Why does my Dodge Check Engine Light come on? There are many things that can go wrong with your car and cause the check engine light to come on. Follow the steps below to figure out what’s wrong and how to fix it.
If your Dodge’s Check Engine Light (CEL) stays on when you start the car or comes on while you’re driving, it means that the On-Board Diagnostics (OBD) system has found a problem.
Dodge Check Engine Light
A flashing light means that the problem is very serious and that if it isn’t fixed quickly, it could cause major damage to the car. If the check engine light on your Dodge starts flashing, it means that something is wrong and needs to be fixed right away. Bring your Dodge in right away.
This blinking light usually means that the engine has a serious misfire, which lets unburned fuel go into the exhaust system. There, it can instantly raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive and major repair.
Some owners ask if the check engine light flashes because of the spark plugs. This could be the exact reason. Misfiring can happen when a spark plug is broken, old, or dirty.
If you don’t fix the problem or keep driving, it could spread to the spark plug wires, catalytic converter, or ignition coils, which would be a very expensive fix.
Is it safe to drive with the check engine light on in my Dodge?
If your Dodge’s check engine light is flashing, it means there is a serious problem that needs to be fixed right away. This is not an easy question to answer because it depends on how bad the problem is. If the problem is small, like a loose gas cap, the car should be safe to drive.
Most of the time, this is shown by the check engine light that stays on. If you notice a change in how the car runs, it could mean that there is a more serious problem. Call 2085100490 to talk to the experts at Larry H. Miller Chrysler Jeep Dodge Ram Boise about the problems. Or, slow down and get your Dodge to our trained mechanics as soon as you can.
How far can you go when the check engine light is on?
The safest thing to do is figure out what the code means and then plan your strategy based on that. Since each check engine code has a different level of seriousness, it’s hard to know how many miles you can drive safely with the warning light on.
It could be a bad sensor or that the plug wires need to be changed. If your check engine light is flashing, you should pull over and call Larry H. Miller Chrysler Jeep Dodge Ram Boise. They can help you figure out if your car is safe to drive or if you should call a tow truck.
What Does the Light That Says “Check Engine” Mean?
The check engine light on your Dodge is one of the most commonly misunderstood lights or indicators. The check engine light is an important part of the onboard diagnostics system. It can show up in a number of ways. It could say “Check Engine,” it could be a picture of an engine, or it could be both.
This light can be either yellow or red, and it is part of the diagnostics system in your car. Since the 1980s, onboard computers have been controlling and monitoring car performance more and more. They can do many things for your Dodge. Some of these important jobs include controlling the speed of the engine, shifting automatic transmissions, adjusting the timing of the ignition, and putting in place cohesion control, just to name a few.
So, the check engine light can mean a number of different things. It could be as simple as a loose gas cap or as dangerous as an engine knock.
There are a lot of things that could cause the Check Engine Light to come on, but after years of providing Check Engine Light Diagnosis Service, we know that there are a few common ones, like a loose gas cap.
A Check Engine Light can also be caused by a dirty mass airflow sensor, a bad emissions control part, a problem with the fuel injection system, a broken oxygen sensor, a bad head gasket, or bad spark plugs, to name a few. No matter what is causing the Check Engine Light to come on, we have the Dodge Certified Mechanics and the certified service protocol to find the source of the problem and fix it as needed to bring it back to factory standards.
When this happens, the Check Engine Light will turn off, and you’ll know that the problem with your Dodge is completely fixed.
Every Dodge was made with a high-tech performance monitoring system that includes a computer and a number of sensors placed in key places around the car to track its most important systems.
The fast sensors are always figuring out what’s going on and sending important information to the electronic control unit. If the electronic control unit sees that the data is not within factory limits, the Check Engine Light will come on to let you know there is a problem.
But the Check Engine Light can’t tell you what’s wrong or what to do about it. That’s where we come in. Larry H. Miller Chrysler Jeep Dodge Ram Boise offers a Check Engine Light Diagnosis Service that finds the root of the problem and gives you advice on what to do next from an Extremely Qualified Service professional.
