The C1273 code for Scion 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 vehicle's anti-lock braking system (ABS) and traction control system. This sensor measures the speed of the right rear wheel and sends this information to the vehicle's electronic control unit (ECU) to assist in regulating the vehicle's braking and stability systems.
Common Causes of C1273 Scion
- Faulty rear speed sensor
- Damaged wiring or connectors leading to the sensor
- Corrosion or debris affecting the sensor's performance
- Issues with the ECU receiving the sensor's signal
- Mechanical damage to the wheel or sensor mounting area
Symptoms of C1273 Scion
- ABS warning light illuminated on the dashboard
- Traction control system malfunction
- Uneven braking performance
- Increased stopping distance
- Unstable handling on slippery surfaces
How to Fix C1273 Scion
- Begin by conducting a visual inspection of the rear speed sensor and its wiring to check for any visible damage, corrosion, or debris.
