) 0.236 - 0.260 kΩ Is the inspection result normal?
YES: INSPECTION END
NO: Replace engine coolant temperature sensor. Refer to "EXPLODED VIEW ".
