What does C0035 mean?
C0035 is defined as “Right Front Wheel Speed Sensor Supply”. This code indicates a problem with one of the ABS wheel speed sensors, the sensor ring or the ABS unit. Normal braking still works, but ABS and ESP may be disabled.
Drive gently and only as far as you need to; have it checked as soon as possible.
Symptoms
- ABS, ESP and traction control lights come on
- Wheels locking under hard braking
- On some cars, the speedometer behaving erratically
Common causes
- Faulty wheel speed sensor or a dirty sensor tip
- Broken/rusted sensor ring (ABS reluctor ring)
- Broken sensor wire (from suspension movement)
- Excessive wheel bearing play
How to diagnose it
- Identify which wheel's sensor is faulty.
- In live data, check that all wheel speeds match at low speed.
- Check the sensor wire and connector, and clean the sensor tip.
- Inspect the ring for cracks and rust.
How to fix it
- Replace the faulty sensor.
- Replace a damaged ring or the bearing with the integrated ring.
- Clear the code and confirm the lights go out on a road test.
