This is the range for the most common fix, wheel speed sensor replacement. Which repair your car needs depends on a proper diagnosis.
The ABS computer lost a good speed signal from the left front wheel. That sensor sits behind the wheel and is exposed to road spray, brake dust and salt. On most makes this code means the sensor or its wire, though some use the number a little differently, so confirm with a scan tool or manual.
- Safe to drive?
- Short trips only
- Most common cause
- Dirty or damaged wheel speed sensor
Normal brakes usually still work, but without ABS help the wheels can lock in a hard stop, so leave extra room and brake early. Get it checked soon.

What you may notice
- ABS light on
- Traction control light on
- Stability control turned off
- Speedometer or cruise control acting up on some cars
Common causes, most likely first
- Dirty or damaged wheel speed sensor
- Broken or chafed sensor wire
- Worn wheel bearing or damaged tone ring
- Corroded connector
- Failed ABS module (less common)
Check this first
Look behind the left front wheel at the sensor and its wire for rust, dirt or damage, especially where the wire bends as you turn the wheel. Check the tone ring for packed grime or broken teeth, and use live wheel speeds to confirm.

- Ask for parts and labor listed separately, and for the hours.
- Ask for a written OK before any extra work. Many states require written authorization before repairs.

C0035 questions
Can I pass inspection with this code?
In many states a lit ABS light is an inspection failure. Rules differ, so check your local requirements, and plan on fixing it before the sticker is due.
Will the brakes still work?
Yes. The regular brakes keep working because they do not depend on the ABS. What you lose is the pulsing help that stops the wheels locking when you brake hard on a slippery road.
Is it just the sensor?
Often, but a worn wheel bearing or a chafed wire at the steering knuckle can cause the same code on the left front. The wheel area should be checked so the part you replace is the one that failed.
