Engine Analysis

Computerized Engine Analysis

Your modern vehicle's engine is a highly sophisticated piece of equipment. The days of your father's gas-guzzler are long gone—instead, Federal Exhaust Emission and Fuel Economy regulations demand that today's vehicles be equipped with electronic engine control systems, to curb carbon emissions and increase fuel efficiency. With technically-advanced control systems taking the place of simple engine components, common maintenance services such as tune-ups are also a thing of the past. Regular services (such as spark plug and filter replacements) are still required, as well as a computerized analysis of your vehicle's control computer. Our factory-trained technicians are here to provide these basic services.

Here's how your modern vehicle's control computer operates:

A network of sensors and switches convert and monitor engine operating conditions into electrical signals. The computer receives this information, and, based on information and instructions coded within this savvy computer program, it sends commands to three different systems: ignition, fuel, and emission control. When a problem arises—the "check engine" light turns on—our service pros checks it out. Bring in your vehicle, we'll check it out, and you can know if the "check engine" is a real problem, or just a sensor/computer issue.

Here's a brief overview of your vehicle's sensory components:

•Mass airflow sensor 
•Throttle position sensor 
•Manifold absolute pressure sensor 
•Coolant temperature sensor.

Check Engine Light

Your Check Engine Light (CEL) warns you that your vehicle's computer found a malfunctioning component in your emission control system. You may see "check engine," "service engine soon," or "check powertrain." Or, the light may show an engine picture, perhaps with the word "Check." To determine the actual problem, we use an electronic scan tool or a diagnostic computer to retrieve Diagnostic Trouble Codes (DTC). Some common issues that turn on the check engine light include: 
•Your gas cap isn't on tight enough; we suggest checking before calling us 
•Water got into your engine somewhere 
•The spark plugs don't function correctly 
•Your vehicle is emitting high levels of pollutants 

In any case, you should bring your vehicle to us, and we can inspect your vehicle, diagnose the problem, and take care of it. Leaving your engine light on can cause serious problems with your car in the long run. 

A check engine light appointment goes pretty fast, so stop by or give us a call.
