I had an ABS code light up the other day. Hooked up my scan tool read a 11-1 Right Front Wheel Speed Sensor Open or Short. I viewed live data, and all sensors are reading speed except the front right. So, I replaced it with a $126 OEM speed sensor. Cleared the codes took for a drive with live data reading all wheel speed. A few days later it came back on. I read codes again and have the same thing and live data on scan tool is reading a 0 again. I figured maybe I have debris or something on back of the ring where wheel speed sensor reads. So, I cleaned it up and made sure the sensor was clean and put it all back together code clears by itself after driving a few miles. Then today it comes back on. What else can I check to fix this? Is there a way I can check the voltage or resistance? Something has to be wrong just can’t figure out what it is.

The car listed above is a 7th gen.

So, if the wheel bearing hub is going out the reluctor wheel will not line up on the sensor. Do you hear a humming noise coming from the right front wheel, if so, this will be the problem. Here is how to change it out.

If this is not the problem it would check the WSS circuits, here is a guide to help and the WSS wiring diagrams so you can see which wires to test and where.

No, I don't hear a humming noise coming from the right front wheel. I will check pink green and blk wire voltage from ABS module and get back to you. Thank you for the wiring diagrams.

So, I didn't find any voltage issues when testing with multimeter. I just replaced the wheel bearing anyway since this car has so many miles and that seemed like my only other option. It worked! ABS light is gone. I have 2 accords one with over 400k and then this one. Thanks for helping me keep these girls running with no dash lights. Hope to see 999,999 one day.
