[RESOLVED] installed GM3bar vacuum reads 21.7 all the time

[ApexVIII]

i posted this on dsmlink forums also but there is more people on here so maybe some one here might know

i ordered a 3 bar off ebay with a pig tail, the sensor was like $59 or something, i dont think its a actuall GM one because there is no part number on it,

but i installed it and i selected the GM3bar for the baro sensor, and it reads 21.7 vacuum no matter what the car off, or when i rev the car. even when the sensor is not pluged in.
here is a little log of when the car is off,

any ideas? bad sensor?

Thanks

Two things come to mind:

1. Wired it up wrong and damaged the sensor.
2. Just a bad sensor.
