OBD Code P2108 - Throttle Actuator Control Module Performance
Is there smoke coming out of car’s tailpipe? Is
the engine stalling and not starting? Are you experiencing sudden drop in
acceleration with inappropriate throttle response? All these can be an
indication towards problematic throttle control system, which may lead to OBD
code P2108 getting stored in the Powertrain Control Module.
Learn More About OBD Error Code P2108
The Throttle Actuator Control System is controlled by the PCM by monitoring one or more throttle position sensors. According to the position of the throttle plate that is controlled by the Throttle Actuator Control Motors, the operation of the throttle body is determined. The accelerator pedal position sensor is monitored by the PCM to determine appropriate throttle response. The PCM does this by changing the current flow to the Throttle Actuator Control Motor which moves the throttle plate to the optimal position. Sometimes, the vehicle can also go into fail-safe or limp mode where the engine is held at idle or may not start at all.
What causes this problem with the Throttle Actuator Control Module Performance?
- Throttle actuator control module faulty
- TAC module wiring and harness damaged
- Poor connections to the TAC module
- Damaged throttle plate and throttle body
- Throttle position sensor failure
- Powertrain control module failure
Replace/Repair These Parts To Fix Code P2108
- Engine Control Module – ECM program faults can lead to misinterpretation of data causing wrong OBD codes to get stored in the system, leading to vehicle showing erratic behaviour. Thus, it is important to repair, replace and reprogram the ECM and its components.
- Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
- Throttle Position Sensor – It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. It may accelerate smoothly, but lack power. On the flip side, it may be that your car suddenly speeds up while you’re driving, even if you haven’t pressed the accelerator. If these symptoms occur, there's a good chance you've got a problem with the TPS. Thus, replace faulty TPS immediately.
- Throttle Actuator Connector – A Throttle Actuator is a component of the throttle control which helps to regulate throttle control in situations where additional throttle is needed suddenly or when there is a sudden drop in throttle needed. When there is a sudden release of the accelerator pedal, the throttle actuator serves to gradually slow engine speed rather than allowing a sudden drop. Replace faulty actuator connector now!
- Throttle Control Relay – In some cases a damaged throttle control relay will cause the engine to have issues with acceleration or cause a "stumbling" effect when the throttle is engaged by the driver. This can result in lack of performance and can be a safety concern if not inspected and repaired quickly. Not having full access to the throttle can lead to accidents and in the worst case, a stuck throttle. Buy new throttle control relay immediately.
- Accelerator Pedal Sensor – When the APP sensor is not functioning properly, it will also have problems with fuel efficiency. Besides monitoring and applying throttle pressure to the throttle body, it also helps to stabilize the throttle control. It's designed to take input from the driver, but steady the application of fuel pressure as it relays the information from the ECU to the throttle body of the vehicle. If the sensor is not able to transmit this information to the ECU correctly due to a loose wire, being worn out or have broken entirely, you'll notice a huge difference in fuel economy. Thus, replace faulty APP sensor from us today!

Easy Diagnosis Of Engine Error OBD Code P2108
If you want to easily diagnose this P2108 fault code, then all you have to do is to follow the steps which are mentioned below:
- As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
- After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
- Note down this information as it can clearly help for further diagnosis.
- After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
- He will know that an intermittent condition persist, if the code does not return instantly.
- But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the throttle position sensor, accelerator pedal position sensor and the actuator control module.
- If any of the component is damaged, the mechanic will replace them quickly.
- Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.
Common Mistakes When Diagnosing the P2108 Code
- Some issues related to the throttle assembly
- PCM and ECU faults
- Faults in the wiring and harness
- Failure in the throttle actuator control module
