4 error codes reoccur regarding O2 sensor heater circuit. First occurence also showed gas cap problem. Changed that and that code dropped off but no luck on the O2 sensor errors(all 4). I forgot.15amp fuse keeps blowing the circuit. I replace the fuse, clear the codes and drives fine. It's when I shut off the vehicle the fuse blows. I changed the purge valve but it wasn't fixed. I checked/reseated the O2 sensor connections and for a couple days I was ok. Just a matter of luck? Then. Blown fuse. There was still a slight amount of pressure buildup when I released the gas cap. I'll try another cap. Maybe it's a coincidence. Bad cap. But could I be that lucky.
I saw that another gentleman's posting and he has the same error codes and symptoms.
What do you make of this? I wonder if he got his fixed and what was it? No emissions testing here in KY. Any suggestions would be appreciated. Thanks
How big of donation $$$$ are you looking for? I must have overlooked it in the literature. I'll look again. I have a '93 Nissan with a similar problem.
have the same problem?
