Hi! Welcome to JustAnswer. Thanks for coming! I'm Ron Z and I'll be helping you with your question today.

On the 5.4L engine setup, there are 3 oxygen sensors. One sensor mounted to the exhaust just below the exhaust manifolds, and one mounted behind the converter. Do you happen to have a p-code for an oxygen sensor? If so, I can better tell you which one you're looking for.
