P2DEC: Cylinder 3 Intake Valve Lift Range/Performance

Standardized SAE J2012 code · P2Dxx codes

What does P2DEC mean?

The variable intake valve lift on cylinder 3 does not reach the commanded position within tolerance. Mechanism wear or actuator force degraded.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Common causes

  • High Variable lift mechanism worn
  • Medium Oil pressure to actuator low
  • Low Sensor element aged beyond calibration window

Likelihood is a general estimate across vehicles; your make and model may differ.
