Help NISTECH...Bunch of trouble codes.
sw/v and tp/sw just turn the key on engine off, and push your gas pedal to the floor the release it if the fuse didnt blow thats not it. the sw/v(swirl control valve) will also change under hard throttle. have you checked the connector for moisture or corrosion in your right kick panel yet. thats is a very important starting point. key off, unplug it and look inside the terminal area.
yea I would take it hit up by email and I'll give you a mailing address. I appreciate it. [email protected]
CD is on it's way. Should take 3-4 days, parcel post. Sorry but I cheaped out. I haven't blown a fuse yet and i haven't checked my connector yet. My car all of a sudden started running like a scalded dog the other morning and has continued to do so since. I figure that it went into ready mode and put in a better fuel map instead of a safe mode one. Can you verify that? I would love to go ahead and get my emissions done if it is ready to go.
so just tell the emissions guy to check the monitors and see if there are any codes and if not, go ahead with the emissions test?
Does this thing actually change maps when it hasn't gone into ready mode? Like a safe mode kind of thing?
The performance difference is quite obvious.
There is a copy of the newest acrobat reader on the disk. for the best performance on the documents since they are quite large, install the new reader and copy the documents to your hard drive. the fwd.pdf file in each folder is your quick reference section to link to all the others. the table of contents rocks on this set of books. you will have a lot of info at your fingertips now. but the most important is the 98 fsm, of course......hehehe...

yes have him make sure your moniters have completed. That is the main OBDII difference from OBD I if they plug into your computer for the emissions test that is what they are looking for. I dont know how many they require to have completed to pass a emissions test but here its all but 2 of them have to have completed. If they have completed and there are no codes stored tell him/her to run the test. Yes there are 2 modes of operation with the computer control of your car..normal control and fail safe. Fail safe your car would lack power most noticably. they will go into fail safe only for a small hand full of reasons. If your car appears to be running good I think your ok.
Actually, my dealership was very forthcoming about not being able to find the problem immediately. Props to Sutherlin Nissan at the Mall of Georgia.
The car passed emissions today. So I am going ahead with my header and new cat arrangement soon. Just got to order the cat and the gaskets.
If the fuse blows again, I will take note of the conditions under which the fuse blew and check M63 at that time. Otherwise, I am just going to drive the car normally. I may get one of those cool lighted smart fuses to put in that slot for easy recognition of a blown fuse.
NISTECH thanks for all your help, your cd should be there soon. I may ask you some more about this if that fuse blows again.

Ok so check this out. I have been talking to the original owner of the vehicle and here is a portion of the email:
Never did get the truck fixed but I did get a 350ci for it but its just sitting there waiting to go in. and lately I'v been looking for a new car more than likely a protage 5 but we'll see what happens with that. And on that o2 problem not to sure personaly but Reagal nissan did the work on it and oridganaly that was what they told me the problem was but then they said there was something wrong with the computer causing a short. They told me that they had replaced the computer but thats all I know about it. ttyl Stephen

It seems that it wasn’t actually the problem and there is a intermittent electrical issue on the same circuit as the o2 sensor that causes the fuse to blow and then the car starts throwing codes. Interesting stuff, I have been trouble shooting it for a while now. Other than that, I absolutely love it.

So what do you think? Talk to the dealership that worked on it? Get the service records?

no no need to take it back I honestly dont think its the ECM or it would blow the fuse all the time.. after you played with the harness the fuse stopped blowing so I really believe its a harness issue. Getting the service records though is not a bad idea its always nice to know the history of the car.
Is your car blowing the fuse again?
