If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your Accord. There are hundreds of disparate codes that your check engine light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you appropriate knowledge about your vehicle and will also allow that Check Engine Light to do what it is certainly supposed to do: be your guide.

Since there are hundreds of probable OBD codes, there are also hundreds of probable reasons for the light, including:

  • Old Battery
  • Ignition system faults
  • Transmission issues
  • Fuel and air metering systems problems
  • Emissions controls issues
  • Computer output circuit issues
  • O2 Sensor

The fear of the unknown (or the cost of the unknown) can be just as stressful.

Ignoring that warning could end up causing large damage to expensive engine parts.

When your 2012 Honda Accord's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t polite, a computer turns on your check engine light. This amber or yellow light is consistently 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 audit tool that is used by our Honda auto repair mechanics at David McDavid Honda of Irving. There are also a number of somewhat inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too.

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 serious problem that could cause serious damage to your engine and come with a generous 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 2012 Honda Accord, we highly recommend not to commute the vehicle and schedule Honda service today. Below is a list of the most present reasons your check engine light can come on:

  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less realistic 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 Honda Accord's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the right mixture 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.
  • One of the most prevalent and frequent cause is that your 2012 Honda Accord gas cap is loose, damaged or missing. The gas cap for your 2012 Honda Accord 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 promptly after you put gas in your 2012 Honda Accord, first thing you should check is to make satisfied 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 Honda Accord. The spark plugs are the part of your engine that ignites the air/fuel mixture 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 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, considerable to more expensive repairs.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your 2012 Honda Accord’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 mostly caused by neglected maintenance, which is why David McDavid Honda of Irving offers a complimentary multi-point inspection with every Honda service. If you have an issue with your catalytic converter and don't get it revamped, your 2012 Honda Accord 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 different problems from overheating.
  • The battery is scanty or dead. The battery in your 2012 Honda Accord is every authentic. 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 surely require maintenance. The price of a new one depends on the type of Honda you drive, but check our current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Honda Accord is what determines how much fuel is needed to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to aware changes, like altitude. If your Honda Accord 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 detrimental mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or different item can wreak havoc on your 2012 Honda Accord if it’s not installed accurately. 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 familiar, bring your Accord to Honda and have our team of certified technicians ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, notably 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 2012 Honda Accord has a vacuum leak. Every Honda Accord has a vacuum system that performs a big variety of functions. The vacuum system also helps lower detrimental 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, notably if they’re exposed to imposing heat or extreme bitter.
