Check Engine Light Service 2012 RAM 2500

What do you do when you’re driving along in your RAM 2500 and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most RAM owners, your heart sinks extremely because you may have explicitly idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep, peaceful breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is advised that you get your 2012 RAM 2500 checked promptly. Ignoring that warning could end up causing major, considerable damage to costly engine components.

When your 2012 RAM 2500's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is usually 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 can expeditiously identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our RAM auto repair mechanics at Larry H. Miller Dodge RAM FIAT Tucson. There are again a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you pick that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the explicitly correct issue and repair it.

What could cause the check engine light to come on in a 2012 RAM 2500?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Still, the check engine light could likewise be a warning of a meaningful problem that could cause serious damage to your engine and come with a hefty and expensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow ordinarily means something less serious but a flashing check engine light indicates that your vehicle’s engine is in significant trouble and useful service is necessary promptly. If your check engine light is flashing in your 2012 RAM 2500, we immensely advocate not to drive the car and schedule RAM service today. Below is a list of the most common reasons your check engine light can come on:

  • Your 2012 RAM 2500 has a vacuum leak. Each RAM 2500 has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower unhealthy 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 RAM 2500’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is normally caused by consistently neglected maintenance, which is why Larry H. Miller Dodge RAM FIAT Tucson offers a free multi-point examination with each RAM service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 RAM 2500 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
  • The battery is low or dead. The battery in your 2012 RAM 2500 is each essential. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of RAM 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 RAM 2500 is what determines how much fuel is required 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 certain changes, like altitude. If your RAM 2500 is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a damaged mass airflow sensor.
  • New Spark Plugs or Plug Wires are required for your 2012 RAM 2500. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run smooth. 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 old, you will experience a noticeable 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, leading to more pricey repairs.
  • One of the most common and frequent cause is that your 2012 RAM 2500 gas cap is loose, broken or missing. The gas cap for your 2012 RAM 2500 serves different purposes. It prevents dangerous 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 damaged fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more expensive. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on promptly after you put gas in your 2012 RAM 2500, 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 O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more expeditiously and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A damaged sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2012 RAM 2500's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct combination of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can again cause a vehicle to fail an emissions test.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2012 RAM 2500 if it’s not installed properly. These aftermarket components 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 2500 to RAM and have our team of skilled certified mechanics assure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
