What P200B means
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.
P200B at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P200B
- Malfunction indicator lamp on
- Often no noticeable change in driving
Common causes of P200B
- PossibleEngine software with an available update (FCA 3.0 EcoDiesel)
- PossibleBank 2 actuator slow or failed
- PossibleFlaps on bank 2 sticking from soot or carbon
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P200B means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 0B | The exact fault in that area. |
What to do next
- Note P200B 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 P200B
What does P200B mean?
P200B means "Intake Manifold Runner Performance (Bank 2)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P200B?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P200B fail an emissions test?
Yes, it can. P200B 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 P200B to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P200B clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
