P2DEE Cylinder 5 Intake Valve Lift Range/Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Switching roller finger follower of cylinder 5 stuck in one mode
Oil control valve for the lift switching sticking or contaminated
Oil pressure too low to move the lock pins

Symptoms

  • Check engine light on
  • Misfire on cylinder 5
  • Ticking from the valvetrain on one bank
