What P211A means
P211A means the second throttle on a twin-throttle engine stays further open than requested. Ford documents it in its 2020-2023 and 2024 summaries for applications with an ETB B, with MIL and wrench lamp and detection within 5 seconds; in 2024 it is shown as P210A with failure-type byte 72, matching P2111/P2100-72 for throttle A. For the A throttle Ford uses a 6-degree gap between desired and actual angle, and the B check is built the same way. With one bank getting extra air, idle rises and the engine runs unevenly; the controller usually limits power. Look for ice, carbon or a broken return spring at throttle body B. Bank 1 counterpart is P2111, stuck closed P211B.

- Emissions testCan fail
- Limp modePossible

- Clears after repairWhen cleared with a scanner
Symptoms of P211A
- High or hunting idle
- Engine and wrench lamp on
- Reduced power
Common causes of P211A
- Most likelyIce or carbon holding throttle B open
- PossibleBroken return spring or gear in throttle body B
- Less likelyFaulty throttle motor B or its position sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P211A 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. |
| 1A | The exact fault in that area. |
What to do next
- Note P211A 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 P211A
What does P211A mean?
P211A means "Throttle Actuator B Control System - Stuck Open". P211A means the second throttle on a twin-throttle engine stays further open than requested. It is a generic code, so it means the same on every make.
Is it safe to drive with P211A?
Drive gently and only to a workshop. With P211A the car can go into limp mode (reduced power) to protect itself.
Will P211A fail an emissions test?
Yes, it can. P211A 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 P211A to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P211A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
