Check engine light code p0340
Okay so i had the camshaft sensors replaced by aamco but about after....40 to 50ish miles it came back on. I tested the alternator (through the battery) and at off it was 12.7ish volts. I started it up and kept off everything (lights, a/c, radio) it was 13.7ish volts. With lights on I got 13.6ish and with a/c I got 13.5ish. Now with the radio on i got 13.9ish volts or so. Im just super confused by whats going on. To my knowledge those are good results i think. Do you guys have any advice/tips?

If the wires to the sensor are good the next step is your PCM (power control module) should be checked out. From what I've read …..They are several youtube videos on this code but I didn't watch any of them...
