what can I do about code C0045-0F

Question

I have a 2014 Chevy Impala and today it gave me code C0045-0F saying that the left wheel speed sensor circuit signal erratic. I tested the sensor itself with an Omn meter and came back with what I assume is good because its reading matched what the other sensors readings were that are working. This is all I have done so far. I am not sure what to do next any advice would be much appreciated. Thanks in advance.

Answer 1

You can't test the sensor with an Ohm meter, you have to use an oscilloscope to check signal. Have you done any mechanical repairs on that side (e.g. replaced brakes, hubs, etc.)? You could try cleaning the sensor and make sure there is no debris around the sensor.
