Camshaft Oil Control Solenoid for Subaru AVCS

This precision solenoid manages oil flow to the cam phaser in Subaru AVCS/VVT systems. It keeps valve timing accurate for smooth idle, strong mid‑range torque, and clean emissions. If your engine hunts at idle, feels flat on acceleration, or flashes a check engine light, a tired solenoid is often the cause.

Why this part is needed

Clean, metered oil pressure is vital for variable valve timing. The solenoid directs oil to advance or retard the cam, improving fuel economy and response ⛽. Fresh oil and a healthy valve protect chains, guides, and cam gears from stress.

How it works

The ECU pulses the coil (PWM). An internal spool and fine mesh screen modulate oil to the cam phaser. The result: precise cam angle at every RPM for efficient combustion.

What happens if it fails ⚠️

Rough start, rattly cold runs, hesitation, poor mileage, and codes like P0011/P0021. Long-term neglect can wear the phaser and timing components.

Tech notes ✅

Use correct viscosity oil, clean the port, replace the O‑ring, and torque to spec. If sludge is present, inspect both bank valves.
