My car has been stalling intermittantly for a while now, and I took it to an import specialist(supposed), and told me I need a new camshaft sensor, however they are not 100% sure as they don't have a tech2 scanner. Anyway does this sound like a camshaft or crankshaft sensor issue? I have been told by another mechanic that my engine has no camshaft sensor, just a crank sensor but Saab lists that it does? I'm totally confused!? Any help will be greatly appriciated!

Details newver hurt anybody! ;)

Mileage?
2.0 turbo, 2.3 N/A or 2.5 V6?
Please describe the symptoms in detail. intermittant stalling isn't enough description for diagnosis. Does it happen on cold starts or after a short trip when you try to restart the car or coming to a stop? Or after filling the car with gas....
Details man, details. Help us help you :cheesy:

Sorry I was so vague, just stressed out with this. O.K. It always starts right up when cold, and doesn't usually stall until the end of the day (usually after work). Sometimes it catches itself and doesn't completly die,and I get that bing bing sound with no display in the s.i.d. It was running fine for a little over a month but stalled yesterday, and did not want to restart although it was cranking fine. This time I noticed that the main instrument lights were very dim or off completly when cranking while the other lighting (s.i.d, radio,acc,headights,turnsignals) were fine. I let it sit for about ten minutes, and all lights came up when I turned the key to on, and it started right up. By the way my car is a 1995 900se v-6. I hope this helps a little better. Thanks for your help! Also there is no hesitation before the car stalls, it shifts smooth and is powerefull, and I have a full tank of gas when it cuts out. thanks again

I'm sure the V6 dosen't have a crankshaft sensor?

It does have a camshaft sensor, take the plastic cover off the engine and look at the left hand side of the front bank of cylinders next to the cam belt covers, you'll find it at the bottom left hand corner.

Have a look at the pipes that lead from the flexy pipe just before your throttle body and head off under the inlet manifold to the idle valve, are they loose?

If you've removed that plastic cover from the engine, pull the spark plug cables out and see how much oil is on the plugs and cables, theres a couple of V6s on the forum that have died and wont restart due to oil destroying the cables, have a poke about and see what you can find...

The V6 does have a CPS (crank....). I cannot see how its failure, or a partial shutdown could cause stalling.., as then the fuel pressure needs are the least.
WOT - a different story - and a test is in order...

I put this in another post, but...

If anyone out there still has an issue with Stalling/hesitating, I fixed my ’99 9-3. I changed out the Crankshaft Position Sensor, the Throttle positioning sensor, and the rear O2 sensor. Nothing worked. What did work was replacing the EVAP purge valve, right under the cruise control module housing. Rockauto.com has them for under $70. Good luck!

I'll make this a favorite, titled "Stalling Solution".

These things do have to be carefully diagnosed and examined...millions can be saved...waste averted..

And, BTW, if a dealer replaced these items and the problem was not solved, would the customer still have to pay ?

Not in my day- the mechanic had to find the part that was malfunctioning and replace only that one...

Ok, I thought so, that's why I asked you if it happens after a fillup :cheesy: Common problem and there's an easy fix if it's indeed what I think it is.

If the problem occures again and the car was just filled with gas as well, it would be an Evap valve problem. Unplug the wire harness going to the valve (the check engine would light up but that is normal as you would have unplugged an emission system component thus triggering the light. don't worry about that). If the car goes back to normal, take off the Evap valve (AKA purge valve) and service it or replace it (it may also be a bad or cracked hose going to it).

I agree Earthworm. I probably could have saved some $$ going to a dealer/mechanic. However, in the end, I have accomplished two important things: I have four new sensors (which I doubt will fail in the time I own the car), and I know more about the mechanics of my Saab.
