Will the check engine light reset itself?

A check engine light will 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 direct, and you did assorted 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, the light will go off after about 20-40 miles. If you drive over that deposit and the light is still on, you will need to bring it in so the light and code can be double-checked and reset.

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

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, 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:

  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota is what determines how much fuel is mandatory 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 attentive changes, like altitude. If your Toyota is having trouble starting, idling rough or has a quick change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Toyota ’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 of Roswell 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 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 further problems from overheating.
  • New Spark Plugs or Plug Wires are mandatory for your Toyota. The spark plugs are the part of your engine that ignites the air/fuel difference 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 you're spark plugs or spark plug wires are bad or routine, 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, fresh 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 appropriate when it comes to fuel economy.
  • The battery is low or dead. The battery in you Toyota every visible. 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 assorted 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 amiable service coupons and specials.
  • 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 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to designate the noble difference 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.
  • Your Toyota has a vacuum leak. Every Toyota has a vacuum system that performs a wide difference of functions. The vacuum system also helps reduce harmful emissions by routing the fumes as gasoline evaporates through the engine. If you consider that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can parched out and crack, especially if they’re exposed to extraordinary heat or extreme crisp.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your Toyota if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound fresh, bring your 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 some 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 prevalent and bountiful cause is that your gas cap is loose, damaged or missing. The gas cap for your Toyota 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 routine 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 immediately after you put gas in your Toyota, first thing you should check is to make fearless the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
