Code C1193 Description

The diagnostic trouble code (DTC) C1193 indicates that there is a short circuit to ground in the right front speed wheel sensor input circuit. The wheel speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for monitoring the speed of the wheel and transmitting this information to the ABS control module to help prevent wheel lock-up during braking and improve traction control.
