Focus losing tyre pressure

Recommended Posts

Hi guys. My brother has a 2015 focus. Been tortured with tyres going down all the time. He's had tyres sealed, new tyres but still has to pump tyres every 2 weeks. Ford replaced the valves...but after 2 months its happening again. Question is my girlfriend is buying a 2017 model focus, it too has the tyre pressure system. Is the problem fixed in this model? Can you replace the valves with ordinary valves and put out the light on the dash with a computer? Thanks in advance

Afaik TPMS is a legal requirement on cars of that age so removing the sensors would be illegal and probably an MOT fail.

I've seen plenty of alloys that crack on the inner barrel.  If tyres are sealed properly and valves are good a hairline crack can be another cause for regular pressure drop.  As Pete said 'corrosion' plus sudden impact/shock via a nasty pot hole can easily cause a crack, happens more frequently with low profile tyres.  Sometimes these hairline cracks can be almost invisible, you really have to look hard sometimes.

I was under the impression it could be dedicated sensors or done through the ABS system just like deflation detection on my old Focus 😁 My current 2016 car has TPMS through the ABS sensors - normal valves.
