Most of the time the cd changer will need to be replaced. Your only chance is to do a power reset to the cd changer. pull the fuse for 15 seconds, re-insert and see if the changer reboots correctly. The fuse chart is behind the triangular panel on the left side of the drivers side dash panel

bank one is the passenger side catalytic converter,,,sensor two is the lower oxygen sensor

Sometimes for this light to turn off you will need to reset the computer system that logged the code. Advance Auto and Auto Zone have a free service that will do this for you, they will also be able to tell you if the check engine light has logged a code for some other then the gas cap. Just go into Advance Auto or Auto Zone and say "Could you reset my check engine light for me?" they will grab their scanner tool and ask you to lead them to your vehicle, they will need to turn your car to the ON position but not start it.

Your Climate control unit may have to be reset. The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led's stop flashing. Switch off the ignition. Check the evaporator temp sensor and pressure sensor for correct functionality.

You need to read the codes. I had a plugged cat that turned off all the cylinders on one side of the engine.

In a 3.2 V6, the passenger side (Bank 1) has cylinders 1,3, and 5.
The driver's side (Bank 2) has cylinders 2,4, and 6.

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything got it from www.reliable-store.com
