P211A Throttle Actuator B Control System - Stuck Open

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Ice or carbon holding throttle B open
Broken return spring or gear in throttle body B
Faulty throttle motor B or its position sensor

Symptoms

  • High or hunting idle
  • Engine and wrench lamp on
  • Reduced power
