P2D2E Cold Start Intake Manifold Runner Performance Bank 2
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.
Likely causes
Symptoms
- Check engine light, often with no other complaint
- Uneven idle shortly after a cold start
- P2D2D or P200B may appear alongside
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
