Hey whats up guys? Just got a 05 Path on Sat. I really like the truck and am impressed with the styling and power. However today the "service engine" light came on.
I took it to schucks for a diagnostic and it pulled a p0420 code. From all my reading it sounds like I got a cat out, or possibly an 02 censor problem. I have been reading about laws requiring companies to extend the warranty on some exhaust parts including cats to 8/80000. (I have 54XXX)
Is there any truth to this, and how do I go about getting the work done? Do I need to show proof of a failed smog test or something.
Since my first fill (Sunday) up my trucks computer is telling me that I am averaging about 8 miles a gal. Could this be the issue?
Something is telling me the power-train warranty is going to be money well spent.
I am going to check the coolant tomorrow just to see it there is any issues with that.
Hope this is the last of the issues for a long while.
New member, and new problem.

Im not a mechanic but in playing with my other vehicles in the past, I would say the O2 sensor is likely the culprit for the poor MPG's....unless you're driving with Gravedigger's tires, buts thats probably not the case, right? 
Perhaps a good dose of Sea Foam or BG 44K could help clean up the system. The O2 sensors can get clogged up and throw the entire system off. Give it a whirl....

Do you a good picture to post showing which line to use? I want to do it on this new pathfinder just for a a little fall clean-up! I have done the procedure in other vehicles of mine but I an very new with this vehicle and Nissans in general.disallow wrote:The brake booster vacuum line is the best way to get this stuff into the engine.
Thanks!
It is very easy to find it is connected to the front of the brake booster. Remove the clip and then place the pipe - less the clamp into the bottle of sea foam - it will suck it up no problem. I regulated the amount of direct application by pouring some into a old/clean can - I was amazed at how strong the vacuum was, it lifted it out from about 2 inches from the liquid surface.
Don't do the throttle body unless you want to go through the reset operation - dump rest of the can in the tank.
good luck - hope this does the trick.

If you are looking to have it checked then I would say leave the treatment till after - the treatment cleans carbon and crud off the valves when injected via the vacuum pipe, through the tank it cleans the pipes and injectors.
I would do it and then i it throws a code - they can see it Saturday.
It is undetectable by the dealership.
Hope it covered under warranty.

Thats what I figured to do. I did the Seafoam and then went to Oreilies and cleared the code. So far it has not come back on. I would be stoked if this was the end of it, if not I will just have them go check it out.asgard wrote:If you are looking to have it checked then I would say leave the treatment till after - the treatment cleans carbon and crud off the valves when injected via the vacuum pipe, through the tank it cleans the pipes and injectors.

I have a picture of it, I am going to post it here once I find out how.135zeus wrote:Do you a good picture to post showing which line to use?

Ok here is a link to the picture. Its circled in red. I will tell you that you should be carefull when romoving the line. The plastic part seems very weak. Support it while you take off the hose. Don't break it.

I used it on every car I have ever had. I actually took a smog test before and after seafoam on my eclipse gsx (AWD Turbo) and the difference in the test was palpable.Fookn4x2 wrote:So is seafoam something everyone recommends? I have a 07 with 104K never had a problem other than the crappy suspension sway and the squeaking when going over bumps. Should seafoam be used for regular engine maintenance?
The only things you should be aware of is that it can expose leaks. Sometimes there are leaks that basically seal themselves (oil leaks in particular) and this product can strip those patches and let you find leaks especially with high mileage cars.
Secondly there is something called Hydra lock. Don't use too much in the air vac line. Do some research on that. (I will not be buying you a new motor).
Great product, plus its always a funny reaction from bystanders. Look up some of the seafoam videos on youtube.
