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.
Common Causes of C1416 Scion
- Faulty rear left speed sensor
- Damaged or corroded wiring/connectors leading to the sensor
- ABS module malfunction
- Wheel bearing issues affecting sensor operation
- Contaminated sensor surface affecting signal output
Symptoms of C1416 Scion
- Illuminated ABS warning light on the dashboard
- Traction control system warning light may also be illuminated
- Erratic or inconsistent ABS operation during braking
- Increased stopping distances or reduced braking effectiveness
- Traction control system may not engage when needed, leading to wheel spin
How to Fix C1416 Scion
- Begin by diagnosing the specific cause of the C1416 code using a professional diagnostic scan tool.
- Inspect the rear left speed sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Test the sensor's output signal using a multimeter to ensure it is within the manufacturer's specified range.
- Check the ABS module for any faults or malfunctions. Repair or replace the module as needed.
- Clear the DTC and perform a road test to verify that the issue has been resolved and that the ABS and traction control systems are functioning correctly.
Cost to Fix C1416 Scion
The typical repair costs for addressing a C1416 code on a Scion vehicle can vary depending on the specific cause of the issue and the labor rates in your area. On average, replacing a rear speed sensor can cost between $100 and $200, including parts and labor. However, if additional components such as the ABS module need to be replaced, the total repair cost could increase significantly. It's recommended to consult with a qualified mechanic or auto repair shop to obtain an accurate estimate based on your vehicle's make and model.
