Question mazda 2 warning light/mpg reading

I have a 2014 Mazda 2 venture sport. When driving the mpg reading displays erratically and there is a constant light on indicating that a tyre is low on pressure when it is not. Any ideas what is wrong and how to fix this?

Have you reset the TPM system?

With the MPG reading, are you reading the long term average display, or the real time usage display?

Set all your tyres to 34 or 36psi - cold. Turn ignition on, press and hold TPM button until it beeps and flashes icon on cluster. Real time mpg is just that, if you accelerate mpg will drop, if you ease off mpg will go up, its real tome live data from the engines computer.
