Do a search using the forum. Theres loads of threads about it.

it will be at the bottom of the engine, drivers side (if you are UK), near the oil filter, and oil pressure switch. Its a plastic coated sensor pointing towards a groved ring.

Doubt its your problem though.

:yeahthat:

low power cant be crank sensor.

Probably just because its the 1.4.:devil:
