Air Temperature Sensor ( Ambient / Intake ): Testing and Inspection

Engine Coolant, Intake Air, And Transmission Temperature Sensor Specifications:





1. Disconnect the wire harness connector from the intake manifold temperature sensor.
2. Test the resistance of the sensor with a digital volt-ohmmeter. The measured resistance should be less than 1340 ohms with the engine warm. Refer to the above sensor resistance chart for exact values.
3. Replace sensor if it is not within the range of resistance specified in the chart.
4. Test the resistance of the wire harness. Check between the Powertrain Control Module (PCM) terminal 21 and the appropriate sensor connector terminal. Also check between PCM 4 and the appropriate sensor terminal. Repair the wire harness if the resistance is greater than 1 ohm.
