"That one looks like a stiff breeze could knock him over. That tall drink of water with a silver spoon up his ass."

 

Best movie ever made.

 

His first night in the joint, Andy Dufresne cost me two packs of cigarettes. He never made a sound.

 

Anyone have direct familiarity with the NAPA awning? $129.99 - 20% (summer20) = $103.99 to Sept 30th. That's a cheap awning, but is it garbage?

Of course something like this would be easier to load/unload for a trip & would be more flexible. Similar price at $116.99

I saw an A-frame trailer like that recently at a campground and it looks like a pretty cool setup that isn't too pricey. It was being towed by an AWD hybrid Highlander. They hold like 30 gallons of water, but there's no grey or black tank and the grey just drains out of a garbage hose, otherwise I'd like it more.

 

Buddy's parents used to have one he'd borrow for trips to Hidden Falls. But then they sold it. I wish I had known, I might've bought it

 

My parents had one also, but Dad got tired of having to level it, then hoisting the bastard up and down was tough for him, they're up there in years. They sold it and got a more-functional pull-behind.

 

Need some advice. Dad's crappy Rogue is throwing another code. P0420. What's the best way to figure out if this is really the catalytic converter vs a bad 02 sensor. He's fine with buying new sensors but doesn't want to waste $200 if it's the cats. At that point, he would just get rid of it. It needs a lot of other work.

 

Swapping bank 1 with bank 2 sensors? See if it tracks.

 

This vehicle only has two I believe. One up, one down. The code isn't telling me which one would be the issue.

 

This, or gas and a match. Nissan, boooo

 

I'm normally for keeping a paid off vehicle but this thing is such a POS I think he should sell it.

 

Try searching on youtube and see if there's a bench level test. Here's one I found in about 10 seconds. There's probably a resistive value given in the FSM you can measure as well.

Hit a JY. There should be plenty of Rogues out there. Yoink both O2 sensors off one.

It's a Nissan, you might be able to get away with installing cheapo O2 sensors from the LAPS.

But needless to say, it's been my experience cats don't just "clog" from normal operation. They get jammed up when you do stupid shit that cause added particulate, allowing a car to run rich (think what happens if your a/f mixture is poor for extended periods due to failed O2 for a long period of time, or if you ignore fuel-related DTCs). This is one of those reasons why you want your O2 sensors to be functional, so the ECU can properly monitor/regulate a/f mixture. This is also why it's stupid to ignore O2 codes, I know some people are like, "aww, that's emissions bullshit, no big deal!" ... yeah, it is until it isn't. Oh, I've also heard stories over a couple decades now about how "buying cheap gas can cause cat clogs". I'm skeptical whether that's actually true or not.

Anyway, if that vehicle has less than 150k miles on it, and it's never had persistent DTCs on it, I'd be shocked if the cats are the problem. More likely the O2 sensors aren't reporting accurate data to the ECU.

 

Failing cats will also show other symptoms like an off putting smell, like sulphur and may also have trouble maintaining higher output scenarios. It's a Nissan, so it already stinks, and stinks at high output scenarios, so may be tough to tell.

 

It'd be the sensor after the cat.

 

I wish I knew. I've been fighting po420/430 for like 2+ years. Basically since I've owned the 03. I replaced the rear sensors and cats and that made it go away for a few months. Then it came back after passing emissions inspection a few weeks prior. So I replaced the front sensors and that got me to pass another inspection the next year, but the codes came back right after. Now I've got a po333 in addition to the 420 and 430. So I'm convinced it's a bad injector. Also because I've had to replace the same spark plug and coil pack twice. I already have a set of DD injectors waiting to be installed. I just hope that's the end of it.
I know the same high flow cats and 4 new denso sensors worked on my 06 when I got the headers installed and had po158 and po138. But the 03 has been a bitch with this CEL ever since the headers were installed. But the truck still runs great.

 

Yeah, you’d probably know if it was the upstream sensor. The vehicle would probably run like shit.

 

Before I replaced the upsteams on the 06, it seemed to run fine, but the CEL stayed on untill I replaced em.

 

Really? Hmmn.

 

He said gas mileage has dropped. He wants me to order cheaper sensors and we'll try that first.

 

Gas mileage dropping IMO is a sign of upstream sensor failure. But legit, it's best just to replace both on the bank throwing the cat code, which it sounds like is only one bank in this case.

 

I think it might depend on the particular code(s). Since I had po138 and po158, @empty_lord told me it would be safe to drive as is. So I drove from Houston to Amarillo and back and kept driving another 6 months or so til I had to change em so I'd pass emissions inspection. Mileage hasn't changed any since changing em either. They were fine until the headers changed the flow of things and I just replaced every part of the exhaust on the 06

 

IDK, I wouldn’t run my CATs rich for any prolonged period of time. That would eventually clog them. On the other end of the spectrum, if they were running too lean, that would cause them to overheat and degrade the insides. Neither of which are desireable.

 

I ordered pops the cheapest O2 sensors I could find. Rock Auto was cheaper than Advance.
