P2545Torque Management Request Input Signal 'A' Range/Performance

P2545 indicates that the powertrain control module (PCM) has detected an out-of-range or erratic signal from the torque management request input 'A' circuit, which is typically a driver-requested torque reduction input such as a tow/haul mode switch or a stability control torque request. The PCM monitors the voltage or data from this input and sets the code when the signal falls outside the expected range for a calibrated time or performance criteria.
