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. The electronic throttle body accumulates carbon buildup that restricts airflow at idle, and the throttle position sensor can drift out of calibration. The 2.4L 4-cylinder is most commonly affected but the 3.6L V6 is also susceptible. 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
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.

Jeep Grand Cherokee · 2011–2022
The electronic-throttle-control warning lamp and reduced-power or limp mode are protective responses, not a diagnosis that the throttle body has failed. Depending on the stored DTC and application, the factory path may lead to a stuck or contaminated throttle plate, throttle motor or position-sensor response, accelerator-pedal sensors, a five-volt supply fault, damaged wiring or terminals, or a PCM issue. The old card's thermostat shopping claim is not part of the cited ETC diagnostic path, and a throttle body should not be ordered from the warning lamp alone.
Common Symptoms
- Electronic throttle control warning lamp
- Reduced engine output, limited RPM, or limp mode
- Poor or absent accelerator response
- One or more throttle, pedal, voltage-supply, or actuator DTCs
How to Fix
Before clearing anything, record every PCM DTC, pending code, freeze-frame value, battery voltage, temperature, and the exact conditions under which reduced power occurred. Diagnose prerequisite five-volt-supply, throttle-position, accelerator-pedal, or other active faults in the order specified by the current factory procedure for that VIN and engine. For a P2111-style fault, inspect the throttle plate for binding or foreign material and run the scan-tool throttle-follower test, then test the motor circuits, connector terminals, and wiring as directed. For a pedal-correlation code such as P2138, follow the accelerator-pedal sensor and circuit procedure instead. Replace and relearn a throttle body only when the applicable test condemns it; do not buy a thermostat as an ETC rule-out part.
Owner tips & cautions
- WarningAn ETC lamp does not prove the throttle body failed. Save the codes and freeze-frame data before clearing them or disconnecting the battery.
- TipAsk the shop to name the exact DTC and the failed factory test step before approving any throttle-body, pedal, wiring, or PCM part.

Dodge Dart · 2013–2016
Darts across all engine options experience random stalling at idle, particularly when coming to a stop or sitting at traffic lights. The issue stems from a combination of electronic throttle body carbon buildup and PCM software calibration problems. The 2.0L and 2.4L engines are most commonly affected. Several TSBs have been issued addressing idle quality.
Common Symptoms
- Engine stalls when coming to a stop
- Rough or fluctuating idle RPM
- Engine dies at traffic lights or in drive-through
- Momentary loss of power steering when engine stalls
- Check engine light may or may not illuminate
How to Fix
Start with a throttle body cleaning using CRC throttle body cleaner — remove the intake hose and clean the butterfly valve and bore. Then visit a dealer for the latest PCM flash update (TSB 18-034-14 REV.B or newer). If stalling persists after both steps, replace the electronic throttle body assembly (Mopar 04891585AC for 2.4L). Perform idle relearn after any throttle body service.

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.
Which vehicles are affected by P2110?
Au7o has documented P2110 across 7 vehicle models from 4 manufacturers: Chrysler, Dodge, Ford, Jeep.
