tacho rev gauge not working

Hi, I have purchased a 2001 HDI partner van which I am pretty impressed with
so far.
Anyway, the tachco is not working but seems to flicker when first started
and then nothing.
Anyone any ideas as to what these tachco's use as a signal pickup and what
the problem may be, fingers crossed its just a loose wire

Thanks in advance
Gary

 

Check the multi plug . and the sensor gos into the back of the gear-box
and pick up from the flywheel.i had this problem on my 405.i had to cut
the plug off and wire the wires together . i have got new unit but like
always have not fitted it yet.

 

Many thanks Chris, I shall crawl underneath and have a look tomorrow.
Cheers
Gary

 

Why wait till sat or sun to do the job.get a torch and have a look in
the dark hahahaha

 

In my younger days I would have done, I'm even a little bit tempted to now ,
but I think I'll wait till daylight (oh what the hell where's the torch)
cheers

Well dos it work now?

 

I ended working for most of the day, so I have still not had the chance to
crawl under it yet.
I will be doing it tomorrow though as long as it not raining that is.

No sunny day for sunday so you can do it and get a tan aswell hahahah
good luck..

 

well, no luck with the rev meter, I have unplugged and re-plugged in every
connector that I could find, with no luck at all. I have managed to cut my
fingers in god only knows how many places. Do Peugeot design those razor
sharp bits of plastic under the bonnet on purpose to keep the home mechanic
out of the engine bay.
I think I will stick a time clock over the top of it. One thing I have
noticed though is when I turn it off I get a sort of "grrrrr" noise for a
split second from behind the rev gauge itself.
I did give it a filter and oil change while I was messing about, so not
all a waste of time.

Did you find out where it went into the gear box? it could be that end
not in far or to far in ..

 

I believe I did find where it went into the gearbox, although I can not be
100% sure.
Not really a lot of room in the partner engine bay to get your arms in, but
I'm am pretty much sure that I found it. I just got to the stage of
unplugging and cleaning all the connectors that I could find in the end.
The van also has a very very very bloody annoying sort of whistle or high
pitch hum it happens when you very gently put your foot on the accelerator,
push it down harder and the noise is gone, cruise along at 60 with your foot
just on the gas and the whistle or hum is back, it does it in neutral and
when standing still so its nothing to do with gearbox.It just seems to
happen at certain low revs, if the bloody tachco worked I would know at what
revs. I am going to have to bite the bullet and take it into Peugeot and see
if they no what the whistle or hum is.I will get them to sort the tachco out
while they have it in. Its very faint but its one of those noises that once
you hear it you pick it up all the time. I am very tempted to park the van
in a field and set fire to it if they cannot find the whistle.it really is
driving me bloody nuts. Otherwise if all else fails then a very cheap HDI
2001 partner van will be on e-bay, I recommend it to those that cannot hear
high pitched whistles.

 

is it turbo? also it could be a pipe sucking in air or letting air out.
what about your fan belt is it tight?my 405 has got a very strange noise
but its because i got to replace the fan belt.spray wd40 on it and see
if the noise gos.i did on mione and it stopped, so i know its the belt.

 

Hi Chris
Its definitely not a turbo whistle, I drive a Citroen synergie so I know
that sound very well.
Its more of a tuning fork sort of whistle / hum, bloody hard to explain
really. As soon as you point it out to anyone they can then hear it all the
time. I have a feeling its coming from around the diesel injection pump
area, although I am not sure.
Apart from this and the tachco not working its a brilliant van, it drives
like a rocket for a diesel and pulls like a train. I will try and pop into a
dealer tomorrow if I get the chance and see what they say. The tachco I live
without , but the bloody whistle at low rev's in the background is another
matter.
I'll let you know how I get on.
(never had all this electronic gubbins in my old 205GTI )

WOOOHOOO I have managed to find the whistle / hum
it turned out to be one of the metal fuel pipes acting like a tuning fork at
certain revs
The cure was to place a piece of wood on the pipe and hit it with a hammer.
Hum gone. It was that simple, only took me 2 days to find it. At least I
can now keep the van and maybe even enjoy driving it.
As for the tacho I have booked it in for Friday morning to get it looked at.
I hope that it is the pick-up sensor connection like you suggested and I
have just missed it.
I will keep you posted on the findings

Do you really need the tachometer? We never used to have them and drove by
ear and seat of pants. I'd be inclined to save the money myself.

 

Hi Keith,
To be honest, no I don't need it.
It just gets on my nerves that its fitted and does not work.
I'm not really sure why they started to fit tacho's to diesels anyway. As
you say I have done many thousands of miles with out the aid of a tacho.I
suppose they fit them so people like me waste money getting them sorted out
when they pack up.

Cheers
Gary

 

You dont need a rev counter just wait till the engine dont go any
faster.or wait for a BANG.. HAHAHAH

 

Gary
Check the alternator bearings.

Thanks to all who suggested places to look for the whistle / hum
