How to Troubleshoot Auto Diagnostics Problems

August 2, 2017 10:03 pm Published by Leave your thoughts

Vehicles are one of the most substantial investments that most individuals will make over the course of their lifetimes. Due to the vast amounts of use that they experience from most drivers, however, vehicles are extremely susceptible to a wide range of mechanical problems and failures. Understanding how to diagnose these problems is the first step in treating them. Auto diagnostic repair in Port Charlotte, FL, however, can be a difficult thing to master.

Most modern vehicles are comprised of a complex set of mechanical and electronic components that are in constant communication with each other. Sometimes, your car can be rendered immobile by something as simple as a faulty switch or wire. This mechanical interdependence does carry benefits, though, as it makes it easier to properly diagnose malfunctioning vehicles.

All vehicles sold in the United States since the early 1990s include on-board diagnostics (OBD-II) ports that can be used to tell mechanics lots of information about the health of your engine. OBD-II ports are connected to your vehicle’s central computing unit, which is responsible for orchestrating the coordination of all of your car’s moving and stationary parts.

When a check engine light or other indicator light illuminates on your dashboard, this is an action caused by your car’s central computing unit. Determining exactly what issue is causing your vehicle to malfunction, however, requires the use of a OBD-II port reader, which has become a standardized and easy-to-use piece of technology that is found in mechanics’ shops throughout the country.

Port readers will display an error code, or a series of error codes, which savvy mechanics can use to diagnose exactly what is going wrong with your vehicle. While this process may seem deceptively easy, it still requires an extensive knowledge of the meaning of the more than 3,000 universal codes, in addition to manufacturer-specific codes.

Computer problems

Computers will only be able to provide mechanics with a rough outline of the problem at hand, and actually fixing your vehicle always requires a substantial amount of investigation on their part. Auto diagnostic repair in Port Charlotte, FL is a deeply involved process that requires the use of several highly specialized tools.

For instance, if a specific part of your vehicle is consistently giving error codes to an OBD-II port reader, it may be a problem with the computer sensor rather than the engine component itself. Mechanics can use multimeters to examine the electrical current that is being put out by the sensor, and determine if it is indeed the sensor that is at fault.

Similarly, some on-board computers may not be capable of detecting exactly where an air or vacuum system seal is broken. Mechanics can use a vacuum pressure gauge to pinpoint exactly which part of your car’s tube system is in need of replacing.
