Car diagnostic code readers have gone a long distance from what they used to be, let's talk about a some history and bring you up to the times. Auto readers, commonly known as auto scanners or OBD scan stands are devices that are hand held that are inserted into an OBD port to help identify the vehicle engine and problems associated with emissions.
Vehicle OBD scanners plug right into a port that is found directly under the dash of every U.S. created cars after the year 1996. Most commonly referred to as OBDII cars, before 1996 things weren't uniform and vehicle manufacturers had various methods and car diagnostics to figure out problems. Just about all cars developed after the year 1996 were feeded with an OBDII system that allows universal codes reader to help figure out problems with the engine. The overall main difference between on board diagnostics 1 and 2 system is the creation of a universal code diagnostic system.
The introduction of on board diagnostic readers helped ease the issues of diagnosing and solving engine related issues by standardizing the onboard diagnostic system. Allowing for car code readers to display the same code regardless of the engine model or auto manufacturer.
Once plugged in an vehicle on board reader, live data corresponding to your aut engine and autos specifications will appear on the LCD screen of the scanner. This reader can also be used to check the CEL (check engine light) and provide other specs associated to the the autos fuel injector as well as o2 sensor related info. The most important important benefits of the OBD reader is how it can look at your engines emission readings and identify whether its in compliance with state mandated smog emission.
If a failure is identified that occurs to the engine and or emission, that sometimes is related to the o2 sensor, temp gauge, it will be logged and will be recorded to the on board readers DTC or better known as the diagnostic trouble code. This problem code is usually an indication that something in the engine or emission system is wrong. This will help you identify and further diagnose what exactly is causing the problem. Remember that this doesn't mean that a part needs to be swapped, instead that it could be something like a bad sensor and/or a block in the flow that is the root of the unusual readings. This helps you find the root of the issue, which will decrease the overall time spent with different vehicle issues.
Vehicle readers are connected to a computer port of your computer to further understand even more information which will help you better understand where the problem is occurring and how to best combat that. OBD computer diagnostic tools are needed for any car owner freaks or shop owner and they usually cost somewhere between $140 - $423. This is extremely cheap in comparison to replacing parts that don't need to be replaced. A lot of diagnostic checkups offered by autoshops use these standard tools and charge around $150 for a car review.
There are two types of OBD readers for sale right now, most of which are primarily handheld devices, the first is an on board diagnostic I reader and the other that is an OBDII reader. The second edition of the OBD readers are usually less expensive than OBDI because of the universal capabilities of the readers versus the specialized readers needed in an on board diagnosis I auto. Usually editions that are between 1991 - 1995 manufactured by General Motors, Ford and Chrysler, they manufactured a simple universal codes for the vehicles although these autos have a different example of connector when comparing to other cars created with the on board diagnosis I type of system.
