3. Installed condition of intake air temperature sensor.
• Check for looseness or pinching.
Refer to “GENERAL CHASSIS (2)” on page 4-10.
4. Defective intake air temperature sensor.
• Check the intake air temperature sensor.
Refer to “CHECKING THE INTAKE AIR TEMPERATURE SENSOR” on page 8-64.
5. Defective wire harness.
• Replace the wire harness.
• Execute the diagnostic mode. (Code 05)
• Submerge the intake air temperature sensor in a container of 0 °C (32 °F) water.
• The displayed temperature is close to the 0 °C (32 °F)
Is check result OK?
YES
→ Go to step 4.
NO
a. Reinstall the sensor.
b. Execute the diagnostic mode. (Code 05)
• When engine is cold: Displayed temperature is close to the ambient temperature.
Is check result OK?
YES
→ Go to step 7, and complete the service.
NO
→ Go to step 4.
