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.
