how to disconnect the tyre pressure sensors??

[nicke999]

happy new year to one and all.....

I dont know about you but I'm pretty fed up driving around with the warning signal on the dash, and then it seems just vanish - this system in all the Aston's i have had never seemed that robust.

conclusion - switch it off

how do I do this, is there a fuse to tug at???

thanks Nick

What's the warning signal Nick ??

Do your tyres just need a bit of air ??

What impact on insurance / warranty if involved in a tyre-related incident ??

I genuinely don't know

some of the early cars didnt have tps, or you had to order as an option, so it would not affect anything..

the warning is saying what it should say, but all new tyres and all pressure correct. but this is not the first time, and not just on this car - its a common issue

[Jockman]

Has anything happened to the tyres or their surroundings recently which may require the sensors to be reset ??

Otherwise, your Manual will have the Fuse references near the back - not really recommended unless you know what you're doing

Worth checking the tyre pressures anyway as the system is usually pretty good - also worth scrambling around in the passenger footwell (if you have the earlier set-up) to see which tyre is causing the problem, so you can carefully check for a nail. Once you have done that, if it still comes on - time to visit your friendly dealer.
Best of luck.

I noticed the tyre pressure warning light coming on not long after I bought the car. The dealer in Edinburgh told me to wait until the "Power, Beauty, Soul" message had finished *before* pressing the starter button. Something to do with a self-check that includes the tyre pressure sensors. Worked for me...

Good advice from Grant & Oceantools

My last one used to do this, apparently the original system fitted to 4.3's and early 4.7's struggles to keep in contact with the sensors on the rear wheels. So it throws a wobbler sporadically.
I was advised the power cable to the TPMS box on this version could be pulled to turn it off, but only this version not the updated version on later 4.7's.
The new system on the S is a lot better and the little display in the dash with actual pressures is nice. Amazing how much they increase once the tyres warm up!

Does it really use pressure sensors in the wheels...? How does that work...? How are they powered...?

Every car I have had with TPS used the ABS wheel speed sensors to monitor tyre pressures. Seems bizarre to me that anyone would do it any other way...

On our very sedate drive from Brooklands to Hindhead, I had a "Tyre System Failure" message on the screen. After a couple of miles, it went out. It was also accompanied by a yellow flashing light from the passenger footwell.

Anyone else had this?

Surprised you were going fast enough for the system to realise the car was moving!

It does!

I think tpm is now included in a MOT test,so of it's fitted it must work or your car will fail.

ABS sensor based tyre monitoring doesn't actually measure pressure, but calculates the circumference of a tyre based on rotation. It means that in theory if all your tyres were underinflated it wouldn't highlight it as they would still read the same relative to one another.

A proper pressure sensor based system should be far more accurate and quick to react than an ABS system.

ABS systems are cheap though...

JohnG1, to be fair, I was behind Yeti so you may have a fair point.
