What P211F means
P211F covers a performance fault of the control function for throttle B, as distinct from a processor fault (P211E). No manufacturer documents this code publicly. For the A side, VW's 2014 data book gives a measurable example under P2108: the throttle must close below a reference point of 11.56 percent within 0.60 s. Ford uses P2108 from 2024 as base code for its processor test, which shows how differently makers fill this slot. On a twin-throttle engine P211F would apply the same kind of check to the second throttle. CARB requires such control functions to be monitored when they affect emissions. Check throttle body B for deposits and the ECU for updates; reduced power is likely.
P211F at a glance
- 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 P211F
- Engine warning lamp on
- Reduced power or limp mode
Common causes of P211F
- Most likelyThrottle B responds or closes too slowly
- PossibleControl unit software needing an update
- Less likelySupply or ground problem at the control unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P211F 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. |
| 1F | The exact fault in that area. |
What to do next
- Note P211F 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 P211F
What does P211F mean?
P211F means "Throttle Actuator B Control Module Performance". P211F covers a performance fault of the control function for throttle B, as distinct from a processor fault (P211E). It is a generic code, so it means the same on every make.
Is it safe to drive with P211F?
Drive gently and only to a workshop. With P211F the car can go into limp mode (reduced power) to protect itself.
Will P211F fail an emissions test?
Yes, it can. P211F 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 P211F to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P211F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
