So I live in a really hot area. I parked my car in a cool cement garage and came back to a car that would not start up and hour later. WHen i finally got it to turn over, I did so by pressing the gas(I have an auto). As a result the car started at high rpms. WHen my car started up, the CEL was on. I took it to get scanned and it turned out to be PO340(camshaft position sensor), sensor A, bank 1.
1. Can this effect the starting of the engine?
2. If so, why does it say sensor A, bank 1 when there is only 1 camshaft pos. sensor?
3. Could the reason my CEL came on and said PO340 be from pressing the gas and it starting at a high rpms.

I still have trouble starting it every once in a while.
