SOURCE: check engine light
that code is saying that your catilitic converter is junk, but could be caused by some other problem also gas leak on exhaust system a/f sensor bank 1,2 sensor 2. heated oxygen sensor bank1 sensor 2, or the three way catilitic converter. these are the listed reasons for that code being thrown, to tell you the truth its not really that big of a deal ya know, i mean its just emissions, either the cat is bad or the oxygen sensor is bad in my opinion will it hurt the car? no, will that little light annoy the **** out of you? YES ; ) because the sensor is behind the cat it will not have any imput into your computer to change fuel maps or anything, the post sensors are only for reading if the cat is good or not, i actually cut mine off and the cat, the check engine light might always be on, but if my car messes up for some other reason then i will feel or smell it and dont really need the dummy light yea know? anyways its your choice to live with it or to take it to the shop and have your sensor tested/cat looked at, either way it wont hurt your car, if your front o2's start going bad you have to change those, but not the post cat one. dont let those shop guys bully ya into spending to much tell me what they say cause there always after an unsuspecting person's wallet, thats why i opened my own shop.
if this helped throw some blue/fix ya rating.
take care have a good day

I would think it would be just the Camshaft Position Sensor.I looked up the codes and they say pretty much the samething.
P0340 Ford Camshaft Position Sensor Circuit Malfunction
P1336 Ford Crankshaft/Camshaft Sensor Range/Performance

Check your fuel cap to see if it is on good.This all deals with that,you may even have to replace the fuel cap.But the emissions can mean a lot of thingsHave the egr position sensor checked and it`s hoses,Check the air filter and have the egr took off and cleaned and checkedI hope this was somewhat helpful,emissons can be trickie.
