In some cases, the check engine light may flash on and then go off on its own. In other cases, the light may remain on to warn you that your vehicle needs inspection by a qualified auto repair technician.
Not every automotive problem gives you obvious signals like hard starting, rough running, stalling, or odd noises. A Check Engine Light is often an indicator of minor problems before they become major (expensive) problems. It is very important not to ignore a Check Engine warning light!
Don’t ignore needed maintenance. Even something as simple as keeping up with oil change service can help your engine run cleaner and may prevent certain issues that trigger the Check Engine light.

Types Of Warning Lights
There are two main types of vehicle warning lights: the Check Engine Light and the Service Warning Light.
What is the difference between Service Engine Soon and Check Engine Lights?
"Service Engine Soon" and "Check Engine" are often used interchangeably to indicate a stored diagnostic trouble code, but they differ in what they monitor and their urgency.
A "Check Engine" light usually signals a direct malfunction, either an emissions or engine-related problem. Your vehicle is not only performing poorly, but it could also be polluting.
The "Service Engine Soon" light serves as a non-critical reminder of routine, mileage- or time-based scheduled maintenance (e.g., an engine oil change).
Vehicle warning light urgency is indicated by the light being on, either steadily or in a flashing state. A solid light indicates that a scheduled visit to the mechanic is required. In contrast, a flashing warning light indicates a serious problem (such as a severe misfire) that requires immediate attention to prevent damage to the engine or emissions system.
What causes the service engine soon light to come on?
The Service Engine Soon light primarily monitors vehicle maintenance, so there is no need to panic. Unlike the flashing Check Engine Light or the Charging System red warning light, which require an immediate engine shutdown, the Service Engine Soon light is an advisory reminder.
The Service Engine Soon light is yellow or orange, signaling caution. Even though the Service Engine Soon light doesn't indicate a serious problem, your vehicle is calling out for help and should be investigated as soon as possible.

How The Check Engine Light Works
Your vehicle's computer constantly monitors numerous engine sensor readings that measure its operating conditions. If the computer detects a problem, it will turn on the Check Engine Light to warn the driver that the vehicle needs to be inspected and the problem diagnosed.
When a sensor reading falls outside the normal operating range, the computer records a trouble code. If the problem is serious, the light is switched on immediately. If the problem is temporary or intermittent, the computer will record the error code and wait for it to occur again. If the problem recurs, the Check Engine Light will turn on and stay on until it is checked and reset by an auto repair technician.
Don't Ignore your "Check Engine" Light
Don't ignore Check Engine warning lights. Unlike a 'Service Engine Soon' light, a Check Engine Light requires attention as soon as safely possible. Red warning lights indicate a serious problem. Yellow or orange-colored warning lights, like the Service Engine Soon Light, are "advising" you of an issue that needs attention soon but not immediately.
Your vehicle's Check Engine warning light primarily monitors essential engine and electrical systems. Overheat, engine lubrication, or charging system warning lights are almost always indicative of a serious problem that requires the engine to be shut down as soon as safely possible. Turning off the engine can prevent serious damage.
If you need help repairing a Check Engine Light (CEL) problem in Ann Arbor, MI, Hoover Street Auto Repair has the diagnostic equipment and trained technicians to identify and fix CEL issues quickly.
Check Engine Light Repair and Diagnosis
Why does the problem need to be “diagnosed”? Doesn't the computer tell you what is wrong?
Some people think the trouble code stored by the vehicle computer will tell the auto repair technician exactly what is wrong. Unfortunately, troubleshooting is usually not that simple. The trouble code will tell the mechanic which sensor reading is out of normal range, but it cannot tell the technician why it is out of parameters. Trouble codes provide a starting point and help narrow down the possible causes of a Check Engine Light.
Some problems are very simple and easy to identify, while others are very complex with many different causes. The technician must use special diagnostic equipment and a time-consuming series of problem-solving steps to find the correct cause. Finding the source of the problem is a combination of training, experience, and the right tools.
Example: Let's say you feel terrible (your body's Check Engine Light is on). You get a thermometer (a heat sensor), put it under your tongue, and find that you have a fever of 104 degrees. You now know you have a fever, but you don't know what is causing it. It could be a sinus infection, appendicitis, or just the flu. Only a skilled professional, your doctor, can correctly diagnose the problem. The doctor will use their knowledge, experience, and tools to determine the cause of your fever and offer a solution.
How Do You Find The Right Check Engine Light Solution?
Leave it to the pros. Anyone can scan a vehicle for trouble codes, but only a certified, experienced auto repair technician can correctly diagnose the problem and repair it.
Hoover Street Auto Repair in Ann Arbor, MI, will accurately diagnose Check Engine Light issues and provide the best Check Engine Light repair for your budget.
Why Is A Complete Computerized Engine Analysis Worth Every Penny?
The computers in modern vehicles operate and monitor almost every system in the vehicle: air conditioning, radio, airbags, alarm, anti-lock braking, traction control, ride control, cruise control, instrument panels, transmissions, and, most importantly, emissions and engine controls. There is a wide range of warning lights that inform the driver of any problems with these systems.
Today, too many auto repair shops rely solely on the vehicle's self-diagnostic system. Instead of using proper troubleshooting procedures, some people trying to repair Check Engine Light problems, mostly do-it-yourself mechanics or less-skilled auto repair technicians, resort to trial-and-error parts swapping when they don’t know how to fix a warning light problem.
Diagnosis and repair of these complex electronic systems requires extensive training, experience, and expensive equipment to perform Check Engine Light service in Ann Arbor, MI, correctly and economically.
It is important to choose a shop that has experienced ASE-Certified Technicians and diagnostic equipment. Diagnosing modern vehicles without proper training and diagnostic equipment can lead to misdiagnosis, costing you hundreds, even thousands, of dollars in unnecessary repairs.
The major auto part manufacturers have reported that as much as 80% of all vehicle computers returned for repair were found NOT to be defective! For this reason, a proper check engine light analysis can save you money by correctly diagnosing your vehicle’s problems the first time!
