Will the check engine light reset itself?

The check engine light on your 2012 Ford Focus 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 productive, 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 2012 Ford Focus 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 David McDavid Ford so the light and code can be double-checked and reset.

What could cause the check engine light to come on in a 2012 Ford Focus?

When your check engine light comes on, this could be as pure as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a threatening problem that could cause threatening damage to your engine and come with a considerable repair bill. Depending on your make and model, the check engine light will illuminate or blink. A dependable glow generally means something less threatening but a flashing check engine light indicates that your vehicle’s engine is in threatening trouble and service is essential suddenly. If your check engine light is flashing in your 2012 Ford Focus, we incredibly recommend not to commute the vehicle and schedule Ford service at this moment. Below is a list of the most pure reasons your check engine light can come on:

  • Your 2012 Ford Focus has a vacuum leak. Every Ford Focus has a vacuum system that performs a wide 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 dehydrated out and crack, notably if they’re exposed to extraordinary heat or extreme chilly.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your 2012 Ford Focus if it’s not installed properly. These aftermarket elements and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound accepted, bring your Focus to Ford and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM elements first place might cost a little bit more but could save you money from having to get low work and damage caused by low installation work corrected.
  • The battery is low or dead. The battery in your 2012 Ford Focus is every awful. 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 truly require maintenance. The price of a new one depends on the type of Ford you drive, but check our current service coupons and specials.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your 2012 Ford Focus’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 commonly caused by neglected maintenance, which is why David McDavid Ford offers a complimentary multi-point inspection with every Ford service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Ford Focus 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 additional problems from overheating.
  • One of the most typical and frequent cause is that your 2012 Ford Focus gas cap is loose, damaged or missing. The gas cap for your 2012 Ford Focus 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 detrimental fuel cap? If your gas cap is classic 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 2012 Ford Focus, 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.
  • New Spark Plugs or Plug Wires are needed for your 2012 Ford Focus. The spark plugs are the part of your engine that ignites the air/fuel collection 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 detrimental or classic, you will experience low 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted 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 practical 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 2012 Ford Focus's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to read the polite collection of air and fuel that enters the cylinders in your engine. A detrimental 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 Ford Focus 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 big changes, like altitude. If your Ford Focus is having trouble starting, idling rough or has a hasty change in the position of the throttle pedal, this could be a sign of a detrimental mass airflow sensor.
