jesus,turn off the caps,and learn how to write a sentence!
there is a simple troubleshooting procedure in a $10 shop manual from an auto parts store.there should be 5v on one wire,ground on one and a signal back to the ECU on one.the signal voltage varies with vacuum,up to 5v.if there's only 5v on the feed wire,and more than 5v on the signal,the sensor is bad.if there's more than 5v on the feed wire,you're either picking up voltage from a short to a 12v wire,or the ECU is sending too much current(doubt it since all the 5v sensors get their feed from the same circuit).
