Code P0340 Volkswagen Description
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Bought a 99 vw beetle and tried to drive it home. The connector to the radiatir hose blew and the car started to overheat. The engine stalled and was able to jump it back. Drove it intermediatelly to try and get it home, probably a mistake, however it died again and wouldnt start. Towed it home, put an odb2 reader on it and it gave a camshaft sensor code. Replaced camshaft, making sure to get timing correct, replaced crankshaft sensor as well. Car still wont start and camshaft sensor code is still there. At a total loss..... Ideas?
