• Solutions

The P2108 fault code indicates a problem with the Throttle Actuator Control Module's performance. This module is crucial for regulating the throttle position based on input from the engine control module (ECM) and driver commands. When the module experiences issues, it can lead to poor engine performance and responsiveness.

What are the symptoms of the P2108 code?

Symptoms associated with P2108 may include:

• Engine stalling or poor acceleration
• Display of the Check Engine Light (CEL)
• Reduced power or limp mode activation
• Unusual idle behavior or rev fluctuations
• Difficulty in maintaining a steady speed

What causes the P2108 code?

Common causes of the P2108 code include:

• Faulty throttle actuator control module
• Wiring issues or short circuits in the throttle control circuit
• Faulty throttle position sensor (TPS)
• ECM issues or malfunctions
• Physical obstructions in the throttle plate or actuator

How to fix P2108?

To resolve the P2108 code, consider the following steps:

• Inspect and repair any damaged wiring or connectors in the throttle control system.
• Replace a faulty throttle actuator control module or throttle position sensor if diagnosed.
• Clean the throttle body to remove any obstructions or carbon buildup.
• Reprogram or replace the ECM if it is found to be malfunctioning.
• Clear the fault codes and perform a test drive to ensure the issue is resolved.
