sets below the intake manifold and takes about 5 hours to replace even if you are handy with cars it is a big job to take on.after doing over 50 or more for an old recall it still takes me about 2 hours to complete.

Both codes indicated a failure in the outputs of your air fuel ratio sensors. Because of the fact that both sensors are reporting incorrectly, I would suggest checking your AF relay underhood for failure, or your ground wire on the back of the intake manifold for connection.
Often when these cars have spark plugs changed or valve cover gaskets changed, the ground wire on the back of the intake (which must be removed to perform the mentioned jobs) gets left dangling. With this ground wire not attached, both A/F sensors will report 0voltage, resulting in the two codes you received.

Check for a loose gas cap first. This light set comes on for several reasons , generally caused by an air to fuel mixture problem, it can be sensing a defective O2 sensor in one of several locations, engine or exhaust area.
If the light does not go out a readout meter will offer more advice and reset options
