Q: What does code P2641 mean?

Torque Management Feedback Signal 'B'. P2641 indicates that the powertrain control module (PCM) has detected an implausible or out-of-range signal on the torque management feedback circuit designated as 'B'. The PCM uses this feedback to confirm that the torque reduction request—typically from the traction control or stability control system—is being carried out correctly by the engine and transmission. When the signal does not match expected values, the PCM sets this code and may disable torque management functions.
