P2112 on Ford
Throttle Actuator Control System - Stuck Closed
P2112 on Ford vehicles indicates throttle actuator control system - stuck closed. Au7o has documented this code across 5 Ford models — most commonly on Explorer, Five Hundred, Freestyle. P2112 means the throttle actuator control (electronic throttle) system is stuck in the closed position. On drive-by-wire engines the computer moves the throttle plate with an electric motor and confirms its position with sensors; when it commands the throttle open but the plate won't move past closed, this code sets. This usually triggers limp/failsafe mode with greatly reduced power, a poor or surging idle, or a no-acceleration condition. It points to a mechanical or electrical problem in the throttle body or its control circuit. Typical repair costs on Ford range from $100 to $900, depending on the specific model and root cause.
Common Causes of P2112
- •Carbon buildup or debris binding the throttle plate
- •Failed throttle body actuator motor
- •Faulty throttle position sensor inside the throttle body
- •Damaged or corroded throttle body connector/wiring
- •Loss of power or ground to the throttle body
- •Seized or mechanically stuck throttle plate
- •Faulty throttle control circuit in the PCM/ECM
P2112 on Ford by Model
Ford Explorer(1 issue)
- Throttle Body Failure on 4.6L V8 Causing Wrench Light, Limp Mode, and Sudden Loss of Power2006-2010
Later 4th-generation Explorers with the 4.6L 3-valve V8 commonly suffer electronic throttle body problems. Owners report the wrench light illuminating, the vehicle abruptly entering fail-safe mode, and the engine losing throttle response or dropping to idle while driving. This issue is well documented across Ford products using similar electronic throttle bodies and is frequently associated with internal motor or throttle position sensor faults.
Ford Five Hundred(1 issue)
- Electronic Throttle Body Failure2005-2007
The electronic throttle body sticks or fails, causing the engine to enter limp mode with reduced power. The throttle plate bore wears and allows the plate to stick. May trigger wrench warning light on the dash.
Ford Freestyle(1 issue)
- Throttle Body Malfunction and Unintended Forward Surge2005-2007
The Ford Freestyle is subject to a significant safety issue where the vehicle surges or lunges forward unexpectedly at low speeds when in gear, even without the accelerator pedal being applied. The NHTSA investigated 238 complaints about this behavior, finding that a programming error in the engine computer causes the electronic throttle body to malfunction, particularly when the engine is under load from A/C operation, steering at full lock, or carrying heavy loads. In 18 reported cases, the surge caused accidents. Ford eventually issued a recall in December 2012 to reprogram the throttle body or replace it and reimburse owners who had already paid for the repair.
Ford Transit(1 issue)
- 3.7L Ti-VCT Throttle Body Failure / Electronic Throttle Control (ETC) Limp Mode2015-2019
Owners report sudden loss of power with a wrench light and reduced throttle response, often while cruising or accelerating. NHTSA complaints and Ford service information describe electronic throttle body internal faults (TPS/actuator) that can trigger ETC failsafe and limp mode on 3.7L Ti-VCT Transits. The condition may be intermittent at first and then become frequent, especially with heat/soak and higher mileage.
Ford Transit Connect(2 issues)
- Throttle Body/ETC Fault Causing Limp Mode (Reduced Engine Power)2014-2021
Owners report sudden reduced power, poor throttle response, and limp-home behavior due to electronic throttle body contamination/wear or throttle actuator control faults. The issue can be intermittent and may clear after a key cycle, then recur, which is a common pattern in NHTSA complaints and owner reports. It often sets throttle/ETC-related DTCs and can be triggered by carbon buildup or failing throttle position sensing.
- PCM Software Calibration Causing Intermittent Stalling2017-2020
Multiple 2017-2020 Transit Connect owners report intermittent stalling at idle or during low-speed maneuvers, traced to PCM software calibration issues. The engine drops RPMs erratically and stalls, particularly when the AC compressor engages or when transitioning from reverse to drive. Ford released TSB 19-2346 addressing this with an updated PCM calibration, but many vehicles remain unflashed.

What does P2112 mean on Ford?▼
P2112 stands for "Throttle Actuator Control System - Stuck Closed." P2112 means the throttle actuator control (electronic throttle) system is stuck in the closed position. On drive-by-wire engines the computer moves the throttle plate with an electric motor and confirms its position with sensors; when it commands the throttle open but the plate won't move past closed, this code sets. This usually triggers limp/failsafe mode with greatly reduced power, a poor or surging idle, or a no-acceleration condition. It points to a mechanical or electrical problem in the throttle body or its control circuit. On Ford specifically, this code is documented across 5 models.
What causes P2112 on Ford vehicles?▼
Common causes on Ford: Carbon buildup or debris binding the throttle plate, Failed throttle body actuator motor, Faulty throttle position sensor inside the throttle body, Damaged or corroded throttle body connector/wiring, Loss of power or ground to the throttle body. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2112 on a Ford?▼
