If the alternator is producing AC waveforms (the regulator has broken-down and not rectifying AC supply from the alternator - you'll have weird stuffs going on.
You may loose your car ECU, body controller and everything else.
There isn't a camshaft position sensor. If you are asking because of an error code you received, it is caused by a signal that mimics the same signal as a camshaft position sensor.
bad camshaft position sensor
spelling error - sensor - detects camshaft position for engine controller
Intake Throttle Position Sensor High Voltage
Camshaft position sensor circuit malfunction.
Replace the Accelerator Position Sensor. Located on the firewall.
P0406 - EGR Position Sensor High
Egr position sensor rationality. Likely a failed egr valve.
Trouble code P0340 means:Camshaft position sensor circuit malfunction
Yes it very well could, because a misfiring coil pack or weak coil pack can cause interruptions in the signals to both the camshaft position sensor into the crankshaft position sensor. I had this happen on my Buick LeSabre, it gave a code 18, which is Cam / crank position sensor error okay. I replaced all three coil packs, and it went away and never came back. If you look at the diagram for the wiring of your ignition control module, you'll see that the coil packs, ignition control module, and camshaft and crankshaft position sensors are all interconnected.
Trouble code P0820 means:Gear lever X-Y position sensor circuit
Throttle position (TP) sensor circuit, very low signal voltage.
