What vehicles are most commonly affected by C0651?

The C0651 code is frequently reported in models like the 2014-2018 Chevrolet Silverado, 2016-2019 Ford Explorer, and other vehicles equipped with electronic stability control systems. Always check for recalls or technical service bulletins related to these issues.

How can I prevent C0651 from happening again?

Regular maintenance, including inspections of the steering system, ensuring correct installation of parts after repairs, and recalibrating the steering angle sensor whenever necessary, can help prevent the C0651 code from reappearing.

What is C0651?

The DTC C0651 code indicates a malfunction related to the vehicle's steering angle sensor, which is crucial for stability control systems. This code often appears in vehicles that are equipped with advanced driver-assistance systems (ADAS). When the C0651 code triggers, it signifies that the steering angle sensor is not providing accurate data to the vehicle's computer system. This can lead to various issues, including impaired handling and the potential failure of traction control systems. If not addressed promptly, the vehicle may exhibit erratic steering behavior, which can compromise safety. Many owners of vehicles like the 2014-2018 Chevrolet Silverado or 2016-2019 Ford Explorer report experiencing this code, particularly after making modifications to the steering system or after a collision. The code can also activate the check engine light, alerting drivers to a potential issue. Ignoring this code may lead to further complications with the ABS (anti-lock braking system) and electronic stability control, making it vital for vehicle owners to address the problem as soon as possible. Diagnostic tools such as the GeekOBD APP can help identify the specific fault and guide you through the repair process, ensuring your vehicle remains safe and reliable.

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

Symptoms

Common symptoms when C0651 is present:

  • The check engine light remains illuminated, indicating a fault in the vehicle's systems.
  • Steering feels unresponsive or inaccurate, making it difficult to maintain control during turns.
  • The stability control light flashes intermittently, suggesting that the vehicle's stability systems are not functioning properly.
  • Reduced fuel efficiency may occur, as the vehicle compensates for steering issues.
  • Increased tire wear might be noticeable, as improper alignment affects how tires make contact with the road.

Possible Causes

Most common causes of C0651 (ordered by frequency):

  1. The most common cause of the C0651 code is a faulty steering angle sensor, with a likelihood of about 70%. This can occur due to wear and tear or physical damage.
  2. Another possible cause is incorrect calibration of the steering angle sensor after repairs or replacements, which can happen during routine maintenance or collision repairs.
  3. A wiring issue, such as damaged or corroded connections, can lead to signal loss from the steering angle sensor, which is a less common cause but still significant.
  4. A malfunctioning ABS module could also trigger this code, impacting how the vehicle's braking system interacts with stability control.
  5. Although rare, a failing electronic control unit (ECU) can lead to inaccurate data being reported from the steering angle sensor, causing the C0651 code to appear.
