You can use the GeekOBD APP to scan your vehicle's OBD2 system, retrieve DTCs, and view real-time data. Look specifically for wheel speed sensor readings to help identify the problem.
What vehicles are most commonly affected by C0190?
Models like the 2015-2020 Chevrolet Silverado, GMC Sierra, and others from this range are frequently affected by DTC C0190 due to similar ABS systems.
How can I prevent C0190 from happening again?
Regular maintenance, including inspections of your ABS system, wiring, and sensors, can help prevent C0190 from occurring again. Keeping your vehicle clean and free of corrosion is also essential.
What is C0190?
The diagnostic trouble code (DTC) C0190 indicates a malfunction in the vehicle's anti-lock brake system (ABS) or electronic brake control system. This code is particularly common in 2015-2020 Chevrolet and GMC models, where it can signify issues with the wheel speed sensors or the ABS control module. When C0190 is triggered, the vehicle's stability and braking performance may be compromised, which poses a safety risk. The ABS system is crucial for maintaining control during emergency braking situations, and any faults can lead to longer stopping distances or unresponsive brakes. Drivers may notice the ABS warning light illuminated on the dashboard, which serves as an alert to the driver that the system is not functioning correctly. It's essential to address this code promptly to ensure the vehicle's braking systems operate efficiently and safely. Ignoring this issue can lead to more severe problems, including complete ABS failure, which can be costly to repair.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0190 is present:
- The ABS warning light illuminates on the dashboard, indicating a malfunction in the braking system.
- Drivers may experience reduced braking performance, particularly during sudden stops or hard braking situations.
- Unusual noises such as grinding or clicking can occur when applying the brakes, signaling a potential fault in the brake system.
- The brake pedal may feel different, either becoming spongy or hard, which can affect stopping power.
- In some cases, the vehicle may exhibit erratic ABS operation, where the system engages and disengages unexpectedly.
Possible Causes
Most common causes of C0190 (ordered by frequency):
- The most common cause of C0190 is a faulty wheel speed sensor, which is responsible for providing data to the ABS system. This issue accounts for approximately 60% of cases.
- Another frequent culprit is a malfunctioning ABS control module, which can lead to the entire system failing to operate correctly.
- Corroded or damaged wiring and connectors related to the ABS system can also trigger this code. Regular inspections can help prevent this issue.
- Less common, but serious, is a hydraulic pump failure within the ABS module that can lead to complete brake system failure.
- A rare cause might include software issues or glitches within the vehicle's onboard computer systems, which may require a software update or reprogramming.
