This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal that's too high from the sensor on the right front wheel. This sensor helps the car know how fast the wheel is turning.
The right front wheel speed sensor is sending a voltage signal that is higher than expected to the vehicle's computer.
The C065B code indicates that the right front wheel speed sensor B is sending a signal voltage that is above the normal operating range. This could be due to a short circuit, faulty sensor, or wiring issues.
• ABS warning light on
• Traction control system malfunction
• Inconsistent speedometer readings
• Faulty right front wheel speed sensor
• Short circuit in the sensor wiring
• Damaged or corroded connector
ABS: Anti-lock Braking System
OBD-II: On-Board Diagnostics II
• Inspect the right front wheel speed sensor and wiring for damage.
• Check the sensor connector for corrosion or loose connections.
• Use a multimeter to measure the voltage output from the sensor.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring.
• Clean or replace corroded connectors.

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect wheel speed sensors and wiring.
• Keep connectors clean and free from corrosion.
• Avoid driving through deep water to prevent sensor damage.
Sensor Issue
• Avoid driving at high speeds until the issue is resolved.
• Get the vehicle inspected by a professional mechanic.
Check with your vehicle's manufacturer for warranty coverage on sensor-related issues.
This code has been associated with issues in vehicles with advanced ABS and traction control systems, particularly in models with high mileage.
Moderate – While the vehicle may still be drivable, the ABS and traction control systems may not function properly.
Driving with a malfunctioning ABS system can increase stopping distances and reduce vehicle control in emergency situations.
• Vehicle ignition on
• Vehicle in motion
The right front wheel speed sensor is located near the right front wheel hub assembly.
Q: Can I drive with a C065B code?
A: It's possible to drive, but it's not recommended as the ABS and traction control systems may not work properly.
Q: How do I reset the ABS light after fixing the issue?
A: After repairs, use an OBD-II scanner to clear the code and reset the ABS light.
