P2CE0Cold Start Cylinder 6 Deactivation/Intake Valve Control Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2CE0 closes this series of cold start codes; numbering ends at cylinder 6 although many deactivation engines have eight cylinders. It indicates that cylinder 6 did not reach the valve state demanded during the cold start routine. No manufacturer documents P2CE0 publicly. Related evidence shows how such faults look in the field: a 2025 Ram bulletin (18-002-25) for the 2023 Ram 1500 with the 5.7 L Hemi MDS eTorque lists cylinder 6 deactivation and reactivation codes (P3441, P1416) with rough idle and misfire during warm-up, and fixes them with new PCM software. GM's L84 marks a cylinder 6 that keeps breathing as P349D, Type B. Look at software and oil supply before replacing lifters; the generic check outside cold start is P3442.
- What you may notice
- Rough idle or misfire while warming up
- Check engine lamp, often with a cylinder 6 misfire code
- Cylinder deactivation may stay disabled afterwards
- Likely causes
- LikelyDeactivating lifter or rocker on cylinder 6 not switching
- PossibleEngine control software that misjudges or mis-times the cold start switching, fixed by reprogramming
- PossibleLow or delayed oil pressure after a cold start
- RareCylinder 6 control solenoid or its wiring degraded
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
