VX Crank sensor longevity.
« on: 12 July 2009, 20:46:07 »
Crank sensors, new genuine ones from Vauxhall.
Wires routed well away from anything hot...


How long should they last?

I replaced on in Ljay's May last year.

Its not been running perfectly so took a look, found and fixed an airleak (top hat seal)

re-blocked the EGr with a proper lump of metal, cans melt through in no time.

Also, had a code 19, I check codes regularly, and it has only just appeared, will be monitoring carefully for a reoccurence before changing though, but really think they should last more than 14 months!

I'm touching wood!  ;D
Vauxhall fitted mine in Feb 2004 ..... so far so good.

There's a new one in its box in the boot though .... just in case!  :y  :y

It looks like I need a new one.  :( Hope it lasts plenty! Anyone know how long it takes to fit tho? and any guides for doing just that?!  :-/

Vectra Elite Estate doing good post-Omega service but still not as nice to sit in.

One last Omega on the drive, one Corsa on the lawn...maybe they'll go to a good home before too long!

Likewise I had one that lasted four months.  Boys said to make sure I use the genuine vs a third party this time.  Seemed vary illogical that the part would fail so fast.

Good Luck :y

5 mins, and there is a guide in the maint section, along with the alternate routing  :y

14 months seems short to me, there will be daily code checks for a bit  :y

i've had 3on my car in 17mths. first 2 were vx didnt last 9 mths between them. 3rd is a pattern. seems to be lasting  longer. i always try and use genuine parts but at over £60 each for vx's against just a tad over £38 for a pattern 1 that lasts longer. thinki'll use pattern from now on.

unusual to hear good results from a pattern crank sensor, normally horror stories.

do you know what make your pattern one is?

why is it V6 ones seem to fail so quickly? I have never touch mine *touch wood, or father tunnies.

It seams cam sensor is the more common failure on 4 pots, but i replaced mine 3 years ago.

often 'thought' to be heat from the origial cable routing.

this one is straight over, and down behind the abs pipes in the relative cool.

maybe crank sensor quality has gone the same way as the exhausts  :-/

wonder what the earliest 'original sensor' failure was. 

I know mine had one in the late 90000's  and that is still running fine at 130k

Vauxhall fitted mine, so I don't know what the routing was like before, but it's now towards the back of the cooler pipes in a convoluted flexi conduit.

I think that is most likely, exhausts we can physically feel in weight and design, and can see the changes.

With Sensors, no such luck. I guess we should try and pull one apart? An early one and a later one?

I suspect Vx are offsetting all the suppliers out there to the cheapest bidder

This might explain why we were scratching our heads over VMax's stalling issue. New crank sensor fitted, still getting code 19s, still stalling. >:(
