Subaru Problems? Ask a Mechanic for Answers ASAP
Hello and thank you for your question!My name is ***** ***** I will be assisting you with your question today.
Sorry to say, the only method to determine which sensor is sending the code is a scan tool that can either watch the wheel speeds or read the codes from the ABS control module. If you have a bad wheel bearing or can hear howling or growling it could be the cause of the code. This will change the air gap between the sensor and the tone ring and set the code. This is really about the only insight you can have without a scan tool.
