Timing codes
I have a 2010 F-150 5.4L Lariat. I just replaced the fuel pump and relay. I also did an oil change. Now I have a P0012 and P0022 code. Can anyone tell me what the most common causes for this are with this motor? I just need a rough idea and some instruction on how to check some things to determine the issue.
