If you're driving along and your "check engine" light comes on, it is time to get an auto diagnostic check. An auto diagnostic check can show a number of issues going on with your oil tank, transmission, exhaust system, engine, and more. Modern cars have numerous computer chips and sensors that communicate with the diagnostics system and allow mechanics to narrow down exactly where an issue is happening with your car. Certified mechanics are able to perform the check quickly and professionally and recommend service in order to correct the problems using a hand-held device that performs the scan. Here's what a diagnostic test can do:

It can tell you if you have ignition timing problems, if there is buildup inside your engine (due to gunky byproducts of the combustion cycle), and if your fuel injectors are performing accurately. All of these are vital to keep your car running smoothly. In addition, it can detection issues with ignition coils, rpm rates, coolant and air temperatures, throttle opening, crankshaft positioning, and more. The test stores unique codes and informs the technician about the exact problem and location, allowing them to save time (and save you money) by taking care of the issue faster than traditional methods.

If you fail to run a diagnostic test, numerous problems could a rise. Your engine could overheat, your transmission could start slipping and grind the gears to the point of disrepair, and your exhaust could begin to backfire. Not only are these problems costly and inconvenient, they can also be dangerous. Imagine driving on the highway and losing control of your vehicle due to a neglected issue.

While many people avoid car checkups and repair because of the perceived cost, it is actually much more expensive to allow problems to build up into larger issues. A diagnostic test is very effective, meaning you could save hundreds or even thousands of dollars for a relatively small investment.

Auto diagnostic checks are a relatively new phenomenon. Before the invention of this useful procedure, mechanics would be forced to spend costly hours looking for the problems in your car - if they even found the source at all. That old-fashioned method costs you not only time but money. Qualified technicians are incredibly valuable and they are compensated as such. Make sure that your trusted technician is using their valuable time fixing the problem by letting quick and easy auto diagnostic checks find the problem.
