P2110 on Jeep
Throttle Actuator Control System - Forced Limited RPM
P2110 on Jeep vehicles indicates throttle actuator control system - forced limited rpm. Au7o has documented this code across 2 Jeep models — most commonly on Grand Cherokee, Wrangler. 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. Typical repair costs on Jeep range from $50 to $650, depending on the specific model and root cause.
Common Causes of P2110
- •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)
P2110 on Jeep by Model
Jeep Grand Cherokee(1 issue)
- Electronic Throttle Control (ETC) Warning Light and Throttle Body Failure Causing Limp Mode (3.6L Pentastar)2011-2022
The amber lightning-bolt-in-parentheses 'Electronic Throttle Control' (ETC) warning is one of the most frequently reported faults on Pentastar-era Grand Cherokees. A contaminated or worn electronic throttle body, a failing throttle position sensor, or a corroded throttle-body connector causes the PCM to drop the engine into a reduced-power 'limp' state, with sudden loss of acceleration, surging, rough idle, or stalling. Owners frequently report the light clearing temporarily after a restart, then returning. Some cases are actually triggered by an out-of-range oil-temperature sensor or a stuck thermostat rather than the throttle body itself, so diagnosis before parts replacement is important.
Jeep Wrangler(1 issue)
- Electronic Throttle Control Limp Mode — Red Lightning Bolt (Throttle Body / TPS / APP Sensor)2007-2018
JK Wranglers use a drive-by-wire electronic throttle. A fault in the electronic throttle body, the integrated throttle position sensor (TPS), the accelerator pedal position (APP) sensor, or their wiring/connectors triggers the red lightning-bolt warning, often together with the traction-control light. The PCM drops the engine into limp mode — reduced power, rough/erratic idle, and capped RPM — to protect the engine. Heat-soak and intermittent connector contact at the throttle body are common triggers, so the fault frequently comes and goes. It is one of the most-searched JK driveability complaints.

What does P2110 mean on Jeep?▼
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. On Jeep specifically, this code is documented across 2 models.
