Where'd you get that clamp? 

I've not seen one of those for years!

Car boot sale, Andy......TBH, all my tools are 'donkey`s' old; they were better made back then!

Pin vices and pin chucks seem unsaleable these days.....I use them for model-engineering projects.

debs if no-one has got one spare i will pull a known working one off of one of my migs tomorrow for you 
only borrowed though 
pm me your address and i will get it in post to you 

edit---after checking plug of course 

[jonnycool]

Sorry Debs, been a bit busy - mine is the same as that, I can get it in the post in the morning if you want, just tell me if you want it 

[Debs.]

Thanks to the kindness of OOF members: I now have two crank-sensors (one is a 'known-good' on loan as a reference).
The pup-mobile was a non-starter this morning (as expected).......so, I fitted one of the new arrivals, cleared the stored code 19 and the car started and ran well, but something interesting has surfaced upon comparison of the three sensors: mine (the non-starter) was bought new, 5 weeks ago from my nearest VX dealer (Lookers) it was supplied sealed in an official-looking GM parts bag, but seems markedly different in form from either of the two which OOF members have sent me.

Look at the picture below: the obvious difference is the metal 'pip' on the face of the sensor (both similar) which are labelled Bosch....Whereas, the faulty one I bought at the dealer is labelled GM Siemens, which has a completely-smooth black face to the sensing head.
Upon measuring the GM Siemens sensor, it is 1.112mm shorter from the flange face to the sensor face than either of the Bosch units.

...might I have been sold a GM fake/cloned part?

[Kevin Wood]

Hmm. Spacing it further from the reluctor on the crank will reduce its' sensitivity. Maybe this, rather than failure of the part, has been your problem?

Could be the Siemens part is for a different application and has been incorrectly cross-referenced?

It would be interesting to see if the waveform at the output of the part meets Vauxhall's specifications. Maybe the dealer would care to measure it (free of charge, for thei own quality control purposes) and take this up with Vauxhall?

'Cor blimey! Look at that pig go! Delta wings and an afterburner on it!

Hi Debs

There are two listed for the Omega with the same plug, can you get a pic of the heads of the sensors and i'll be able to let for sure

cheers

Ah-ha!....the "thot plickens"! 

Will do, Andy!

Ok, here are crank sensors: the one pictured on the left: ID number 90 492 061, is the one supplied by Lookers VX (Wallasey) using info that they asked-for: registration number/M.Y and engine type etc. of the pup-mobile......the other, is one of the two sensors sent to me by OOF members: both of those Bosch units share the same ID number 0261210......all three, have exactly the same fitted-plug and cable length.
......Have they sold me the wrong one?

[Jimbob]

Excellent news, hope thats the end of your problems, just the VX battle to go...

[omegod]

Wouldn't surprise me if they sold you the wrong one, dealer system showed mine to be the rectangular plug. Found out months later when stranded in the middle of a busy junction that what I had bought as a spare was most definately not the right one .

I am still not welcome at that parts desk after resolving the issue

Hi Debs

Ok the one you have listed as 90492061 is listed on EPC for use on X25XE Engine but it also say that range breakpoint information is not available which means the sensor was changed at some point during production but GM can't pinpoit at what chassis/engine number they changed them, this is why sometimes we have to go by guess work.

The other one in your pic is part number 90540743 and is listed for Y26SE, X30XE, Y32SE again with the above listed as well.

All i can say is if you have the oval plug sensor then also check the mounting part of the sensor head, if you look you will see that the first one has a slopped top and no reinforcement to the fixing plate/bolt hole.

On the other sensor it has a flat head and two small triangluar reinforcements to the fixing plate
so you need to change like for like and then you should have a problem, can't say if this works with pattern sensore though

Hope that helps and you can get sorted

Cheers

Thank you very much, Andy.....that`s EXACTLY the info I needed; I`ve been down to the dealer and (of course) his EPC said "No" ......but, after a looooooooooong discussion about them not being able to do much without a TECH-II session (his inference was that the part that I have already, is 'faulty', not 'incorrect') the parts chap eventually agreed that there might be a possibility that the 2.6/3.0/3.2 sensor is the one that I originally had from new......so, he`s ordered one in, to compare with my original dud one......Awaiting a call from him when the part arrives.

[Kevin Wood]

This is very interesting information. I've come across one or two cars in the past that have had persistent 19 codes present, and occasional stalling, despite new sensors fitted. Never did get to the bottom of any of them. Sensors OK, wiring perfect right back to ECU.

[albitz]

There are also two different types of spark plug listed for the 2.5 V6,the later type being quite a bit more expensive than the earlier type. Ive no idea what the difference is between the two.
