Bad wheel speed sensor.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your Corolla. You can use an OBD-II scanner with ABS capabilities to determine which wheel speed sensor is faulty. This tool can read the trouble codes stored in the vehicle's computer, indicating which sensor is malfunctioning. The code will usually specify which wheel (front left, front right, rear left, or rear right) is affected. It may be best to consult a trusted repair shop for a diagnosis, as these codes do not always mean an ABS sensor has failed. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
