Toyota Yaris XP210 (2020-2025) Reapir and Service Manual: A Camshaft Position Actuator Bank 1 Circuit Open (P001013)

DESCRIPTION The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing. The cam timing oil control solenoid assembly (for intake camshaft) operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly and supply engine oil...
