Can I still drive with a bad camshaft position sensor?

If the cam sensor is the only input the ECM uses to fire the spark plugs or fuel injectors; then NO, it won’t run. If the engine starts and runs reasonably well; then you can drive it. You will use more fuel, be emitting more emissions, and you may damage the catalytic convertor.
