What P211B means
P211B is set when throttle B on a twin-throttle engine opens less than the controller asks for. Ford lists it for its dual-throttle applications in the 2020-2023 summary and in 2024 as P210A with failure-type byte 73, each with MIL, wrench lamp and detection in under 5 seconds; the A-side logic it mirrors is P2112, where actual angle trailing the target by more than 6 degrees counts as a fault. One bank is then starved of air: the engine feels weak, may stumble at idle and often drops into limp mode. Ice after a frosty night, heavy carbon or a jammed gear train in throttle body B are the usual suspects. The opposite direction is P211A, position control errors P210B.

- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P211B
- Weak acceleration, limp mode
- Rough idle
- Engine and wrench lamp on
Common causes of P211B
- Most likelyFrozen condensate locking throttle B
- PossibleHeavy carbon restricting throttle B
- PossibleJammed gear or weak motor in throttle body B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P211B means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 1B | The exact fault in that area. |
What to do next
- Note P211B 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 P211B
What does P211B mean?
P211B means "Throttle Actuator B Control System - Stuck Closed". P211B is set when throttle B on a twin-throttle engine opens less than the controller asks for. It is a generic code, so it means the same on every make.
Is it safe to drive with P211B?
Drive gently and only to a workshop. With P211B the car can go into limp mode (reduced power) to protect itself.
Will P211B fail an emissions test?
Yes, it can. P211B 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 P211B to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P211B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
