Title: Wrong crank sensor fitted.
Post by: Slowmo on 22 March 2012, 18:30:52

I've just replaced the cranks sensor on my 3.0 V6 1998 elite estate. The symptoms were the usual reported - ie. engine stops unexpectedly and won't restart. Leave for five minutes, restarts and runs OK.

The replacement supplied by local dealer is 90540743, which is the correct one according to the wise men of the OOF.

However the one I removed was part number 90492061, which I understand is for the 2.5 V6. The car has run OK without missing a beat for two and a half years to my knowledge. Will the wrong part have been significant, or are they near enough? Are they actually different?

Has anyone any experience of using the wrong crank sensor like this?

Peter

They list 3 crank sensors for the 2.5/3.0. From the looks of it your old sensor was used midway through the build run and the new one was used towards the end. So I can't see you having any issues

I stand corrected. So it will give you issues or is that may give you issues?

Thanks for the info. The original sensor 90492061 is a seimens one, and looks identical to the one in the link photo.

The new one, 90540743 also looks the same, ie. doesn't have the metal 'bit' in the centre. I shall keep a keen ear out for any problems with the new one.
