CHECK ENGINE LIGHT 

Is your Check Engine Light on?

The check engine light or service engine soon lamp is illuminated to alert the driver about the need for service. Although your car may seem to run fine now, your cars computer or Power Train Control Module (PCM) is trying to tell you something when that little light comes on. There are many sensors and computerized components that need to be working properly in order for your computer to manage your vehicle’s engine performance and emissions. When one of these components fails, or wears to the point where the PCM can no longer make the needed adjustments, that check engine light may illuminate, every time you start and operate your car.

We apply strategy based diagnostics to be able to pinpoint exactly what's going on with your vehicle!

What do the stored engine trouble codes mean?

Each system on your vehicle is assigned a series of code numbers and letters that help us determine where your computer saw a problem that caused it to turn the light on. Keep in mind, these codes don’t tell us exactly what failed, only what system the computer recognized a problem with.

Think of it like this; if you felt sick and your thermometer was reading 101 degrees, that only alerts you to the fact that you have a fever. Your fever could be from an infection, a virus or some other internal cause that would require more testing by your doctor to determine what is wrong with you and how it should be treated.

Well, your engine also has a thermometer and if it was reading too high, your computer would turn on the check engine light to alert you about it. With a cars computer, it can tell our certified, ASE master mechanics exactly what the trouble is, and where to look to further diagnose the issue.

The trouble codes from your check engine light could be related to multiple engine and transmission control systems such as:

  • Air Fuel Metering
  • Fuel Injector Malfunctions
  • Ignition System Misfires
  • Emission Controls
  • Vehicle Speed Control & Idle Control
  • Computer Output Controls
  • Transmission controls

Plus many more engine codes. And the numbers of codes for each of these systems can add up to over a thousand possibilities! So, understanding that the first place to start is to retrieve the stored codes, and then we can develop a strategy to properly diagnose the problem to save time and expense.

Check Engine Light Equipment For Your Make and Model

It’s important to have the right equipment to not only access your computers codes, but to also work with your PCM to find the relevant data for the affected system. A vehicle test drive with our computer scanners plugged in will show us what your cars computer is seeing when problems are occurring. Once we know the engine trouble codes, we can get to the root cause and prescribe the correct repair.

Engine Diagnostics and Performance

All vehicles built since 1996 in the United States are equipped with a standardized On-Board Diagnostics System (OBD 2) that monitors engine performance. Discrepancies in performance levels are reported through your vehicle’s computer system. Once the “check engine” or “service engine” light is displayed, your next step should be to seek out an engine diagnostic service or an engine tune-up. Strategy bases engine diagnostics allow our staff to gather helpful information about the operating condition of your engine. The insights obtained during an engine diagnostic will determine the extent of suggested engine repairs. The most common diagnostic trouble codes are generated in response to malfunctions in the powertrain. Ultimately, regular engine tune-ups and scheduled maintenance are necessary to optimize engine performance. A tune-up is also one of the most effective ways to prevent unexpected engine trouble. During an engine tune-up, our staff may replace the spark plugs, spark plug wires, air filter, fuel filter, and distributor cap and rotor in your vehicle (if equipped). Our experts will also inspect fuel lines, belts, hoses and fluids. Engine diagnostics and regular engine tune-ups can help extend the life of your vehicle and improve the health of your engine.

Benefits of Engine Diagnostics and Performance

While performing regular scheduled engine maintenance will help ensure that your engine always performs at peak conditions, there are also warning signs you can look for that indicate an engine diagnostic or repair is needed. The “check engine” or “service engine soon” light is a sure sign that your engine should be looked at by an expert sooner than later. Most of the time, your vehicle’s On-Board Diagnostics System will detect an engine issue and store the corresponding repair code, which can be accessed by a member of our service staff. Slow-cranking, rough idling, stalling, knocking, or pinging while accelerating are all signs that you should seek engine repairs or engine diagnostics to determine the full extent of your engine trouble. A decrease in gas mileage and detectable loss of power during acceleration are also signs of an impending engine tune-up or engine repair service. Engine warning lights help alert drivers to minor issues before they become major repairs. Be sure to follow up with our staff once your vehicle's On-Board Diagnostics System detects a problem with your engine.
