[SOLVED] P2118 Code: Fixing Throttle Control Motor Performance Issues

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2118 fault code. This code indicates a problem with the Electronic Throttle Control System (ETCS) Fuse, faulty battery, loose or damaged battery terminals, faulty Throttle with Motor Body Assembly, or faulty Engine Control Module (ECM).

The importance of repairing this issue lies in the fact that it can cause poor acceleration, stalling, or even prevent the vehicle from starting. The repair difficulty is moderate, and it takes around 1.0 hour to fix. To interpret the fault code, you need to check the possible causes listed above and visually inspect the related wiring harness and connectors.

Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2118 fault code.

Here are the symptoms to look out for:

  • The P2118 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include the engine stalling or idling roughly, the throttle not responding correctly, the vehicle going into limp mode, and the accelerator pedal feeling unresponsive.
  • Additionally, the vehicle may experience reduced power and acceleration, and the engine may not start at all.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2118, including issues with the ETCS fuse, battery, terminals, throttle assembly, and ECM.

  • The automobile fault code P2118 can be caused by several factors.
  • These include a blown Electronic Throttle Control System (ETCS) fuse, a faulty battery, loose or damaged battery terminals, a faulty Throttle with Motor Body Assembly, and a faulty Engine Control Module (ECM).
  • It is important to identify the root cause of the fault code to ensure proper and effective repairs are made.

To fix the p2118 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2118, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2118 indicates a problem with the throttle actuator control motor. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2118 code is related to the Electronic Throttle Control System (ETCS). It indicates that the voltage supplied to the ETCS is low, causing the system to become unstable.

When the voltage drops below 4V, the Engine Control Module (ECM) cuts the current to the throttle actuator.

This results in the MIL (Malfunction Indicator Lamp) illuminating and the ECM storing the Diagnostic Trouble Code (DTC). To fix the issue, the power supply circuit must be repaired and the ignition switch turned off before restarting the actuator.

What are the possible causes of the P2118 fault code in an automobile?

If you’re experiencing the P2118 fault code in your automobile, the engine light or service engine soon warning light may turn on. The possible causes of this fault code include a faulty battery, loose or damaged battery terminals, a faulty throttle with motor body assembly, a faulty engine control module (ECM), or an electronic throttle control system (ETCS) fuse. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P2118 fault code?

If you’re experiencing the P2118 fault code, indicated by the engine light or service engine soon warning light turning on, there are a few possible causes to consider. These include a faulty battery, loose or damaged battery terminals, a faulty throttle with motor body assembly, a faulty engine control module (ECM), or an issue with the electronic throttle control system (ETCS) fuse. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the steps to take when checking for damaged components and corroded connector’s pins to fix the P2118 fault code?

If you’re experiencing the P2118 fault code, start by checking the possible causes, including the ETCS fuse, battery, terminals, throttle assembly, and ECM. Then, visually inspect the wiring harness and connectors for any damage or corrosion on the pins. Look for broken, bent, or pushed out pins, and replace any damaged components as necessary.

p2118 error fault code explained

If your engine light is on due to the P2118 fault code, check the ETCS fuse, battery, and terminals for faults. Inspect the wiring harness and connectors for damage, and check for broken or corroded pins. Also, check the throttle and ECM for faults.
