Hi Tunnie. yes its the one with the spanner through it.  Yes I can rev through 4000 rpm

Not cam sensor then, its odd that no codes showed up on a diog.  :-/

[Koomorph]

Called and spoke to official VX regarding which part number for the crankshaft sensor to order and they said that for the registration I gave them there are two:

90492006 - £82+VAT

and

90540743 - £53+VAT

He said both are listed as 2.6 V6 crankshaft speed sensors, the second one as a Y26SE engine.

He also said both look very similar and couldn't advise any further.

Any ideas how I could narrow it down further? Is the part number stamped on the sensor?

[Koomorph]

Could anyone advise why there seems to be a relationship with the crank sensor not giving the right signal (and car cutting out/not starting) when the engine get warmed up/hot? Leave it to cool down and it starts.

Seems to be fine on short runs and a cold(er) engine?

Any suggestions?

Cheers
Raf

Your dealer is telling you porkies, 90492006 is for 2.5 V6, 90540743 is for the 2.6. Yet another dealer who has not got a clue

You need to replace that crank sensor soon, the symptoms you are describing suggests its failing. Once it dies, the car won't start at all.

Get the second sensor listed, and steer clear of that idiot of a dealer!

That is one of the common failure symptoms. Mine was the sme when it failed - leave it to cool, car would run for another 10 mins or so (mine failed halfway down France, and in hot weather, so warmed up fast!).


Change the crank sensor, dont mess around

[Koomorph]

Thanks chaps - I certainly plan to change the sensor without doubt! It was just that I wasn't sure which one it was as both types/options were listed under my registration and he said he couldn't say which one until I brought the car in and they had a look.

And in this weather, I havn't had a chance to have a look myself.

However, if you're certain it's the ...743 then I'll just go for it and buy one. I was hesitant as I didn't want to get the wrong one and end up paying for both....

Hi Guys, I thought I'd give you an update on my unsolved problem

Since postingIve taken the car in to be looked at a local garage and they put it on their Diagnostic Machine.  They didnt see any fault codes for the Cam Sensor.  They found a bent pin in the Cam Sensor connector and straightened it.  They said that there were fault codes, which were Low Throttle response, Service Interface. They thought that the Gearbox Control Unit ( Its an Auto) and the ECU werent communicating, because a fault code came up for this too.  I must admit that the light seems to come on when the car changes from 2nd to 3rd gear.  The other things they said was that the pulleys/tensioners on the cam belt are very loose, so Ive booked the car in for a new cambelt and tensioners on Tuesday.  Im completely stumped.  Can anyone recomend anyone I can take the car to who has got a good code reader ( the one I bought cant find any codes) and hopefully help me get the problem sorted.  Im based in Swindon Wiltshire.  Thankg guys
