Exhaust Resinator

graystucco · Oct 27th, 2004, 06:01 PM

I own a 2002 Nissan Pathfinder and my "service engine light" came on this past weekend. when I took it in to get this looked at, the service guy told me that it was my Exhaust Resinator, also called a front exhaust tube? (luckily this was covered under my warranty). The service guy said that Nissan put out a Technical Service Notice that addresses this problem.

Question is has anyone else ran into this problem?

another thing is has anyone had any problems with they're CD disc changer?

The exhaust resinator would not cause a check engine light, but my his description ("front pipe"), it's probably not the resinator. The resinator is usually in the very rear section of the tailpipe, if your vehicle has one. I would suspect that the catalytic converter may be the problem, or something like an oxygen sensor. Either way, I wouldn't expect a problem on a vehicle only 2 years old. What was the actual OBD-II code? There should probably be a P and then a 4 digit number, like P1234. If you can get this code, we can tell you what it is, or you can even look it up on the Internet.

Good luck,

thank you very much. I will call the dealer tomorrow and see if I can get this code from them.

There is a TSB on the CD changer heating up.
The TSB for the Ox Sensor is on the 2nd cat.

thanks for your response but can you explain what a TSB is and what it has to do with the O2 sensor and the 2nd cat? are you talking about the catalytic converter?

look forward to hearing from you. thanks

A TSB is a Technical Service Bulletin. News on parts that do things they aren't supposed to and how to fix them properly.

"Second cat" would be referring to the #2 catalytic converter, yes. There are two of them on your vehicle.

Also, it's spelled "resonator".

I agree with Jason that the resonator will not cause your check engine light to come on. Please correct me if I am wrong, but the resonator is there to simply improve the sound quality of the exhaust note. A lot of people mistake it for the "main" muffler, which is actually twice as large and is located further up the exhaust system (below the rear passenger area).

Also, to add to 88pathoffroad's comments, the nature of these TSB's is different from recalls. According to Stevens Creek Nissan in San Jose, CA, TSB's are actually intended for the Nissan mechanics which can be viewed as an update to existing repair manuals. Unlike recalls where the problems are fixed no questions asked, TSB-related issues have to be duplicated by the dealer first. That is, you take them on a test drive and you show them the problem. Once they duplicate the problem, it still doesn't entitle you to a free lunch. They still have to check if this is covered under warranty, and if not, you may have to out-of-pocket the expense. Again, so I'm told.

Here is a link to the TSB's for our Pathys:

In keeping my post shorter, you might want to check out my response to the thread "Just bought 1st Nissan - 04 Pathfinder SE." I had a similar experience with the problems you listed: check engine light (turned out to be a faulty valve) and CD player problem (CD skipping, replaced once by dealer).
