Need some help - wheel speed sensor?

[marine2651]

Hey all,

I just replaced the original S22 with a brand new one over the weekend. Had a shop mount and balance and I did all of the rest of the work myself. Took the bike out for a shakedown run and I'm getting the ABS light, the Yellow triangle warning light and the TC light and the bike goes into what I call limp mode (degraded power and all of the assistance systems seem to be at max). I'm thinking it is the wheel speed sensor causing this, but it has been cleaned, no apparent damage of any kind to it so I'm at a loss. Any thoughts or guidance on running this down would be greatly appreciated.

Disconnect the battery for a couple minutes and see if it will reset.
If the FI light is not on, then there are no current codes to be read.

Check that your sensors are screwed down tight, some shops remove the front and rear wheel sensors to lift the bike off the ground to get the wheels off.

Then get your codes cleared and start fresh. There was no reason to remove the abs pulse sensor wheels on either wheel, unless for some dumb reason they put the front wheel on backwards. I don't think that's the case. Check the arrow on the wheel, so you know it's facing forward. There's also indicators on the tire that should match that same direction.

Keep it simple start with the basics. Make sure your sensors are attached and tightened down. Clear your codes.

Also, double check that you have 73 foot pounds on your front axle nut and your back axle nut and then on the front pinch bolts. They are tightened to 23 Newton meters or 17 foot pounds.

Thanks all. It was only the rear wheel that was removed with pulse sensor wheel intact, checked the torque and all is good. Sensor is in and tightened to spec no obvious defects of any kind that I can see with the sensor itself nor the pulse sensor wheel.

There are no codes presenting, and I've disconnected the battery for several minutes (while it was up on the rear stand if that makes any difference).

Took it down off of the stand and ran around the neighborhood a bit and noted ABS light and yellow warning triangle came on under moderate acceleration but went out again when I slowed to @ 20mph. The TC light flashed on when I took a turn returning to the house but went back out as soon as I straightened back out. Slow speed turn from a stop sign, so no chance there would have been wheel spin.

Thanks again for all of the suggestions and please keep them coming if anything else comes to mind.

something similar happened to me in the past, Rear ABS speed sensor cable was damaged.
