Right, I changed the C/S back in August, admittedly it wasn't a "Genuine Vauxhall" part due to EPC being wrong but it was a Bosch sensor and identical to the VX ones. Obviously I re-routed the wiring too

The code 19 has never cleared from the paper clip test even though there are now no signs or symptoms whatsoever that there is a problem.

When Kevin tried to Tech2 it we couldn't get any communication from anything which ran through the same pin, including the stereo. Anyway, I've had the stereo out today and checked the wiring behind and can find no fault whatsoever... I'm popping down to see Johhnycboy tomorrow so I'll have another go with his "My Naff Code Reader".

Question is... Does crank sensor code normally have to be cleared? If not, would a dodgy connection on the radio (which we have assumed is causing the comms failure) cause the code to remain after the 20 or so clean starts? It's certainly had that... I've done over 11k since then!

Interesting, I'm currently scratching my head over a code 19. Sensor replaced about 8 months ago, failed 4 months ago , replaced again under warranty, now I've got a code 19 still showing when I paperclip. But when it previously failed and now I have never had any problem with the engine, its always run smoothly and ticked over nicely.

I'm just going to leave it for now see what happens

Genuine vaux sensor .

I think the code will clear after a number of starts. Not as familiar with the non-dbw ECUs but I believe that's the case.

It should also show up as "present" or "not present" depending on whether the original problem still exists.

It's an odd one regarding the diag line. I expected there to have been a previous bodge behind the head unit interfering with that!

You might want to try unplugging each device on that diag line until it starts working - but also have a look at the diag connector just in case someone has been a bit over zealous ramming a paperclip in and has damaged the connector.

We had a really good check on that when it wouldn't work :-/ :-/

I reckon it may have been a loose connection at the radio (I hope) as I know that had been interfered with because it was me

Can you remember what else is on the same line? Engine ECU, Radio, ?

Perhaps TB will pop in later and fill in the gaps for me

initially, I'd still suspect a dodgy crank sensor, esp as non genuine...

Pop it up one day, we'll clear it out, and see what happens then

From memory, radio is on pin 6 or 7 of diag connector, and display is on other. seem to remember the engine being on pin 7, but would need to check wiring.

Its in the book of lies I believe if you check wiring diags

[Kevin Wood]

Agreed. If it's still got a 19 there's something about the crank sensor signal it's not happy with.

My only other suggestion would be that it's picking up noise from another system. Poorly suppressed coil pack LT supply, breaking down HT lead or general noise on the 12v supply, perhaps from failing alternator brushes or rectifier pack.

Would expect other symptoms with most of those though. :-/

I remember we did check the diag. socket now. My guess is that something else on that line's pulling it down. I will have a look later and see if I can figure out what else's attached to it.

Don't have one of those... See little point when it's utter rubbish and I can get better, more reliable information from this forum

There is no point... [size=8]Other than the wiring diagrams.[/size]

Nah, its a useful little guide. If often 'dangle berries'

Im working in reading right now TB so could be a challenge but its not a bad idea (its very handy having you close by I must try not to abuse the service ). I guess its possible that I've just been unlucky and had 2 failures.....

It would prove for def if the code occasionally needs to be cleared after reapir.


As for the 20 starts thing, when my crank sensor let go, immediately upon replacing it, it reverted to a 31 (the only diag tool I had then was a paperclip), so I think it should show as fixed instantly.

TBH I would have agreed if it were a cheap pattern part but... Genuine Bosch, Identical in every way to Vx part (which is Bosch) and, more to the point, it's never cleared :-/ :-/

I wonder if the LPG RPM pickup is confusing it somehow???

I've never had a 31 out of mine, even before the sensor failed :-/ :-/
