Pedal assist stopped working on BBS02

Ok, thank you. I am in touch with the Amazon seller who sold it to me as well. I was hoping it was something I could figure out on my own and I could learn something, but at this point, perhaps not!

Bafang BBS02 throttle works but pedal assist does not - Electricbike.com Ebike Forum
I'm at my wit's end with this problem that I'm having and hoping that somebody here can help me troubleshoot. I bought a second hand Bafang BBS02, 750w kit. I put it on my bike and everything works except for the pedal assist. The throttle works fine, the walk assist works fine, but when I...

DIY Fix for BBS02/BBSHD Pedal/Throttle Issue
EDIT: 4/20/21; After 3 years my fix described in this post quit working. I didn't try to figure out why, simply removed it to make sure everything worked as originally shipped from Bafang. Also, I had another fix I wanted to try which is simple and requires no electronic parts. I completed...

I found this on the web for the location of the PAS which connects inside the controller cover, aparently there is a connector that could be disconected, but in the vides it's alittle hard to see which whir he is disconnecting .https://www.ebay.com/itm/PEDAL-ASSIST-SENSOR-PAS-FOR-BEWO-MID-DRIVE-ELECTRIC-BIKE-KIT-EBIKE-PAS-SENSOR-/124236443744.
I'll see if I can find that video again so you can check the connector.

At about 2;32 on this video you can see the connector for the PAS sensor coming out from the housing that holds the crank. Edit: It shows up earlier but he never discusses it.
I think you will need a motor replacement under warranty. Perhaps your seller will not want the old motor back, but it's not worth going this deep if it invalidates your warranty. It could just be a loose connector, but it could be a bad PAS sensor, and you're not going to find it easy to get a new one.

Some don't know the difference between a speed sensor magnet and/or a PAS sensor

I've seen strange behavior when the speed sensor isn't flashing as the magnet passes. And BEWO has NO relavence here.
Thanks. Yeah, I am definitely concerned about invalidating the warranty. Looking forward to seeing what the seller says!

Be patient... We'll get this figured out.
Definitely wait to hear from the vendor
Do you mind if I ask their name?

Warranty? I'm sorry for the sarcasm, but too often resellers and even Bafang can be a PIA for warranty coverage.
Which vendor on Amazon did you use?

Really a lot more work than on a hub motor !
On a hub, you have very easy acess to both the PAS wheel and the sensor.
Good luck !
