96 XJ O2 issue
I have a 96 Xj with the check engine light on. I took it to autozone and ran a quick diagnoses. It indicated that the upstream O2 sensor needed replaced. I had that sensor replaced about 7k miles ago, but it was about 4 years as I do not drive it much. I have read online that the old Xjs will sometimes show the need for a sensor replacement but actually have a blown O2 fuse. I looked in my owners manual and could not find anything about an O2 fuse. Does the 96 xj classic have a fuse for the O2 sensor? If so, where is in in the engine compartment fuse box? Also if I need to replace the upstream sensor, should I replace the downstream also. The XJ has 105K miles
