heres the deal for the past three months i have been dealing with my CEL light coming on and off, dealer is at wits end but we do have some good info, i think anyways, heres the deal my fuel pressue sensor voltage is telling the computer it wants anways between 70-90 volts, well normal voltage is 1.5-3.5 tops, we took a fuel pressure sensor off a BRAND new truck and the light still came on, meaning that the sensor is not bad, we also put on a new fuel control accuator to see if that had any issues with this, well that didnt change a thing.
My question is what would the cause be? any ideas at all?? here is what we are afraid of i did the bully dog try before you buy thing back in july, it wasnt in there more than maybe 6 hours, then after i did that i had them do the reflash for better fuel economy thing. If dealer calls star and reads these numbers etc, is star going to say, warrenty void because customer had a downloader in it?? or would the tri-b4 u buy thing totally have erased its self?? any help please???


code is P0148

 

fill out your Sig. we need to know what year the truck is.... it sounds like it is brand new????? 06-07???

 

I posted in your HELP! section thread instead.

Have the dealer try to reprogram the ECM again. Wonder if a portion of the download was somehow corrupted during the transfer.
Also check the ECM connector for corrosion.
