What do I do? Simply change sensor again?

Question

I changed the Camshaft Sensor and it worked fine until a few days later it all of sudden quit. The car completely stalled, lost power, and got stranded. The code I got was P0340.

Answer 1

P0340 is not going to cause the engine to stall out it will cause it to not run right, what power the relay is the ECM rely these had a recall at one time, Try this replace the ECM relay if it never was replaced. P0340 does not cause a complete stall, lost power , it create a rough acceleration.
