Regarding Hyundai vehicles, the Code P2118 is a common diagnostic trouble code (DTC) that indicates a potential problem with the Throttle Actuator Control Motor Circuit. This code is triggered when the Electronic Throttle Control (ETC) motor control duty value is over 80% and 5 seconds, and the ECM recognizes it as a throttle valve sticking. One must understand the possible causes and potential solutions to fix the issue. To help with this, we have compiled a list of causes and solutions for the Hyundai Code P2118.

Causes and Solutions for Hyundai Code P2118
| Cause | Solution |
|---|---|
| Poor connection | Check for any disconnected wiring and replace if needed. |
| Short to ground in ETS motor circuit | Replace the wiring and connectors in the circuit. |
| Faulty ETS motor | Replace the ETS motor. |
| Faulty PCM | Replace the PCM. |
Understanding the Hyundai Code P2118 is essential for any Hyundai owner or technician. This code indicates an issue with the Throttle Actuator Control Motor Circuit, which may be caused by a poor connection, short to ground in the ETS motor circuit, faulty ETS motor, or faulty PCM. For those experiencing this issue, several solutions are available to help identify and repair the problem. We have compiled a list of causes and solutions for the Hyundai Code P2118 to help you get started.
Poor Connection
When diagnosing the Hyundai Code P2118, it is important to first check for any disconnected wiring. A poor connection can lead to a false ETC motor control duty value, triggering the code. To fix this issue, locate any separate wiring and replace or reconnect as needed.
Short To Ground In ETS Motor Circuit
If the initial check reveals no disconnected wiring, the next step is to check the ETS motor circuit for any shorts to the ground. These shorts can cause the ETC motor control duty value to exceed the 80% and 5-second mark, triggering the code. To fix this issue, replace the wiring and connectors in the circuit.

Faulty ETS Motor
In some cases, the ETS motor itself may be faulty. If this is the case, the ETC motor control duty value will not be resolved, and the code will remain. To fix this issue, replace the ETS motor with a new one.
Faulty PCM
Finally, the PCM itself may be faulty and need to be replaced. This is the last solution that should be attempted, as the PCM is an expensive component. If the PCM is indeed faulty, replacing it should resolve the issue.
Conclusion
Hyundai Code P2118 is a common diagnostic trouble code (DTC) that indicates a potential problem with the Throttle Actuator Control Motor Circuit. One must understand the possible causes and potential solutions to prevent and repair this issue. This article discusses the main causes and solutions for the Hyundai Code P2118, including poor connection, short to ground in the ETS motor circuit, faulty ETS motor, and faulty PCM. With this information, Hyundai owners and technicians should be able to identify and fix the issue.
