Understanding the Check Engine Light
Before you rush to reset the engine light, it’s important to understand what it actually means. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). When the car’s computer detects a problem with the engine, emissions system, or other critical components, it triggers the light to alert you.
But here’s the thing: the light doesn’t tell you *what* is wrong—only that *something* is. It could be as simple as a loose gas cap or as serious as a failing catalytic converter. That’s why diagnosing the issue is the first and most important step.
Common reasons the check engine light comes on in a 2014 Dodge Dart include:
– Loose or faulty gas cap
– Oxygen (O2) sensor failure
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Catalytic converter inefficiency
– Exhaust gas recirculation (EGR) valve malfunction
– Evaporative emissions system leaks
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. So while resetting the light might make it go away temporarily, it won’t fix the problem—and the light will likely return.
Tools You’ll Need
Before you begin, make sure you have the right tools on hand. Most of these are affordable and easy to find online or at auto parts stores.
OBD2 Scanner
This is the most reliable tool for diagnosing and resetting the engine light. A basic OBD2 scanner plugs into your car’s diagnostic port and reads trouble codes. Many models also allow you to clear codes and reset the light. Look for one that’s compatible with your 2014 Dodge Dart—most universal scanners work fine.

Basic Hand Tools (Optional)
If you plan to inspect or replace components like the gas cap or air filter, you might need a screwdriver, socket wrench, or pliers. But for a simple reset, these aren’t necessary.
Owner’s Manual
Your Dodge Dart’s owner’s manual contains useful information about the dashboard warning lights, fuse box location, and maintenance schedules. Keep it handy for reference.
Safety Gear
While resetting the engine light isn’t dangerous, it’s always smart to wear gloves and safety glasses—especially if you’re working near the battery or under the hood.
Step 1: Diagnose the Problem
You can’t reset the engine light effectively without knowing why it’s on. Skipping this step is like turning off a fire alarm without putting out the fire—it might seem like the problem is solved, but it’s still there.
Locate the OBD2 Port
In the 2014 Dodge Dart, the OBD2 port is located under the dashboard on the driver’s side. It’s usually near the steering column, just above the pedals. It’s a 16-pin connector that looks like a trapezoid. You don’t need any tools to access it—just reach under the dash and look for the port.
Plug in the OBD2 Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s fully seated. Then, turn the ignition to the “ON” position (but don’t start the engine). The scanner should power up and display a menu.
Read the Trouble Codes
Follow the scanner’s instructions to retrieve the diagnostic trouble codes (DTCs). These codes—like P0457 (loose gas cap) or P0171 (system too lean)—tell you what system is malfunctioning. Write them down or take a photo for reference.
Interpret the Codes
Use the scanner’s built-in code library or search online for the meaning of each code. For example, P0300 indicates a random/multiple cylinder misfire, while P0420 suggests a catalytic converter issue. Understanding the code helps you decide whether you can fix it yourself or need professional help.
Step 2: Fix the Underlying Issue
Now that you know what’s causing the engine light, it’s time to fix it. Here are some common fixes for the 2014 Dodge Dart:
Tighten or Replace the Gas Cap
A loose or damaged gas cap is one of the most common causes of the check engine light. Simply tighten it until it clicks, or replace it if it’s cracked or worn. After driving a few miles, the light may turn off on its own—but if not, you’ll need to reset it.
Replace Faulty Sensors
If the code points to an O2 sensor or MAF sensor, you may need to replace it. These parts are relatively easy to access on the Dart. For example, the MAF sensor is located in the air intake tube between the air filter and throttle body. Disconnect the electrical connector, remove the sensor, and install the new one.
Address Ignition System Problems
Codes related to misfires (like P0301–P0304) often stem from bad spark plugs or ignition coils. The 2014 Dart uses coil-on-plug ignition, so each cylinder has its own coil. Replacing these components requires removing the engine cover and accessing the coils. If you’re not comfortable doing this, consider visiting a mechanic.
Check the Emissions System
Evaporative emissions leaks (P0440–P0457) can be tricky. They might involve cracked hoses, a faulty purge valve, or a leaking charcoal canister. Use a smoke machine or have a professional perform a smoke test to locate the leak.
Step 3: Reset the Engine Light Using an OBD2 Scanner
Once the issue is fixed, it’s time to reset the engine light. The safest and most effective way is using your OBD2 scanner.
Reconnect the Scanner
Plug the scanner back into the OBD2 port and turn the ignition to “ON.” Make sure the engine is off.
Navigate to the Clear Codes Menu
Use the scanner’s buttons to find the option to “Clear Codes” or “Reset MIL.” This may be under a menu like “Diagnostics” or “Tools.”
Confirm the Reset
The scanner will ask if you’re sure you want to clear the codes. Select “Yes” or “Confirm.” The scanner will send a signal to the car’s computer to turn off the check engine light.
Verify the Reset
After clearing the codes, the light should go off immediately. If it doesn’t, try turning the ignition off and on again. You can also use the scanner to check if any codes remain. If the light stays off, the reset was successful.
Alternative Method: Reset by Disconnecting the Battery
If you don’t have an OBD2 scanner, you can reset the engine light by disconnecting the battery. This method forces the car’s computer to reset, clearing stored codes and turning off the light. However, it comes with some downsides.
Turn Off the Ignition
Make sure the car is off and the keys are out of the ignition.
Locate the Battery
The battery in the 2014 Dodge Dart is under the hood on the driver’s side. It’s held in place by a bracket and connected with positive and negative terminals.
Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and set it aside so it doesn’t touch the terminal.
Wait 10–15 Minutes
This gives the car’s computer time to fully discharge and reset. Some people recommend waiting up to 30 minutes for a complete reset.
Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is snug to avoid electrical issues.
Start the Car
Turn the ignition on and start the engine. The check engine light should be off. If it comes back on, the problem wasn’t fixed—or the reset didn’t take.
Be Aware of Side Effects
Disconnecting the battery can reset other systems, including:
– Radio presets and clock settings
– Adaptive transmission learning (may cause rough shifting at first)
– Anti-theft system (may require re-syncing)
– Power window and sunroof calibration
These issues are usually minor and can be fixed by driving the car for a few miles or manually resetting the radio.
Troubleshooting: What If the Light Comes Back On?
Even after resetting the light, it may return. This means the underlying problem wasn’t fully resolved. Here’s what to do:
Re-scan for Codes
Use your OBD2 scanner to check for new or recurring trouble codes. Compare them to the original codes to see if the issue persists.
Inspect Recent Repairs
Did you replace a sensor or part? Make sure it was installed correctly and is functioning. A poorly seated O2 sensor or loose electrical connector can cause the light to return.
Check for Intermittent Issues
Some problems, like a failing ignition coil or intermittent vacuum leak, don’t trigger the light every time. They may only appear under certain conditions (e.g., cold starts or high engine load).
Clear Codes and Drive
After fixing the issue, clear the codes again and drive the car normally for several days. The car’s computer runs self-tests during this time. If the light stays off, the problem is likely resolved.
Seek Professional Diagnosis
If the light keeps coming back or you’re unsure about the diagnosis, visit a trusted mechanic or Dodge dealership. They have advanced tools and expertise to pinpoint complex issues.
Preventing Future Engine Light Issues
The best way to avoid dealing with the check engine light is to maintain your 2014 Dodge Dart properly. Here are some tips:
