Code C1273 2018 Toyota RAV4 Description
The C1273 diagnostic trouble code (DTC) in a 2018 Toyota RAV4 indicates a low output signal from the rear speed sensor on the right side of the vehicle. The speed sensor is a crucial component of the anti-lock braking system (ABS) and traction control system, as it monitors the speed of the wheels and sends this information to the vehicle's electronic control unit (ECU). When the ECU detects a low output signal from the rear speed sensor on the right side, it can lead to issues with the ABS and traction control systems, affecting the vehicle's overall performance and safety.
