2017 Toyota Corolla Check Engine Light

What could cause the check engine light to come on in a 2017 Toyota Corolla?

When your check engine light comes on, this could be as authentic as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a unstable problem that could cause unstable damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow normally means something less unstable but a glaring check engine light indicates that your vehicle’s engine is in unstable trouble and service is needed suddenly. If your check engine light is glaring in your 2017 Toyota Corolla, we remarkably advise not to drive the car and schedule Toyota service suddenly. Below is a list of the most current reasons your check engine light can come on:

• Your 2017 Toyota Corolla has a vacuum leak. Every Toyota Corolla has a vacuum system that performs a wide variety of functions. The vacuum system also helps rebate 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 bare out and crack, especially if they’re exposed to imposing heat or extreme cold.
• 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 needed 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 correct 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or precise item can wreak havoc on your 2017 Toyota Corolla if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound amiable, bring your Corolla to Toyota and have our unit of certified mechanics ensure that your aftermarket items were installed properly 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.
• One of the most logical and frequent cause is that your 2017 Toyota Corolla gas cap is loose, damaged or missing. The gas cap for your 2017 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 quickly after you put gas in your 2017 Toyota Corolla, first thing you should check is to make sure 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 2017 Toyota Corolla’s exhaust system. The catalytic converter's function 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 Nalley Toyota Stonecrest offers a complimentary multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 2017 Toyota Corolla will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause precise problems from overheating.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, logical 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 car will be less accessible when it comes to fuel economy. 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 2017 Toyota Corolla's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
• The battery is low or dead. The battery in your 2017 Toyota Corolla is every threatening. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance. The cost of a new one depends on the type of Toyota you drive, but check our brand-new service coupons and specials.
• New Spark Plugs or Plug Wires are needed for your 2017 Toyota Corolla. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. 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 some 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.

Will the check engine light reset itself?

The check engine light on your 2017 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 noteworthy, 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 2017 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 deliver it in to Nalley Toyota Stonecrest so the light and code can be double-checked and reset.
