What vehicles are most commonly affected by C0119?

C0119 is commonly found in vehicles such as the 2010-2019 Chevrolet Silverado and GMC Sierra, as well as various other GM models. Always check for any recalls or service bulletins related to the ABS system.

How can I prevent C0119 from happening again?

To prevent C0119, regularly inspect your vehicle's brake system, including sensors and wiring. Keeping the ABS system clean and free from dirt and moisture can also help maintain functionality.

What is C0119?

The Diagnostic Trouble Code (DTC) C0119 pertains to the Anti-lock Braking System (ABS) and indicates a malfunction in the right front wheel speed sensor or its circuit. This code is often encountered in vehicles like the 2010-2019 Chevrolet Silverado and GMC Sierra. When this code is triggered, it typically means that the ABS module is not receiving the proper signal from the right front wheel speed sensor. In practical terms, this can affect the vehicle's braking performance, particularly in slippery conditions where ABS is crucial for maintaining control. If left unaddressed, it may lead to a complete loss of ABS functionality, which can compromise safety. Drivers may notice the ABS warning light illuminating on the dashboard, and could experience issues such as longer stopping distances or reduced stability during braking. Understanding the implications of C0119 is vital for ensuring vehicle safety and performance, particularly for those who frequently drive in adverse weather conditions.

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

Symptoms

Common symptoms when C0119 is present:

  • The ABS warning light stays illuminated on the dashboard, indicating a malfunction in the ABS system.
  • You may notice that the brakes feel less responsive than usual, particularly during emergency stops.
  • Inconsistent brake performance, such as the brakes locking up or not engaging properly in slippery conditions.
  • A reduction in fuel efficiency can occur due to the extra strain on the braking system.
  • Unusual noises such as grinding or clicking when braking may also be present, indicating a potential mechanical failure.

Possible Causes

Most common causes of C0119 (ordered by frequency):

  1. The most common cause is a faulty right front wheel speed sensor, which has a likelihood of about 60%. This can occur due to wear and tear, exposure to road contaminants, or physical damage.
  2. Another possible cause is a damaged wiring harness or connector related to the wheel speed sensor, which can impede the signal transmission.
  3. Corrosion or moisture in the ABS module can also lead to issues, making regular inspections critical to prevent this.
  4. Less common but serious causes include internal faults within the ABS control module, which may require replacement.
  5. A rare cause could involve problems with the vehicle's onboard computer, leading to false readings and erroneous codes.
