Hi I wish to know if the tyre pressure indicator show which tyre is low or just that a tyre needs to be inflated. Mine is showing a low tyre indicator in the dashboard. I looked around my car and all of them seems to be good.

Hi friends I managed to sort it out the issue with the low tyre indicator, I found that one tyre was slightly low and after inflate it the tyre warning light went off without doing nothing. I left the engine running while checking the tyres and I didn't had to go to setting in the menu to switch off the warning light as I read in other post. It was really few below the right pressure and it's my first car with such warning light.

Re tyre pressure monitor. There are no sensors on the tyres on the B Max, it uses the ABS system to monitor the rolling citcumference of the tyre, when a tyre loses pressure it in effect becomes smaller thus rotating more than the other tyres and inducing a tyre pressure warning on the dash board.

Thanks, I had the impression that a sensor is attached inside the tyre, It's really useful to have.

There certainly are sensors on my car - which is the pain in the a** because one set of sensors cost roghly the same as set of winter tires.

I would very much prefer ABS monitoring system, but no such luck.

This information is NOT correct for my 64 plate B max Titanium X auto.
Having had the warning twice, I checked pressures and found one to be low. Pumped up and warning went off again.
Had it checked and had a faulty valve. The tyre fitter told me that it was an ABS based system, as above, but then when he took the tyre off, he discovered that it was a pressure sensor valve stem, which connects somehow (Fitter said Radar??) to management system.
New pressure sensor valve fitted and sorted.
Only problem, standard valve £5 + VAT, pressure sensor valve, £25 + VAT.

I can alao confirm that each wheel has a pressure srnsor built into the valve.

Hi, New to this site. Have a 14 plate Titanium X manual which has had an on going issue with warning light on dash coming on for low tyre pressure. Have been inflating tyres on a regular basis and now my husband has replaced the inner valves on rear but, although time space slightly better, still have a problem. Tried taking it to STS Tyres and they said it was a very common problem and Ford only part so they couldn't help. Surely if this iscommon shouldn't Ford recall it? Also, read somewhere that because someone had a corrosion problem with faulty sensorit meant replacing the whole wheel!! No doubt Main Dealer is gonna charge a small fortune for a 15 min job?!

have you reset the monitoring system after setting the tyres to the correct pressure?

under vehicle settings, select tyre pressure, and hold ok until you get a confirmation message.


you can find the information in the fiesta handbook, for cars after 7 april 2014

Hi Maxine, just carried out the tyre presure resetting procedure yesterday following a rear tyre replacement caused by a wood screw in the shoulder which rendered a repair illegal. As stated, the resetting is very simple if you go into vehicle settings and follow the instructions. Let us all know how you get on.

We have ongoing issue with tyre valves. Ours have the sensor attached to the valve stem inside the wheel.
The back tyres started going down regularly, not faulty sensors they actually were going down with leak proven to be around the base of the valves.

We ended up buying a set of four new valves from Ford and our tyre dealer fitted two to the back wheels. One continued to go down and we went back and he fitted another. This continued to go down and we can see nothing wrong with the wheel rim. We found that if a pool of water is poured in the rim around the valve and slight pressure applied sideways to the valve air can be seen to escape. We tried sealing with silicone and fitting new valves again as they easily damage on removal each time.
In France recently both were going down again and in the end ruined a good tyre due to running flat unexpectedly. I temporarily fitted a normal valve (and have had to live with the system telling me that the sensor is missing). Now back in uk I am about to go to Fords to try an get these issues sorted.

How big an issue is this? Does anyone have any solutions please?

Following from above, the normal valve works just fine! The other continues to go down as do the front from time to time.

Still haven't sorted this. Keep using Mums Yeti! Dealer said to replace complete valve is c.£85 + vat and to inspect it first to diagnose would be £80+ vat. Husband said it seems to be leaking around the base and he thinks it gets to a certain level and stops. I'm not keen on risking it going down. He also thinks there is a slight corrosion problem so chances are dealer will say I need new wheel/s. Just want rid of car now shame cos I actually liked it once! Still dithering about what to do.

Shame to ditch a car for such a small reason Maxine. what I would do would be to switch the system off in the menu and just stick some ordinary valves in.

That's what I would do as well. Luckily I don't have them on mine.

I am very tempted to fit ordinary valves and get the system switched off.

Ford Dealer today was totally uninterested and wanted to charge £108 to diagnose the problem i know I have!

Just before my 3 yr warranty expired, I had one leaking valve stem. Ford said, normal wear and tear.Then, over the next three months, the other three all leaked.
I replaced them all with non ford parts at a local tyre centre, £30 each for fitting and balancing.
Apparently, the Ford valve stems are prone to corrosion, which creates small capillary leaks.
The fitter suspected that they were several years old and that Ford had been using up a huge backlog of old stock.

It is odd that the Ford main dealer say they have never had a problem but any used car dealer says they get the problem all the time.
