2003 v70 stalls very often. Parts replaced. Need advise

[antoniveb]

is that what I need?

or just sensor?

Shouldn't it show P0118 if this sensor is bad?

The codes you listed, I cut and pasted, state "Temperature sensor 1". (maybe this is integrated into the MAF - I don't know).

Regardless I would look at the temperature sensor in your picture. You can try unplugging it and see if you get the hard code (which you should as the signal would be gone) and see if the car performs any different. It may have a closed loop program or not built into the software for this sensor and use an average reading, like unplugging the MAF did.

I don't know enough about the various temperature sensors in the car, but the picture you post shows a brass colored sensor which a appears to be a temperature sensor by its location. You can try removing it and cleaning it off, check it with a VOM for resistance cold and warm (it should vary) either in car or in hot water. Can you buy just the sensor? Maybe pull it off a car at a junk yard? Look on it for a part number.

There should be another physical temperature sensor somewhere. Check them both.

What we know is your car has issues, you have chased most of them down and the problem remains. I have seen a large number of posts with similar fact situations where a temperature sensor ends up being the culprit and after countless repair attempts it is isolated.

Did you ever check the fuel filter?

P0113 is IAT ( Intake Air Temperature )

IAT is in the MAF sensor.
There is an error in VIDA for some years that mislabels the ECT ( Engine Coolant Temperature ) as IAT. This error includes the 2003 V70.

Ordered temp sensor and fuel filter. Thanks for all the troubleshooting and advises!

[antoniveb]

So far Temperature sensor replaced. Issue is still there.
Not sure it doesn't make a sense to replace fuel filter. Car eats gas well and doesn't stall when MAF is unplugged. Too well. Like 14mpg.

I probably going to check it for vacuum leaks at repair shop tomorrow and if it will not do I'm on the edge to dump the beauty.

Any chance the cat is melted or plugged?

[antoniveb]

Not sure, but exhaust looks and smells fine.
So, going back through all suggestions:
1 Vacuum Leak
2 throttle body
3 Computer

In my first post I mentioned clogged exhaust. My old S80 had this issue. Worth pursing as every other idea has been a miss.

As it is not burning oil it doesn't make sense unless something happened early in the car's history.

There are tools some shops have to measure exhaust output volume. At home solution is to pull the O2 sensor and start it up. It will be rather loud, the engine will code, but if it runs well it gives the answer. Also - with the O2 out one can use a mirror and flash light and get a decent look at the cat condition.

You are able to rule all of that out with DiCE/VIDA, while seeping beer (1 yields bad fuel trim, 2 has a test, 3 throws ton of weird codes).

Bad cat is not that unlikely.

What exact MAF did you put in? What codes remained active after you cleared them?
