Crank sensor 2.6 v6
« on: 20 September 2019, 07:45:02 »
Hi folks urgent advice needed.
Had poor starting and now the engine has cut out and won’t start. Scanner displayed with all the usual dash lights. Suspect it is crank sensor from other posts. Do we agree. Now I understand there are two types. Is this the case on the face lift 2.6. OR was that only the earlier 2.5

Thanks

Should only be one choice for the 2.6...

But...
ONLY BUY A GENUINE SENSOR FROM A GENUINE VAUXHALL DEALER THAT YOU GENUINELY WALK IN TO.   :y

It's usually heat that causes them to fail. Car stops, you wait for recovery, by the time recovery arrives the crank sensor has cooled down & so starts first time when the recovery driver tries.  ;D

Crank sensor failure on the V6 fall into 2 categories.

1) It simply wont start
or
2) Starts and runs fine, but as it warms up, the engine cuts suddenly and wont restart until its cooled a little


In both cases, sometimes, not always, you get early warning signs of a flicker of the EML, but its never brought on properly, or the car stutters at low revs.

When mine started to fail the rpm meter became nervous when idling.  Sometimes engine stopped, and after a while I could start again and contine driving. Does rpm signal come from that sensor?

And it must be a GM sensor bought from a bricks and mortar dealer. Not a "genuine Bosch" from ebay, or mail order from a non GM dealer...    ...the ebay route is just silly, and mail order from non dealers is risky.

Only a genuine GM part will do.

Not directly. It comes from the engine ECU.  Obviously the engine ECU on the Motronic units fitted to V6 Omegas is utterly reliant on crank sensor.

Many thanks folks. Ordered one today from a real dealer. Just got to wait patiently for it to come all the way from the motherland.

I had the same problem on 2, 2.6 Meegas. Rough as a badger's then wouldn't start. Once the engine cooled, it would start no problem. Only buy a genuine replacement, the Euro Car Prats copy didn't line up with the fixing bolt position.

And most likely would work, or at best, would work briefly.


Same goes for places like Autovaux and similar, who claim its an OE part when its not.

Not wanting to tempt fate, but I bought a crank sensor from ebay 2 1/2 years ago (kindly fitted by Albs) for £11.80 delivered and it is still going strong!
TB, if you ever want me to buy anything on your behalf, just let me know..... ;D
