P2D2ECold Start Intake Manifold Runner Performance Bank 2
- 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
- P2D2E is the bank 2 version of the cold start runner check, so it only appears on V or boxer engines whose second cylinder row has its own flaps or actuator. The module compares the position commanded for the cold start phase with the feedback from that bank and flags a flap that stays short of target. Both FCA bulletins for the 2020 Ram 1500 3.0 l EcoDiesel V6 (18-008-21, 18-002-23) list it together with P2D2D, and the cure is a PCM reflash; when both banks report at once, software or a shared supply is more likely than two failing flaps. If only bank 2 is stored, inspect that side's shaft, linkage and connector. CARB demands the check for charge motion and swirl valves during cold starts; outside that window the same fault is P200B.
- What you may notice
- Check engine light, often with no other complaint
- Uneven idle shortly after a cold start
- P2D2D or P200B may appear alongside
- Likely causes
- LikelyEngine control software, especially when P2D2D is stored at the same time
- PossibleDeposits making the bank 2 flap shaft stiff in the cold
- PossibleBank 2 actuator, linkage or connector worn or corroded
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
