Infiniti M37 Engine Variable Valve Timing (VVT) Solenoids

Infiniti M37 Engine variable valve timing (vvt) solenoids

Starting at $56.95, AutoBuffy stocks 12 Engine Variable Valve Timing (VVT) solenoids from Gates, SKP, and Standard Ignition to fit the Infiniti M37. The VVT solenoid controls oil flow to the camshaft phaser, allowing the engine to advance or retard valve timing for optimal power and efficiency. When it fails, the engine loses that precision—expect rough idle, poor fuel economy, and a check engine light that won't go away.

Signs your Infiniti M37 needs a new VVT solenoid

  • Check engine light with stored codes P0010, P0011, P0013, P0014, or related camshaft position/timing codes
  • Rough or erratic idle that worsens when the engine is cold and oil hasn't fully circulated
  • Noticeable loss of low-end torque or sluggish throttle response during acceleration
  • Fuel economy drops measurably because valve timing is stuck in a fixed, non-optimized position
  • Engine rattles or ticks on startup—especially a brief metallic knock as the phaser hunts for oil pressure
  • Failed emissions test due to incomplete readiness monitors caused by ongoing VVT system faults

Which VVT solenoid should you buy for your Infiniti M37?

The main decisions are fitment position (intake, exhaust, or both camshafts depending on your engine), and whether you choose OEM-equivalent quality or a premium unit with tighter tolerances. Oil sludge is the leading cause of solenoid failure, so screen mesh quality and valve body material matter as much as brand name.

OEM-Replacement (exact-fit)
Best for
Restoring factory performance at a reasonable cost
What you get
Direct plug-and-play fitment, correct resistance spec, no recoding required
Premium / OE-Supplier Grade
Best for
High-mileage engines or repeat failures caused by marginal oil quality
What you get
Tighter internal tolerances, improved screen mesh to resist sludge, longer service life
Intake-Side Only
Best for
Engines with a single variable cam (intake only) or when diagnosis confirms only one side is faulty
What you get
Targeted repair that avoids unnecessary parts cost; confirm with live scan data first
Intake + Exhaust Pair
Best for
Dual-VVT engines where both solenoids share mileage and oil exposure
What you get
Balanced repair that prevents the second unit from failing shortly after; often cost-effective as a set

Replacing the VVT solenoid on a Infiniti M37

Easy⏱ 30–90 minutesOBD-II scanner (to read and clear codes)Socket set and ratchet (metric)Flathead screwdriver or trim tool (electrical connector release)Clean lint-free ragsTorque wrench

The solenoid is typically mounted on the front or side of the cylinder head and secured by one or two bolts, making it accessible on most engines without major disassembly. Disconnect the battery negative terminal and electrical connector, remove the retaining bolt(s), and pull the solenoid straight out—then clean the bore before installing the new unit with fresh O-rings. Snug the retaining bolt to spec using a torque wrench, reconnect all connectors, and clear fault codes before test-driving to confirm the repair.

Frequently asked questions

How much does it cost to replace VVT solenoids on a Infiniti M37?
Parts start at $56.95 at AutoBuffy. A shop will add one to two hours of labor on most engines, though dual-cam setups or tight engine bays can take longer. Doing it yourself keeps the total close to the part price alone, making this one of the more accessible engine repairs.
Can I drive my Infiniti M37 with a bad VVT solenoid?
You can drive short distances, but it isn't advisable. A failed solenoid locks valve timing in a fixed position, reducing power and fuel economy. More critically, a stuck-open solenoid can flood the camshaft phaser with uncontrolled oil pressure, accelerating wear on the phaser and timing chain over time.
Will replacing the VVT solenoid on my Infiniti M37 clear the check engine light?
Yes, if the solenoid was the root cause. After replacement, use an OBD-II scanner to clear stored codes and complete a drive cycle so the PCM can confirm the repair. If the code returns, inspect oil pressure, camshaft phaser condition, and timing chain stretch before replacing the solenoid again.
How often do VVT solenoids need to be replaced on a Infiniti M37?
There is no fixed replacement interval. Solenoids typically last well into high mileage when oil changes are performed on schedule with the correct viscosity. The most common cause of early failure is oil sludge blocking the solenoid's internal screen. Staying current on oil changes is the best preventive measure.
Does oil type or change interval affect VVT solenoid life on a Infiniti M37?
Significantly. VVT solenoids rely on clean, correctly viscous oil to open and close precisely. Using the wrong viscosity or stretching oil change intervals allows sludge to accumulate on the solenoid's filter screen, restricting flow. Always use the grade specified for your Infiniti M37 and change it within the manufacturer's recommended interval.
Do I need to replace the VVT solenoid O-rings on a Infiniti M37?
Yes, and most quality replacement solenoids include new O-rings in the box. The O-rings seal the solenoid against the engine block or head; reusing old, compressed O-rings risks an oil leak at the installation point. Lightly lubricate new O-rings with fresh engine oil before installation to seat them properly.
