P2641 Fault Code

Torque Management Feedback Signal B

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

The Torque Management Feedback Signal B indicates that the engine control module (ECM) has detected a discrepancy in the torque management feedback signal that could affect engine performance. This is a part of the system that monitors the engine's torque output to ensure smooth and efficient operation.

What are the symptoms of the P2641 code?

Symptoms associated with P2641 may include:

• Engine performance issues, such as hesitation or stalling
• Irregular shifting of the transmission
• Decreased fuel efficiency
• Illuminated check engine light on the dashboard
• Reduced power output during acceleration.

What causes the P2641 code?

Common causes of this fault code include:

• Faulty or damaged wiring in the torque management circuit
• Issues with the throttle position sensor or accelerator pedal position sensor
• Malfunction in the engine control module (ECM)
• Problems with the transmission control module (TCM)
• A bad or failing torque converter.

How to fix P2641?

To address the P2641 fault code, you can follow these steps:

• Firstly, inspect the wiring and connectors in the torque management circuit for signs of damage or corrosion.
• Test the functionality of the throttle position sensor and accelerator pedal position sensor. If faulty, replace them.
• Check and test the engine control module for any fault codes or anomalies, and reprogram or replace it if necessary.
• Inspect the transmission control module and ensure it's functioning correctly.
• If all else fails, consider checking the torque converter for any mechanical issues.
