Overview

The Hitachi VTG0006 is a variable valve timing sprocket engineered to restore precise hydraulic control to engines equipped with VVT systems. As a Tier 1 OEM supplier, Hitachi Astemo manufactures this component to the exact tolerances of the original factory part — the precision-machined tooth profile maximizes chain engagement while reducing wear, and the optimized oil ports deliver consistent hydraulic response under varying engine loads and temperatures. It is supplied 100% new, making it a dependable choice for high-mileage engine restorations and warranty-conscious repairs.

VVT sprocket replacement should be performed alongside a thorough inspection of related components — oil passages, VVT solenoids, and engine oil condition all affect system performance. A clean hydraulic circuit is essential for the sprocket to operate correctly after installation. Fitment is application-specific; confirm compatibility using your vehicle's year, make, model, and engine code. Installation requires engine timing knowledge and, in most cases, a diagnostic scan tool to clear fault codes and verify VVT operation after the repair is complete.

Key Features

ENHANCED PERFORMANCE: Astemo VTG0006 Engine Variable Valve Timing (VVT) Sprocket is engineered to deliver dependable performance, durability, and OE-quality reliability

LONG-LASTING DURABILITY: Supplier for variable timing gears remanufactured performance and durability standards for this application designed to reduce wear and tear while increasing chain-to-tooth engagement and ports create optimal flow passages and minimal friction for smooth operation Astemo’s Variable Timing Solenoid (VTSs) precisely regulate oil flow to the Variable Timing Gear to allow the engine to adjust timing for optimal performance and fuel economy

PRECISION ENGINEERED: Our VTS have a(n) optimally designed electromagnet(s) requiring less energy to maintain operating positions resulting in more consistent oil flow while precision machined ports and high-quality seals create less pressure drop

PREMIUM QUALITY: Additional O-ring located in the solenoid housing prevents water from damaging electrical components increasing dependability

PREMIUM MATERIALS: Designed to meet the exact needs of each specific vehicle, Astemo’s Variable Timing Solenoids are the premium choice

Pros & Cons

👍 Pros

  • Manufactured by Hitachi Astemo, a Tier 1 OEM supplier with direct factory production relationships.
  • 100% new construction — no remanufactured or refurbished components.
  • Precision-machined tooth profile maximizes chain-to-tooth engagement while reducing chain wear over time.
  • Optimized oil flow ports minimize internal friction for consistent VVT hydraulic response.
  • Built to OE performance and durability standards for the specific vehicle application.

👎 Cons

  • Vehicle fitment is application-specific — compatibility must be confirmed before purchase.
  • Installation requires timing system expertise and typically a scan tool to verify proper operation post-install.
  • No installation hardware or ancillary gaskets included — supplementary parts must be sourced separately.
  • Best results require addressing oil condition and passage cleanliness alongside the sprocket replacement.

Frequently Asked Questions

The sprocket regulates oil flow to the variable valve timing system, allowing the engine control module to advance or retard camshaft timing based on load and RPM — optimizing both power output and fuel economy across the rev range.
This is 100% new — never remanufactured or rebuilt. Hitachi Astemo produces it as a Tier 1 OEM supplier, meaning it's made to the same specifications as the original factory part.
A worn or stuck VVT sprocket is a common cause of timing-related fault codes, but it's not the only cause. Confirm the sprocket is the root cause before replacement — oil condition, VVT solenoid function, and passage cleanliness can also trigger these codes.
This sprocket is engineered for specific vehicle applications. Always verify compatibility using your vehicle's year, make, model, and engine code before ordering.
Yes — proper installation requires engine timing knowledge, correct torque specifications, and typically a diagnostic scan tool to clear codes and verify variable valve timing operation after replacement.
