Hi Guys,
Just wanted to report back in. I had a mechanic I trust check out the P0480 error code (see original post). He went through the suggested procedure for debugging the error code and could not find any problems. He also could not reproduce the ignition switch problem (radio not comming on) so did not want to replace the switch.
The problem I'm having now is that the P0480 code keeps comming up. My car fails inspection because they will not pass it with the check engine light on and resetting it resets the emissions. By the time the emissions codes are ready the check engine light is back on! I'm afraid if I take the car to the dealer all they will be able to do is start swapping components until the problem goes away and that could get expensive!
I think it makes sense to replace the ignition switch as it appears something is wrong there, but if that does not fix the P0480 code I'm not sure where to start. I really don't want to have to start randomly changing components, but that may be the only way to fix this since the system appears to be fine.
Any thoughts?
Bill
