Does anyone know how to verify a bad wheel speed sensor as opposed to a bearing that was pressed in backwards or even doesn't have a magnet in it???
I replaced everything on the front passenger side and now have the VSA, ! and ABS lights up. I don't know if the sensor I replaced is faulty or if the problem is with the bearing I replaced. I'm 99% that I pressed it in stripe towards the sensor. The sensor is Honda and the bearing was NSK with a stripe.
I've paper clipped it and still get a code (ABS blinks 1 long and 2 quick) which apparently means 11-1?? which is the front right speed sensor.

Any help would be awesome.

Thanks

One long and 2 shorts is code 12. Code 12 is also RF, but is a sensor signal fault; noise or intermittent signal interuption.

Dirt or metal debris on encoder face will degrade and cause weak/no signal. Remove sensor and clean w/ rag stuffed into hole.

The sensor/encoder gap check spec is 20-50 mils gap.

I did not see any guidance on how to determine if signal output is good.

It might be possible to backprobe connector to wheel sensor and check for voltage pulse as wheel is rotated, no info on voltage level was presented in manual.

good luck

Thanks for the info!
The follow up question is how do you shim or even check the clearance the sensor to the bearing? The sensor body has a hole for which to insert the screw to hold it into the knuckle ( I don't think it's an oval hole to allow for adjustment)....

Manual doesn't say how. You'll have to look to see if there's access. I certainly wouldn't disassemble a wheel to look as odds are very high that gap is correct. Parts don't touch/wear.

Easy to clean bearing and sensor and see if code clears.

good luck
