Component Testing
Static Test
- Ignition OFF, disconnect the harness connector at the Intake Air Temperature Sensor.
- Measure and record the resistance of the Intake Air Temperature Sensor at various ambient temperatures, then compare those measurements to the Temperature Versus Resistance (Engine Coolant Temperature Sensor) table.
- If resistance does not match
Replace the Mass Air Flow/Intake Air Temperature Sensor.
- Go to next step: If resistance matches
- If resistance does not match
- All OK.
NOTE:
A thermometer can be used to test the sensor off the vehicle.
