- Test the ambient temperature sensor by observing the temperature sensor while also monitoring the sensor resistance.
- Compare the readings with the temperature versus resistance table, verify that the resistance is within 5 percent of the specification.
- If the resistance versus temperature reading is not within the specified range, replace the ambient air temperature sensor.
