I am so stoked right now after fixing the damn ABS light. The 2000 accord coupe has about 201k miles (not my DD anymore). Anyways I ordered two standard motors rear ABS sensors (ALS802 and ALS800) from rockauto, who delivered them so freaking fast haha. The night I installed them the damn ABS light still came on. The next day I reset the light and it came back on. After doing the paper clip scan I knew the two rears were still the culprit.
I did the resistance test and then the voltage test both on a cheapo multimeter.
Resistance was fine (around 17xx and stable) but there was NO voltage generated at all when I hand spun the wheel.
Turns out there was so much rust build up that I had to clean the surface some more with a dremel!
Then I had to reposition the sensors in such a way so that when I manually spun the wheel a voltage was read on the multimeter.
Interesting that the positioning of the sensor can make a difference bc there really isn't a lot you can move around. But then again that hole isn't exactly in good shape at all. I had to chip away what was left of the old sensor and the rust. not fun.
The light went off by itself right away so I knew it was fixed. So many of the you tube videos showing replacement don't mention this but I highly recommend on an older car to check the resistance and voltage of the new sensors before putting everything back b/c the sensor tip needed to be VERY close to the reluctor ring.
Hope this helps someone!
