I'm new to using a scanner, and mine is pretty simple...still, I'd like to understand something I can't find anywhere.
On my screen, just after the "code," it usually prints a dollar sign followed by numbers - like $10. That one follows a P0430 code for sensor 1, bank 2.
Okay, I've learned that this "identifies the control module number from which the data is retrieved." But...what does that mean? Is there a site other than the o2 sensor that collected this data? Is it a clue as to the specific source of the problem?
Thanks for any assistance!
