Component Testing

  1. Ignition OFF, disconnect the harness connector of the IAT sensor.
    2. IMPORTANT: A thermometer can be used to test the sensor off the vehicle.
  2. Test the ECT sensor by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature Versus Resistance - Intake Air Temperature Sensor table and verify that the resistance is within 5 percent of the specification.
    • If the resistance vs temperature is not within 5 percent, replace the ECT sensor.
