The mechanic told me that there were too many codes coming out of the pcm for him to give them to me. They also told me I need to replace oxygen sensor Bank 2 sensor 1.

Thank you.

Your best bet is to take the car to a parts store (autozone or advaned) ask for an OBDII scan and have them reset the light. The scan will give you all the code and it's free. Replace O2 sensor Bank2 Sensor 1 (Passanger side front o2 sensor) then wait for the check engine light to come back. Once the light comes back go and have the OBDII scan do and find out what the codes are.

If the PCM needs replacing (per my original question) are they going to get valid codes and if the PCM needs replacing, shouldn't my car not start!

Just because there are a lot of codes does not mean the PCM needs to be replaced. Also the car may still start, but you may get false codes.
