P2DED: Cylinder 4 Intake Valve Lift Range/Performance
Standardized SAE J2012 code · P2Dxx codes
What does P2DED mean?
The variable intake valve lift on cylinder 4 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
