Hitachi VTC0002 Engine Variable Valve Timing (VVT) Solenoid Housing

Hitachi VTC0002 Variable Timing Control Cover

Hitachi VTC0002 is a Variable Timing Control Cover Assembly for the engine valve train. It houses the variable timing solenoid valve and mounts to the timing chain case front cover to help regulate oil pressure to the camshaft phasors that control valve timing.

Compatible With 2016-2019 INFINITI Q50, left, and 2017-2019 INFINITI Q60, left. This part cross-references Nissan (e.g., 13040-5CA0B) for the same application.

Key Features

• Aluminum cover assembly for the variable valve timing system
• Houses the variable timing solenoid valve
• Mounts to the timing chain case front cover
• Supports oil-pressure control to the camshaft phasors
• OE-style replacement for select INFINITI VVT applications

Detailed Description

The Hitachi VTC0002 is an engine variable valve timing solenoid housing used in the valve train system. By enclosing the solenoid valve and interfacing with the timing chain case front cover, it helps direct oil pressure to the camshaft phasors so the engine can adjust valve timing as commanded. This part is a direct-fit service component for select INFINITI Q50 and INFINITI Q60 models with left-side application coverage.

Common Issues It May Address

• Variable valve timing fault codes related to solenoid housing failure
• Oil leakage at the timing cover area
• Erratic camshaft phaser operation
• Rough idle or reduced engine response tied to VVT control issues
• Physical damage or wear to the original cover assembly

Installation Notes and Tips

Verify engine code, side, and model-year coverage before installation. Inspect the mating surfaces, seals, and related VVT components for wear or contamination, and follow the vehicle service procedure for torque and oil-system checks after replacement. Confirm the part number VTC0002 against the original unit before ordering.

Quality Assurance

Hitachi manufactures this cover assembly as a service replacement for the factory variable timing control system used on select INFINITI applications. The part number VTC0002 is built to match the OE-style layout for the specified fitment.
