How to diagnose and fix P2110: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Chrysler 200 · 2011–2017
The Chrysler 200 experiences intermittent engine stalling at idle, particularly when decelerating to a stop or sitting at traffic lights. On 2011 models with the 3.6L V6, NHTSA investigation PE12-016 found the PCM could run an evaporative-emissions purge monitor check at idle, creating an overly rich vapor condition that stalls the engine; carbon buildup in the electronic throttle body is a further common cause of low idle and stalling on both the 2.4L and 3.6L as the cars age. The stall often occurs without a check engine light, making diagnosis frustrating.
Common Symptoms
- Engine stalls when coming to a stop
- RPM drops very low then engine dies
- Rough or surging idle
- Stalling without a check engine light
- Engine restarts immediately after stalling
How to Fix
On a 2011 200 with the 3.6L V6, first confirm the PCM reprogramming customer satisfaction campaign (bulletin sent to dealers September 28, 2012 after NHTSA PE12-016) has been done; it is free at the dealer. Clean the electronic throttle body with CRC throttle body cleaner — remove the air intake hose and spray the butterfly valve and bore while a helper opens the throttle plate. After cleaning, perform an idle relearn: key on (engine off) for 30 seconds, then start and let idle for 5 minutes without touching the gas pedal. If stalling persists, have the dealer reflash the PCM with the latest calibration and inspect the throttle body for TPS sensor failure. Replacement throttle body costs $200-$400.

Ford Fiesta · 2011–2019
The drive-by-wire electronic throttle body (ETB) develops an internal electronic/motor fault (not just dirt) that causes the powertrain control module to command reduced power. The car drops into limp mode with a wrench/powertrain-malfunction light, often storing throttle-position or actuator-control codes.
Common Symptoms
- Sudden loss of power / limp mode while driving
- Wrench (powertrain malfunction) warning light
- Reduced or unresponsive acceleration
- Rough or high idle
- Intermittent stalling
How to Fix
Replace the electronic throttle body with an updated OEM/Motorcraft unit and perform the throttle-relearn/idle-relearn procedure afterward to prevent high idle and drivability faults.

Ford Fusion · 2010–2016
The electronic throttle body suffers internal contamination/wear of the motor contacts, causing intermittent electrical failure rather than simple dirt buildup. The result is a sudden loss of power (limp/failsafe mode) with the amber wrench (powertrain) warning light, rough idle, or stalling, sometimes in traffic. Ford acknowledged the problem with extended-warranty program 13N03 for 2010-2013 models and Customer Satisfaction Program 16B32 for certain 2015-2016 vehicles including Fusion.
Common Symptoms
- Wrench/powertrain warning light
- Sudden loss of power / limp mode
- Rough or surging idle
- Stalling
- Reduced throttle response
How to Fix
For the limp-mode failure the throttle body must be replaced (cleaning does not fix internal electronic wear), followed by a mandatory throttle-body relearn to prevent high idle and driveability faults. Check whether the vehicle qualified for 13N03 or 16B32 coverage history.

Frequently asked questions
What does P2110 mean?
P2110 stands for "Throttle Actuator Control System - Forced Limited RPM." This code means the engine computer detected a serious problem in the electronic throttle (drive-by-wire) control system and, to protect the vehicle, has forced the engine into a reduced-power 'limp' mode that caps engine RPM. It is usually a reaction to another underlying throttle fault rather than the root cause itself, so other related codes are typically present. Because power is limited and acceleration is restricted, the car may be unsafe to drive in traffic and should be diagnosed promptly.
What are the most common causes of P2110?
The most common causes of P2110 are: Faulty throttle body / throttle actuator motor, Failed accelerator or throttle position sensor, Damaged, corroded, or loose throttle wiring/connectors, Dirty or carboned-up throttle plate, Related throttle-control fault codes (root cause) present, Low system voltage or poor grounds, PCM/ECM fault (rare). The specific cause varies by vehicle.
How much does it cost to fix P2110?
Repair costs for P2110 range from $30 to $700, depending on the vehicle and root cause.
