I'd inspect and clean the EBP sensor connector first, then under the Dash.. pull fuse # 15.. (or disconnect the Batts) for 20 minutes to erace the code (from the KAM) from the PCM.

Scan it again.. see what you git ?

check the sensor tube going from the sensor to the front of the pass manifold. They have been know to rot to pieces.
