System check
HINT:
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 ...

Fail-safe chart
If any of the following DTCs are set, the ECM enters fail-safe
mode to allow the vehicle to be driven temporarily.
HINT:
*1: The vehicle can be driven slowly when the accelerator
pedal is depressed firmly and slowly. If the accelerator
pedal is depressed quickly, the vehicle may ...
