• C1225
• C1226
The car's computer is getting confusing information from the wheel speed sensor, which helps it know how fast the wheels are spinning.
The wheel speed sensor sends signals to the car's computer to help it understand how fast each wheel is turning. If the signal doesn't make sense, the computer can't use it properly.
The C1228 code indicates that the signal from one or more wheel speed sensors is not consistent with expected values. This could be due to electrical issues, sensor malfunction, or incorrect sensor installation.
• Check for any visible damage to the wheel speed sensor and wiring.
• Use an OBD-II scanner to read the sensor data.
• Test the sensor's electrical connections and continuity.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Ensure proper installation and alignment of the sensor.

Sensor Issue
• Drive cautiously until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer; wheel speed sensors may be covered under certain warranties.
This code has been associated with sensor and wiring issues in various vehicle models over the years.
Moderate – While the vehicle may still be drivable, the ABS and traction control systems may not function properly.
Ignoring this issue could lead to reduced braking performance and increased stopping distances.
• Vehicle at rest
• Vehicle in motion
The wheel speed sensor is typically located near the wheel hub assembly on each wheel.
Q: Can I drive with a C1228 code?
A: You can drive, but it's not recommended as your ABS and traction control systems may not work properly.
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.
