About Engine Diagnostics
Beginning in the mid 1990’s, almost all passenger cars have been manufactured with on-board engine diagnostic equipment (OBD) or in simpler terms, your car’s computer. Onboard engine diagnostic equipment communicates with the electronic sensors all over your engine. The signals sent back to each specific system’s computer alerts you if engine repair or maintenance is necessary. Although the information provided to you is vague, it’s actually a very helpful safety feature.
How Does an Engine Diagnostic Work?
It's a simple process. Our equipment allows us to "speak" with your vehicle’s computer. Using professional, state of the art diagnostic equipment, we connect directly with the onboard computer of your vehicle. The software will interface with the vehicle computer to reveal a diagnostic code, which is cross-referenced with a database of manufacturer vehicle codes. The code provides needed information to accurately identify the problem and implement the proper solution. After we complete the diagnostic, we will provide you with an auto repair estimate. We will never do any repair work without your permission first.

- Bad spark plugs and wires
