puepuse of having tyre pressur sensor what does it do wid abs
It does not work in conjunction with ABS. It's purpose is to prevent blowouts- the running of a tire at a high rate of speed with low air pressure.
The tire pressure monitor/sensor is designed to alert the driver that one or more wheels is below the recommended psi. So check your tires, and if necessary, pump it up to the recommended pressure. (located either in your owners manual, b-pillar, or gas flap.) The pressure monitor/sensor doesn't work in conjunction with the ABS.
