What are the common reasons for an RV check engine light?

The are many common reasons for an RV check engine light to turn on. It might be for the simplest reason that can be resolved in just a few minutes. However, if you still find the check engine light on for a long time, make sure to take your vehicle to an expert. Here are some of the reasons for an RV check engine light to turn on.

Damaged gas cap

• The most common reason for the RV check engine light to blink is a faulty or loose gas cap. This can also happen in cars and there is nothing to worry about it. 
• A common mistake is when people forget to tighten the gas cap. 
• The first thing to do is check if there is a gas cap fixed correctly. You can pull over and find this out on your own.
• Some gas caps can be faulty and the RV check engine light will mostly come up only when you hit the road. 
• Be sure to look for any damage to the gas cap. Some caps might be broken or have a small crack. 
• Remove the gas cap and put it back again and continue driving. There are chances for the RV check engine light to turn off. 
• You can also purchase a new cap and fix it.

Oxygen Sensor

• The second and most common reason is a damaged oxygen sensor. If the oxygen sensor is damaged, the RV check engine light will start to blink. 
• Replacing the oxygen sensor will help in this case. 
• It is also advised to replace these oxygen sensors since they can cause damage to the catalytic converter. However, you will have a little time to finish your trip and get to a mechanic.

Damaged spark plug

• Another issue can be due to a damaged spark plug. 
• Remember, that a spark plug has a lifespan and it should be replaced after 30,000 miles.
• The latest sparkplugs last longer and are built to last up to 100,000 miles. 
• A faulty sparkplug will cause the engine to misfire. 
• Your engine will struggle to start and thus the RV check engine light kicks in.

Faulty catalytic converter

A faulty catalytic converter will stop producing or converting carbon monoxide. This can be dangerous for the environment and it must be fixed soon. While you might be able to drive for some more time, it is advised to get this changed soon. Catalytic converters are required to be changed every couple of years.

Faulty mass airflow sensor

• The airflow sensor is another important part that needs to be checked. The airflow sensor is what determines the amount of fuel that is required for the RV. 
• A damaged air flow sensor will increase the emission in the vehicle and it can lead the RV to stall. 
• Air filters need to be replaced every couple of years since they are prone to dust and particles.

Additional causes for an RV check engine light

A few other causes might contribute to the RV check engine light. These might be very simple issues, but they do have an impact on the vehicle. Be sure to check if there is condensation under the hood of the RV. The tire pressure is also important but all these problems together can cause the check engine light to activate.

Engine and transmission problems

A problem with the engine and transmission can also cause the RV check engine light to blink. The transmission of the car manipulates the power of the engine and a problem with the transmission can also get the light turned on. The control module will sometimes detect an issue with the transmission and will turn on the check engine light.

One way to get rid of the check engine light is to restart the RV. If the above conditions are found in your RV, you can still drive your vehicle around for a week or two. But it is advised not to go on long distances and get it checked as soon as you can. Resolving these issues can be done in a jiffy and they are also not too expensive.

Low engine oil

Low engine oil is not going to indicate the check engine light. Most people have a misconception that a turned-on check engine light means low engine oil. That is not the case in this situation. The check engine light can indicate various reasons and low engine oil is certainly not one of them. If your vehicle is low on engine oil, the oil light on the dashboard will turn on.

The most common issue for the check engine light to turn on is mentioned above. In some cases, it might be a serious engine condition that needs immediate attention. Irrespective of the reason, the best thing is to get this issue sorted out soon. Only an experienced mechanic will be able to determine the causes of the check engine light on your RV.

Other reasons 

Most of the reasons will include ignition systems problems, air or fuel delivery problems, modules, and sensors, emissions equipment problems, and engine and transmission problems. Apart from those, they might be other minute issues. That said, there is no need to panic or worry if you find your RV check engine light turned on or blinking.

The RV check engine light is like a warning signal. It can be due to something simple and harmless. At the same time, it can be related to something serious that can damage your other components. The best way is to get this checked and avoid such issues in the future. However, you will still have some time to get your vehicle to an expert.

The check engine light will turn on if there is too much engine strain. This is a common indication as the check engine light is built to give you a warning. It happens mostly when the RV is towing something and there is too much strain on the engine. In this case, the RV engine will drop in terms of power.

You will be able to feel the engine providing less power. If you come across the RV check engine light, you must stop at the nearest mechanic to get these issues checked. Excessive engine strain is not good for your RV and it can lead to further complications. It can also be due to overheating or an oil pressure failure.

Immediate solutions for an RV check engine light

The best and immediate solution is to seek assistance. In some cases, you might be on the highway and your RV check engine light might come on. In that case, the best solution will be to reduce the speed of your vehicle or try to remove the load if possible and see if the situation resolves. However, it is best to get in touch with an expert or pull over and call for help.

This can be stressful and confusing if you don’t know what to do. The first and most important thing is not to panic. There is nothing that you can do to determine the cause unless you are a mechanic yourself. There are reasons why the RV check engine light turns on. Understanding those reasons can help you be aware of this situation.
