Code C1405 Lexus Description
The C1405 diagnostic trouble code for Lexus vehicles indicates an open or short in the front speed sensor right circuit. The front speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. The speed sensor is responsible for monitoring the speed of the wheels and sending this information to the vehicle's electronic control unit (ECU). This information is essential for the proper functioning of the ABS and traction control systems, as they rely on accurate wheel speed data to operate effectively.
Common Causes of C1405 Lexus
- Damaged wiring or connectors in the front speed sensor circuit
- Faulty front speed sensor
- Corrosion or contamination in the sensor area
- Issues with the ECU or ABS module
Symptoms of C1405 Lexus
- ABS warning light illuminated on the dashboard
- Traction control system malfunction warning
- Inaccurate speedometer readings
