Xantia 1.9TD crank sensor replacement

[flyingtele]

Hi everyone, I have a 1998 Xantia 1.9TD and the tachometer is dead. Am pretty sure it is a faulty crank sensor, but having looked carefully I am unable to find it! I have searched the net and this forum trying to find out where it is located, as I am sure others have asked the same question but couldn't find anything. If anyone could tell me exactly where it is located or even better post a picture with its location circled, I would be most grateful. Does it attach to the block block behind the flywheel, or is it on the transmission case near the flywheel? Thanks in advance

It may be that the alternator drives the tachometer. The HDi engine needs a far more accurate measurement, so there is a crank sensor, but for a mechanically driven injection system it doesn't need that accuracy. However, I feel certain that somebody with far greater knowledge that I will give you a better informed answer.

Oh, to the forum, by the way.
