I have been having the MIL on, code relates to post cat o2 sensor heater, i investigated today and have found the lambda is not even plugged in and just have a loose plug from the post cat sensor but cannot find any spare plug to plug it into in the engine bay. It was not on its original mount between air filter and ecu but just hanging. I have remounted it but now require the plug/socket to plug it into. Can anyone tell me where abouts that said plug/socket runs from in the engine bay so i can trace it back to its roots please?

Look at the loom from the bottom plug of the ecu. The lead/connector is about two inches from the ecu plug.

Great, found it, thank you. Was well tucked in!

The only thing that went wrong with my Jaaaaaaag, with the exception of a CCV rubber pipe replaced under recall, at 75 k was these poxy Lambda sensors. Front upper and rear lower failed first on heater circuit, so I decided to swap them all out. The rear upper was a real joy, giving fond memories of comparitively easy TF engine access. There was about an inch and a half between the sensor and firewall, had to be done by feel.
