What P2112 means
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.
P2112 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2112
- Lack of power after a cold start
- Low or unstable idle, possible stalling
- Engine and wrench lamp on
Common causes of P2112
- Most likelyFrozen condensate locking the throttle plate
- PossibleHeavy carbon restricting plate movement
- PossibleJammed gear or weak motor in the throttle body
- Less likelyPCM logic needing an update
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2112 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 12 | The exact fault in that area. |
What to do next
- Note P2112 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2112
What does P2112 mean?
P2112 means "Throttle Actuator A Control System - Stuck Closed". P2112 is the mirror image of P2111: throttle A opens less than commanded. It is a generic code, so it means the same on every make.
Is it safe to drive with P2112?
Drive gently and only to a workshop. With P2112 the car can go into limp mode (reduced power) to protect itself.
Will P2112 fail an emissions test?
Yes, it can. P2112 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2112 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2112 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
