This information is crucial for the ABS to regulate brake pressure and prevent wheel lock-up during sudden braking or slippery road conditions.
Common Causes of C1416
- Faulty rear speed sensor
- Damaged wiring or connectors leading to the sensor
- Corrosion or debris affecting the sensor's mounting surface
- Malfunctioning ABS control module
- Electrical issues within the ABS system
Symptoms of C1416
- ABS warning light illuminated on the dashboard
- Irregular ABS system activation during braking
- Increased stopping distances during braking
- Loss of traction control functionality
- Grinding or scraping noise coming from the rear of the vehicle during braking
