RADIATOR COOLANT TEMPERATURE SENSOR
1. Check resistance between radiator coolant temperature sensor terminals 1 and 2 as shown in the figure.
CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use
a ground other than ECM terminals, such as the ground.
2. If NG, replace radiator coolant temperature sensor.
