for everyone following my situation, my 850 turbo was sucking fuel like a truck, found that the front 02 sensor had been pulled out of it socket. after finding the wiring diagrams i put it back together and figured all was good . the sensor didnt look old but i have no idea of its history. thismorning after just over 100km of fixing the wiring it threw me a heater circuit code and a low voltage code. it never threw a code when the whole thing was unplugged. do i just change out the sensor and see were it goes or clear the codes and see were it was a delaid code from before the fix.

when you screwed the sensor back in, did you disconnect the battery and do a reset then? Although, if it was completely out of the cat, and didnt throw codes then... I'd suspect that reset or no, the O2 might be bad.

Yes, just replace it.

it was not actually out of the pipe at first i meant the harness was pulled apart. i took the sensoe out to change it when i noticed the wiring hanging there so i fixed the wiring and put the old sensor back in because it didnt look old but i have no idea how old it actually is.

ok. new ntk 02 sensor in place. wiring sorted out"i think" put the torn out terminals back in the exacy way the wiring diagram asked for and was reconfirmed on this forum. my datastream on my scanner does not whant tp tell me if it is working or not so i guess i will just see what the milage is after 100km.
