What are the symptoms of C0035?

ABS warning light on. Traction control disabled. Stability control offline (VSC / ESC / EBCM warning). ABS activates during normal stops

Raise vehicle, spin wheel by hand, watch live data — sensor dropout confirms bad sensor or wiring. Inspect wire harness from sensor to ABS module; look for chafe points on steering knuckle. Check sensor gap — spec typically 0.020–0.050". Replace hub bearing if gap is excessive or tone ring damaged. Replace wheel speed sensor ($15–45 DIY) or full hub/bearing assembly if tone ring is integral

C0035

Chafed or torn wiring harness to left front sensor
Failed wheel speed sensor (open or shorted internally)
Tone ring / reluctor ring damaged or cracked (integrated into wheel hub bearing)

Direct Repair Steps

Raise vehicle, spin wheel by hand, watch live data — sensor dropout confirms bad sensor or wiring
Inspect wire harness from sensor to ABS module; look for chafe points on steering knuckle
Check sensor gap — spec typically 0.020–0.050". Replace hub bearing if gap is excessive or tone ring damaged
Replace wheel speed sensor ($15–45 DIY) or full hub/bearing assembly if tone ring is integral
