C1261 on Kia
Manufacturer-Specific Chassis Code (Steering Angle Calibration or ABS Inlet Valve Solenoid)
C1261 on Kia vehicles indicates manufacturer-specific chassis code (steering angle calibration or abs inlet valve solenoid). Au7o has documented this code across 1 Kia model — most commonly on K5. C1261 is a manufacturer-specific chassis code with meaning that varies by maker; reported definitions include a wheel/steering angle sensor not-calibrated condition (Kia) and a left front inlet valve solenoid malfunction in the ABS (Chevrolet/GM). In general it indicates that a chassis/ABS control module detected a calibration problem or an electrical fault in a circuit it monitors. Setting this code typically disables or limits ABS and traction/stability control and lights the related warnings. Confirm the exact definition for your specific make and model using a capable scan tool or factory service data before repair. Typical repair costs on Kia range from $50 to $900, depending on the specific model and root cause.
Common Causes of C1261
- •Steering/wheel angle sensor not calibrated
- •Faulty steering angle sensor
- •ABS inlet valve solenoid circuit fault (GM applications)
- •Wiring or connector damage / corrosion
- •ABS/stability control module (HCU) fault
- •Open or short circuit in the affected circuit

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.
