britton5 Posted August 27, 2020 Share Posted August 27, 2020 So my partner has a 14 plate fiesta. Her tyre pressure light came up on the dashboard, so I put air in them and it stayed on. I then reset the tyre sensor and it has vanished now. So providing there isn't a puncture, is this all good and OK? Thanks Quote Link to comment Share on other sites More sharing options...
The Finance Guy Posted August 27, 2020 Share Posted August 27, 2020 Did you put the right amount of air in to the correct pressure? If the TPMS light comes back on again then you’ve got a problem. Otherwise you’re fine. Quote Link to comment Share on other sites More sharing options...
britton5 Posted August 27, 2020 Author Share Posted August 27, 2020 The front I put bang on, and the rear I went to 29 I think which I know is slightly over. But originally, the dash came up saying check tyre pressure and they was all low 20s psi. But I did go for a drive after I reset it for about 10 minutes and it didn't come back on Quote Link to comment Share on other sites More sharing options...

That’s the one that’s leaking. Quote Link to comment Share on other sites More sharing options...

But if it's a puncture, then so be it. I was just checking it was OK to do the reset etc and have no repurcussions from it. 1 Quote Link to comment Share on other sites More sharing options...

The TPMS came on in my ST last night too. Weird. I wonder if maybe the sudden change in temperature has affected the pressures. Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted August 28, 2020 Share Posted August 28, 2020 Air temp and pressure does affect it for sure.On my previous car the warning came on as the car was parked in a very cold area but on driving it for 5 minutes the tyres warmed up and the warning went off.Sent from my SM-G965F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Comares2001 Posted August 28, 2020 Share Posted August 28, 2020 Tyres generally have to be around 25% below set pressure before TPMS triggers an alert. Trouble is with low profile tyres they can be that low without being visually obvious. All underlines why you should still check tyres regularly with your own gauge. 1 Quote Link to comment Share on other sites More sharing options...
