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

Possible fault causes
- Corrosion or loose contact of signal line
- Corrosion or loose contact in power supply (naturally aspirated)
- Corrosion or loose contact in ground supply (Turbo)
- Intake air temperature sensor faulty

- Only naturally-aspirated engines:
- Affected contacts on the DME control unit connector:
- Connector [A] contact 27
- Affected contacts on the hot-film mass air flow sensor 1 connector:
- Contact 1
- Contact 2

- Turbo only:
- Affected contacts on the DME control unit connector:
- Connector [B] contact 41
- Affected contacts on the boost pressure sensor connector:
- Contact 2
- Contact 1
