But take a deep, tranquil breath and realize the light coming on doesn't mean you have to pull the vehicle over to the side of the road and call a tow truck, but it is suggested that you get your 2023 Jeep Wrangler Unlimited checked immediately. Ignoring that warning could end up causing major, considerable damage to costly engine components.

When your 2023 Jeep Wrangler Unlimited's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can't appropriate, a computer turns on your check engine light. This amber or yellow light is generally 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 Jeep auto repair mechanics at Larry H. Miller Casa Chrysler Jeep. There are also a number of essentially 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 exactly appropriate issue and repair it.

For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will swiftly turn itself off. Likewise, if your catalytic converter is working perfectly, 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 2023 Jeep Wrangler Unlimited 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.

What could cause the check engine light to come on in a 2023 Jeep Wrangler Unlimited?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Again, the check engine light could also be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow usually means something less serious but a flashing check engine light indicates that your vehicle's engine is in serious trouble and helpful service is needed promptly. If your check engine light is flashing in your 2023 Jeep Wrangler Unlimited, we exceptionally advise not to drive the car and schedule Jeep service today. Below is a list of the most regular 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 2023 Jeep Wrangler Unlimited if it's not installed perfectly. These aftermarket parts 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 Wrangler Unlimited to Jeep and have our team of accomplished certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or using OEM parts 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.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Jeep Wrangler Unlimited 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 Jeep Wrangler Unlimited is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a vital sign of a damaged mass airflow sensor.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2023 Jeep Wrangler Unlimited'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 normally caused by constantly neglected maintenance, which is why Larry H. Miller Casa Chrysler Jeep offers a free multi-point examination with each Jeep service. If you have an issue with your catalytic converter and don't get it repaired, your 2023 Jeep Wrangler Unlimited 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 delicate problems from overheating.
• The battery is low or dead. The battery in your 2023 Jeep Wrangler Unlimited is each important. Without a vehicle battery, your vehicle won't start, light up the road in front, 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 Jeep you drive, but check our current service coupons and specials.
• New Spark Plugs or Plug Wires are required for your 2023 Jeep Wrangler Unlimited. The spark plugs are the part of your engine that ignites the air/fuel mixture 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 go through a conspicuous poor performance and decreased 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.
• One of the most common and frequent cause is that your 2023 Jeep Wrangler Unlimited gas cap is loose, damaged or missing. The gas cap for your 2023 Jeep Wrangler Unlimited serves multiple purposes. It prevents dangerous gas fumes from being released when you aren't driving, it seals the fuel system and helps manage pressure within the fuel tank. What occurs 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 immediately after you put gas in your 2023 Jeep Wrangler Unlimited, 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 instantly and your car will be less efficient when it comes to fuel economy. So what occurs 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 2023 Jeep Wrangler Unlimited's spark plugs. The O2 sensor sends data to the vehicle's onboard computer to determine the definitely correct mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can also cause a vehicle to fail an emissions test.
• Your 2023 Jeep Wrangler Unlimited has a vacuum leak. Each Jeep Wrangler Unlimited has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower adverse 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.

If you check engine light is flashing, we advocate that you pull over and contact Larry H. Miller Casa Chrysler Jeep to help determine if your car is safe to drive in or if we advocate a tow truck. It could be anything from a bad sensor to plug wires needing to be replaced. The safest bet is to decipher the code and then plan your strategy accordingly. Since each check engine code has its own level of severity, it is ordinarily difficult to predict how many miles you can be safe in driving with the warning light on.
