Expert Check Engine Diagnostics, Repairs, and Maintenance

The check engine light is triggered by the output from your onboard computer diagnostic system. Its single purpose is to inform you of situations that need to be addressed. Your vehicle’s problem could be a loose gas cap or a bad spark plug. It could be something more complicated like a malfunctioning catalytic converter.

When your check engine display lights up, it always involves a problem that reduces your car’s performance, lowers your fuel efficiency or increases toxic emissions. It’s important to have a certified technician run check engine diagnostics and complete repairs to eliminate small problems before they get worse.

Check Engine Diagnostics Problems and Options

What are the signs that a vehicle needs check engine diagnostics?
  • Check engine dash light illuminates
  • Check engine light flashes
  • Toxic exhaust fumes
  • Poor gas mileage
Is there a problem if the check engine light flashes when I start my car?
When you start your car, it runs internal diagnostic tests to make certain that everything is operating properly. All dashboard warning lights may flash briefly. As long as they fade out right away, there’s no cause for concern.

Is your Check Engine Light on?

It’s not unusual for your vehicle’s check engine display to light up. At any given time, 13% of all vehicles on the road have a check engine light issue. It’s possible that your light is signaling a relatively minor problem. In fact, 40% of all check engine light illuminations are caused by faulty Oxygen (O2) sensors.

When your check engine light shows that your vehicle needs attention, it’s best to take your car for service right away. At Roggi’s Auto Service, we prefer to repair your vehicle’s minor issues now before they become big expensive problems later.


CarMD research reveals that the check engine light is illuminated in 13% of all vehicles on the road. 9 million motorists have ignored their check engine lights for 3 months or more.

“These guys are the best locally, and while my experience is for a foreign car, they certainly know domestic too. I’ve a vehicle w/265k miles on it & had it in for work 2x over the past 3 weeks – totally unrelated issues. Henry and Wayne – and the entire team – are thoughtful, responsive and communicative. They explain the issue and work within whatever parameters I’ve had. Good car repair is not terribly hard to find but GREAT is another story. Roggi’s falls into the GREAT category!”
