It sounds stupid, but stick your lips on the sensors, you should feel the ones that are working are pulsing, you can also just use your fingers, but the lips works better :), easy way to diagnose a non working sensor, it's another thing if it's just not reading the correct distant, then you need a scantool to see which sensor is bad.

Holy crap, that's genius. I'll try it tonight. I did already order more sensors, so the money is already spent, but I wanna see if this works.