How much does it cost to have someone check the engine light?
The average cost to diagnose and test a check engine light is between $88 and $111. The good news is that Larry H. Miller Chrysler Jeep Dodge Ram Boise offers free multi-point inspections and, in most cases, free diagnostics to help you figure out why your check engine light is on.
The check engine light can be a sign of problems as small as a loose gas cap or as big as a bad catalytic converter or a problem with one of the car’s oxygen sensors, so it’s important to read the codes and figure out what’s wrong.
Will the check engine light reset itself?
If the problem or code that made your Dodge’s check engine light come on is fixed, the light should turn off by itself. For example, if your check engine light came on because your gas cap was loose, tightening it will turn the light off right away. Also, if your catalytic converter is working well and you did a lot of stop-and-go driving, the check engine light may have come on because the converter was used so much. Most of the time, your Dodge light will turn off between 20 and 40 miles later. If you drive over that amount and the light is still on, you will need to bring it to Larry H. Miller Chrysler Jeep Dodge Ram Boise so the light and code can be checked again and reset.
Dodge Service Check Engine Light
What do you do when you’re driving your Dodge and all of a sudden a yellow light that says “Check Engine” comes on? If you’re like most Dodge owners, your heart sinks because you may not know what that light means or what to do. Just as stressful can be the fear of the unknown or the cost of the unknown.
But take a deep breath and know that when the light comes on, you don’t have to pull over to the side of the road and call a tow truck. Instead, you should get your Dodge checked as soon as possible. If you don’t pay attention to that warning, expensive engine parts could get severely damaged.
When your Dodge’s onboard computer, the electronic control module (ECM), finds a problem in the electronic control system that it can’t fix, a computer turns on your check engine light. This amber or yellow light usually says “Check engine” or “Service engine soon.” Sometimes, the light is just a picture of an engine or the word “check” next to a picture of the engine.
When the light comes on, the engine control module (ECM) stores a “trouble code” or “engine code” in its memory. This code lets you know right away what’s wrong, whether it’s a sensor or a broken engine part.
If you want to do it yourself, there are also a number of code readers that are not too expensive and are made for that. Even though this code will tell you what problem was found, a real diagnosis still needs a trained professional to find the exact problem and fix it.
Dodge Check Engine Light Codes
The check engine light coming on can be scary, especially when that little light on your car’s dashboard suddenly lights up, but you shouldn’t shut down in fear right away. If you hear the term “diagnostic trouble codes” (DTC), it just means “check engine light codes.”
These are computer codes for cars that are stored by the ECM, which is also called the OBD (on-board computer diagnostic system) in your vehicle. There are a lot of different codes that your car’s check engine light can show. Even though that sounds hard, if you take the time to do basic diagnostics, you’ll learn useful things about your car and once again be able to use the Check Engine Light as it was meant to be used: as a guide.
Unfortunately, the Check Engine Light does not always come on with clear and helpful signs that something is wrong with the car. Since there are a lot of possible OBD codes, there are also a lot of possible reasons why the light is on.
- Bad Spark Plugs
- Fuel and air metering systems problems
- Transmission issues
- Computer output circuit issues
- Problems with the old battery ignition system
- Emissions controls issues
- O2 Sensor Gas Cap Loose or Missing
Some Reasons why Your Dodge Check Engine Light Stays On ?
If your car’s check engine light comes on, you might just need to tighten or replace the gas cap. Still, the check engine light could be a sign of a serious problem that could damage your engine and cost a lot to fix. Depending on what kind of car you have, the check engine light will either be on or blink.
A steady glow is usually a sign of something less serious, but a blinking check engine light means that your car’s engine is in serious trouble and needs help right away. If your Dodge’s check engine light is flashing, you should not drive it and should get Dodge service as soon as possible. Here are the most common reasons why your check engine light might turn on:
The gas cap on your Dodge is loose, broken, or gone.
