OBD-2 Automotive Code Encyclopedia and Cross-Reference Guide By Mandy Concepcion This guide was written without the sponsoring of any one particular company or organization. No endorsements are made or implied. Any reference to a company or organization is done purely for sake of information. Here, you'll also have access to a series of useful cross-reference automotive sensor values, such as MAP, TPS, FRP or fuel-rail-pressure sensor, etc, which makes for a useful tool during repairs. All codes seen in this guide were backward engineered from the development of our Scan-1 OBD-II Scanner and Diagnostic System. Due to our extensive development with automotive ECMs and the Scan-1 we were able to compile the most complete OBD-2 code list in the industry. Due to the nature of the development of the Scan-1 the definitions here may differ somewhat from other publications. In one word, the Scan-1 being a completescanner and diagnostic tool generated a large amount of information, which we're now able to bring to you in a cost effective way. In this publication, you'll also have access to all the Generic OBD 2 code definitions, as well as the code setting criteria. Keep in mind that although the OBD-2 code definition is the same for all manufacturers; this isn't so for the code setting criteria. An effort has been made to keep the data as simple and straightforward as possible. In certain cases, the manufacturer has specified multiple instances of the same code. When presented with this situation, simply study the multiple instances and apply them to the vehicle at hand.
