Dodge Avenger Engine Variable Valve Timing (VVT) Sprockets

Dodge Avenger Engine variable valve timing (vvt) sprockets

Starting at $60.95, AutoBuffy stocks 11 Engine Variable Valve Timing (VVT) sprockets from Standard Ignition, Dorman, and Cloyes. The VVT sprocket is a phaser-driven gear that allows the camshaft to advance or retard its timing relative to the crankshaft, optimizing power, fuel economy, and emissions. A worn or failed sprocket causes erratic cam timing, triggering rough idle, poor performance, and check-engine codes that won't clear until the part is replaced.

Signs your Dodge Avenger needs a new VVT sprocket

  • Check-engine light with stored camshaft position or VVT system fault codes (e.g., P0011, P0021, P0341)
  • Rough or unstable idle that worsens when the engine is cold and the VVT system is most active
  • Noticeable loss of low-end torque or sluggish throttle response during acceleration
  • Rattling or ticking noise from the valve cover area at startup that fades after oil pressure builds
  • Fuel economy drops measurably because cam timing is stuck in a fixed, non-optimized position
  • Engine hesitates or stumbles during gear changes or when transitioning from light to heavy throttle

Which VVT sprocket should you buy for your Dodge Avenger?

The most important decision is matching the sprocket to your engine's specific camshaft position — intake, exhaust, or both — because each controls a different phase of the timing cycle and they are not interchangeable. Beyond fitment, you'll choose between OE-replacement and performance-grade units, which differ mainly in material tolerance and locking-pin design. Running fresh, correct-viscosity oil after installation is just as critical as the part itself, since the sprocket is oil-pressure actuated.

Replacing the VVT sprocket on a Dodge Avenger

Advanced⏱ 2–4 hoursCamshaft holding/locking tool set specific to the engine familySocket set and breaker bar (sprocket bolt is typically high-torque)Torque wrenchValve cover gasket setDrain pan and fresh engine oil of the correct specification

Begin by draining the oil, removing the valve cover, and using the appropriate camshaft locking tools to hold the cams absolutely stationary before loosening the sprocket bolt — skipping this step risks jumping the timing chain. Remove the old sprocket, transfer or inspect the phaser locking pin, install the new sprocket, and torque the bolt to the engine-specific specification following the manufacturer's sequence. Refill with fresh oil at the correct viscosity, clear any stored codes, and verify smooth idle and no warning lights through a full warm-up cycle.

Frequently asked questions

How much does it cost to replace VVT sprockets on a Dodge Avenger?
Parts start at $60.95 at AutoBuffy. Total repair cost depends on whether you're replacing one or both camshaft sprockets and whether the timing chain and tensioner are done at the same time. DIY saves significant labor cost; shop rates vary by region but VVT sprocket jobs often run one to three hours of billed labor.
Can I drive my Dodge Avenger with a failing VVT sprocket?
Driving short distances is possible, but it isn't advisable. A stuck or worn sprocket leaves cam timing fixed in a non-optimal position, stressing the engine and worsening fuel economy. If the locking pin fails entirely, cam timing can shift unpredictably, risking valve-to-piston contact on interference engines and potential catastrophic engine damage.
Will a new VVT sprocket clear the check-engine light on my Dodge Avenger?
Yes, if the sprocket is the root cause of the fault code. Camshaft position and VVT performance codes (such as P0011, P0021, or P0341) are directly tied to sprocket and phaser function. After replacing the sprocket and clearing codes, confirm the light stays off through a full drive cycle before assuming the repair is complete.
Does oil condition affect VVT sprocket life on a Dodge Avenger?
Significantly. The VVT sprocket relies on precise oil pressure to actuate the phaser and control the locking pin. Dirty, low, or wrong-viscosity oil starves the system, accelerates internal wear on the sprocket's locking mechanism, and is the leading cause of premature VVT failure. Always use the manufacturer-specified grade and change it on schedule.
Should I replace the timing chain when I replace the VVT sprocket on my Dodge Avenger?
It depends on mileage and chain condition. If the chain has stretch, slap, or the engine has high mileage, replacing both together makes sense — the labor overlap is substantial and doing them separately costs more overall. On lower-mileage engines with a confirmed-good chain, replacing only the sprocket is a reasonable approach.
Is replacing a VVT sprocket a DIY job on a Dodge Avenger?
It is achievable for mechanically experienced DIYers with the right tools, but it is not a beginner task. Access to the sprocket requires removing the valve cover and possibly the timing cover, and the camshaft must be held in position during the swap to prevent timing loss. Mistakes can bend valves on interference engines, so honest skill assessment matters.
