My Dad has readers that spit out codes in HEX and Decimal but it seems most other places they are listed as a P Code? For example misfire on cylinder 3 is 412F or 16687 -- most places online list P0303. The phone apps don't list HEX or Decimal either I don't think. I'm the one who always has to look these things up, it takes a while and it's a hassle. Is there a website or table or something I can convert these HEX or Decimal codes to P Codes more easily?
