I have a 2003 F250 with the 7.3 powerstroke. I had some stumbling and the CEL light came on. I ordered the OBDscan software and pulled codes and got p1280 p0000 p0000 during the KOEO test. During the KOER test it displays a p1284 P0000. I know they are related to the ICP sensor. I have checked continuity between the sensor connectors and the pcm plug and all three wires showed no break in continuity. I did a voltage check on the sensor connector on the harness from this link ECSD - Injection Control Pressure (ICP) Sensor - 1994-1997 Power Stroke FAQ and everything checked out is there anyway to check the sensor itself? Any help would be greatly appreciated!!!
