P2118 on Jeep
Throttle Actuator Control Motor Current Range/Performance
P2118 on Jeep vehicles indicates throttle actuator control motor current range/performance. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. The PCM detected that the electrical current drawn by the throttle actuator control motor is outside the expected range, indicating the motor is drawing too much or too little current to position the throttle correctly.
Common Causes of P2118
- •Failing throttle actuator motor (high current draw)
- •Binding throttle plate increasing motor load
- •High-resistance wiring/connectors
- •Carbon-fouled throttle body
- •Faulty PCM motor driver

- ETC Warning or Limp Mode - Read the DTC Before Buying a Throttle Body2011-2022
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.
