This code means there's a problem with the car's wheel speed sensor, which helps the car know how fast each wheel is spinning. It's like when your bike's speedometer isn't working right.
The C0042 code indicates an issue with the right front wheel speed sensor circuit.
The C0042 code is triggered when the ABS (Anti-lock Braking System) module detects a malfunction in the right front wheel speed sensor circuit. This sensor is crucial for monitoring the speed of the wheel to ensure proper braking performance.
• Inspect the right front wheel speed sensor and its wiring for damage.
• Check the connector for corrosion or loose connections.
• Use a multimeter to test the sensor's resistance and signal output.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
