P0198 Can't Clear

Working on some issues on an 03 6.0 F250. One thing that has us a little stumped is the P0198 code. First we checked the plug looking for the free fix with no change. We had to replace the ICP sensor so we changed out the oil temp sensor at the same time. Well....the P0198 was still there. Clear it and it comes right back. Well...must be a problem with the wiring. We tested from the sensor pins to ground and back to pin 44 on the pcm plug and all ohms out just fine. So now we are stumped... new sensor and checked the wiring for shorts/opens. Any ideas?
