If anyone could help it would be greatly appreciated. I have a 1998 Mazda B2500 2WD. Ive been having trouble solving this problem P0340 Camshaft Position Sensor Circuit Malfunction. I changed the cam sensor just as a starter, because it was a cheap part, but it did not fix it. She starts to miss when accelerating and climbing hills. Not sure what the next step to do.

Thanks,
Sandman
