The first step in having your check engine light diagnosed is knowing where to plug in your car code reader. These connectors are always present within the automobile, even if the OBD2 port’s placement can change depending on the make and model of your car.
The OBD2 port on your car is often located under the driver’s side dashboard.
The connector is typically found on the driver’s side of cars under the instrument panel, also known as the dashboard, while some cars have them in the center console or even on the passenger side. Additionally, some OBD2 ports are visible and simple to locate, while others are covered. Remember that since the connector is under the dash, getting low enough to locate it and connect your scan tool would probably require getting out of the car.
Consult your owner’s manual or type your vehicle’s information into our OBD2 port locator if you’re still having trouble finding your OBD2 port.

I want to utilize an OBD scanner.
Your vehicle is identified with a VIN (VIN). You may need to enter the VIN before your scanner can generate any OBD2 codes, depending on the scanner.
Other information, such as your engine and model type, may also be requested by the code scanner.
The VIN can usually be found on a sticker in the lower corner of the driver’s side windshield, if the scanner asks for it. Other locations are in the front of the car’s frame and under the hood near to the clasp.

What makes OBD and OBD2 different from one another?
Let’s first go over the definition of OBD in greater detail. The term “OBD” stands for “on-board diagnostics.” The second iteration of the onboard diagnostic system is known as OBD2.
The system in an automobile known as OBD, or onboard diagnostics, is responsible for monitoring and controlling all significant control devices while providing data access with the proper hardware and software.
The capacity of OBD to alert the reader to any fault codes or unusual actions with their car is an essential component. Diagnostic issue codes or fault codes are the names for these mistakes.
Normally, when a system error is discovered, it records the necessary error code in its memory and displays a warning light on the dashboard of the vehicle. This is what typically occurs when the bothersome check engine light comes on.
OBD 1The Predecessor
OBD1 was developed in the USA as a response to initiatives to lessen air pollution brought on by a rise in the number of cars in major cities. With the introduction of tighter pollution standards for gasoline-powered automobiles by the California Air Resources Board (CARB) in 1988, California took the lead in the effort to “keep the air clean.” Compliance was necessary for the duration of the vehicle, not simply while it was brand-new.
It was necessary to create an electronic self-monitoring system to enable compliance checks at any time, which led to the development of OBD1. The user was informed of an abnormal situation via a signal light.
It was adopted in 1994 by other states. However, OBD1’s largest flaw was non-standardization, as automakers developed and used their own methods, necessitating the need of numerous scanners to read various systems.
OBD2The Current Standard
The newly created OBD2 system was required to be installed in all new automobiles beginning in 1996 by CARB legislation, which was established in 1994. By using a common interface, this would enable the usage of a single OBD scanner across many automakers.
By doing this, it would be possible to monitor not only emissions regulations but also the entire exhaust-influencing system, which includes all of the many operations in a vehicle. The standardization produced a simpler trouble code reading process.
Via the year 2000, OBD2 had arrived in Europe, mandating that any emissions violations be notified by a dashboard warning light and error codes stored by the car.
Since 2001, all automobiles with Otto engines (petrol/gas engines) are required to have the OBD2 interface. Beginning in 2004, diesel automobiles were subject to these requirements.
Both auto repair shops and automobile aficionados found the new standard to be quite helpful. OBD scans can be expensive in terms of both time and money.
However, most individuals aren’t aware that OBD2 scanners are available for personal use, giving them complete control over their vehicle and repair costs.
How many OBD ports are there in a car?
A automobile you bought after 1996 is likely to have an OBD-II port. But what is it used for, and how does it work for mistake diagnosis?
It’s likely that your vehicle has an OBD-II (Onboard Diagnostics II) port if you bought it after 1996. After 1996, it became required by law to put one in every automobile and truck on the road.
An onboard computer called OBD-II keeps track of your car’s emissions, mileage, speed, and other information. It is associated with the Check Engine light, which turns on when a problem is found by the computer.
Under the driver’s side dash is a 16-pin port for the OBD-II onboard computer. It enables the use of a special scan tool by a mechanic or anybody else to read the fault code.
What functions may an OBD 2 port perform?
What an OBD-II Adapter Is Good For
- See how much gas each of your trips costs. The cost of filling your tank is probably something you can recall off the top of your head.
- Check the check engine light.
- Keep in mind where you parked your vehicle.
- Call emergency services for assistance.
- Join Alexa, IFTTT, and other intelligent applications.
What does the OBD port do?
The On-Board Diagnostics II (OBD-II) connector allows access to the vehicle’s computer for a variety of purposes, including diagnostics and emissions testing. The Hum System is put in the OBD-II port so that the network can speak with the car directly.
Is a running automobile required to utilize an OBD2 scanner?
Connect your OBD2 scanner to view what’s happening on when the check engine lights come on. You can find specific engine codes in the user handbook and use our scan tool to display them so you can identify what’s wrong.
But is starting your car’s engine necessary before you may use the diagnostic system? The short answer is no; all you have to do to give the scanner power is switch on the ignition.
But there is more to it than that. Push the power button to learn how to operate it, what you can and cannot do with it, and how to push it.
Can I leave my OBD2 connected?
Sorry to hear that your car is having problems! While driving, leaving an OBD2 scanning tool connected in is quite safe. In order to prevent harming the scanning software, it is crucial to have your automobile running while diagnosing an engine code.
Concerned about the life of your car’s batteries? Unless you leave your OBD2 scanner plugged in and don’t drive your car for several days, driving while it’s connected does not considerably drain the batteries. Unplug the scanner if you know you won’t be driving for more than a few days.
OBD2 scanners are getting more advanced because they include Bluetooth technology. However, just as with the older generations, you must be very careful when plugging and unplugging the scanner during operation.
The 16 pins on the plug allow the scanner to connect to the OBD2 port on your car. You should be careful not to bend or shatter the pins while installing the scanner because they are quite delicate. Do not insert a pin into the OBD2 port if it seems to be ragged or bent.

An OBD port can be found where on a 2004 Honda Civic?
Honda Civic 7 OBD connection location (2001 – 2005)
- Above the pedals on the right is where you’ll find the OBD II plug.
- On the top right of the gas, there is a hookup.
- The OBD II plug is located here.
What causes the check engine light to come on most frequently?
The oxygen sensor is the same way. This important component measures the amount of unburned oxygen present in your car’s exhaust, and if there is too little or too much, it may harm other engine components. Every time an oxygen sensor fails, a check engine light will come on. In fact, it’s among the most frequent causes of a check engine light appearing while you’re operating your car.
What distinguishes an OBD reader from a scanner?
Code readers are practical for mechanics and automobile owners who want to read and clear diagnostic codes because they are affordable and simple to use. While more expensive, scan tools include diagnostic tools, troubleshooting advice, data readouts, and the same functionality as code readers.
