Playing with TBi, what amp rating was used in the in-line fuse. Thanks for the replies.

I just have the one heated O2 sensor. I'll check the resistance as you note but just for conversation here assuming my resistance falls within the value you offered and I have one 02 sensor it's somewhat safe to assume about 2 amps of draw if you add a little for the sensor getting warm and the resistance increasing.
Thanks
