C1260: Steering Angle Sensor Circuit / Signal (manufacturer-specific)
2 vehicles · 2 makes · $50-$1,500 repair
Most Reported On
C1260 is an OBD-II diagnostic trouble code meaning “Steering Angle Sensor Circuit / Signal (manufacturer-specific).” 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. This code is most commonly reported on 2021-2024 Kia K5, and 2015-2017 Hyundai Sonata, with repair costs ranging from $50 to $1,500.
