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, again known as the OBD (on-board computer diagnostic system) in your.

Will the check engine light reset itself?

The check engine light on your Jeep will frequently shut itself off if the issue or code that caused it to turn on is fixed. For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will immediately turn itself off. Still, if your catalytic converter is working accurately, 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 Jeep 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 Larry H. Miller Chrysler Jeep Dodge RAM Surprise so the light and code can be double-checked and reset.

If the check engine light in your Jeep starts flashing, that means that the problem needs attention immediately and your Jeep should be brought in promptly. A flashing light reveals that the problem is very serious and if not taken care of immediately may result in major and significant damage to the car. This blinking light usually reveals a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can expeditiously raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive and huge repair. Some owners ask if spark plugs cause the check engine light to flash? This can explicitly be the cause. A damaged, old or dirty spark plug can cause the engine to misfire. If the problem is completely ignored or you continue to drive, this can spread to the spark plug wires, catalytic converter, or ignition coils which can lead to a exceptionally pricey repair.

Check Engine Light Service Jeep

What do you do when you’re driving along in your Jeep and suddenly, a yellow light illuminates on your dash and says "Check Engine".

Ignoring that warning could end up causing major, considerable damage to costly engine components.

When your Jeep '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 ordinarily 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 instantly 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 Jeep auto repair mechanics at Larry H. Miller Chrysler Jeep Dodge RAM Surprise. There are also a number of comparatively inexpensive code readers that are designed for do-it-yourselfers, should you choose 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 definitely correct issue and repair it.

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

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Also, the check engine light could still 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 generally means something less serious but a flashing check engine light reveals that your vehicle’s engine is in significant trouble and helpful service is needed instantly. If your check engine light is flashing in your Jeep, we very endorse not to drive the vehicle and schedule Jeep service today. Below is a list of the most common reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Jeep if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your to Jeep and have our team of accomplished certified mechanics assure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.
  • 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 immediately and your car 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 Jeep 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the precisely correct combination of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can also cause a car to fail an emissions test.
  • Your Jeep has a vacuum leak. Every Jeep 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 dry out and crack, particularly 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 Jeep ’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 regularly neglected maintenance, which is why Larry H. Miller Chrysler Jeep Dodge RAM Surprise offers a free multi-point examination with every Jeep service. If you have an issue with your catalytic converter and don't get it repaired, your Jeep 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 other perilous problems from overheating.
  • One of the most common and frequent cause is that your Jeep gas cap is loose, damaged or missing. The gas cap for your Jeep serves various purposes. It prevents unpredictable 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 costly. If your check engine light turns on rapidly after you put gas in your Jeep, 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.
  • The battery is low or dead. The battery in your Jeep is every critical. 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 genuinely require maintenance. The price of a new one depends on the type of Jeep you drive, but check our current service coupons and specials.
  • New Spark Plugs or Plug Wires are necessary for your Jeep. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your car. 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 costly repairs.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Jeep is what determines how much fuel is necessary 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 Jeep is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a essential sign of a damaged mass airflow sensor.

How much does it cost to get the engine light checked?

The check engine light warns of issues ranging from a gas cap that's not correctly tightened to a more serious failure like a bad catalytic converter or a problem with one of the car's oxygen sensors, so it good to get the proper code reading and diagnosis.
