Code C1416 Scion Description

The C1416 diagnostic trouble code (DTC) for Scion vehicles indicates a Rear Speed Sensor Left Output Malfunction. This code is specifically related to the rear left speed sensor, which is responsible for monitoring the speed of the wheel and sending this information to the vehicle's anti-lock braking system (ABS) and traction control system. When the sensor detects an issue with its output signal, it triggers the C1416 code.
