Almost everyone is familiar with the dreaded check engine light that occasionally pops up on the dashboard. When that light turns on, your car’s engine computer also stores a corresponding diagnostic trouble code (DTC) in its memory.
There are thousands of codes, each of which has a unique definition. Codes that are defined by the Society of Automotive Engineers (SAE) are referred to as generic on-board diagnostic (OBD) 2 codes. There are also manufacturer-specific codes that are defined by the automaker.
What are OBD-II Codes?
Your car is equipped with what is officially known as an On-Board Diagnostics (OBD) system. In 1996, automakers implemented a universal system for these diagnostic codes known as OBD-II, which mandated that all vehicles have a common connector to access vehicle information.
On-board diagnostics essentially refers to a central computer system, a network of sensors throughout the vehicle, and a connection point through which vehicle information is accessed.
When combined, the OBD system gives you a glimpse into the workings of your car and alerts you to any issues that arise with the motor, transmission, vehicle electronics, and any other vehicle system.
When a fault occurs, the OBD-II system records the engine’s operating conditions in what is called “freeze frame data.” Freeze frame data represents a single frame of information and is stored in the system’s memory until the code is repaired or cleared.
However, if faults of higher priority, such as hard codes affecting the catalytic converter or engine, occur before the original code is resolved, the original freeze frame data may be overwritten by the hard code and its freeze data. This is found in the Freeze Data Mode $02 which requests freeze frame information.
What Does On-Board Diagnostics Mean?
On-board diagnostics (OBD) is a term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems.
The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers.
Early versions of OBD would simply illuminate a malfunction indicator light (MIL) or “idiot light” if a problem was detected but would not provide any information as to the nature of the problem.
Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle.
What are Diagnostic Trouble Codes?
Diagnostic Trouble Codes (DTC) are the codes generated and stored by the Powertrain Control Module (PCM) when the Onboard Diagnostic (OBD) system indicates a malfunction.
Simply put, when your car system diagnoses that something went wrong, it will send a code indicating the specific fault. Following a fault manual issued by the Society of Automotive Engineers (SAE), the DTC Codes tell you what the problem is and helps further diagnosis.
In 1996, a regulation about OBD and DTC codes was made mandatory for all cars sold in the United States. It specifies the standard of OBD ports and a fault code manual for all cars, which is referred to as OBD-II.
With this standard, it’s much easier to understand car malfunctions, and facilitates some DIY diagnosis and fixes of vehicles.
Where Is The OBD-II Port Located?
In a typical passenger vehicle, you can find the OBD-II port on the underside of the dashboard on the driver’s side of the car. Depending on the type of vehicle, the port could have a 16-pin, 6-pin or 9-pin configuration.
The port is usually located under the dashboard or beneath the steering wheel column. If not located beneath the steering column, look for the port in the areas indicated in the image.
What’s The Difference Between an OBD And OBD-II?
An OBD-II is, simply put, the second generation of an OBD or OBD I. The OBD I was initially externally connected to the console of a car, while the OBDII is now integrated within the vehicle itself. The original OBD was used until OBD-II was invented in the early 1990s.
How Does OBD-II Work?
Diagnostic Trouble Codes (DTC) are stored in the computer system. Codes can vary from one manufacturer to another. However, anyone with an OBD-II scan tool can connect to the OBD-II port and read the diagnostic trouble codes from the computer.
Special scanners can connect to these ports on your vehicles and identify trouble codes from any manufacturer that uses one of the OBD-II protocols. Any OBD-II scan tool can read the codes because of the standardized pinout, which is as follows:
Pin 1: Used by the manufacturer.
Pin 2: Used by SAE J1850 PWM and VPW
Pin 3: Used by the manufacturer.
Pin 4: Ground
Pin 5: Ground
Pin 6: Used by ISO 15765-4 CAN
Pin 7: The K-Line of ISO 9141-2 and ISO 14230-4
Pin 10: Used only by SAE J1850 PWM
Pin 14: Used by ISO 15765-4 CAN
Pin 15: The K-Line of ISO 9141-2 and ISO 14230-4
Pin 16: Power from the car battery
How do you read an OBD-II DTC?
DTC codes are five characters long. Each character in the DTC provides a different piece of information about the vehicle’s problem.
OBD II Codes List/DTC Codes Lists
Standard trouble codes start with P, then a four-digit numeric code. See the table below for a few common vehicle error codes and what they signify:
| DTC Codes | Description | Common Codes Within This Range |
| P0100-P0199 — Fuel and Air Metering | These codes are used to monitor the fuel and air ratio of the vehicle’s engine to determine if an oxygen sensor is failing, plus they will monitor a vehicle’s emissions and fuel economy. | P0135: O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). P0141: O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2). P0171: System Too Lean (Bank 1). P0174: System Too Lean (Bank 2). |
| P0200-P0299 — Fuel and Air Metering (Injector Circuit) | These codes are going to involve fuel injectors. | P0200: Injector Circuit Malfunction. P0218: Transmission Over Temperature Condition. |
| P0300-P0399 — Ignition System or Misfire | These codes will trigger if there are issues with the car’s ignition. For example, if there are spark plug issues. | P0300: Random/Multiple Cylinder Misfire Detected. P0301: Cylinder 1 Misfire Detected. P0302: Cylinder 2 Misfire Detected. P0303: Cylinder 3 Misfire Detected. P0304: Cylinder 4 Misfire Detected. P0325: Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor). |
| P0400-P0499 — Auxiliary Emissions Controls | These codes will determine issues with the system’s EVAP (evaporative emission control) systems.
