this job is no picnic! a special socket is needed and depending on which sensor, maybe a box of band-aids. unless you can replace easy stuff like brakes,oil,etc i'd keep paying for replacement of sensor as the prefered option. no offense intended.

A slotted socket is about $15-20. There are 2 x 2 (paired) sensors - (4). You will need to have good access under the car to get the torque needed to remove a couple of them (Plus an extension).
