P211F Throttle Actuator B Control Module Performance

EmissionsRelevant
Drive cycleNot required

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.

Likely causes

Throttle B responds or closes too slowly
Control unit software needing an update
Supply or ground problem at the control unit

Symptoms

  • Engine warning lamp on
  • Reduced power or limp mode
