Fault text
Valvetronic, thermal overload protection: warning threshold

Fault description
VVT-Overload Protection Control Motor Current Too High

Condition for fault identification
Test condition:
The engine-management system monitors the VVT motor's
current draw. If the monitored current draw exceeds a
defined threshold for several seconds the VVT system is
deactivated (VVT emergency operation mode), and the
engine reverts to throttled operation.
Terminal condition: Terminal 15 ON
Voltage condition:
none

Condition for fault memory entry
always active when DME is awake
current threshold roughly 24A,

Action in service
1. Check for correct reluctor attachment at VVT sensor.
2. Defective VVT servo motor (for instance, interturn short
circuit) Check servo motor and replace as indicated
3. Check wiring harness from VVT motor to DME for shorts
between the two VVT wires and vehicle ground.
4. If abuse is suspected: Clear fault memory from DME
