I have a 2000 xterra 3.3 V6 that has started having an issue with blowing the 15A eng cont ig fuse #14. It controls the 02 sensor heater, but not sure whatelse it controls. I replaced the fuse and cleared the codes. It helped for a couple days, but the fuse blew again. Anyone ever have this happen and/or help me figure this thing out. It sets codes po135, po141, po155, po161. Which is all 4 O2 sensor heater malfunction. AThank you in advance.
