• C1225
• C1226
This code means that there is a problem with one of the car's wheels, and it might not be spinning correctly. It's like when you try to ride a bike, but one of the wheels is stuck or not moving right.
The C1224 code indicates an issue with the wheel speed sensor or its circuit, which affects the vehicle's ability to monitor and control wheel speed accurately.
C1224 is a chassis code related to the wheel speed sensor circuit. This sensor is crucial for the anti-lock braking system (ABS) to function properly. It monitors the rotational speed of each wheel and sends this data to the ABS control module. If the module detects an anomaly in the sensor's readings, it triggers the C1224 code.
• Inspect the wheel speed sensor for physical damage.
• Check the wiring and connectors for corrosion or disconnection.
• Use a scan tool to read sensor data and confirm the fault.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Reset the ABS system and clear the code.
• OBD-II scanner
• Multimeter
• Socket set

• Regularly inspect wheel sensors for damage.
• Keep sensor areas clean and free from debris.
• Ensure proper maintenance of the ABS system.
Sensor Issue
• Avoid sudden braking until the issue is resolved.
• Drive carefully, especially in wet or slippery conditions.
Check with your vehicle manufacturer for warranty coverage on ABS components.
This code has been commonly reported in vehicles with high mileage or those that frequently drive in harsh conditions.
Moderate – While the vehicle is still drivable, it is important to address this issue to maintain safe braking performance.
Driving with a malfunctioning ABS can increase stopping distances and reduce control during emergency braking.
• Drive the vehicle at a moderate speed.
• Perform a gentle braking test to observe ABS functionality.
The wheel speed sensor is located near the brake rotor on each wheel.
Q: Can I drive with the C1224 code?
A: Yes, but it is not recommended to drive for long periods without addressing the issue, as it affects braking performance.
Q: How do I reset the ABS light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes to reset the system.
