How do i reset the tire pressure senseor i have a 2008 volvo s80 3.2

then go see a tire shop .

If the tire is at the correct pressure, then the sensor has gone bad and will need to be rebuilt or replaced.

I would manually check tire pressure to see where you are really at on all 4 tires. Then reset the light again. There are some issues with the base module, not just the sensors. In addition, you could have a failing battery in one of the sensors, or a bad connection. You would need someone with the VIDA system to reset and get the system to "re-learn" what it is supposed to sense.

Have the dealer scan the system for a poss defective pressure sensor inside the tire.

drain all air and reinflate tires

Reset all tires to the correct pressure and drive the car. It should reset within a couple of miles.

Yed the RFID sensors will send the proper signal to the computer and they will reset. Be sure your tire pressure gauge is accurate. Mine was out by 5 lbs and I struggled with that problem for a couple of days. went to a tire store and compared readings. threw gauge in garbage

get to the t.p.m. menu and hold down scroll button until it clears

Hi there,
Front tyres: 2.1 bar/30 psi
Rear tyres: 1.9 bar/27 psi

Cheers.

i'm not sure exactly what the question is but there is not tires with sensors sensors are always mounted on the rims by the valves but if you install a diferent wheel then the light monitoring the air pressure will come on
