Anyone know the best way to remove the rear sensor from an early 24v.

Not done a early one, but I would have thought it would be same as a late one,
I use a socket designed to remove o2 sensor, and get from below and then struggle to unclip it (small hands) required

I managed with a spanner. But had to get the car on ramps, and go from underneath. Can't remember if I removed the crossmember for better access.

oh yes remove the crossmember

I know great store is made of these units working BUT mine were never changed ( despite being U/S ) for 19 years.
Fuel consumption was generally around 38mpg , more if driven carefully.
The ECU provides an optimum input in the event of 'no input' so no need to get too worried about those codes.

Early and late are in different places. Later ones can be accessed easily from the wheel arch but early ones are right at the back.
I already have the necessary socket but can't get a ratchet on it. I'll try removing the cross member.

I use a 22mm ring spanner, I think it’s 22mm. It is cut in half, disconnect the plug, working from the top, place ring spanner on O2 sensor, then I have a piece of pipe flattened at one end, place this end against the end of the spanner and tap with a hammer. 5 minute job.
