What vehicles are most commonly affected by C0037?

DTC C0037 is commonly found in vehicles like the 2013-2018 Chevrolet Silverado, 2015-2019 Ford F-150, and various models from manufacturers like Honda and Toyota. Always check for any recalls or Technical Service Bulletins (TSBs) related to this code.

How can I prevent C0037 from happening again?

Regular maintenance, such as inspecting wheel speed sensors and wiring during routine service, can help prevent C0037. Ensure that your vehicle stays clean and free from debris that can damage these components.

What is C0037?

The DTC code C0037 refers to a wheel speed sensor circuit range/performance problem, typically associated with the ABS (Anti-lock Braking System). This code is prevalent in various makes and models, including the 2013-2018 Chevrolet Silverado and 2015-2019 Ford F-150. When this code is triggered, it indicates that the wheel speed sensor is not providing accurate data to the vehicle's control module, which can lead to issues with the ABS system's functionality. This means that the vehicle might not be able to properly modulate brake pressure during sudden stops, increasing the risk of skidding or losing control, especially in slippery conditions. Drivers may experience symptoms such as the ABS warning light activating on the dashboard, decreased traction control, or even erratic braking behavior. Understanding the implications of DTC C0037 is crucial for ensuring your vehicle remains safe to drive. If left unaddressed, it can lead to more severe braking issues and costly repairs down the road. Therefore, if you encounter this code, it is essential to take action promptly.

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

Symptoms

Common symptoms when C0037 is present:

  • ABS warning light illuminates continuously on the dashboard, indicating a malfunction in the abs system.
  • Brake performance feels inconsistent, with potential for the brakes to engage erratically during hard stops.
  • Traction control system may deactivate, leading to reduced stability in slippery conditions, such as rain or snow.
  • You might notice a grinding noise when braking, which can imply an underlying issue with the wheel speed sensors.
  • Increased stopping distance, due to the lack of ABS function, leading to potential accidents.

Possible Causes

Most common causes of C0037 (ordered by frequency):

  1. The most common cause of DTC C0037 is a faulty wheel speed sensor, which occurs in approximately 60% of cases. This sensor can become damaged from road debris or wear and tear.
  2. Another common cause is damaged wiring or connectors within the ABS system, which can lead to intermittent signals. This often happens due to corrosion or physical damage, accounting for about 25% of issues.
  3. A malfunctioning ABS control module can also trigger this code, though it is less frequent, making up around 10% of cases. If the control module fails, it may not interpret signals accurately.
  4. In rare cases, this code can be triggered by a problem with the brake system itself, such as a stuck caliper or brake line leak.
  5. Lastly, low battery voltage or poor electrical connections can sometimes lead to erroneous readings from the wheel speed sensors.
