95 D1 O2 Sensor Replacement ?s

[jkipk]

OK I've been searching the archives like a good boy and I just want to confirm a couple of things before I proceed.

BACKGROUND: Check Engine Light came on for the first time yesterday (@132k mi). Code 45 - Right Lambda Sensor.

I've read about how to clear the code, but I want to make sure I'm unplugging the right plug - I switch ignition on, unplug the serial plug to the code display under the pass. seat, wait 5+sec, plug it back in, and turn the ignition off, wait, and then on again. Is that right? Doing so gives me the same 45 code immediately after turning the ignition off/on (screen is black after I plug the plug back in)

Any further advice on how to get the O2 sensor plug apart? I read about it being hard to do, and initial trial confirms this - don't want to have to make up any new swear words if I don't have to.

I found info on the codes in the RAVE CD, but is there a section on the under-seat display and it's workings? I haven't found anything but stuff on TestBook.

Truck is running ok but it sounds a little rough. I'm happy to replace the sensors for the peace of mind, and do a tune up as well. I emailed Nathan @ Discount Rovers and will order the sensors, but I want to make sure I am clearing the codes properly first. I've only owned the LR for 6k mi, so I don't know how old the sensors are. Carfax reported dealer maintenance to like 98k, so they should have been replaced, but....

Thanks a lot,

kip

I had a code 45 pop up after pressure washing my engine the other day. Vehicle ran poorly at best. I just kept drying and rechecking components until it seemed better. Been runnin fine for a week now with no code return. Not saying that your O2 sensor isn't bad, but keep in mind, on pre-96 vehicles an O2 sensor code will set if that bank is running to rich or to lean (45 is right bank I think). The connectors aren't to complicated just squeeze the sides and pull apart. Replacing O2 sensors isnt always included in maintenance procedures.
