C1260 on Hyundai
Steering Angle Sensor Circuit / Signal (manufacturer-specific)
C1260 on Hyundai vehicles indicates steering angle sensor circuit / signal (manufacturer-specific). Au7o has documented this code across 1 Hyundai model — most commonly on Sonata. 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.
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

- MDPS / Electronic Power Steering (EPS) sudden assist loss and steering lockup2015-2017
The Motor-Driven Power Steering (MDPS) unit can fail, illuminating the EPS warning light and causing sudden loss of power assist or a steering wheel that becomes very tight/hard to turn - sometimes during low-speed maneuvers (parking, tight turns) and sometimes at highway speed (~35 mph). Owners report having to stop, shift to park, and restart the engine to clear the light, and that the wheel can briefly 'lock' or require very high effort. Root causes traced to the MDPS module/motor, wiring-harness connections, or the steering-angle sensor. Hyundai issued a warranty extension covering the MDPS/EPS unit for EPS-warning-light illumination on 2016-2017 model-year vehicles from 5yr/60,000 mi to 15yr/150,000 mi.
