What is the scale of the code-o-meter?

Question

For instance, What does 2/100 mean?

Answer 1

It means how common the code is with the Engine-Codes.com visitors.

For example the most viewed code is the P0455 Ford code, which is almost 100/100.

Since Engine-Codes.com is one of the visited web site on the web for engine codes information, and the code P0455 Ford is the most visit code on Engine-Codes.com, then the P0455 is a very common problem code on Ford vehicles.

If a code is 2/100, the code is not as common as the P0455 Ford. For every 100 visitors searching for information on the code P0455, only 2 are searching information on that code.
