Technical Description

Locking pin

Note: when removing/installing the VVT-actuator, always make sure the actuator is locked in its rest position. This can be verified by means of reference marks on the actuator housing (see picture). Engine timing procedure can only be performed correctly when the VVT-actuators are in their rest position.

Electrical timing check The diagnostics system can be used to check the correct electrical timing of the engine, by reading the values taken on both banks. In the parameters environment, with the vehicle in a steady state and running at idling speed, it is possible to ascertain the correctness of the electrical timing, especially in the case of repeated misfiring.
