Code C1401 Scion Description
The C1401 Scion code indicates a malfunction in the front speed sensor on the right side of the vehicle. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for monitoring the speed of the wheel and sending this information to the ABS control module. This data is used to determine when a wheel is locking up during braking or losing traction, allowing the ABS system to intervene and prevent skidding.
Common Causes of C1401 Scion
- Damaged or worn front speed sensor
- Corroded or damaged wiring connecting the sensor
- Poor sensor alignment or mounting
- Electrical issues such as a blown fuse or relay
- Faulty ABS control module
Symptoms of C1401 Scion
- ABS warning light illuminated on the dashboard
- Traction control system warning light activated
- Increased stopping distances during braking
- Loss of traction or stability on slippery roads
- ABS system engaging unexpectedly or not engaging when needed
How to Fix C1401 Scion
- Diagnose the issue by connecting a scan tool to retrieve the specific fault code and confirm the malfunctioning front speed sensor.
- Inspect the sensor, wiring, and connections for any damage or corrosion. Replace any faulty components.
- Adjust or replace the sensor if it is misaligned or improperly mounted.
- Clear the fault code from the ABS control module and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be needed to identify any underlying electrical or control module issues.
Cost to Fix C1401 Scion
The typical repair costs for a front speed sensor right malfunction can range from $150 to $300 for parts and labor. However, it's important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.

Tech Notes for C1401 Scion
If there is iron powder sticking to the rotor, this will result in a malfunction, so confirm that the rotor is not contaminated with foreign material before replacing the sensor.
Check the speed sensor signal after cleaning or replacement.
On most vehicles, the Front Speed Sensor Rotor is incorporated into the Front Axle Hub Sub-Assembly. If the Speed Sensor Rotor needs to be replaced, replace it together with the Front Axle Hub Sub-Assembly.
