Definition: Throttle Actuator Control Motor Current Range/Performance
Severity: High
DIY Skill Level: Intermediate
Continue To Drive?: No
Estimated Repair Cost: $100 – $500

What Does The P2118 Mean?

The P2118 engine code indicates a malfunction in the operation of the Throttle Actuator Control System. This system is responsible for regulating the airflow into the engine by controlling the position of the throttle plate.

When the Powertrain Control Module (PCM) detects an issue with this system, such as voltage readings or performance outside the expected range, it triggers the P2118 code. This serves as a warning that there may be a problem with the current range and performance of the throttle actuator control motor.

It’s worth noting that the P2118 code is commonly found in various car brands, including Toyota, Lexus, Ford, KIA, and Hyundai. Additionally, it is often associated with codes P2102, P2103, P2107, P2108, P2110, P2111, and P2119, which relate to the throttle actuator control system.

Can You Still Drive With The Code P2118?

The P2118 engine code is considered a high severity level. This code directly affects the engine’s performance and drivability, so it should not be overlooked.

Driving with the P2118 code present can result in severe consequences. The engine may experience reduced power, poor acceleration, and potentially even stalling. These issues can compromise the safety of both the driver and the vehicle.

So, it is strongly advised not to continue driving with the P2118 code unresolved. Instead, it is essential to diagnose and repair the underlying problem as soon as possible. Promptly addressing this code will restore optimal throttle actuator control system function, ensuring the safe and efficient operation of your vehicle.

Signs Of The P2118 Code

Here are some common symptoms typically seen with this code:

Illuminated check engine light, TRAC OFF light
Limp mode (Fail-safe mode)
Reduced engine power or lack of acceleration
Engine stalling or rough idle
Hard starting
Little or no throttle response

Causes Of The P2118 Code

Here are some possible triggers:

Faulty throttle actuator control motor
Issues with the throttle body or throttle position sensor
Defective accelerator pedal position sensor
Wiring or electrical connection problems
Blown throttle actuator control motor’s fuse
Malfunctioning PCM

How Do I Diagnose And Fix The P2118 Code?

In this section, we will explore the essential tools and parts required for diagnosing and repairing the P2118 code, provide a step-by-step procedure to address the issue and discuss the level of DIY repair along with estimated costs.

Essential Tools and Parts

OBD-II scanner
Multimeter
Throttle actuator control motor replacement (if necessary)
Throttle body cleaner
Electrical contact cleaner
Wire connectors and electrical tape

Step-by-Step Procedure

Retrieve the trouble codes using an OBD-II scanner.
Check the throttle actuator control motor’s fuse on the junction box with a test light. Replace the fuse if it doesn’t work properly.
Inspect the throttle body and wiring connections for any signs of damage or loose connections. Clean/repair it if needed.
Check other components related to the Throttle Actuator Control System, such as the throttle position sensor and accelerator pedal position sensor, to ensure it works properly. Replace any faulty components if it’s bad.
Test the throttle actuator control motor’s voltage using a multimeter. If the voltage is outside the range in the vehicle’s repair manual, replace it with a new one.
Inspect the electrical wiring and connections associated with the throttle actuator control system. Clean/replace it if you see any dirt or damage.
Clear codes and test drive to ensure the issue has been resolved.
