For some reason all 3 pins on the plug are getting 12v ground. Nothing seems to be touching or grounding out anywhere. Has anyone else ever had this issue? Hondata is showing 4psi of boost at idle and dumping fuel.

 

If you miswired the sensor at any time then the sensor is damaged and will have to be replaced.

 

Are you seeing a short to ground on every pin of the connector when its plugged into the sensor or when the connector is unplugged but the Key is ON, engine off?

Are you doing a continuity test or trying to measure voltage on each of these pins? make sure the spot you are putting your ground probe is actually a GOOD ground.
