Fault text
Valvetronic servomotor, position sensors: Supply voltage
faulty

Fault description
The diagnostic function monitors the power-supply wires to
the position sensors.

Condition for fault identification
Test condition:
The fault is recognized when the DME hardware detects a
fault in the voltage supply to the Hall-effect sensors.
Potential problem source(s):
- Defective wiring harness
- Valvetronic actuator defective
- Defective DME
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- none

Condition for fault memory entry
none

Action in service
- Check wiring harness between Valvetronic actuator motor
and DME
- Check Valvetronic actuator motor
Check Valvetronic actuator motor with multimeter,
specified results:
Pin 11 to Pin 10: roughly 1 mOhm
Pin 11 to cylinder head: Infinite resistance
Pin 10 to cylinder head: Infinite resistance
- Replace Valvetronic actuator motor
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
The engine runs in throttled mode, full drivability/power
Possible apparent symptoms:
VVT reverts to limp-home mode, minor effects can be felt
