Howdy Folks,

First time poster here

I am reading my check-engine codes and I am getting (1) flash of code 12 then we get 5 consistent flashes - pause - then 3 flashes (the pause is pretty significant) and it does this (3) times. Then we get 6 consistent flashes - pause - 3 flashes and cycles (3) times.

These (2) codes seem to be 53 and 63 right..? Well everywhere I have read says code 12 will flash (3) times, not in my case.. Also everyone has said it will revert back to code 12 when completing the code reading cycles, not in my case -- the 53 and 63 codes keep repeating and repeating and repeating...

Any input would be awesome!
