Why is my Check Engine Light on?!

The Check Engine Light strikes fear into the hearts of so many Cartersville, drivers and is totally ignored by just as many, but just what does it mean? It is a big mystery to most people and it can be very dangerous to your vehicle's Engine. Let's get a better understanding of what the Check Engine Light does and what it usually indicates.


Let's get the urgency issues out of the way first. If your Check Engine light is flashing, that means that something is wrong that could cause serious engine damage. This usually indicates the engine is misfiring or skipping on one or more of its cylinders. You need to get this diagnosed and taken care of right away. If your check engine light is flashing, you shouldn't drive at high speeds, tow or haul heavy loads. Drive slow and straight to the nearest Cartersville, Best Auto Repair Experience service center.

Why

If the light is glowing steadily, you should still get it checked out, however, it's probably not something that will leave you stranded right away. Monitor the vehicle, and if the light doesn't go off, or the vehicle starts running poorly, schedule an appointment with the friendly and knowledgeable professionals at Best Auto Repair Experience to get a proper diagnostic test performed.

Some more information on how the Check Engine light works may be helpful for drivers. Most of your engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine running conditions, fuel quality, and even driving habits.

In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range, the computer runs some tests and may turn on the vehicle's Check Engine light if one of the sensors are reading out-of-range.

A simple example is a loose or missing gas cap. This may cause one of the Evaporative Emissions sensors to read out of range. The computer doesn't know if it's a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine light, and continuously monitors for the fault to be present.

Now when you tighten up the gas cap, the sensor readings will be in the correct range. The computer continuously monitors these circuits and readings. Since the inaccurate reading didn't come up again, it turns off the Check Engine light. The computer will also try to make adjustments to compensate other readings. If it can do so, it'll then will turn off the Check Engine light.

If the problem wasn't resolved by tightening the gas cap, then the light will remain on, and you should get your vehicle looked at as soon as possible. This indicates you have a hard fault and it will require a trained professional to diagnose the Check Engine Light properly. The ASE Certified Technicians at Best Auto Repair Experience have the proper diagnostic scanners and software to read the diagnostic trouble codes stored in the computer. The trouble code will give the technician a starting place as they diagnose the cause of the Check Engine Light. Once the technician performs a complete diagnostic test, they will be able to better advise you on the necessary repairs and course of action to take. Get it diagnosed right the first time, get it fixed right the first time!
