Description

Function of the VVTi Oil Control Valve Solenoid

The VVTi oil control valve solenoid directs pressurised oil to the VVTi gear to adjust camshaft timing. Controlled by the ECU, it precisely varies the oil flow to advance or retard valve timing based on engine speed and load. A malfunctioning solenoid causes rough idle, poor performance, rattling noise on startup, reduced fuel economy, and a check engine light.

Common Diagnostic Trouble Codes (DTCs)

A generic OBD reader displays the standard 5-character code shown below.

• P0010 — Camshaft Position Actuator A Circuit / Open (Bank 1) – the OCV solenoid circuit
• P0011 — Camshaft Position A – Timing Over-Advanced or System Performance (Bank 1, solenoid stuck)
• P0013 — Camshaft Position Actuator B Circuit / Open (Bank 1, exhaust OCV / dual-VVT only)
• P0014 — Camshaft Position B – Timing Over-Advanced or System Performance (Bank 1, dual-VVT only)

Why order it from Partszar

A faulty sensor, coil or starter feeds the engine the wrong signal, so it runs rich, misfires, will not start or drops into limp mode, and the fault light stays on until it is fixed. Once this is replaced the ECU gets what it expects and the vehicle runs the way it did when it was new.
