P2112 Throttle Actuator A Control System - Stuck Closed

P2112 is the mirror image of P2111: throttle A opens less than commanded. Ford sets it when the actual angle stays more than 6 degrees below the desired angle for about 500 ms (MIL after two drive cycles, ETC lamp at once) and lists it in its 2020-2023 and 2024 summaries. Ford's SSM 50203 names it for Ranger/Bronco with ice behind the throttle. Mazda uses the number differently: its bulletins for the CX-9 and Mazda3 describe P2112 as a throttle motor current fault set after cold starts below freezing, cured by draining condensate or a PCM update. Ice, thick carbon or a jammed gear are the usual causes; the engine may idle poorly or lack power.

Likely causes

Frozen condensate locking the throttle plate
Heavy carbon restricting plate movement
Jammed gear or weak motor in the throttle body
PCM logic needing an update

Symptoms

  • Lack of power after a cold start
  • Low or unstable idle, possible stalling
  • Engine and wrench lamp on

Repair estimate
