2000 S40 Oxygen Sensors S40-V40 2000

I have yet to find a good manual to show vacuum routing, let alone enough pictures for my liking. I've found that the best way to do it (although its not a quick way) is to take pictures and go one (or two) at a time, always making sure you know where every hose goes.. Some painters tape (i always have some lying around the garage it seems, perhaps its from the painting I should be doing...) marking the new ones helps you from doing the hose twice, and its not hard to remove (or really matter if you don't).

It will compensate to a point, but with a hose broken off the block like that you get multiple points of failure. Air seeps into the block, and air seeps into the hose (or out of either or both points, it can change the amount as it sees fit..) and gets into the engine. The fuel trim will only compensate so much before the codes go off blaming some component.

To monitor all the systems would almost double the sensors on the car. Which would increase the price of the car, significantly. Its not really a bad thing to always assume that a component is working (or always not working..) like a fuel pump. There's not really a need to put a sensor on it, if it works you get fuel, and if it doesn't you don't. It doesn't really degrade performance like many other components, which makes diagnosis easier. They also assume you do routine maintenance (I'm not saying its impossible to clog a fuel line if you change your fuel filter every year, and only get good gasoline, but its quite unlikely). There's just little to be gained in the operation of the car compared to the cost of implementing the system. Another problem is you'd have to find a way to avoid false positives, and to be honest, it'd be a nightmare.

I was lucky enough to make friends with a parts guy who 'loaned' me a copy of Vadis that they had no use for.. But I've got a haynes and a Chilton. Add those three in with the site and I can usually figure out what to do. I think a lot of the things that aren't covered, aren't covered because the components vary too much for the car, so rather than having 5 different instructions based on which model, they just leave it out... BTW, last I checked you could find Vadis on ebay for <100. Its probably just as shady as the copy I have, but if it works it works, right?

If you're not driving it "like its stolen," are you really driving?
