Common Questions

What does C0035 mean and how does it affect my car?

C0035 indicates a malfunction in the wheel speed sensor circuit, crucial for the ABS system. If this code appears, your vehicle may experience reduced braking performance, increased stopping distances, and potential safety hazards. Ignoring it can lead to severe issues, especially in emergency braking situations.

What are the most common causes of C0035 and how much does it cost to fix?

The most common cause of C0035 is a faulty wheel speed sensor, which is typically priced between $100 and $300 for replacement. Wiring issues can also lead to this code, with repair costs ranging from $50 to $150. In rare cases, the ABS control module might need replacement, costing upwards of $400.

Can I drive my car with C0035 or should I stop immediately?

While you can technically drive with a C0035 code, it is not recommended as it compromises your vehicle's braking performance. If you notice the ABS light on, it’s advisable to address the issue as soon as possible to ensure your safety.

How can I diagnose C0035 myself using GeekOBD APP?

Using the GeekOBD APP, perform an OBD2 scan to retrieve the C0035 code. Look for any additional codes that may provide context. Check the freeze frame data for vehicle conditions when the code was triggered. You can also use the app to monitor the wheel speed sensor's output while driving.

What vehicles are most commonly affected by C0035?

Vehicles like the 2012-2018 Chevrolet Silverado and 2013-2016 GMC Sierra frequently experience the C0035 code due to their similar ABS system designs. It's essential to check for any recalls or technical service bulletins (TSBs) related to this issue.

How can I prevent C0035 from happening again?

To prevent C0035, regularly inspect the wheel speed sensors and their wiring for damage or corrosion during routine maintenance. Keeping the brake system clean from debris and ensuring proper installation of parts can also help avoid future issues.

What is C0035?

The DTC C0035 code indicates a malfunction in the wheel speed sensor circuit, which is crucial for the proper functioning of the Anti-lock Braking System (ABS). This code typically signifies that the powertrain control module (PCM) has detected an issue with the front wheel speed sensor circuit. The wheel speed sensor monitors the rotational speed of the wheel, providing vital information to the vehicle's ABS and traction control systems. When the sensor malfunctions or the circuit experiences problems, it can lead to critical safety issues, including compromised braking performance and loss of traction control. For car owners, this means that you may experience symptoms like the ABS warning light illuminating on your dashboard, or the vehicle may behave unpredictably under braking conditions. Ignoring this code can lead to further damage to the braking system, increased stopping distances, and a heightened risk of accidents. Therefore, it's essential to diagnose and repair this issue promptly. If you drive a vehicle like the 2015 Chevrolet Silverado, being aware of the potential for this DTC can help you maintain your vehicle’s safety and reliability.

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

Symptoms

Common symptoms when C0035 is present:

  • ABS warning light illuminates on the dashboard, indicating a fault in the brake system.
  • Vehicle experiences reduced braking efficiency or instability during sudden stops.
  • Traction control system may become unresponsive, leading to potential loss of control in slippery conditions.
  • Inconsistent speedometer readings, which may fluctuate or fail to operate altogether.
  • Increased stopping distances noted during normal driving conditions, putting the driver at risk.

Possible Causes

Most common causes of C0035 (ordered by frequency):

  1. Faulty wheel speed sensor (70% likelihood) - This is the most common cause, where the sensor itself may be damaged or worn out over time.
  2. Wiring issues (20% likelihood) - Damaged or corroded wires in the sensor circuit can lead to poor connectivity and signal disruption.
  3. Faulty ABS control module (5% likelihood) - A malfunctioning control module may misinterpret signals from the wheel speed sensor.
  4. Loose connections (3% likelihood) - Loose or corroded connectors can interrupt the flow of data from the sensor to the PCM.
  5. Physical obstructions (2% likelihood) - Debris or dirt blocking the sensor can lead to inaccurate readings.
