C0245 on Chevrolet
Wheel Speed Sensor Frequency Malfunction
C0245 on Chevrolet vehicles indicates wheel speed sensor frequency malfunction. Au7o has documented this code across 2 Chevrolet models — most commonly on Colorado, Equinox. C0245 is a chassis/brake code (predominantly GM) meaning the electronic brake control module received an erratic or irrational frequency signal from a wheel speed sensor compared with the other wheels. It often sets when the module cannot pinpoint which specific sensor is at fault, and on some GM trucks/SUVs it is tied to a known EBCM internal solder-joint failure. Because wheel speed signals feed ABS, traction, and stability control, these systems may be disabled while the code is active, though base braking still works. Typical repair costs on Chevrolet range from $180 to $1,200, depending on the specific model and root cause.
Common Causes of C0245
- •Faulty wheel speed sensor
- •Damaged sensor wiring or connector
- •Corroded or damaged tone ring / reluctor
- •Metal debris or contamination on the sensor
- •Internal EBCM/ABS module fault (cracked solder joints on GM)
- •Wheel bearing with integrated sensor failing
- •Excessive air gap or sensor mounting issue
C0245 on Chevrolet by Model
Chevrolet Colorado(1 issue)
- ABS Module / Wheel Speed Sensor Faults Causing ABS Warning and Intermittent Brake Activation2004-2012
Colorado owners frequently report ABS warning lights, stored wheel speed sensor faults, and low-speed unwanted ABS activation, especially in rust-belt trucks. Corrosion at the front hub sensor mounting area or failing hub-integrated wheel speed sensors can create an erratic signal that the ABS module interprets as wheel slip. This issue is widely documented across GM midsize trucks and often shows up as pulsation or extended stopping distance at parking-lot speeds.
Chevrolet Equinox(1 issue)
- Brake Pressure Modulator Valve Corrosion Causing ABS Malfunction and Extended Stops2007-2009
A known safety issue on later first-generation Equinox models involves corrosion in the brake pressure modulator valve (BPMV), which can cause the ABS to activate improperly at low speeds. Owners report a sudden buzzing pedal, unexpected increase in stopping distance, and the vehicle seeming to roll through a stop on dry pavement. This problem was serious enough to trigger a GM safety recall in salt-belt states.

What does C0245 mean on Chevrolet?▼
C0245 stands for "Wheel Speed Sensor Frequency Malfunction."
