The variable valve timing (VVT) system allows the engine control module (ECM) to regulate the intake and exhaust valve phase angle providing the most optimal engine volumetric efficiency under all engine operating condition to control tailpipe emissions and engine efficiency. Variable valve timing is an emission control device and although there are various methods of operation, the typical device is regulated by oil control valves, actuator solenoids and camshaft phasers.

Product Features:

• Precision-wound coated copper windings increase product durability and life cycle.
• Hard-coated and anodized spool valve to prevent corrosion and increase service life.
• Threaded mounting bolt, hardware, and/or gaskets where applicable for easy installation.
• Thermoplastic that is resistant to high temperatures, moisture, and chemicals.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure product reliability, every time.
• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.

The Variable Valve Timing (VVT) Solenoid manages valve lift timing & oil flow within specified engine rev speeds and loads. When VVT solenoids are running normal, engine performance and fuel efficiency is optimized in all RPM ranges. A failed VVT sensor will cause intake & exhaust valves to open/close during improper times, which results in major reduced fuel economy. HL Mando VVT solenoids are OE replacement parts, same as the one found on your vehicle. Go with HL Mando VVT Solenoids to bring your car’s fuel economy back to optimal – We Are OE!
