P-1280
Hi all needing some help for a friend. I normally hang out in the 6.0 section so bare with me. I attached a code down load from AE and as you can see he has a active P-1280 code. So far the sensor and pig tail has been replaced. I will watch the ICP Pid and the voltage will be ok the drop down to 0 then come back. I looking for some suggestions on what to check??

Is the check engine light on as well? Also, did you clear the trouble codes after replacing the sensor?
Strange that the MAP reading is 25 with the Key On Engine Off. It should be reading the same as the Baro and EBP sensors at KOEO.......
Since you have AE, I would data log a 20-30 second WOT run from 50-80 mph. Data log, ICP, ICP duty cycle, MPH, Baro pressure, MAP, EBP, Fuel Inj Pulse Width and RPM's. Then post up a pic of the graph so we can see a snapshot of the run.
