Question
- Are the measurement values OK?
YES
The measurement values are OK.End of test
NO
The measurement values are not OK.Possible cause and remedy
- B11/4 (Coolant temperature sensor)
End of test
2032
The value of component B2/5b1 (Intake air temperature sensor) does not change. (P0111)
Possible cause:
- B11/4 (Coolant temperature sensor)
- B2/5 (Hot film mass air flow sensor)
Affected functions:
- Engine diagnosis
-------------------------------------------------
