Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your Toyota Corolla, we extremely advocate not to drive the vehicle and schedule Toyota service now. Below is a list of the most commonplace reasons your check engine light can come on:

• Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 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 Union City 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 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 substitute problems from overheating.
• Your Toyota Corolla has a vacuum leak. Every Toyota Corolla has a vacuum system that performs a imposing range of functions. The vacuum system also helps reduce 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 dry out and crack, highly if they’re exposed to imposing heat or extreme immediate.
• 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 mixture in the combustion chamber of your automobile. This explosion is what moves the pistons and makes the engine run. The spark plug wires transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or traditional, you will experience scanty 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, major to more expensive repairs.
• One of the most normal and bountiful 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 harmful fuel cap? If your gas cap is traditional 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 today after you put gas in your Toyota Corolla, initial 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.
• The battery is scanty or dead. The battery in your Toyota Corolla is every imposing. 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 explicitly require maintenance. The value of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
• 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 elements and accessories can drain the battery, trigger the check engine light, or even avoid the automobile from starting. If these issues sound admitted, bring your Corolla to Toyota and have our squad of certified technicians ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM elements initial place might cost a little bit more but could save you money from having to get scanty work and damage caused by scanty installation work corrected.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, noted 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 automobile will be less competent 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 Toyota Corolla's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
• 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 bold 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 harmful mass airflow sensor.
