407 Tyre Pressure Monitoring System

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

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

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?

Pete

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?

Grtz, Eric B.

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.

Pete

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
