C0035: Left Front Wheel Speed Sensor Circuit
18 vehicles · 10 makes · $100-$2,000 repair
Most Reported On
C0035 is an OBD-II diagnostic trouble code meaning “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. 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. This code is most commonly reported on 2000-2007 Ford Focus, 2011-2023 Chrysler 300, and 2013-2022 Subaru Crosstrek, plus 15 other vehicles, with repair costs ranging from $100 to $2,000.
