To diagnose C0920 using the GeekOBD APP, connect the app to your vehicle's OBD2 port, retrieve the trouble codes, and analyze the freeze frame data to identify when the fault occurred.

What vehicles are most commonly affected by C0920?

Commonly affected vehicles include the 2015-2018 Jeep Cherokee and the 2013-2016 Ford Escape, among others. These models often experience issues with the TCS, leading to the C0920 code.

How can I prevent C0920 from happening again?

Regular maintenance, including checking the wiring and connectors associated with the TCS, can help prevent future occurrences. Keeping your vehicle's software updated is also crucial.

What is C0920?

DTC C0920 refers to a malfunction related to the Traction Control System (TCS) in your vehicle. This code indicates that there is an issue with the TCS that could affect your vehicle's ability to maintain traction on slippery surfaces. The TCS is crucial for preventing wheel spin during acceleration, especially in adverse weather conditions. When this code is triggered, it means that the system has detected an abnormality in its operation, which could stem from faulty sensors, wiring issues, or problems with the control module itself. As a result, you may notice that your vehicle struggles for grip when accelerating on wet or icy roads. In addition, the traction control warning light may illuminate on your dashboard, indicating that the system is disabled. If left unresolved, C0920 could lead to further complications, such as reduced vehicle stability and safety concerns when driving in inclement weather. Commonly found in vehicles like the 2015-2018 Jeep Cherokee and the 2013-2016 Ford Escape, addressing this issue promptly is vital for preserving the functionality of your vehicle's safety features.

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

Symptoms

Common symptoms when C0920 is present:

  • The traction control warning light illuminates consistently, indicating a malfunction in the system.
  • You may experience wheel spin during acceleration, especially on wet or slippery roads, leading to difficulty in maintaining control.
  • The vehicle may exhibit reduced stability during cornering, potentially causing it to slide or lose grip.
  • In some cases, the engine may hesitate or misfire during acceleration, which can be alarming for drivers.
  • A noticeable increase in tire wear may occur if the traction control system is not working correctly, as it may allow excessive wheel spin.

Possible Causes

Most common causes of C0920 (ordered by frequency):

  1. The most common cause of DTC C0920 is a faulty wheel speed sensor, accounting for about 40% of cases. This sensor monitors the rotation speed of each wheel and sends signals to the TCS.
  2. Another frequent issue is damaged wiring or poor connections in the TCS circuit, leading to intermittent faults. This typically represents around 30% of the causes.
  3. Faulty control modules or software glitches can also trigger this code, representing about 20% of cases. Regular updates can help mitigate this.
  4. Less common but serious causes include malfunctioning ABS (Anti-lock Braking System) components, which may require more extensive repairs.
  5. In rare instances, issues with the vehicle's Engine Control Module (ECM) can cause the C0920 code, though this is the least likely cause.
