Just back from Vaux main agent. I asked them to test my new crank sensor. Tested and OK, they cleared the code 19 and said everything is fine now - no stalling. Well that lasted about 500yds before it stalled again !! At the end of my teather now what else could this be I've given up on garages  (5 visits and still the same problem)......

has the 19 come back since they cleared the codes?

[Kevin Wood]

.. and how did they test the sensor?

It might measure Ok with a multimeter, but a different story in a hot engine bay.

As said, paperclip it and see if the 19 has come back. It was coming back pretty rapidly before.

Code 19 is back. Sounds as if I have to go back to Vaux, realy ****** me off now! Before I call them and rant and rave... does this mean that it is definitely a  dodgy sensor?  :-? :-/

Deffo a dodgy sensor....19 is a very clear one!

They should have cleared the codes and taken it for a drive....

[Vmax]

Yup. They said they had test driven it! My Ar**! I only traveled to the end of the road and it stalled. Right then, it's back to Vauxhall again! You would think that they would have sorted such a straight forward problem easily, especially as they told me that their Omega expert had checked it!!!

Right then here we go again    Went to Vauxhall and got them to check my car again. Finally, after 1.5 hours of waiting and arguing with various managers and mechanics, they agreed that my crank sensor was "probably faulty", they changed it and all seemed fine for a short while. I now have code 19 back again!! and the sodding thing is stalling again. When stationary and in drive It hunts, dropping between 500 and 200 rpm with the car lurching around before stalling. Also it sometimes splutters and dies when I try to accelerate away. it always re-starts on the first turn. It also takes three turns to start in the mornings. Could there possibly be anything else causing this? Could it be the socket that the sensor plugs into? As you can imagine I am rapidly losing patience with this car... :-/

I'd say it's still the ECU having issues with decoding the crank sensor signal. If it's not the sensor itself it's time to consider the wiring from the crank sensor plug on the loom back to the ECU - maybe the screening on this wire has come adrift and it's picking up ignition noise. Might be worth checking the routing of the crank sensor wire itself. If it runs next to an ignition lead which is breaking down maybe that's a source of interference?
