Component Testing
Static Test
- Ignition off, remove the B34 engine coolant temperature sensor.
- Test the B34 engine coolant temperature sensor by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature Versus Resistance - Engine Coolant Temperature Sensor
Temperature Versus Resistance table and verify that the resistance is within 5% of the specification.
- If not within the specified range, replace the B34 engine coolant temperature sensor.
NOTE:
A thermometer can be used to test the sensor off vehicle.
