I have checked all the fuses, all are still good! both inside the car and in the engine bay.
I also tried to read my brother 2003 Neon, of course it didn't have the CEL, but it read and pass all test.
I'm starting to have the feeling I have to replace the computer inside the car??
I will try the wiggle technique.
As for corrision build-up, you mean for the scanner or the car port??
And if there is corrision...how am i'm susposed to clean it if its a female plug??
Thanks,
Jim
