Sensor Inspection

Intake Air Temperature Sensor Inspection:

1. Disconnect the intake air temperature sensor connectors.

2. Measure resistance between terminals (1) and (2).

Temperature [°C (°F)] Resistance (K ohms)

0 (32) 6.0
20 (68) 2.6
80 (176) 0.3

3. Remove intake air temperature sensor from intake manifold.

Intake Air Temperature Sensor Inspection:

4. Measure resistance while heating the sensor using a hair drier.

Temperature Resistance

Higher Smaller

5. If resistance does not decrease as heat increase or the resistance remains unchanged replace the intake air temperature sensor.
