The crankshaft sensor reluctor ring is around the outer periphery of the flywheel, so the sensor itself will be mounted on the widest part of the bell housing. About where the starter ring gear would be.

thanks for the reply.......so I should be able to access it through the nearside wheel arch?

 

I've just had a look through my very expensive and difficult to read MGR Manual (only £40 from Amazon folks) and I'd say yes, it's accessible from the nearside. I suspect you'll be better under the nearside than working through the wheel arch (axle stands essential). The crank sensor has a lead and connector plug which comes up to somewhere near the battery box. If you can find that and trace it back to the sensor. It looks to be vertically below the coolant temperature sensor, which is at the RH end of the head.

thanks I'll have a look saturday morning

 

No need to jack up the car or remove the wheel arch liner........just lift out the whole air filter box assembly (2mins max) you will see the crank sensor and it is easy to remove from above..........

 

thanks pernix that sounds good
