Description of the standard trouble OBD codes by family

Standard or generic fault codes are a list of codes common to all manufacturers.
This list of faults, also called DTC (for Data Trouble Code) has been defined so that any diagnostic device can read and decode them. They have a standard format as shown below:

The first letter indicates the family of DTC.

• P: Powertrain, (i.e. engine and gearbox)
• C: Chassis
• B: Body
• U: User network

The first digit indicates if the code is generic or not (green digit):

• 0: Generic fault
• 1: Manufacturer fault

As the list of generic OBD codes is not always sufficient, manufacturers can add as many of their own codes as they need.

The last 3 digits correspond to an incremented number (purple digits).
This may be a hexadecimal number (i.e. from 0 to 9 + from A to F). For P family codes, sub-families have been defined using the 1st digit (in this example the "3"):

• 0 , 1 and 2: for the air/fuel mixture
• 3 : for the ignition system
• 4 : for checking auxiliary emissions
• 5 : for engine idling
• 6 : for the onboard computer and ancillary outputs
• 7, 8 and 9: for the transmission (gearbox)
• A, B and C : for hybrid propulsion

These OBD codes were standardized using SAE J2012 and ISO 15031-6 standards which, to our knowledge, contain about 11 000 definitions in the most recent version.

Below you will find a list of the most commonly used codes. Our software contains all of the 11 000 codes. Don't hesitate to download it. It is free and, using an ELM327 or ELM323 interface, can be used to read the fault codes. For more details, go to our EOBD-Facile car diagnostic software page.

OBD-II (Check Engine Light) Trouble Codes Welcome to OBD-Codes.com, your headquarters for everything OBD-II related. For more information on what OBD codes are, OBD-II codes explained, explanation of fuel trims, or answers to other questions, visit our FAQ area. The most common OBD-II codes are P0___ powertrain codes, which are linked below on this page, along with P2___ generic & P3___ generic codes. Second most common seem to be P1___ powertrain codes, which are manufacturer specific. For the other OBD-II codes, choose from B**** - B Codes - OBD-II Body Codes or C**** - C Codes - Chassis Codes, and U**** - U - Network Codes. Generic Powertrain Trouble Codes This list contains standard diagnostic trouble codes (DTC's) that are used by all manufacturers to identify vehicle problems. The codes provide below are generic codes that may not apply to all vehicles. Vehicle manufacturers may use manufacturer specific DTC codes that differ slightly from the codes below. NOTICE: Due to the massive amount of codes in the listing, we have split them up into multiple pages. Choose the section of codes based on the first three characters of the code (e.g. P0171 is on the P01xx or P0100 through P0199 page): P0000 through P0099 P0100 through P0199 P0200 through P0299 P0300 through P0399 P0400 through P0499 P0500 through P0599 P0600 through P0699 P0700 through P0799 P0800 through P0899 P0900 through P0999 P0A00 through P0A99 P0B00 through P0B99 P0C00 through P0C99 P2000 through P2099 P2100 through P2199 P2200 through P2299 P2300 through P2399 P2400 through P2499 P2500 through P2599 P2600 through P2699 P2700 through P2799 P2800 through P2899 P2900 through P2999 P3000 through P3499
