The following OBD II error codes are the most commonly found with this product type. On-Board Diagnostic (OBD) systems are integrated into the computers of our vehicles to monitor emissions. The first generation of OBD requirements was implemented in California in 1988. Since then, these requirements were adopted by the US EPA for all passenger vehicles manufactured after 1996. In 2005, OBD systems then also became mandatory for heavy-duty vehicles and engines up to 14,000 lbs. GVWR. In 2008 the EPA finalized OBD regulations for 2010 and later heavy-duty engines used in highway vehicles over 14,000 lbs. GVWR and made changes to the OBD requirements for heavy-duty applications up to 14,000 lbs. GVWR to align them with requirements for applications over 14,000 lbs. GVWR.

OBD II is now the standard in diagnosing vehicle emissions in. The codes listed for this product type are common instances that may relate to your vehicle and should be used as a guide only. Walker Products will not be held responsible for any use of this information. It is highly suggested that you consult with a professionally trained mechanic prior to any automotive repair, and that you follow all vehicle manufacturer and EPA guidelines for removal, replacement, diagnostics, OBD II code clearing, ECU and PCM relearn procedures.
