What Does P2545 Mean?
The torque management request signal is present but the values are not within the expected range for operating conditions. The PCM detects the signal doesn't correlate properly with commanded actions or other system parameters.
Common Causes
30%
TCM calibration mismatch or outdated software causing incorrect signal values
25%
Failing transmission control module sending erratic torque requests
20%
Communication interference or noise on signal circuit
15%
Poor ground connection causing signal reference issues
10%
PCM misinterpreting valid signal due to internal fault
Diagnostic Steps
1
Step 1: Monitor torque management request values with scan tool during various operating conditions
2
Step 2: Compare actual torque request values to expected ranges in service information
3
Step 3: Check for technical service bulletins related to torque management and module calibrations
4
Step 4: Verify all control module software versions are current and compatible
5
Step 5: Inspect control module grounds and power supplies for proper voltage and resistance
Estimated Repair Cost
$100 - $1,500
Parts + labor, varies by vehicle and location
The torque management request signal is present but the values are not within the expected range for operating conditions. The PCM detects the signal doesn't correlate properly with commanded actions or other system parameters.
The most common cause of P2545 (Torque Management Request Input Signal "A" Range/Performance) is: TCM calibration mismatch or outdated software causing incorrect signal values
Typical repair costs for P2545 range from $100 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in abnormal shift feel or timing, potentially causing harsh engagement. Can typically be driven but may accelerate transmission wear if prolonged.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2545 to identify the root cause.
