Common Symptoms This Part May Address

• Check engine light related to VVT or cam timing faults
• Rough idle or inconsistent engine operation
• Reduced throttle response during acceleration
• Cam timing performance codes on Toyota 4Runner or Toyota FJ Cruiser
• Oil control valve or VVT solenoid malfunction on the exhaust side

Installation Notes

Verify the engine code, connector style, and exhaust (left) position before installation. Inspect the oil passages and related seals for contamination or sludge, since restricted oil flow can affect VVT operation. Clear diagnostic trouble codes after installation and confirm proper system response with a scan tool.
