Code C1273 2016 Toyota RAV4 Description

The C1273 diagnostic trouble code (DTC) for a 2016 Toyota RAV4 indicates a low output signal of the rear speed sensor on the right side of the vehicle. The rear speed sensor is a crucial component of the anti-lock braking system (ABS) and traction control system. It is responsible for measuring the speed of the right rear wheel and sending this information to the vehicle's electronic control unit (ECU). This data is used by the ABS and traction control systems to regulate wheel speed during braking and acceleration, helping to prevent wheel lock-up and loss of traction.
