Well, I gave up trying to get the plug apart, couldn't budge it. So, instead, I cut the wires at the sensor. That allowed me to get my MC wrench on the sensor and get it off easy enough.


Then I used needle-nose pliers to hold each wire and trim the insulation, and connected to the new sensor wires with crimp connectors. I looped the excess up to a wire bundle on the firewall. I will not have this problem when I need to replace the sensors next time, now I have plenty of slack in the wires to cut and connect.

Passed emmissions inspection.

Update: I see Autozone is selling that 22mm sensor socket for around $9 now. Not the part online, but in the generic packaging with the jaw pullers.

Default P0153

so i have a 2004 verona also about 110 k
and finally getting the P0171 P0174 and P0153 O2 sensor codes.
my mechanic friend is simply refusing to let me believe it's only a matter of the O2 sensor. He keep saying there are many reasons for the thing to read oil running lean. P0153 is Os sensor slow circuit or something like that, should i try to change the O2 sensor first or just take it to the shop

*there were problems with the cars electrical system, i had to replace the fuse harness

Your friend makes a valid point.

See this article...
Oxygen Sensor Codes - A Complete Guide On Diagnosing Automotive Oxygen Sensors

I'd suggest first conducting the preliminary maintenance as described in the article and then clearing the ECU codes (battery disconnect or with scan machine), followed by another scan to observe what codes return and pop up first. This will allow you to better diagnose the problem.

Default Oxygen sensor sockets

In this thread there are pictures of two oxygen sensor sockets, one being a Tekton posted by Max with a 3/8" offset hole and the other being a star hole. I have now both but the problem for the driver side (U.S.) oxygen sensor replacement is that there is not enough clearance to fit a breaker bar (or offset wrench) to the hole. On the one side, the transmission oil dipstick tube interferes. So what I have on order is a Lisle 12390 oxygen sensor socket, which has the same design but with what should be to me a very important 1/2" hole at the end of the "foot."

https://www.amazon.com/Lisle-12390-O...+sensor+socket

The other socket worked well for the passenger side, but no matter how hard I try I can't get a bar or wrench or extension under to that little hole. They're just too thick.

You can also opt to disconnect the harness and use a box end wrench.

I do and did see the wrench pictured, but as to the driver side sensor given the handle length I have considerable doubt that a box wrench can actually fit in the relevant area. The firewall would readily prevent it in my estimation. If the Lisle does not work, my plan is to cut the existing sensor in half and get a regular 22 mm socket on it, with a handle shorter than pictured. Right now I'm shopping for a short "handle" for the Lisle socket 1/2" foot end drive hole.

Default Success using the Lisle socket w/ 1/2" hole and three 1/2" drive extensions

Wrapping up - See pics, depicting the Lisle 22 mm socket identified in my above post with the key 1/2" drive hole at end of "foot"; 3" extension (1/2" drive); 9" long L shaped drive extension (1/2" drive); and 5" extension (1/2" drive).
For a 2002 XL-7, the pieces fit together in precisely that order to enable snake around in the engine bay avoiding the tubes etc., and enough extension for twisty torque on the 22 mm nut. The assembled version shows roughly how the apparatus looked when peering at it over the fender.
Thanks to all - including especially Max and Scorch.
