C1235 on Ford
Manufacturer-Specific Chassis/ABS Wheel-Speed Sensor Circuit Code
C1235 on Ford vehicles indicates manufacturer-specific chassis/abs wheel-speed sensor circuit code. Au7o has documented this code across 1 Ford model — most commonly on Flex. C1235 is a manufacturer-specific chassis/ABS code most commonly associated with a wheel-speed sensor circuit (for example, a rear wheel speed circuit reported as open or shorted on some makes). It indicates the ABS/stability control module detected an electrical fault or implausible signal in a wheel-speed input it monitors. When set, ABS and traction/stability control are usually disabled and the related warning lights illuminate, though normal braking remains. Confirm which wheel and circuit are involved for your specific make and model using a capable scan tool or factory service data. Typical repair costs on Ford range from $230 to $600, depending on the specific model and root cause.
Common Causes of C1235
- •Faulty wheel speed sensor
- •Damaged tone/reluctor ring (chipped or rusty teeth)
- •Open or shorted sensor wiring
- •Connector corrosion or damage
- •Excessive sensor air gap or debris buildup
- •ABS/stability control module fault

Ford Flex(1 issue)
- Front and Rear Wheel Hub Bearing Failure With Corrosion-Welded Hubs2009-2019
Sealed hub bearing assemblies on the Flex wear out and produce a speed-dependent noise that owners consistently describe as starting like a hum and progressing to a sound like aggressive snow tires, usually first noticed above 40 mph and changing pitch when the vehicle is loaded up in a turn. It affects both front and rear (including rear hubs on AWD cars). What makes this repair worse than on other vehicles is corrosion: the bearing race seizes to the knuckle/spindle, so the whole spindle often has to come off the car and the bearing pressed out, turning a routine job into a multi-hour fight.
