VVT-Self-Learning Function Faulty Adjustment Range

(Bank 1)

Condition for fault identification

Test condition:

Adjustment range monitor When travel limit initialization

routine is executed. (travel limit initialization routine is

automatically executed in a 5 hour (engine operating hours)

cycle or with ‘initialize travel limits’ tester request.

Terminal condition: Terminal 15 ON

Voltage condition:

Electrical system voltage Terminal 87 >10.0 V

Condition for fault memory entry

following renewed successful execution of the travel limit

initialization routine

Action in service

1. Use tester request to repeat the VVT travel limit

initialization routine 2. If Item No.1 is not OK, it will be

necessary to check the VVT mechanical components /VVT

servo motor

55 ms

Action in service

1. Use tester to request initialization of travel limits and note

whether travel limit initialization routine executes without

problems. 2. If Item 1 is not OK, replace VVT motor and

repeat Item 1

3. If replacing VVT motor fails to resolve the problem:

Open the valve cover and check the VVT for mechanical

stiction and seizure.
