Before you jump into clearing the light, it’s important to understand why it turned on in the first place. The check engine light, also known as the malfunction indicator lamp (MIL), is part of your vehicle’s onboard diagnostics system (OBD2). It monitors everything from engine performance to emissions control.
Common reasons the light appears on a Dodge Journey include:
- Loose or faulty gas cap: This is one of the most frequent causes. A loose cap allows fuel vapors to escape, triggering the light.
- Oxygen sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A bad sensor reduces fuel efficiency and increases emissions.
- Catalytic converter issues: Over time, the converter can clog or fail, leading to reduced performance and higher emissions.
- Spark plug or ignition coil problems: Misfires can cause rough idling, poor acceleration, and trigger the light.
- Mass airflow (MAF) sensor dirt or damage: This sensor measures incoming air to optimize fuel delivery. Dirt or damage throws off the air-fuel ratio.
- Evaporative emissions (EVAP) system leaks: Small leaks in the fuel vapor system can set off the light even if they’re hard to detect.
In 2026, modern Dodge Journey models are equipped with advanced diagnostics that can detect even minor irregularities. That means the light might come on for something as simple as a loose gas cap—or as serious as a failing catalytic converter.
The key takeaway? Don’t ignore the light. Even if your car seems to be running fine, underlying issues could worsen over time. Clearing the light without fixing the problem is like turning off a smoke alarm while the house is still on fire.
Tools You’ll Need to Clear the Check Engine Light
To clear the check engine light on your Dodge Journey, you’ll need a few basic tools. The good news? Most are affordable and easy to find.
OBD2 Scanner (Recommended)
An OBD2 scanner is the most effective and reliable tool for clearing the check engine light. These devices plug into your vehicle’s OBD2 port—usually located under the dashboard near the steering wheel—and communicate with the car’s computer.
In 2026, OBD2 scanners range from simple code readers (under $30) to advanced diagnostic tools ($100+) that provide live data, freeze frame info, and even repair suggestions. For most Dodge Journey owners, a mid-range scanner like the BlueDriver or Ancel AD310 offers the best balance of features and price.
Basic Hand Tools
If you plan to disconnect the battery (a common reset method), you’ll need:
- A wrench or socket set (usually 10mm)
- Safety gloves and glasses
- A clean cloth or towel
Smartphone with OBD2 App (Optional)
Many modern scanners connect to your smartphone via Bluetooth. Apps like Torque Pro (Android) or OBD Fusion (iOS) let you view real-time data, log trips, and clear codes—all from your phone.
Replacement Parts (If Needed)
Depending on the trouble code, you may need to replace parts like the gas cap, oxygen sensor, or air filter. Keep these on hand if you’ve already diagnosed the issue.
Step-by-Step: How to Clear the Check Engine Light Using an OBD2 Scanner
Using an OBD2 scanner is the fastest, safest, and most accurate way to clear the check engine light on your Dodge Journey. Here’s how to do it in six simple steps.
Step 1: Locate the OBD2 Port
The OBD2 port is a 16-pin connector usually found under the dashboard on the driver’s side. In most Dodge Journey models, it’s near the steering column, just below the knee panel. You may need to crouch down or use a flashlight to see it clearly.
Tip: If you can’t find it, consult your owner’s manual or search online for “Dodge Journey OBD2 port location 2026.”
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s fully seated—loose connections can cause errors.
Step 3: Turn the Ignition to “On” (Do Not Start the Engine)
Turn the key to the “ON” position (or press the start button without pressing the brake). This powers up the vehicle’s computer without starting the engine. The scanner should light up and begin communicating with the car.
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to retrieve diagnostic trouble codes (DTCs). These codes—like P0455 (large EVAP leak) or P0171 (system too lean)—tell you exactly what’s wrong.
Write down the codes or take a photo. This info is crucial for diagnosing the issue.
Step 5: Clear the Codes
Once you’ve read the codes, look for an option like “Clear Codes,” “Erase DTCs,” or “Reset MIL.” Select it, and the scanner will send a command to turn off the check engine light.
The light should go out immediately. If it doesn’t, double-check the connection and try again.
Step 6: Verify the Reset
Start the engine and let it idle for a few minutes. If the light stays off, the reset was successful. If it returns, the underlying problem hasn’t been fixed—and the computer is still detecting an issue.
