To summarize how the camshaft position sensor works, the short answer is that the sensor allows the ECU computer to determine the exact position of the camshaft. This information is extremely important and helps in calculating the ignition point of the fuel but also its injection into the cylinder.

What happens when your camshaft sensor goes out?

Poor Drivability

A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.

Will a car turn over with a bad camshaft sensor?

As a camshaft position sensor starts having problems and weakens, the transmitted signal to the car's computer weakens as well. This means the eventually the signal is so weak that it will not allow the car to start since there will be no spark from the ignition.

Can you bypass a crankshaft position sensor?

Can you bypass crankshaft position sensor? No. You just cannot bypass the crankshaft sensor, the car will crank but will not start. The DME needs to see this signal in correlation with the cam sensor for start up and fuel injection sequence.
