Code P2644 Dodge Description
The P2644 diagnostic trouble code for Dodge vehicles indicates an issue with the Torque Management Feedback Signal 'B' being too high. This code is related to the engine control module (ECM) monitoring the feedback signal from the torque management system, which is responsible for regulating engine power output based on various factors such as throttle input, vehicle speed, and load conditions. When the signal is detected to be higher than the specified threshold, the ECM triggers the P2644 code, indicating that there is a malfunction in the torque management system that needs attention.
Common Causes of P2644 Dodge
- Faulty torque management sensor
- Wiring issues or electrical connection problems
- Malfunctioning torque management system components
- ECM software glitch or calibration error
- Engine overheating causing sensor malfunction
Symptoms of P2644 Dodge
- Reduced engine power
- Erratic shifting
- Rough idling
- Stalling
