C1260 on Kia
Steering Angle Sensor Circuit / Signal (manufacturer-specific)
C1260 on Kia vehicles indicates steering angle sensor circuit / signal (manufacturer-specific). Au7o has documented this code across 1 Kia model — most commonly on K5. C1260 is a chassis code most commonly defined as a fault in the steering angle sensor (SAS) circuit or signal, used widely on Hyundai/Kia and GM vehicles (some platforms apply it to a wheel-speed comparison fault instead). The ABS/stability-control module relies on the SAS to know the steering wheel's angle and direction for electronic stability control calculations, and it sets this code when that signal is missing, corrupt, or illogical. The result is typically disabled stability/traction control with warning lights. Because the exact definition varies by make, confirm against the vehicle's service data. Typical repair costs on Kia range from $50 to $900, depending on the specific model and root cause.
Common Causes of C1260
- •Faulty steering angle sensor
- •Steering angle sensor needs recalibration/initialization
- •Worn steering coupler/clock spring (common on Hyundai/Kia)
- •Damaged wiring or connector to the SAS
- •CAN communication fault between SAS and ABS module
- •Faulty ABS/ESC control module
- •Recent steering or suspension work without recalibration
C1260 on Kia by Model
Kia K5(1 issue)
- Brake Booster / Vacuum Pump Noise and Reduced Brake Assist (1.6T)2021-2024
On 1.6T turbocharged K5 variants, some owners and NHTSA complainants have reported a hissing sound from the brake booster area upon brake pedal application, accompanied by a noticeably harder brake pedal and reduced power assistance. The GDi turbocharged engine uses an electric vacuum pump to supplement braking assist; failures or leaks in the vacuum pump, vacuum check valve, or booster hose connection reduce available vacuum and compromise brake pedal feel and stopping distance. This has been flagged as a safety concern in NHTSA filings.
