C1235 on Toyota
Manufacturer-Specific Chassis/ABS Wheel-Speed Sensor Circuit Code
C1235 on Toyota vehicles indicates manufacturer-specific chassis/abs wheel-speed sensor circuit code. Au7o has documented this code across 1 Toyota model — most commonly on Yaris. 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 Toyota range from $20 to $700, 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
C1235 on Toyota by Model
Toyota Yaris(1 issue)
- Rear Wheel Speed Sensor Corrosion at the Hub Connector (ABS and Brake Warning Lights)2007-2018
A very common Yaris electrical fault: the rear wheel speed sensor is integrated into the rear hub/bearing assembly and is not sold separately. The weather seal where the harness plugs into the hub has a gap, so road spray and winter salt wick into the connector, corrode the pins and degrade the signal. The ABS light and the red brake/'!' light come on together, often intermittently at first and worse in wet or winter weather. Dealers routinely quote a complete rear hub assembly (owners report $650-750 CAD per side) when the actual fault is frequently just a dirty, corroded connector.
