A couple months ago I had to replace the CAT and o2 sensor in my 850 non turbo. Any one know the reset procedure from the "A" box. I managed to reset the service code but I need info on resetting code. It is probably the o2 sensor that started the code.

 

You should be able to reset it from the OBD-II port.

 

I don't understand, I have a 850 turbo 1995, and the OBD is unavailable till 96 ?

 

Some turbocharged 850s made in '94 & later do have OBD-II connector under the coin holder in front of the shifter.

Check inside the vehicle just above the shifter on the drivers side. There should be a coil holder and it says something about OBDII connector.
If you have the connector you can read and erase codes with a OBDII code scanner.
