Check the wiring and connections and if ok then replace the sensor. Check air gap to the rotor and check that there is no dirt or anything else that can affect the air gap

you bypassed the wires that connect to the sensors? that would have been my first guess the harness that plugs into the sensor. after that i would check the ground connection from the ecm. wouldn't hurt to check the battery posts too. if the battery posts are oxidized you can have all kinds of goofy electrical problems. hope that helps.

Have a compression test done while the engine is warm,It sounds like you have a valve sticking open sometimes or maybe even a burnt valve.

That makes the computor think the timing is off. Replace the sensor and see if that does it. You will then have to have the code cleared (erased) or the light will come back on/stay on.

SOURCE: Code: P0340 Cam shaft position
Check your PCM GROUND, And Also Disconnect and Inspect ALL ENGINE Harness Connectors, FORD Has Had Many Problems Over RECENT Rears With FAULSE CODES Due to Poor GROUNDS @ ENGING/BODY/COMPONENT/ GROUND Locations, And ALSO HARNESS CONNECTORS with Poor Connections, It May Not SEEM REAL , But I Have Ran into this COUNTLESS Times.
