tire pressure sign on mhy car

For the past 5 months my car has a tire pressure sign on, when i take my car to HONDA midrand they remove it. <br> they remove it for a minute as soon as I drive off it appears again.<br> I have been there so many times, in winter i was told most of their cars does that in June but now it October. I have been there for more than 10 times.<br> <br> this problem is not resolved. A week ago i took my car for a service if remember well it was last week Wednesday. sunday same signage came back. <br>
