Does anyone possibly have part numbers & distributor info on TB48 O2 Sensors? I think Bosch have units for the TB48??
I have also read on the Australian forum that the front & rear sensors have different part numbers???
Any help & advice apreciated

Re: TB48 O2 sensors
I notice that the old sensors are 3wire & the new are 4wire, how do you work around this?jonathan wrote: ↑18 Mar 2021 13:26 Hi JP, I think I posted the part numbers somewhere in this thread when I replaced mine viewtopic.php?f=48&t=6975

Re: TB48 O2 sensors
Looks like the 3wire earths through its own body & the manifold & 4 wire uses a separate earth wire.
I am very challenged when it comes to wiring, so please correct me if I am talking kek...

Re: TB48 O2 sensors
I don't recall exactly, but this is what I did back then:
“One then cuts the plug from the old sensor and connect it to the new one. There is a kit included and instructions. So the extra grey wire on the new sensors are apparently external earths and I joined the together and connected to the body. From what I can gather the two white wires are for the heating element, which ensures that the sensors work correctly before the engine reaches temperature. Out of curiousity I tested and compared old and new sensors. On the new ones I could get a reading between the two whites, but not the old. Which may or may not explain the heavy smell of fuel I got when starting cold.”
So don’t worry JP looks like you're on the right track
