Check Engine Light Service Toyota Corolla

What do you do when you’re driving along in your Toyota Corolla and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Toyota owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your Toyota Corolla checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Toyota Corolla's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Toyota auto repair mechanics at Coggin Toyota at the Avenues. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.

Is it safe to drive your Toyota Corolla with the check engine light on?

This question is not extraordinarily contrasting because it all depends on the severity of the issue. If the cause is a minor issue, such as a loose gas cap, it should be safe to drive.

If the check engine light is flashing, this means that there is a precarious issue and it is recommended to service your Toyota Corolla immediately. Call the specialists at Coggin Toyota at the Avenues by dialing 9043376618 so you can describe the issues.

Will the check engine light reset itself?

The check engine light on your Toyota Corolla will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Toyota Corolla light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Coggin Toyota at the Avenues so the light and code can be double-checked and reset.

What could cause the check engine light to come on in a Toyota Corolla?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle’s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Toyota Corolla, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

• The battery is scanty or dead. The battery in your Toyota Corolla is every curious. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't really require maintenance. The price of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
• New Spark Plugs or Plug Wires are decisive for your Toyota Corolla. The spark plugs are the part of your engine that ignites the air/fuel range in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or aged, you will experience poor performance and reduced power. In a few extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, first-rate to more expensive repairs.
• Your Toyota Corolla has a vacuum leak. Every Toyota Corolla has a vacuum system that performs a gargantuan variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can arid out and crack, especially if they’re exposed to imposing heat or extreme cold.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your Toyota Corolla if it’s not installed properly. These aftermarket parts and accessories can dump the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound prominent, bring your Corolla to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, prominent as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less productive when it comes to fuel economy.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Corolla is what determines how much fuel is decisive to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to keen changes, like altitude. If your Toyota Corolla is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
• One of the most practical and countless cause is that your Toyota Corolla gas cap is loose, damaged or missing. The gas cap for your Toyota Corolla serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is aged or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on shortly after you put gas in your Toyota Corolla, first thing you should check is to make hopeful the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Toyota Corolla’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Coggin Toyota at the Avenues offers a complimentary multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it revamped, your Toyota Corolla will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause substitute problems from overheating.
So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your Toyota Corolla's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the honest range of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.
