Engine Diagnostic and Engine Repair Engine Diagnostic & Repair

It’s not like the old days anymore! Today's vehicles rely more than ever on their onboard computers to monitor and manage vital systems. Your average weekend mechanic does not have access to the engine diagnostic equipment or specialized tools needed to keep your car in top condition.

When you see the Check Engine Light, need an engine repair or simply want to schedule a car tune up, visit one of the 12 Virginia Tire & Auto locations across Northern Virginia or Main Street Shell in Fairfax to get the expert service you need.

What does the Check Engine Light mean?

Almost all passenger cars manufactured beginning in the mid-1990s on have on-board engine diagnostic equipment (OBD) — in other words, your car’s computers. Even though the Check Engine Light may seem be frustrating because it seems so vague, it’s actually a very helpful safety feature. A Virginia Tire & Auto engine repair expert has the tools and training needed to find out if that Check Engine Light is a quick fix or the sign of a larger issue.

Onboard engine diagnostic equipment communicates with electronic sensors all over your engine. The signals sent back to each specific system’s computer lets you know if engine repair or maintenance is needed. If you have loose caps, frayed wires or belts or any number of other issues that can affect the safety of you and your passengers, a signal is sent that activates the Check Engine Light on your dashboard.

Whether you’re running some quick errands or stuck in Northern Virginia’s notorious rush hour traffic, nothing puts a damper on the day like seeing your car’s Check Engine Light. Before panicking or canceling your plans, remember — there are many sensors on the engine, and a Check Engine Light can often have a simple, cheap repair. Schedule an appointment at Virginia Tire & Auto and we’ll help you relax.

Just bring your car into one of our 12 convenient Virginia Tire & Auto locations across Northern Virginia or Main Street Shell in Fairfax for a look.
