Ducato Factory tyre pressure monitors

[peterc10]

We have these monitors fitted to our 2015 Hymer. Does anybody know how they work please? There does not seem any receiver or sender fitted to the wheel, so they seem not to work like the after market fitted monitors.

The reason I ask is that I will need a new set of tyres in a few months. In addition I want to get my Hymer alloys powder coated, because the alloy finish is shot. I could kill two birds with one stone if I can buy tyres on the internet and get the powder coaters to fit the new tyres. But before that I need to know if there is anything on the wheels that they will need to take off and put back so that the monitors still work.

Thanks for any help you can give.

Not sure on your particular vehicle,but all vehicles I have come across have a "sender" inside the wheel usually as part of the valve

 

[Driventemple]

I too have the Fiat tyre pressure sensors. They are incorporated in the valves and so I think you should ensure the wheels go back to the same position?

There is a sender unit inside each road wheel, as part of the valve.
The single receiver unit is on the engine subframe's crossmember, behind the engine.
You have been very lucky if all 4 of your sender units continue to function after 8-9 years and I wouldn't consider retaining these with your new tyres as they will surely begin to fail soon.
I would ask the tyre depot to fit new valves/senders; they will almost certainly have a range of programmable universal senders that they can configure for the Ducato. They may clone your existing sensor IDs although this isn't necessary as the vehicle will learn any new IDs as you drive.

P.S. the wheels can go back in any position and the vehicle will learn the positions automatically (using WAL - wireless auto-locate).

That's interesting. I intend replacing the tyres at next service because, although only 7 years old, I'm fed up with the 'bang crash' effect of CP tyres. Looks like it could get expensive with new special valves as well.

Have a look on eBay TPMS DUCATO for idea of price

Interesting question. On our cars I'm told the tyre pressure warning is driven by sensing differences in the number of rotations the wheels make it seems to sometimes work !

 

[peterc10]

Thanks everybody. My motorhome stood for a year on the forecourt before I bought it at a bargain price. So that means any batteries in the valve are over 9 years old and 46,000 miles. That is some good battery to last that long! And yes my tyre pressure light goes out when I switch the ignition on.

 

[oldiesontour]

TPMS are motion sensitive using power when moved in most of not all cases,but even so.
9 yrs is surprising.
Looking on eBay they seem to be £60 to £150,I would think tyre shops will insist on fitting new as there is a good mark up on them.

Fairly certain with the age of your van they weren't fitting them I think it was about 2019 and Hymer don't have them fitted anyway.
Also the Fiat ones are a pain as it is difficult if not impossible to change the pressures they are set to, even Fiat dealers don't know how to do it.

Mine is a 2017 Heavy and I changed the pressures on mine using Multicuscan.

Maybe it's the Peugots that it's difficult on.

Maybe it's the Peugots that it's difficult on.

And IVECO programmed with the chassis and the dealer says he can't alter (maybe can't be bothered), two sensors lasted just over 4 years

Definitely got it Lenny. My son managed to change the pressure settings through the OBD for me, so he knows more than the Fiat dealer. It was a factory fit option. One of the £20k worth of optional equipment that the person or dealer that specced the motorhome chose. Listed at £140. Just noticed from the option price list that the "optional spare wheel" is not equipped with tyre pressure monitoring sensor. That clearly suggests that there are sensors in the wheels.

They can insist as much as they like but I ain't paying for them if I don't want them.

Can I just ask if you have a sensor/sender like this? It's in the passenger footwell.

That looks like a TyrePal repeater to me, although the one I have just fitted is black.

It was already fitted to the van when I bought it but I have no idea what it is supposed to connect to - any ideas??

Do you have a screen displaying 4 separate wheels,also do you have big valve caps?
(I may be barking up the wrong tree here)

No display apart from a Snooper sat nav & these are the valve caps:

sorry about the state of the wheels!!

 

[oldiesontour]

Doesn't seem to have after market TPMSstill fitted,but maybe someone took valve caps and display away,not realising a repeater had been fitted ?

If this question is aimed at me the answer is no.

No batteries in the wheels

I expect the wheel referb co wlll have come across tyre pressure monitors before

 

[peterc10]

Where do they get the electricity to send information wirelessly?

 

[denisejoe]

Don’t know but they must be the best batteries in the world as I have never changed them in Denise’s car and that is 8 years old.
My car senses the difference rotations of each wheel is the best way of describing it.

The different wheel rotations like ours is an indirectly way of sensing tyre pressures. Ones that measure pressure directly are battery powered I think a lot of them have the ability to charge from the energy generated when the wheel rotates a bit like an automatic watch.

 

[oldiesontour]

Internal sensors do not have batteries,in very simple terms they are" powdered" by radiowaves.Not but think in terms of microwave ovens.
They tend to last around 5 to 10 yrs.
If the light is on on the dash it's an MOT fail even if the tyre is obviously correctly inflated!
External (big valve caps) are usually battery powered
