What Does C0287 Mean?
C0287 indicates a communication or signal fault in the delivered torque circuit between the powertrain control module (PCM) and the anti-lock brake system (ABS) or stability control module. The chassis control system relies on real-time engine torque data to properly manage traction control, stability control, and braking interventions. This code sets when the ABS/stability control module detects an implausible, missing, or corrupted torque signal from the engine control system.
Common Causes
35%
CAN bus communication fault between PCM and ABS module due to wiring damage, corrosion, or loose connections
25%
Faulty ABS/stability control module with internal communication processor failure
20%
PCM software calibration issue or corrupted torque calculation algorithm
12%
Throttle position sensor or accelerator pedal position sensor providing erratic data affecting torque calculations
8%
Low battery voltage or unstable power supply causing intermittent module communication
Diagnostic Steps
1
Step 1: Monitor live data for delivered torque signal, throttle position, and engine load using the scan tool. Compare actual engine torque values with expected torque calculations at various throttle positions and RPM levels to identify implausible readings
2
Step 2: Inspect CAN bus communication between PCM and ABS module using scan tool bi-directional controls. Check for active CAN bus errors, verify both modules are communicating, and test message transmission rates (should be consistent without dropouts)
3
Step 3: Perform visual inspection of all connectors at the PCM and ABS module for corrosion, bent pins, or moisture intrusion. Check CAN bus twisted pair wiring (typically CAN-High and CAN-Low) for shorts, opens, or damage, particularly in flex points and harness routing areas
4
Step 4: Using a digital multimeter, verify CAN bus resistance between CAN-High and CAN-Low terminals at the ABS module connector (should read approximately 60 ohms with modules disconnected, indicating proper termination resistors)
5
Step 5: Test battery voltage and charging system output with engine running (should be 13.5-14.5V). Check for voltage drops at module power and ground circuits under load conditions
6
Step 6: If all communication circuits test normal, perform PCM and ABS module software updates per manufacturer TSBs. If issue persists after updates, substitute test known-good modules to isolate faulty controller

The most common cause of C0287 (Delivered Torque Circuit) is: CAN bus communication fault between PCM and ABS module due to wiring damage, corrosion, or loose connections
Typical repair costs for C0287 range from $150 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is generally safe to drive with caution, but traction control and stability control systems may not function properly or may be disabled entirely. Avoid aggressive driving, slippery conditions, or emergency maneuvers until repaired, as electronic stability interventions may be unavailable.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C0287 to identify the root cause.
