Inspection Component
- Remove the Engine Coolant Temperature Sensor (ECTS).
(Refer to " REMOVAL ")
- After immersing the thermistor of the sensor into engine coolant, measure resistance between ECTS signal terminal and ground terminal.
- Compare the measured resistance with the specification to below.
