Author Topic: Who can modify the ecu on my `04 f150? P0011 P0021 Posi12Bolt New Member Member # 11846 posted                              Truck is a 2004 F150 5.4L, installed VCT lockouts due to loud cam phasers. It idles great, but now it throws P0011, and P0021 which is basically a problem with the VCT circuit on bank 1 & 2. I'd like have the computer ignore those from now on, is there anyone local that can make that happen?

I work on all makes and models from engine work to gears. Check engine light problems too. 916 912 3493 Posts: 1217 | From: sacramento | Registered: Mar 2008  |  :