Alternative Method: Clearing the Light by Disconnecting the Battery
If you don’t have an OBD2 scanner, you can try clearing the check engine light by disconnecting the battery. This method resets the vehicle’s computer by cutting power, but it’s not as reliable—and it may not work on all 2026 Dodge Journey models.
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is completely off. Remove the key or press the start button to turn off the ignition.
Step 2: Locate the Battery
Open the hood and find the battery. In most Dodge Journey models, it’s on the driver’s side, near the front of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery post so it doesn’t accidentally reconnect.
Safety Tip: Always disconnect the negative terminal first to avoid short circuits.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer to fully reset. Some experts recommend up to 30 minutes for older systems.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is tight to prevent electrical issues.
Step 6: Start the Engine
Turn the ignition on and start the engine. The check engine light should be off—at least temporarily.
Note: This method may also reset other systems, including radio presets, clock, and adaptive transmission settings. You may need to reprogram these after reconnecting.
Using the Dodge Journey’s Built-In Reset Procedure (If Available)
Some Dodge vehicles have a built-in method to reset the check engine light using the dashboard controls. While not all 2026 Journey models support this, it’s worth checking.
Step 1: Turn the Ignition to “On”
Turn the key to the “ON” position without starting the engine.
Step 2: Press the Gas Pedal
Press the accelerator pedal all the way down and hold it for 3–5 seconds. Release it.
Step 3: Repeat the Process
Repeat this process two more times (three total), waiting about 5 seconds between each press.
Step 4: Turn the Ignition Off and On
Turn the ignition off, wait 10 seconds, then turn it back on. If the procedure worked, the check engine light should be off.
Note: This method is not officially documented for all Dodge Journey models and may not work on 2026 versions. Use it as a last resort.
What to Do After Clearing the Light
Clearing the check engine light is only half the battle. To ensure it doesn’t come back, follow these post-reset steps.
Complete a Drive Cycle
A drive cycle is a series of driving conditions that allow the vehicle’s computer to recheck all systems. This is essential for emissions testing and ensuring the problem is truly fixed.
A typical drive cycle for a Dodge Journey includes:
- Cold start: Let the engine reach operating temperature.
- City driving: Drive at varying speeds (25–45 mph) with stops and starts.
- Highway driving: Maintain 55–65 mph for 10–15 minutes.
- Deceleration: Slow down without braking aggressively.
- Idle: Let the engine idle for 2–3 minutes.
Complete this cycle once or twice after clearing the light. If the light stays off, the system has likely passed its self-tests.
Monitor the Light
Keep an eye on the dashboard. If the light returns within a few days, the issue wasn’t resolved. Recheck the trouble codes and address the root cause.
Perform Regular Maintenance
Prevention is key. Follow your Dodge Journey’s maintenance schedule, including:
- Oil changes every 5,000–7,500 miles
- Air filter replacement every 15,000–30,000 miles
- Spark plug inspection/replacement every 30,000–100,000 miles
- Fuel system cleaning every 30,000 miles
- Tire rotation and alignment checks
Regular care reduces the chances of future check engine light issues.
Troubleshooting: When the Light Keeps Coming Back
If you’ve cleared the check engine light but it keeps returning, don’t give up. Here’s how to troubleshoot persistent issues.
Recheck the Trouble Codes
Use your OBD2 scanner to read the codes again. Are they the same? Different? New codes can indicate a worsening problem or a secondary issue.
Inspect Common Culprits
Go back to the basics:
- Is the gas cap tight and undamaged?
- Are there visible leaks under the hood?
- Does the engine run rough or hesitate?
- Is there a burning smell or unusual noise?
Sometimes, a simple fix like tightening the gas cap or replacing a cracked vacuum hose solves the problem.
Check for Software Updates
In 2026, many vehicles receive over-the-air (OTA) updates. Check with your Dodge dealer to see if a software update is available for your Journey. These updates can fix bugs in the engine control module (ECM) that trigger false warnings.
Visit a Professional Mechanic
If you’ve tried everything and the light keeps coming back, it’s time to see a certified technician. They have advanced tools and expertise to diagnose complex issues like internal engine problems, transmission faults, or electrical gremlins.
Don’t ignore persistent warnings—they could signal serious damage if left unchecked.
