C0035 on Kia
Left Front Wheel Speed Sensor Circuit
C0035 on Kia vehicles indicates left front wheel speed sensor circuit. Au7o has documented this code across 1 Kia model — most commonly on Rio. 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.
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)

Kia Rio(1 issue)
- HECU Electrical Short / Engine Fire Risk2012-2017
The 2012-2017 Rio is included in the broader Kia HECU recall for an electrical short in the Hydraulic Electronic Control Unit (ABS module) that can cause an engine compartment fire. The HECU can short-circuit internally even while the vehicle is parked. Kia replaces the fuse and inspects the HECU assembly.
