What P2DEE means

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.

  • Typical labor1 to 8 hours
  • Clears after repairWhen cleared with a scanner

Symptoms of P2DEE

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

Common causes of P2DEE

  • Most 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

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next

  • Note P2DEE and any other codes stored with it: several codes together often point to one cause.
  • Check for loose connectors and damaged wiring around the parts the code names.
  • Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
  • Clear the code only after the repair. If it comes back, the fault is still there.

Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.

Questions about P2DEE

What does P2DEE mean?

P2DEE means "Cylinder 5 Intake Valve Lift Range/Performance". 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. It is a generic code, so it means the same on every make.

Is it safe to drive with P2DEE?

Drive gently and only to a workshop. With P2DEE the car can go into limp mode (reduced power) to protect itself.

Will P2DEE fail an emissions test?

Yes, it can. P2DEE is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.

How hard is P2DEE to fix?

Difficulty: hard. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.

Will P2DEE clear itself after the repair?

Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
