I was doing preventative maintenance on the mdx. I replaced bank 1 and bank 2 precat sensors. After I finished I ran the car and get a p0135 error. Heck i didn't have an error before. Now I put 2 new sensors and I have an error. Any ideas what went wrong here. Some people talk about a fuse for the o2 sensors. Any idea where this is located?

The sensors I put in are Denso 2345053. The ones I took out are NTK LHA LZA08-H8 and NTK LHA LZA08-H9

A close inspection revealed the wires not connected. Bad crimping. Hard to believe. I don't even know how to remove this connector and redo it

you will have to remove the terminals from the connector housing and try to crimp the wires.

Vendor warranty?

Best bet to get them properly repaired is a local auto electric shop. They have the tools and experience. Shouldn't cost too much.

I bought from eBay as OEM DENSO. The seller offered to replace them stating that the warehouse may have accidentally sent defective parts. I said I lost confidence in his product and I want a refund.The seller refunded me and told me to not send back the parts. I now doubt they are originalnal DENSO sensors because of the poor crimping. I probably can re crimp them and place a little solder to keep them from coming lose again, but I was doing this as preventative maintenance, and I don't want o replace a known good part with a sketchy one.
