P2DEECylinder 5 Intake Valve Lift Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2DEE can only occur on engines with five or more cylinders and means the intake valve lift of cylinder 5 is outside the commanded range or late. Two-step lift reached V6 engines such as the 3.6 L Pentastar, which FCA updated for 2016. An FCA patent built around switchable roller finger followers, each with an oil control valve, detects a valve stuck in the wrong lift mode from the ripple of camshaft speed taken from the cam position sensor: a filtered amplitude minus a stored nominal value, squared, gives a stuck-valve index that is checked against a threshold within about two engine cycles. Whether a given make stores such a fault as P2DEE is not published. Expect a cylinder 5 misfire, rough idle and the lamp.
- What you may notice
- Check engine light on

- Ticking from the valvetrain on one bank
- Likely causes
- LikelySwitching roller finger follower of cylinder 5 stuck in one mode
- PossibleOil control valve for the lift switching sticking or contaminated
- PossibleOil pressure too low to move the lock pins
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
