I have a Peugeot 406 1.9td and I have a problem with the rev counter. When it's on engine brake it drops to zero.I have read that there is a pick up sensor on the fly wheel but I can't find it.
Today I have looked under the car with no success.On the engine block there is a hole a two bolts near it that I think it suppose to be a sensor but there is nothing.It's on the engine block to the flywheel.
Something I can't understand that the rev counter still works.It only drops to zero when the engine is on Engine Brake,So I think that there is somewhere else from where the revcounter pick up it's signal.I hope someone can help me because I can't find anything.

If some one knows the location exactly or can take a picture I will epriciate very much

I think on these its driven via the ECU instead of the TDC sensor (which would be around the flywheel area)

Problem solved it was the Crank Sensor mounted on the top of the gearbox.
