Computer problem
2001 Nissan Sentra Two Wheel Drive Automatic 93123 miles

I recently got " Service Engine Light" and after diagnosis I got " Coolant Temperature Sensor" replaced. The light went off but mechanic suggested that he is getting some random error codes and so there might be problem with ECU/PCM.

What is the difference between ECU and PCM and what needs to be replaced?
I have 2001 Nissan Sentra GXE Automatic.

Also, please suggest the right person in Denver who can help me with this repair.

What will be the approximate cost?
