Title: HBV and crank sensor?
Post by: Osprey on 08 July 2015, 10:57:25

Hi Gentlefolk

Noticed the telltale red dribble down the bell housing a week ago and made mental note to replace the HBV.

Then, yesterday, engine cuts out dead and won't restart, then starts and runs perfectly a few minutes later.  A few hours later, the same story.  Sounds like crank sensor beginning to go, although I can't check anything as the wife is hogging the Omega today.

Fair enough, HBV and crank sensor will be replaced - at least the scuttle only has to come off once for both.  But is it coincidence or have you ever heard of coolant from the HBV causing the CS to become burgered?  I guess it could get in at either the top connector or the sensor itself.

Just musing...

Coincidence.
2.5s are fussy about crank sensors, must be same make as original. Don't know whether 2.6s are similarly demanding.

Just unlucky timing really, you don't really want to drive with failing crank sensor. Ticking time bomb with an unknown fuse!

Oh crank sensor can be changed with scuttle in place  :y

OK, just coincidence I suppose.

No, I wouldn't want to drive on a dying CS either, but I'm at home supposedly recovering from illness. All this has been my wife, who is trying to drive back home after a time away. So it's either drive or put it on a recovery truck.

She called Churchill Rescue out yesterday and, despite passing on my message that the ECU won't enable the fuel pump until it gets a valid signal from the crank sensor, he pronounced that she had a fuel supply problem. After topping up the fuel, the car started and he decided that she had in fact run out of petrol (tank was over 1/4 full).  Face palm!

You can lead a man to knowledge but you can't make him think.

Oh, and cheers Tunnie, I dare say nimble hands can indeed manipulate the connector with the scuttle in place.  But my hands are fat and ugly.  And we'd best leave my face out of the discussion, if you don't mind.   ;D

But it makes life that little bit easier if the scuttle is off anyway for the HBV.
