P2112Throttle Actuator A Control System - Stuck Closed
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Lack of power after a cold start
- Low or unstable idle, possible stalling
- Engine and wrench lamp on
- Likely causes
- LikelyFrozen condensate locking the throttle plate
- PossibleHeavy carbon restricting plate movement
- PossibleJammed gear or weak motor in the throttle body
- RarePCM logic needing an update
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
