P2106 Fault Code

Throttle Actuator Control System Forced Limited Power

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2106 fault code indicates that the throttle actuator control system is operating in a limited power mode. This typically occurs when the Engine Control Module (ECM) detects a malfunction in the throttle system that could potentially affect vehicle safety. It prompts the system to limit power to avoid further damage and ensure safe operation.

What are the symptoms of the P2106 code?

Symptoms associated with a P2106 code can include:

• Decreased engine power or acceleration
• Engine stalling or hesitation during acceleration
• Illuminated check engine light (CEL)
• Erratic or unresponsive throttle pedal behavior
• Unusual engine idle or engine revving issues

What causes the P2106 code?

Common causes of the P2106 code may include:

• Faulty throttle body or throttle position sensor
• Wiring issues or connector problems, such as corrosion or short circuits
• Malfunctioning ECM or software issues
• Vacuum leaks affecting throttle response
• Mechanical problems in the throttle linkage or assembly

How to fix P2106?

To address the P2106 code, the following steps should be taken:

1. Perform a diagnostic scan to confirm the P2106 fault code and check for any related trouble codes.
2. Inspect the throttle body and throttle position sensor for signs of damage or wear.
3. Check all wiring and connectors for issues like corrosion, loose connections, or frays.
4. Clear the fault codes and conduct a road test to see if the code returns.
5. If necessary, replace any faulty components such as the throttle body or sensors and re-test the system.
