C0035 on Subaru
Left Front Wheel Speed Sensor Circuit
C0035 on Subaru vehicles indicates left front wheel speed sensor circuit. Au7o has documented this code across 1 Subaru model — most commonly on Crosstrek. This chassis code indicates a fault in the left front wheel speed sensor circuit. Each wheel has a speed sensor that tells the ABS, traction control, and stability control systems how fast that wheel is turning; the control module sets this code when the signal from the left front sensor is missing, erratic, or out of range. Without a valid reading, the computer can't safely operate anti-lock braking and related systems, so it usually disables ABS and traction/stability control and lights the corresponding dashboard warnings (normal braking still works). It generally points to the sensor itself, its wiring, or the toothed reluctor ring it reads. Typical repair costs on Subaru range from $300 to $800, depending on the specific model and root cause.
Common Causes of C0035
- •Faulty left front wheel speed sensor
- •Damaged sensor wiring or connector (road debris, corrosion)
- •Metal debris or rust on the sensor tip or air gap
- •Damaged or cracked tone/reluctor ring
- •Loose or improperly seated sensor
- •Corroded or loose wheel bearing with integrated sensor
- •Open or short in the sensor circuit
- •Faulty ABS control module (less common)

- Premature Wheel Bearing Failure2013-2022
Crosstreks are prone to premature wheel bearing failure, particularly on the rear wheels, often occurring between 50,000-90,000 miles. The AWD system places additional stress on wheel bearings. Contamination from road salt and water intrusion accelerates bearing wear. Failed wheel bearings create a humming or growling noise that changes with vehicle speed and may be louder during turns. If ignored, a severely worn bearing can cause wheel wobble and ABS/traction control malfunctions.

What does C0035 mean on Subaru?▼
C0035 stands for "Left Front Wheel Speed Sensor Circuit." This chassis code indicates a fault in the left front wheel speed sensor circuit. Each wheel has a speed sensor that tells the ABS, traction control, and stability control systems how fast that wheel is turning; the control module sets this code when the signal from the left front sensor is missing, erratic, or out of range.
