If you place a voltmeter in series along the sensor's signal wire, you should see the output voltage oscillate between 0.4V and 0.8V (for RB26). If it is outside that range, doesn't oscillate at all, or the mean is not around 0.6V, then the sensor has had it.

If you have access to a Consult cable, that is 1000 times easier, as you need to check the sensor when hot (ie. scorch your hands trying to place the meter along the wire).

Hope that helps. If you're near Western Sydney I can help out with the Consult cable. Cheers.

If you jack up the car, follow the front pipes to where they are bolted to the dump pipes. The oxygen sensors are about two inches long and are screwed into the dump pipes. They will be the only things screwed in, look like a thick brass pen and have wires coming out the top.

It would probably be cheaper to take the car to Mr Nissan and have them run Consult to help you check the sensor function (and everything else whilst you're there) :P They'd probably charge 1h labour but you could save a lot of hassle with wiring in meters etc and it'd be cheaper than using a mechanic to hoist the car and have them do it. The Consult plug is in the drivers side fuse panel - ie. very easy to access :D

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
