Common Causes Of Check Engine Light
If you own a 2019 Ram, chances are you’ve experienced the frustration of the check engine light coming on. This warning light can indicate a range of issues, from minor to more serious. Understanding the common causes of the check engine light can help you determine the next steps to take in resolving the problem.
Faulty Oxygen Sensor
A faulty oxygen sensor is one of the most common reasons for the check engine light to come on in your 2019 Ram. This sensor is responsible for measuring the amount of unburned oxygen in the exhaust system. When it fails, it can lead to decreased fuel efficiency and increased emissions.
Faulty Emissions Control Part
If your check engine light is illuminated, it could be due to a faulty emissions control part. This can include components such as the catalytic converter, EGR valve, or EVAP system. These parts are designed to reduce harmful emissions from your vehicle. When they malfunction, it can not only trigger the check engine light but also lead to increased pollution.
Dirty Mass Airflow Sensor
The mass airflow sensor (MAF) is responsible for measuring the amount of air entering the engine. When it becomes dirty or contaminated, it can provide inaccurate readings, causing the check engine light to come on. Cleaning or replacing the MAF sensor can help restore proper engine performance and improve fuel efficiency.
Defective Spark Plugs
Another common cause of the check engine light is defective spark plugs. Spark plugs play a critical role in igniting the air/fuel mixture in the combustion chamber. When they fail, it can result in misfires, reduced engine power, and increased fuel consumption. Replacing the faulty spark plugs can usually resolve this issue and turn off the check engine light.
In conclusion, the check engine light in your 2019 Ram can indicate a variety of issues. From a faulty oxygen sensor to a dirty mass airflow sensor, it’s important to address these problems promptly to avoid further damage to your vehicle and ensure optimal performance. If you are unsure of the cause, it’s always best to consult with a professional mechanic who can diagnose the issue and provide the necessary repairs.

Immediate Actions To Take
When the dreaded check engine light comes on in your 2019 Ram, it’s important to take immediate action to prevent further damage and ensure the safety and performance of your vehicle. Ignoring the check engine light can lead to costly repairs down the line. In this section, we will discuss two immediate actions you should take when faced with a check engine light: checking the fuel cap and addressing a blinking engine light.
Check Fuel Cap
One of the most common and simplest causes of a check engine light is a loose or faulty fuel cap. A loose fuel cap can cause an imbalance in the fuel system, leading to an illuminated check engine light. To address this issue:
- Turn off the engine and ensure the vehicle is in park.
- Locate the fuel cap, usually located on the driver’s side of the vehicle.
- Remove the fuel cap and inspect it for any visible signs of damage or wear.
- Wipe the cap clean with a cloth or paper towel to remove any debris.
- Ensure the cap is securely tightened by twisting it until you hear a clicking sound.
- Start the engine and check if the check engine light remains illuminated. If not, the issue may have been resolved. If the light persists, it is recommended to seek professional assistance.
Address Blinking Engine Light
If your check engine light is blinking, it is indicating a more serious issue that requires immediate attention. A blinking engine light can signify a misfire in the engine, which can potentially cause severe damage to your vehicle. It is crucial to address this issue promptly. Follow these steps:
- Safely pull over to the side of the road and turn off the engine.
- Inspect the vehicle for any visible signs of damage, such as leaking fluids or strange noises.
- Turn the engine back on and see if the blinking light persists. If it does, it is recommended to have your vehicle towed to a trusted mechanic or dealership for further inspection.
- Avoid driving the vehicle until the issue is resolved, as continued operation can lead to further damage or even a complete breakdown.
By taking immediate action and addressing these common issues, you can potentially prevent further damage to your 2019 Ram and ensure its longevity and performance on the roads. It is always recommended to consult a professional technician or dealership for a thorough diagnosis and repair of your vehicle.
