Engine died while driving, p0344 p0422 codes

[mschneider]

I was driving home in the rain today when all of a sudden I was without power in my 2000 V70XC.
I was raining, and has been fairly poor April weather for the last few days.

I hooked up the code reader, and it is showing a p0422 and p0344 codes.
The p0422 code is not all that unusual for this car, as I see it a few times a year or so. Usually when driving in heavy traffic, or in a high moisture situation. I get it once, then I don't see it again for months.

This time around though, the car is dead, won't start.

Anyone have any suggestions on where to start looking?
I wonder if it is an electrical or sensor fault.

P0344 - camshaft position sensor.

It fluked out on you. That's your problem.

The camshaft position sensor controls spark timing and injector timing. Without it, the car just doesn't know how to run.

You can pull one of these from a junkyard (it will have to be a 1999-2002 turbo model), or buy new ($$$).

Thanks for the info.

I'm trying to locate the cps on this model; there appears to be only one, is it on the exhaust side under that engine mount? Any trick to getting it out, I couldn't find a write-up for a 1999-2002 turbo?

Though I did find these posts/images:

If it is just removing the sensor from the bottom, not the housing it goes into, then that might not be so bad.

I was thinking I might replace the seal while I was in there, however that looks harder. Those ports to the right in that first image look like coolant perhaps? Assuming that block has to be removed.

Any thoughts on that?

Thanks again.

That's the one (first picture). The guy in the 2nd post is pointing at the crankshaft position sensor; that's totally different.

If the seal isn't leaking oil out right now, I wouldn't worry about the seal. It can be a pain to access.

Should be just those two bolts on the sensor and it'll pop right off. With a small swivel socket or 1/4" drive, you shouldn't need to move anything else out of the way.
