2004 SAAB 9-5 Engine Ignition Code / Camshaft Position Sens

Computer problem
2004 Saab 9-5 4 cyl Front Wheel Drive Automatic 55K miles

My Check Engine Light illuminated on my 2004 SAAB 9-5 Aero. I reset the computer and the light extinguished. The light remained out after a couple of restarts but on the third restart the light was illuminated. The computer was accessed and there were three codes present. P1334 Ignition System Fault, P1312 Ignition System Fault and P0340 Camshaft Position Sensor A Fault, in this order. Would this indicate that the Camshaft Position Sensor A requires replacement?
