It's best to use Mopar OEM sensors. The PCM supplies the sensors with the 5V supply. The sensors then send their signals back to the PCM. Aftermarket sensors don't always stay within the signal range the PCM is expecting. If it's not the sensors it could be the wiring harness/connectors. Check the condition of these. Also check the condition of all the engine ground wires. There's a tone wheel behind the crankshaft & camshaft position sensors. If you do replace them, check the tone wheel for damage, foreign material, or excessive movement.
P0300 could be getting posted because of P0335. If P0300 is getting posted for other reasons the problem could be the items listed by FlyersHockey.
