tyre pressure sensors

Oct 29, 2007 7 Replies

Hi Everyone



I've got a 407 with pressure sensors on the tyres. I had a tyre replaced recently at a tyre dealer , and now the dashboard display comes up after a few minutes running saying 'the tyre pressure(s) are not monitored. '



Talking to a parts dept they tell me the new sensor is £56 + vat to buy and I presume there will be a fitting charge. So I'm looking at a £100 bill I expect.



Anyone else had experience of this? Any advice?


Simple question, is the sensor plugged in? Presumably there is a wire running to the axle and then some sort of capacative or inductive coupling to the sensor in the wheel [1]. So did thetyre fitter inadvertantly disconnect the wire. It would only take a few minutes to pop the wheel off and check.

[1] The only tyre sensor I have any knowledge of is on the Airbus A330 and that was in 1989

The sensor was ripped off by an incompetent tyre fitter when they changed the tyre.

You have four choices:

1/ Ignore the warning. 2/ Have the dealer reprogram the car so the warning isn't given. 3/ Get the tyre fitters company to pay for a new sensor to be fitted. 4/ Pay for it yourself.

As I bought my Citroen (same system as Peugeot I believe) second hand with tyre sensors ripped off by an incompetent tyre fitter I opted for

2.

It's a little plastic black box about the size of a swan vestas match box inside the tyre connected to the valve.

Presume it's a little wireless transmitter.

When the tyre was fitted the company did warn that it was possible the sensor would be damaged so I can't argue with them. As they had`fitted 2 tyres ok a month before I thought they would do the same..

Just spoken to a Peugeot dealer

Diagnostic fee then parts purchase and fitting and reprogramming fee. About £180 - £200 they reckon. More than the tyre cost!

Methinks I'll ignore the messages for a while.

Intriguing, I'll give it a whirl.

I wouldn't put it past a dealer to charge £80 to diagnose you need a reboot and then £50 to reprogram by disconnecting and rebooting it!

Ok, that's interesting. I wonder where it gets its power from?
