How to Read through a Verify Engine Light on a Honda Accord

While most cars launched an onboard diagnostic method on their cars as an "OBD I" method, Honda introduced "OBD 0" as their first diagnostic strategy. Individuals who are not familiar with Honda's computer systems may confuse this with the much more common "OBD I" method. When your Honda is experiencing problems, it's important to know which kind of diagnostic procedure your Honda Accord uses. Accords from the early 1990s, for example, used an "OBD 0" procedure, whereas newer model Accords employed either an "OBD I" or "OBD II" system. This diagnostic process will determine what diagnostic scan tool you'll need, but the actual process for reading the check-engine light will be the same regardless of the computer.
