C0035 on Chevrolet
Left Front Wheel Speed Sensor Circuit
C0035 on Chevrolet vehicles indicates left front wheel speed sensor circuit. Au7o has documented this code across 4 Chevrolet models — most commonly on Silverado 1500, Suburban, Tahoe. 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 Chevrolet range from $100 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)
C0035 on Chevrolet by Model
Chevrolet Silverado 1500(1 issue)
- Front Wheel Hub Bearing Failure Triggering ABS Warning and Growling Noise2000-2013
Silverado 1500 trucks commonly develop front hub bearing wear, especially on higher-mileage 4x4s and trucks used on rough roads or with oversized tires. Owners report a humming or growling noise that changes with speed and steering input, and because the wheel speed sensor is integrated into the hub assembly, ABS and traction control warnings may appear as the bearing deteriorates. Excessive play can eventually affect braking feel and tire wear.
Chevrolet Suburban(1 issue)
- Front Wheel Hub Bearing Failure (ABS Light)1994-2007
The sealed front wheel bearing/hub assemblies on 4WD Suburbans wear out and are a top high-mileage complaint. Because the ABS wheel-speed sensor is integrated into the hub, a failing bearing (or a failed sensor) commonly triggers the ABS and traction/StabiliTrak warning lights along with a cyclic humming/growling that changes with speed and cornering load. The hub is a non-serviceable sealed unit.
Chevrolet Tahoe(1 issue)
- EBCM / ABS Module Failure & Corroded Ground (ABS, Traction, StabiliTrak Lights)2000-2006
GMT800 Tahoes commonly light the ABS, Traction Control and (on later trucks) StabiliTrak warnings simultaneously due to the Electronic Brake Control Module (EBCM) or, very often, its corroded frame-mounted ground. The dedicated EBCM ground on the driver-side frame rail is exposed to road salt and corrodes, causing intermittent module communication loss and codes like C0265. Internal EBCM solder-joint failures also occur. Normal service braking still works, but ABS/traction functions drop out.
Chevrolet Traverse(1 issue)
- Service StabiliTrak / Traction Control Warnings with Reduced Power2018-2021
Traverse owners frequently see 'Service StabiliTrak' and 'Traction Control Off' messages appear together while driving, sometimes accompanied by an engine power reduction. The warning is a downstream symptom rather than a single fault: common triggers are a failing wheel speed sensor, an ABS/EBCM module or wiring-harness fault, or an underlying engine misfire that disables the stability system. The intermittent nature makes it frustrating to diagnose without scanning stored codes.
