Diagnosis information - DME V8 DFI
Intake air temperature sensor: electrical fault
NOTE:
In the case of the Turbo engine, the intake air temperature sensor is integrated in the boost pressure sensor.
In the case of the naturally-aspirated engine, the intake air temperature sensor is integrated in the hot film mass air flow meter 1 (right).
NOTE:
- Only naturally-aspirated engines:
Cross-exchange is possible because both hot-film mass air flow sensors including tubular piece are identical, but the intake air temperature
sensor is used only on the right.
NOTE: The hot-film mass air flow sensor must not be removed, but only interchanged complete with tubular piece.
Diagnostic conditions
- Vehicle voltage > 9 V
- Ignition on > 5 seconds
