407 Tyre Pressure Monitoring System

Does anyone know how this works? I looked around the web - Wiki has a
good section - but could not find how the Peugeot system works.
Presumably there is some sort of sensor in each tyre?

 

Yea its called the police, they seam to tell you when your tyres are
not good .

 

This web site gives you a cut away diagram as to how the sensors are fitted
in the wheels

these are also the ones fitted to Renault so its a good bet that Peugeot
would use pretty much the same.

The ones on Peugeot are incorporated in the tyre valve and very
compact. Works on the same principal though. When you change one they
have to be learnt to the ECU via the dealer diag tool.

 

Does this mean that when I need new tyres it's a dealer job?

Yes. Or a very clued up tyre place but they're like hens teeth.

Thought so, suspect the receiver is programmed through cars computer.

 

Is it necessary to replace the valves everytime you buy new tires?
I know that shops do this as a general practice, but is it really needed?

Don't know. Not sure how long the lithium batteries last - bet you need to
take the tyres off to sort that - and if you have flat batteries the car
whinges.

Errr no. You can go to any tyre place. As long as they are aware you
have monitors fitted the tyre is changed in exactly the same way. And
you don't have to change the valves every time you change a tyre.

 

I just had a close look at my tyre valves and they seem to be on
metallic stems screwed into the alloy wheels. this the first time in
many may decades that I have not been able to see the rubber valve
stem.

Presumably this assembly is unaffected by a tyre change? (We are
talking tubeless). Presumably the monitoring gear is built into the
alloy wheels somehow?

(I am suffering a form of culture shock - I mentioned the rear
proximity warning beeps in another post. Now every second vehicle I
see - any make - seems to have those sensors spaced around the rear
bumper)

 

When I asked at my local Costco [which appears to have the lowest
prices that I have so far seen for these] they said it was no problem
but they would not rotate the tyre.

 

The monitor is part of that valve. The whole assembly is pushed
through the hole and held in position with a nut. As long as the tyre
changer is aware there is a monitor fitted and doesn't lever the tyre
off in the vicinity of the valve!!

 

I often wonder about over-gadgetting in modern vehicles. In the nine
years I had my 406 I only had one puncture - picked up a nail and I
did not need a monitor to tell me I had a flat (though the vehicle
sailed along pretty happily - it took me a few seconds to work out
what was going on; but the tyre was a write-off anyway). I gather the
development of these monitors may have begun as an over-reaction in
the US to instability problems with
suvs. There must be five of these monitors on my 407 (presumably the
pressure in the spare is monitored or what?) each costing, I gather,
about as much as a tyre. In my early years as a driver I heard scare
stories about crashes caused by sudden deflation of front tyres (blow-
outs they were called). Yet I have spoken to a few people who actually
had front 'blow-outs and they reported no special difficulty - nothing
frightening.

Electric windows are another example. In a dozen or so vehicles, most
of which had manual windows (my 1989 F150 is still going strong) I
don't recall having any problems with window winders. Come to think of
it, there have been a dozen or so posts to this group about electric
window problems (usually related to resetting the ECU).

Motorised seats I like - especially ones with two memories, like my
406 SV. And side mirrors.

I can confirm that it is no problem. I have had three of the tyres on
my 407 replaced at different times by my local tyre and exhausts
outlet, and there was no problem. You can even drive with the spare
(which does not have monitoring) for a while, then when you replace
the orginal wheel with a new type there is no problem
