Part ID.

Hi, having problems, narrowed down to possibly Lambda sensor?

Stuck in tight, hammer and chisel job, even then the reducing bush came instead of the sensor.

Does anyone have the correct part name and or number for it please?

The nissan manual just says it's a lambda lock nut. Can't seem to find a part number. Was it threaded in? Or pressed in

Threaded in, got that out with Lambda still in situ, got the whole in a vice and managed to get the lambda out, 12 inch Stilson wrench, really badly crossthreaded ! Botch job.
