Product Overview

The variable valve lift solenoid, OEM number 5047897AC, is an electrically controlled solenoid that directs engine oil pressure to actuate the variable valve timing and lift system, adjusting valve operation to match engine speed and load. It cycles constantly while the engine runs, and its internal components wear with use, which makes it a regular replacement item in the engine timing and valvetrain category.

A worn or clogged solenoid can cause rough running, reduced power, and check engine warning lights, so a properly functioning replacement matters. GSK Auto manufactures this solenoid to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm the OEM number match before shipping.

What Is a Variable Valve Lift Solenoid?

Function: The variable valve lift solenoid controls oil flow to the camshaft phaser or lift mechanism, allowing the engine control unit to adjust valve timing and lift as engine speed and load change.

Working Principle: The engine control unit sends an electrical signal to the solenoid, which opens to direct pressurized engine oil to the camshaft actuator. This oil pressure shifts the camshaft's phase or valve lift profile, optimizing the engine's breathing for the current operating condition, whether that calls for more power, better fuel economy, or lower emissions.

Importance: The solenoid is central to how the engine adjusts valve operation on the fly. A malfunctioning solenoid can prevent the variable valve system from working correctly, affecting power delivery, fuel efficiency, and emissions.

Common Failures & Signs: Check engine light with a camshaft position or variable valve timing trouble code. Rough or unstable idle. Rattling or ticking noise from the valvetrain, especially on startup. Loss of power or poor acceleration. Reduced fuel economy. Engine going into a protective mode with reduced performance.
