Performing a SYSTEM CHECK enables the system,
which consists of the multiple actuators, to be operated
without removing any parts. In addition, it can show
whether or not any DTCs are set, a ...
Camshaft Position "A" Actuator Circuit
DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve
(OCV) and VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control sig ...
