Default Emissions fuse

Does anyone know the location of the emissions fuse for a 97 850 T-5? Thank you!

What exactly is an "emissions fuse" and what is it supposed to do ??

Have you checked the owners manual or the back of the fuse panel cover under the hood ??

I am trying to determine why I'm getting code of P0245. On the Matthews Volvo forum, a person had the same problem after installing a new 02 sensor and determined that is was a blown emissions fuse. I just had an 02 sensor installed so it may be the same problem but I, like you, have no idea where the emissions fuse is. Thanks for any help.

I went back through the listing of the fuses and relays. I don't see anything that relates to the "emissions system" or it's components. Nothing for the O2's either. From the wiring diagram it looks like the sensor circuit and heater circuit come straight from the engine management computer and have no fuse in line. ??
I don't know.

You best bet is to get the light reset and see if it comes back. If it does you might want to try and contact that guy who said he changed a fuse to cure the problem and ask him what fuse and where it's located.
Wish I could do better.
