Services
Your car has a powerful electronic onboard diagnostics system (OBD II / pre 1986 OBD) that controls and regulates vehicle performance including engine speed (RPM), fuel mixture, emissions, ignition timing and automatic transmission shift times.
The system is very complex and in instances where the electronic-control system can't correct an issue, the computer illuminates the yellow "Check Engine", "Service Engine Soon" or "Check Power train" light (sometimes it's a simple engine picture).
The OBD II system then stores a "trouble code" in its memory that categorizes the source of the problem, such as a malfunctioning sensor or a misfiring engine.
Keeping up with yearly vehicle inspection ensures that your car operates safely and meets Pennsylvania's emissions requirements.
Our PA Certified Inspection Mechanics will thoroughly inspect your vehicle (including lights, brakes, horn, tires, safety belts, exhaust system, mirrors, tag mounting, suspension, turn signals, steering, glazing & wipers) according to the specifications set by Pennsylvania Department of Transportation.
Our PA Certified Emissions Mechanics will examine your car's systems (including ignition, air induction, fuel metering, early fuel evaporative, air injection, positive crankcase ventilation, evaporative emission control, exhaust gas recirculation, and exhaust gas conversion).
