Introduction

The On-Board Diagnostics II (OBD2) system is a standardized system used in vehicles to monitor and control emissions. It provides a way for mechanics and technicians to diagnose problems with a vehicle's engine and other systems. The OBD2 system uses a set of standardized codes, known as Diagnostic Trouble Codes (DTCs), to indicate problems with the vehicle. In this article, we will discuss the OBD2 DTC lookup tool and how it can be used to diagnose problems with a vehicle.

What is OBD2?

OBD2 is a standardized system used in vehicles to monitor and control emissions. It was introduced in the United States in 1996 and has since become a global standard. The OBD2 system uses a set of standardized codes, known as DTCs, to indicate problems with the vehicle. These codes are used to diagnose problems with the engine, transmission, and other systems.

What are DTCs?

DTCs are a set of standardized codes used by the OBD2 system to indicate problems with a vehicle. They are used to diagnose problems with the engine, transmission, and other systems. DTCs are typically four-digit codes, with the first digit indicating the type of code (P0, P1, P2, etc.). The second digit indicates the category of the code (e.g. engine, transmission, etc.). The third and fourth digits indicate the specific problem with the vehicle.

Types of DTCs

There are two types of DTCs: Generic and Manufacturer Specific. Generic DTCs are used by all vehicles and are typically P0, P2, and some P3 codes. Manufacturer Specific DTCs are used by specific manufacturers and are typically P1 and some P3 codes.

ODB2 Database

The OBD2 database contains both Generic and Manufacturer Specific DTCs. It is constantly being updated to include more Manufacturer specific (P1) code definitions. Currently, the database contains code definitions for 45 different vehicle makes.
