OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics in vehicles.
ABS: Anti-lock Braking System, a safety system that prevents wheels from locking up during braking.
• C0035
• C0040
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.
C0072 is a diagnostic trouble code indicating an issue with the wheel speed sensor.
The C0072 code is set when the vehicle's control module detects a malfunction in the wheel speed sensor circuit. This sensor is crucial for systems like ABS and traction control, as it provides information about the speed of each wheel.
• Inspect the wheel speed sensor and associated wiring for damage.
• Use a multimeter to test the sensor's electrical resistance.
• Check the ABS module for error codes and proper operation.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ABS module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect wheel speed sensors and wiring.
• Keep the wheel hubs clean and free from debris.
• Address ABS warning lights promptly.
Sensor Issue
• Avoid driving at high speeds until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle's manufacturer for specific warranty coverage on ABS components.
C0072 has been a common issue in vehicles equipped with ABS systems, particularly as they age and components wear out.
Moderate – While the vehicle may still be drivable, safety systems like ABS may not function properly.
Driving with a malfunctioning ABS system can increase stopping distances and reduce vehicle control during emergency braking.
• Vehicle stationary
• Ignition on, engine off
The wheel speed sensor is typically located near the wheel hub or brake rotor.
Q: Can I drive with a C0072 code?
A: While the car may still be drivable, it's not recommended as the ABS system may not work properly.
Q: How do I reset the C0072 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
