The APDTY 028318 Variable Valve Timing (VVT) Solenoid is an OE-replacement oil control valve designed for 2.0L engines in select Hyundai and Kia vehicles. This solenoid regulates engine oil flow to the variable valve timing actuator, optimizing camshaft timing for improved fuel economy, performance, and emissions. When it fails, drivers commonly experience rough idle, stalling, reduced power, and check engine lights with codes P0011 (intake cam advance) or P0014 (exhaust cam retard). The APDTY 028318 replaces OE part numbers 24355-23770, 24355-23800, 2435523763, and 24355237632, restoring proper engine timing control.

What Does the Variable Valve Timing Solenoid Do?
The Variable Valve Timing (VVT) solenoid—also called an oil control valve (OCV)—is an electromechanical valve that controls the flow of engine oil to the VVT actuator (also called a cam phaser) mounted on the camshaft. By modulating oil pressure, the solenoid advances or retards camshaft timing relative to the crankshaft, optimizing valve overlap for different engine speeds and loads.
Key functions include:
- Improved fuel economy: Optimizes combustion efficiency at cruising speeds
- Increased power: Adjusts timing for maximum performance during acceleration
- Reduced emissions: Fine-tunes valve events to meet emissions standards
- Smoother idle: Maintains stable timing at low RPM
The engine control module (ECM) sends pulse-width-modulated signals to the solenoid, which adjusts oil flow in real time. When the solenoid fails, the ECM cannot control cam timing, triggering diagnostic trouble codes and performance issues.
What Are the Symptoms of a Bad VVT Solenoid?
A failing or stuck VVT solenoid disrupts camshaft timing control, causing noticeable drivability problems. Common symptoms include:
- Check engine light: Most often with codes P0011 (intake cam timing over-advanced), P0014 (exhaust cam timing over-retarded), P0010, P0013, or P0020
- Rough or unstable idle: Engine shakes or surges at stoplights
- Stalling: Engine may die at idle or during deceleration
- Loss of power: Poor acceleration, hesitation, or sluggish performance
- Reduced fuel economy: Inefficient combustion from incorrect cam timing
- Engine noise: Rattling or ticking from the timing chain area, especially on cold starts
- Hard starting: Extended cranking or difficulty starting when warm
If you scan your vehicle and retrieve a VVT-related code, inspect the solenoid for oil sludge buildup (a common cause of sticking) and check engine oil level and condition. Low or dirty oil can cause solenoid malfunction even if the part itself is functional.

How to Replace a VVT Solenoid (General Overview)
Replacing a VVT solenoid is a straightforward job for DIYers with basic hand tools. The solenoid is typically located on the engine's valve cover or timing chain cover, near the front of the engine. Always consult your vehicle's service manual for torque specifications and exact procedures.
General replacement steps:
- Disconnect the battery: Remove the negative cable to prevent accidental shorts.
- Locate the solenoid: It is usually mounted on the front or side of the cylinder head, connected by a single electrical connector and held by one or two bolts.
- Unplug the connector: Press the release tab and pull the connector straight off.
- Remove the mounting bolt(s): Use a 10mm socket or appropriate size.
- Pull out the old solenoid: Twist gently if stuck; expect a small amount of engine oil to drip out.
- Inspect the solenoid screen/filter: Clean or replace if clogged with sludge.
- Install the new APDTY 028318: Lubricate the O-ring with clean engine oil, insert the solenoid, and torque the bolt to spec (typically 7–9 ft-lbs; verify in your manual).
- Reconnect the electrical connector and battery.
- Clear codes and test drive: Use an OBD-II scanner to clear any stored codes, then drive to confirm the issue is resolved.
Pro tip: Use fresh, high-quality engine oil and replace your oil and filter if they are dirty or overdue. Sludge buildup is a leading cause of VVT solenoid failure.
