Frequently Asked Questions

Can I drive with error code C0035?
You can drive short distances, but your ABS system will be disabled. This means your wheels may lock up during hard braking, increasing stopping distances and reducing control. Get it fixed as soon as possible for safety.
What causes wheel speed sensor failure?
Common causes include corrosion from road salt, physical damage from debris, worn reluctor rings, damaged wiring, or normal wear after high mileage. Environmental factors like moisture and dirt buildup can also cause sensor malfunctions.
How much does it cost to replace a wheel speed sensor?
DIY replacement typically costs $30-80 for the sensor plus your time. Professional repair ranges from $150-300 including labor. The sensor itself is relatively inexpensive, but labor costs vary by vehicle accessibility.
Will error code C0035 cause my car to fail inspection?
Yes, in most states an illuminated ABS warning light will cause your vehicle to fail safety inspection. The ABS system is considered a critical safety component that must be functioning properly.
How often should wheel speed sensors be replaced?
Wheel speed sensors typically last 100,000-150,000 miles under normal conditions. However, harsh driving conditions, road salt exposure, and poor maintenance can reduce their lifespan significantly.
