[8] Monitoring of air temperature sensors: The difference between the intake air temperature and another air temperature is too great.

Test 1: Check actual value Intake air temperature. Plausibility

1. Check actual value Intake air temperature. Plausibility
Test prerequisite

- Engine at idle
Status of the relevant actual values:
- Intake air temperature Left:Warning! Communication with ECU required.

- Intake air temperature Right:Warning! Communication with ECU required.

- Boost air temperature:Warning! Communication with ECU required.
Specified value

- The actual values must be plausible.
- Temperature range: -10° C to 80° C
Question

- Are the actual values o.k.?


YES
The actual values are okay.Further procedure

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..
End of test

NO
The actual values are not plausible.Possible cause and remedy

- Replace component if its value is implausible.
End of test
