stalled
« on: 06 February 2018, 07:30:55 »

While pulling up to my drive yesterday i knocked it into neutral and the engine went splat. Never had that, i then reversed into drive and while doing so it stuttered and nearly stalled again. Also when at my folks i went to start and it just churned and churned and never started. I then turned key off then back to starting and it went. It did do this a couple of weeks ago but thought cause i had been lying fora while and in the cold. Seems there is a problem developing, what can i check, is this a known problem? I seen flashing spanner while trying to start it.

Currently have the p0150 or whatever it is code for O2 sensor, which is going to get looked at soon and exhaust change. It's drive by wire 2.6 v6. Done pedal check, seems only O2 sensor one and no others.

Update: just read its likey crank sensor, much are they from vx and does anyone have part number? Now i think on it i remember reading about this a wee while ago.

p0150 relates to the mixture being out, the symptoms you have also tend to point towards a potentially failing MAF.

Can you read the live values for air flow and the learnt values for mixture?

Crank sensor should be showing a code if its an issue.

I bought this for my 2.6 back in  February last year; not sure if they still have stock, but it was a steal at 11.80!

If it only requires a digy meter yes, is there a guide to do this?

I remember that. I bought one too, on your recommendation. I thought later you planned to replace it with a genuine Vauxhall crank sensor, and said you were going to. So it's a still working perfectly! That's good news. I remember six years ago I had a crank sensor fail on my 3.2, and bought a cheap replacement from e-bay. It's still running well.

I have the impression that on the 2.5s it is vital to buy genuine Vx crank sensors, and even then you need to get the right one - Siemens or Bosch.

You are right, Terry, I WAS going to buy a posh one, but as it is still working fine.....
Now, don't let Sod's Law hear that!

Maybe you can remember the comments on here regarding a common failure mechanism? My poor memory thinks that it had something to do with the connector rather than the sensor itself, and/or temperature issues due to proximity to the exhaust?

Would anyone know the part number for the crank sensor as there is apparently a number of different versions? Could I tell from chassis number or something like?

2.6/3.2 should all be the same... Plug is easy enough to check, being at the top and all.

Is it not buried down in the bay somewhere? Not seeing it after having a look top down there. A bit concerned it's not showing crank sensor code as mentioned by user fuse 19 above. I tried starting it there, not been run for about 3 weeks, and it ran for 2 secs then just stopped dead with flashing spanner light. Started up and ran ok afterwards tho.

Bought a genuine one[from main stealer]just over 2yrs ago and 60 ish seems to ring a bell.The sensor enters the engine down by the oil filter-one torx bolt[an 8?] holds it in,then as DG says electrical plug is behind right hand[UK passenger side]head near multi ram solenoid.

In my experience the crank sensor DTC rarely gets raised  on a 2.6 or 3.2. Never seen it on any of mine and had two crank sensor failures.

If Fuse 19 is advising MAF, then I would be looking there before anywhere else. Unplug the MAF and see if the symptoms change.
