P2544 Ford Code - Torque Management Request Input Signal 'A'
Quick Answer
To improve shift feel, the Transmission Control Module (TCM) may request that the Engine Control Module (ECM) reduce engine torque during shift events. Common causes include Faulty Engine Control Module (ECM), Faulty Transmission Control Module (TCM), Engine Control Module (ECM) software update. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2544 Ford Description
The torque reduction request is sent to the ECM through a communication network called the controller area network (CAN). Two circuits are used to communicate CAN data between the ECM and TCM.
A fault in the CAN will not cause the ECM to set the Diagnostic Trouble Codes (DTC). If a CAN fault occurs, other DTCs will set before this code.
The ECM set the OBDII code when the TCM receives a torque reduction failure message from the ECM.
What are the Possible Causes of the DTC P2544 Ford?
- Faulty Engine Control Module (ECM)
- Faulty Transmission Control Module (TCM)
- Engine Control Module (ECM) software update
- Transmission Control Module (TCM) software update
- Engine Control Module (ECM) harness is open or shorted
- Engine Control Module (ECM) circuit poor electrical connection

This code does not reset itself after fault is gone. It must be manually cleared. It occurred when I was running engine to reduce fuel line pressure before changing fuel filter on a 2005 500 sedan.

I'm working on an 05 500 just change the spark plugs so I had to remove the whole plenum upon putting it back I'm getting the p 2544 code. The engine feels fine and it runs great for about 40 minutes and then it kicks on and tells me check engine check transmission I have an OBD2 so I'm not real sure on what to check first are there any commonly known areas that I need to focus on? Tomorrow I'm going to comb-pick over the entire setup. Any advice would be appreciated. My thought is the throttle positioning sensor? Am I Hot or Cold? lol
-
The only information I got is that on some 2005 Ford Five Hundred, the P2544 code sets when there is a Powertrain Control Module (PCM) and Transmission Control Module (TCM) calibration problem. It's possible that you may have lost the PCM or TCM calibration during the repair. You may have to reprogram the PCM and TCM to repair the problem.
