The Camshaft Position Sensor (CMP) provides the PCM (Powertrain Control Module) with a voltage signal indicating the position of the camshaft. This information also determines if the signal from the CKP (Crankshaft Position Sensor) is correct. Altogether it is used for fuel injection timing and ignition timing.
DTC P0349 OBDII indicates that the CMP sensor input signal is intermittent. This is due to electrical circuit faults. This code is set for engine bank number 2.
