Using the GeekOBD APP, you can scan for DTCs, review freeze-frame data, and check for any other related codes. Look for unusual readings from your wheel speed sensors that may indicate faults.

What vehicles are most commonly affected by C0731?

C0731 is frequently reported in Ford F-150 (2015-2020), Toyota Camry (2013-2019), and Honda Accord (2014-2019). Check for any recalls or technical service bulletins related to the traction control system for these models.

How can I prevent C0731 from happening again?

Regular maintenance, including checking wiring and connectors for wear and tear, can help prevent C0731. Additionally, ensuring your brake system is functioning correctly and keeping the vehicle's software updated can reduce risks.

What is C0731?

The diagnostic trouble code (DTC) C0731 indicates a malfunction in the traction control system, specifically related to the traction control module. This code can arise when the vehicle's onboard computer detects an issue with the signals sent from the traction control sensors. In simpler terms, the traction control system is designed to prevent wheel slip during acceleration by adjusting engine power or applying brakes to specific wheels. When a problem is detected, it may lead to reduced traction, especially under slippery conditions such as rain or snow, resulting in the traction control light illuminating on your dashboard. Notably, C0731 is commonly reported in vehicles like the Ford F-150 (2015-2020), Toyota Camry (2013-2019), and Honda Accord (2014-2019). Ignoring this code can lead to compromised vehicle safety, especially during adverse weather conditions, as the system may not perform effectively when needed. It's important to address this issue promptly to ensure your vehicle operates safely and efficiently.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0731 is present:

  • The traction control light illuminates on the dashboard, signaling a potential issue with the system.
  • You may experience a noticeable decrease in acceleration, especially on wet or icy roads, causing hesitation in power delivery.
  • Drivers often report a reduction in fuel economy, sometimes by as much as 10-15%, attributed to the traction control system working harder to maintain stability.
  • Unusual noises during acceleration, such as grinding or clunking, may occur as the system attempts to engage.
  • The vehicle may fail to respond appropriately when traction is lost, which can be alarming during adverse driving conditions.

Possible Causes

Most common causes of C0731 (ordered by frequency):

  1. A faulty traction control module is the most common cause, occurring in about 40% of C0731 cases. This module is responsible for processing inputs from various sensors, and if it fails, it can disrupt the entire system's functionality.
  2. Wiring issues or damaged connectors contribute to about 25% of C0731 occurrences. Corrosion or frayed wires can interrupt signals between components.
  3. Sensor malfunction, particularly in the wheel speed sensors, is another common cause, accounting for approximately 20%. These sensors monitor wheel rotation and can fail or become misaligned.
  4. Less common but serious causes include brake system failures, which can impact the traction control system's effectiveness and may require immediate professional attention.
  5. In rare cases, software glitches in the vehicle's control module can lead to C0731 codes, requiring a software update or reprogramming.
