Code C1224 Pontiac Description

The C1224 Pontiac code indicates that the right rear wheel speed sensor input signal is registering as zero. In modern vehicles, wheel speed sensors are crucial components of the anti-lock braking system (ABS) and traction control system. These sensors monitor the speed of each wheel and send this information to the vehicle's electronic control module (ECM). When the ECM detects that the right rear wheel speed sensor is not providing any signal, it can lead to issues with the ABS and traction control systems.
