Advanced Diagnostics Explaining Your P codes and U codes

 

Diagnostic trouble codes (or fault codes) are codes that are stored by the on-board computer diagnostic system. These are stored in response to a problem found in the car by the system. These codes are stored when a sensor in the car reports a reading that is outside the normal/accepted range (Eg: fuel mixture too rich) the most common codes you will find are P codes and U codes.

These DTC’s identify a problem area which is intended to provide the technician with a guide as to where a fault might be occurring within the vehicle.

Generic
(normally P0xxx) The definition for the code is defined in the EOBD / OBD-II standard and will be the same for all manufacturers.

Manufacturer-specific
(normally P1xxx) Where manufacturers feel that a code is not available within the generic list, they can add their own codes. The definitions for these are set by the manufacturer.
