Great detailed info John. I have the same tool pictured but like Max have also cut the wires on stubborn sensors. Way more confidence when you have a fat 1/2" drive socket & ratchet on their.

At Rockauto it looks like there are 3 NTK sensor part numbers. Maybe because of cable lengths? Looks like about $140 plus shipping. This search is for the year of my van, 07. Looking at 05 I see 24302 for $116 each on the bottom one and you'd need two. Ouch.

24259 - Downstream Front; OE MFR: NTK $55
24255 - Downstream Rear; OE MFR: NTK $55
24346 - Fits Upstream Rear; OE MFR: NTK Or Upstream Front; OE MFR: NTK $64 (for 07, 05 looks to be 24302 for $116ea)
