The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

well on my car these are reffering to the sensors in the exhaust, the upstream sensor(before the cat) and the downstream sensor(after the cat) the downstream sensor can act up if it is lazy or sluggish, or due to a bad catalytic converter or a clogged one. however there are sensors on the exhaust manifold which are determined by driver side or passenger,my opinion is to get a scanner for about $100 to $150 and you can figure out many of these codes yourself.

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

READING CODES USING MIL (CHECK ENGINE) LAMP
Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.
