P200BIntake 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
- P200B judges whether the flaps of bank 2 move as commanded and settle where they should; it needs a V engine whose second bank has its own flap set or position feedback. The clearest public user is FCA's 3.0 V6 EcoDiesel: bulletins for the Jeep Grand Cherokee and Ram 1500 from 2014 onward, and 18-002-23 for the 2020 Ram 1500 with the third-generation engine, list P200A and P200B together and cure them by reprogramming the PCM, together with the cold-start variants P2D2D/P2D2E. That points to calibration as one cause rather than hardware alone. FCA publishes no thresholds; GM's inline-engine bank 1 check P200A shows the typical approach, comparing learned end stops with a window and timing each stroke. Before replacing a manifold, check for a software update, then the actuator and linkage on bank 2 only.
