What Does C0298 Mean?
C0298 indicates that the Anti-lock Brake System (ABS) control module has received a message from the Powertrain Control Module (PCM) indicating a traction control system malfunction or performance issue. This is a communication code where the PCM has detected a problem with its ability to control engine power output for traction control purposes. The chassis/ABS module is reporting what the powertrain module has communicated to it via the vehicle's CAN bus network.
Common Causes
35%
Wheel speed sensor failure or erratic signal causing PCM to disable traction control
25%
Throttle body or electronic throttle control system malfunction preventing traction control intervention
20%
CAN bus communication error between PCM and ABS module
15%
Brake system component failure affecting traction control operation
5%
PCM software calibration issue or internal module fault
Diagnostic Steps
1
Step 1: Review all active and pending DTCs in both the PCM and ABS modules to identify the root powertrain-related fault code that triggered this communication code (look for throttle control, wheel speed sensor, or engine torque management codes)
2
Step 2: Perform visual inspection of all four wheel speed sensors and wiring harnesses for damage, corrosion, or loose connections; check tone rings for damage or debris accumulation
3
Step 3: Using a multimeter, test wheel speed sensor resistance (typically 800-1400 ohms) and AC voltage output while rotating each wheel; compare readings across all four sensors for consistency
4
Step 4: Monitor live data stream for throttle position sensor, accelerator pedal position sensor, and electronic throttle body operation; verify smooth operation and proper voltage ranges (typically 0.5-4.5V) with no erratic signals
5
Step 5: Test CAN bus communication integrity between PCM and ABS module using bidirectional scan tool commands; verify both modules can communicate and command traction control functions
6
Step 6: Clear all codes, perform a test drive with traction control engagement (safe controlled loss of traction), and verify the primary powertrain fault code reappears to confirm repair of root cause

The most common cause of C0298 (Powertrain Indicated Traction Control Malfunction) is: Wheel speed sensor failure or erratic signal causing PCM to disable traction control
Typical repair costs for C0298 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive under normal conditions, but traction control and stability control systems will be disabled or operating in reduced mode. Exercise caution in wet, icy, or slippery conditions as the vehicle will not have electronic traction assistance and may be more prone to wheel spin or loss of control.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C0298 to identify the root cause.
