xantia mk 1 1.9 TD rev counter sensor location

[aerodynamica]

Where is it located?

[citronut]

at the rear of the engine block just below the head joint pointing towards the flywheel,

.... above the output of the drivers drive shaft, go from under the car, and look up above the drive shaft..

Black Plastic with black wire comming off it... to backward trace, its a 3 Pin plug up top useually connected near the thermostat housing..

Miy TD has the grey 3-pin plug & socket fixed to the top of the gearbox. My rev counter usually works, but ceases to work at random times, for varying periods. I've given up trying to trace exactly where the problem lies

It will be the sensor for a couple of reasons..

Firstly they are magnetic, and also the end of the sensor gets crapped up with gunge and oil etc... and being magnetic may pick up magnetic swarf..

If you remove the sensor out , clean the end up and then push it back in BUT BE WARNED!! When pushing back in DO NOT push all the way back in!! What I do, is I start the engine, then i lightly tap it back in till the rev counter wakes up then a little bit more, then nip the plastic clamp back up

Thanks Paul, have tried removing the sensor and cleaning it up. Refitted it with 12 thou clearance from flywheel and it seemed to improve things for a while, but it then reverted to misbehaving again. Thought it might be the cable connection into the sensor, which is all sealed up, but barring a direct substitute, unsure how to prove this. Not sure if a continuity test would be a suitable

The connection breaks down with engine heat and replacement is therefore needed...

Here is one.. i actually bought one of these even though its for an xm and gave them an xm reg to get it and stuck it a xantia..

Hmmm - thanks Paul. It's a pretty hot environment where the sensor's located, so that sounds very plausible. I'll have a word with a friend who's just given a TD to a friend for parts/scrap. Guess mine had had enough with the mileage it's done (now on 186k, but yes I know I can't match your 110 )

Ive also a 1.9 TD awaiting resto with 240k on it too....

[aerodynamica]

Thanks folks - I'll have a look at it.

Basically the symptoms are that instead of pointing to the rpm reading on the dial it waves around the approximate rpm and sometimes chucks it altogether and goes back to zero. Once in a blue moon it reads fine though..

Same as above greame ... needs replacement as it is breaking up or down which ever you like..
