What year did cars have OBD2 port?
As a seasoned auto repair professional, I often get asked about the history and evolution of vehicle diagnostic systems. One of the most significant advancements in automotive technology was the introduction of the OBD2 (On-Board Diagnostics II) port. This article will explore when OBD2 ports became standard in vehicles and why they are essential for modern car maintenance and repair.
The Introduction of OBD2 Ports
OBD2 ports became a mandatory feature in all cars and light trucks sold in the United States starting in the model year 1996. This requirement was established by the Environmental Protection Agency (EPA) as part of efforts to standardize emissions control systems and improve vehicle diagnostics. The regulation ensured that all vehicles would have a universal diagnostic system, making it easier for mechanics and car owners to identify and address issues.
Why Was OBD2 Introduced?
The introduction of OBD2 was driven by several key factors:
- Environmental Concerns: OBD2 systems monitor emissions-related components, helping to reduce harmful pollutants released into the atmosphere.
- Standardization: Before OBD2, manufacturers used proprietary diagnostic systems, which made it challenging for independent mechanics to service vehicles. OBD2 created a universal standard.
- Improved Diagnostics: The system provides detailed diagnostic trouble codes (DTCs) that help pinpoint specific issues, saving time and money during repairs.
How to Identify an OBD2 Port
If you own a car manufactured in 1996 or later, it will have an OBD2 port. Here’s how you can locate it:
- Look under the dashboard on the driver’s side. The port is typically located near the steering column.
- It is a 16-pin connector, often uncovered and easily accessible.
- If you’re unsure, consult your vehicle’s owner manual for the exact location.

Frequently Asked Questions
When did they start putting OBD ports in cars?
In 1991 the state of California mandated that all vehicles have some form of basic on-board diagnostics. This is known as OBD-I, a precursor to the OBD-II port. OBD-II was created three years later, in 1994.
When did cars switch from OBD1 to OBD2?
1996
OBD-II became the nationwide standard in 1996. Compared to OBD-I, OBD-II is improved in standardization and capability. The standard OBD-II specifies the diagnostic connector and the corresponding pinout has electrical signal protocols and includes a messaging format.
How do I know if I have OBD1 or OBD2?
The OBD connector is a 16-pin connector that is usually located under the dashboard on the driver's side. If your car has a 16-pin connector, then it has OBD2 or EOBD. If your car has a different type of connector, then it has OBD1. You can also check your car's owner's manual to find out which OBD system your car has.
Do older cars have an OBD2 port?
OBD stands for On-board diagnostics. The two main types of diagnostic systems in vehicles is OBD1 and OBD2. OBD1 was used in vehicles up to as late as 2006 and anything newer will be OBD2. Some vehicles manufactured earlier than 2006 are still OBD2 For example: You own a 2003 Toyota Corolla, this is OBD1.
Do 1999 cars have OBD2?
All 1996 and newer model year gasoline and alternate fuel passenger cars and trucks are required to have OBD II systems. All 1997 and newer model year diesel fueled passenger cars and trucks are also required to meet the OBD II requirements.
Is my car OBD1 or OBD2?
The OBD connector is a 16-pin connector that is usually located under the dashboard on the driver's side. If your car has a 16-pin connector, then it has OBD2 or EOBD. If your car has a different type of connector, then it has OBD1. You can also check your car's owner's manual to find out which OBD system your car has.
Does a 1995 car have OBD2 port?
All 1997 and newer model year diesel fueled passenger cars and trucks are also required to meet the OBD II requirements. Additionally, a small number of 1994 and 1995 model year gasoline vehicles were equipped with OBD II systems.
What year was OBD2 mandatory?
1996
OBDII included a series of standardized diagnostic trouble codes (DTCs). 1996 — OBD-II becomes mandatory for all cars manufactured in the United States.
Do all 1996 cars have OBD2?
All 1996 and newer model year gasoline and alternate fuel passenger cars and trucks are required to have OBD II systems.
Do 1998 cars have OBD2?
1996 or newer model year vehicle sold in the United States
United States legislation requires all cars and light trucks model year (MY) 1996 and newer to be OBD2 compliant.
