Component Testing

Static Test

1. Ignition off, remove the engine coolant temperature sensor.
NOTE: A thermometer can be used to test the sensor off vehicle.
2. 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 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.