The gas cap on your Dodge has more than one job to do. It keeps dangerous gas fumes from escaping when you’re not driving. It also seals the fuel system and keeps the pressure in the fuel tank steady. What happens if your fuel cap is broken? If your gas cap is old or the seal has been broken, you could lose gas through evaporation.
This means you’ll have to go to the pump more often and spend more money. Luckily, it doesn’t cost much to replace a gas cap. If your Dodge’s check engine light comes on quickly after you put gas in it, you should first make sure the gas cap isn’t loose or that it’s still on the roof or at the fuel pump.
any problems with aftermarket items.
If you don’t put in an aftermarket alarm, exhaust, or other part correctly, it can do a lot of damage to your Dodge. These aftermarket parts and accessories can drain the battery, turn on the check engine light, or even stop the car from starting. If these problems sound familiar, bring your car to Dodge and let our team of experienced, certified mechanics make sure your aftermarket parts were installed correctly and aren’t causing any problems.
Getting accessories, especially aftermarket parts and accessories, or using OEM parts from the start might cost a bit more, but it could save you a lot of money in the long run if you don’t have to fix bad work or damage caused by bad installation.
Your MAF, which stands for mass airflow sensor, needs to be changed
The mass airflow sensor in your Dodge measures how much air is going into the engine to figure out how much fuel it needs to run efficiently. The mass airflow sensor is a part of the engine management system. It helps the engine adjust to changes like altitude.
If your Dodge is hard to start, has a rough idle, or the throttle pedal moves quickly and suddenly, this could be a major sign that the mass airflow sensor is broken.
Your Dodge has a vacuum leak.
Every Dodge has a vacuum system that does a lot of different things. As gasoline evaporates, fumes are sent through the engine by the vacuum system. This helps cut down on harmful emissions.
If your RPM is high at idle or goes up and down randomly, it could be because of a vacuum leak. Vacuum hoses can dry out and crack over time, especially if they are exposed to very hot or very cold temperatures.
You need to get a new O2 Sensor (Oxygen Sensor)
The Oxygen sensor, also called the O2 sensor, checks how much oxygen is in your exhaust system. If there is too much oxygen in your exhaust system, your fuel will burn more quickly, and your car will use more gas.
If I don’t replace your O2 sensor, what will happen? A broken sensor can not only change how many miles per gallon your car gets, but it can also damage your Dodge’s catalytic converter and spark plugs in a big way.
The O2 sensor sends information to the car’s onboard computer so that the right amount of air and fuel can be put into the engine’s cylinders. A vehicle can also fail an emissions test if its O2 sensor is broken.
Your catalytic converter is broken or is about to break.
The catalytic converter is part of the exhaust system of your Dodge. The job of the catalytic converter is to change the carbon monoxide that is made during combustion into carbon dioxide. A broken catalytic converter is often caused by poor maintenance, which is why Larry H. Miller Chrysler Jeep Dodge Ram Boise gives every Dodge service a free multi-point inspection.
If your catalytic converter is broken and you don’t get it fixed, your Dodge won’t pass an emissions test, the engine won’t run as well, and your gas mileage will go down. Your car may also run at a higher temperature, which can lead to other problems if it gets too hot.
The battery is dead or almost dead
Your Dodge’s battery is a very important part. Without a battery, your car won’t start, it won’t light up the road in front of you, it won’t play the radio, and it won’t charge your phone. Batteries for cars today last a lot longer than they did a few decades ago, and they don’t really need to be taken care of.
The price of a new one depends on what kind of Dodge you drive, but check out our current service coupons and specials.
Your Dodge needs new spark plugs and/or plug wires
The spark plugs are the part of your car’s engine that lights the mixture of air and fuel in your car’s combustion chamber. This explosion is what moves the pistons and makes the engine run smoothly. The ignition coil sends the spark to the spark plugs through the spark plug wires.
If your spark plugs or spark plug wires are broken or old, your car will run much less well and have less power. In the worst cases, your engine won’t start or will have trouble running. If the spark plugs and plug wires are worn, the catalytic converter can get clogged or the ignition coils and O2 sensors can get damaged, which will cost more to fix.
