Rats! The CE Light came back on yesterday evening. Using the code reader, the codes resulted in the following:

DM:
22: Crankshaft position sensor signal faulty
25: Knock sensors or engine control module faulty

Pin8:
25: CMP sensor not recognized or implausible
33: Maximum retard setting on at least one cylinder has been reached or the ignition angle deviation between the individual cylinders is greater than 6 degrees crankshaft angle

Pin14:
1: No fault found

At this point, I'm assuming that I should replace the CMP sensor. Is this correct? If the CE light comes back on, then the CPS sensor or should I just replace both? What do you guys think? Is it safe to drive the car around until the components are changed?
