What P2110 means
P2110 records that engine speed has been capped because throttle A can no longer be controlled safely. Ford's 2012 summary sets it on second-generation ETC when both throttle position sensors fail or Ford's throttle plate controller (TPPC) reports a fault, with MIL and wrench lamp; rpm is then capped by a pedal-dependent limit enforced through fuel and spark. FCA uses it widely: a Ram 1500 3.6L bulletin (09-023-23) pairs it with throttle icing (P2072, P2118), and Jeep Renegade/Fiat 500X PCM updates cure false settings. Repair the companion code first. Bank B counterpart is P210F; other fallback states are P2104-P2106.
P2110 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2110
- Engine will not rev beyond a low limit
- Engine warning lamp on
- Stop/start disabled or hard start in frost
Common causes of P2110
- Most likelyIce on the throttle plate after a cold soak
- PossibleLoss of both throttle position sensor signals
- PossiblePCM software setting the code falsely (update available)
- Less likelyWorn or faulty electronic throttle body
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2110 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. |
| 10 | The exact fault in that area. |
What to do next
- Note P2110 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 P2110
What does P2110 mean?
P2110 means "Throttle Actuator A Control System - Forced Limited RPM". P2110 records that engine speed has been capped because throttle A can no longer be controlled safely. It is a generic code, so it means the same on every make.
Is it safe to drive with P2110?
Drive gently and only to a workshop. With P2110 the car can go into limp mode (reduced power) to protect itself.
Will P2110 fail an emissions test?
Yes, it can. P2110 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 P2110 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2110 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
