P211FThrottle Actuator B Control Module Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
