Fault description

VVT-Value Comparison Starting Position/Parking Position

Plausibility (Bank 1)

Condition for fault identification

Test condition:

When the DME is activated (wake-up) it assesses the current

VVT sensor angle based on the last VVT sensor angle prior

to shutdown. If there is a substantial difference in the two

204

angles, the operative assumption will that substantial repairs

have been carried out on the cylinder head. The VVT travel

limit positions must be re-initialized.

No VVT sensor faults should be present (#10800,

#10801,#10802).

Terminal condition: Terminal 15 ON

Voltage condition:

none

Condition for fault memory entry

Following successful travel limit initialization routine (can

be initiated by tester),

active only once at moment when system starts (DME wakeup).

Action in service

Conduct travel limit initialization routine using tester for

activation. Delete stored fault codes from DME fault

memory and initiate dormant vehicle state. Repeat procedure

in case of doubt.
