Before resetting the light, it’s essential to understand what might have triggered it. The check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). When the engine control unit (ECU) detects a problem with the engine, emissions, or related systems, it stores a diagnostic trouble code (DTC) and illuminates the light.
Common causes in a 2013 Dodge Journey include:
- Loose or damaged gas cap: One of the most frequent culprits. A loose cap allows fuel vapors to escape, triggering an evaporative emissions code.
- Faulty oxygen (O2) sensor: These sensors monitor exhaust gases and help regulate fuel mixture. A failing sensor can reduce fuel efficiency and increase emissions.
- Mass airflow (MAF) sensor issues: This sensor measures how much air enters the engine. Dirt or malfunction can cause poor performance and rough idling.
- Spark plug or ignition coil problems: Worn spark plugs or failing coils can cause misfires, leading to reduced power and increased emissions.
- Catalytic converter failure: Often a result of long-term neglect, a clogged converter can cause poor performance and high emissions.
- Exhaust gas recirculation (EGR) valve issues: A stuck or dirty EGR valve can cause rough idling and increased NOx emissions.
Ignoring these issues can lead to decreased fuel economy, reduced engine performance, and even damage to other components. That’s why resetting the light should always come after diagnosing and addressing the root cause.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most effective way to reset the check engine light on your 2013 Dodge Journey is by using an OBD2 scanner. This tool reads the diagnostic trouble codes stored in your vehicle’s computer, allowing you to understand what’s wrong before clearing the light.
What You’ll Need
- OBD2 scanner (basic models start around $20)
- Your 2013 Dodge Journey
- Ignition key
Step-by-Step Instructions
Step 1: Locate the OBD2 Port
The OBD2 port in a 2013 Dodge Journey is typically located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector that looks like a trapezoid. You may need to crouch down or use a flashlight to find it.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s securely connected. Some scanners will power on automatically when plugged in.
Step 3: Turn the Ignition to “On”
Turn the key to the “ON” position (but don’t start the engine). This powers up the vehicle’s electrical system and allows the scanner to communicate with the ECU.
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to retrieve the diagnostic trouble codes (DTCs). Most scanners will display codes like “P0457” (loose gas cap) or “P0302” (cylinder 2 misfire). Write down the codes or take a photo for reference.
Step 5: Diagnose and Fix the Issue
Use the codes to identify the problem. You can search online for “2013 Dodge Journey P0457 fix” or consult a repair manual. For example, a P0457 code usually means the gas cap needs to be tightened or replaced.
Step 6: Clear the Codes
Once the issue is resolved, return to the scanner and select the option to “Clear Codes” or “Erase DTCs.” The scanner will send a command to the ECU to reset the check engine light.
Step 7: Verify the Reset
Turn the ignition off, wait 10 seconds, then turn it back on. The check engine light should be off. If it comes back on immediately, the problem may not be fully resolved.
Tips for Using an OBD2 Scanner
- Choose a scanner with live data and code definitions for better diagnostics.
- Some advanced scanners can monitor real-time engine parameters like RPM, coolant temperature, and fuel trim.
- If you’re unsure about a code, consult a mechanic or use free resources like OBD-Codes.com.
Method 2: Driving Cycle (Automatic Reset)
In some cases, the check engine light will turn off on its own after the issue is fixed—this is called a “driving cycle.” The vehicle’s computer runs a series of self-tests during normal driving, and if all systems pass, it clears the code and turns off the light.
What Is a Driving Cycle?
A driving cycle is a specific pattern of driving that allows the ECU to complete its diagnostic tests. For the 2013 Dodge Journey, a typical driving cycle includes:
- Cold start (engine off for at least 8 hours)
- Idle for 2–3 minutes
- Drive at varying speeds (city and highway)
- Accelerate and decelerate smoothly
- Reach highway speeds (55–65 mph) and maintain for 5–10 minutes
- Come to a complete stop and idle again
How to Perform a Driving Cycle
Step 1: Fix the Underlying Issue
Before starting the driving cycle, make sure the problem that triggered the light has been resolved. For example, if the gas cap was loose, tighten or replace it.
Step 2: Start with a Cold Engine
Begin the cycle first thing in the morning after the vehicle has been parked overnight. This ensures the engine is cold and the ECU can run cold-start diagnostics.
Step 3: Follow the Driving Pattern
Drive according to the cycle described above. Avoid aggressive driving, sudden stops, or excessive idling.
Step 4: Complete Multiple Cycles if Needed
Some monitors (like the catalytic converter or oxygen sensor tests) may require more than one driving cycle to complete. It can take 3–5 full cycles over several days.
Step 5: Check the Light
After completing the cycles, check the dashboard. If the light remains off, the reset was successful. If it returns, the issue may still exist.
Limitations of the Driving Cycle Method
- Not all codes can be cleared this way—some require a scanner.
- It can take several days of driving to complete all monitors.
- If the light comes back on, the problem likely wasn’t fully fixed.
Method 3: Disconnecting the Battery (Last Resort)
Disconnecting the battery is a quick way to reset the check engine light, but it comes with trade-offs. This method forces the ECU to reset by cutting power, but it also erases stored data like radio presets, adaptive fuel trims, and learned driving patterns.
When to Use This Method
Only use this method if:
- You don’t have access to an OBD2 scanner.
- The light came on due to a temporary glitch (e.g., after refueling).
- You’ve already fixed the issue and want a quick reset.
Step-by-Step Instructions
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is completely off and the key is out of the ignition.
Step 2: Locate the Battery
In the 2013 Dodge Journey, the battery is in the engine compartment on the driver’s side.
Step 3: Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery terminal. Remove the cable and secure it away from the battery post to prevent accidental contact.
Step 4: Wait 15–30 Minutes
This allows the ECU’s capacitors to discharge and the system to fully reset. Some recommend waiting up to an hour for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely.
Step 6: Start the Vehicle
Turn the ignition on and check if the check engine light is off. It may take a few minutes for the system to reboot.
Drawbacks of Battery Disconnection
- Radio presets and clock settings will be lost.
- Adaptive learning (fuel trims, shift points) resets, which may cause rough driving for a few days.
- Some vehicles may require a throttle body relearn procedure.
- Does not guarantee the light won’t return if the issue persists.
Troubleshooting Common Issues After Reset
Even after resetting the light, you may encounter problems. Here’s how to handle them:
The Light Comes Back On Immediately
This usually means the underlying issue wasn’t fixed. For example, if you cleared a P0420 (catalytic converter efficiency) code but didn’t replace the converter, the light will return. Recheck the trouble codes and address the root cause.
The Light Returns After a Few Days
This could indicate an intermittent problem, such as a loose wire or a sensor that fails under certain conditions. Use the OBD2 scanner to check for pending codes—these are codes that haven’t yet triggered the light but are being monitored.
Vehicle Runs Poorly After Reset
If your Journey feels sluggish or hesitates after a reset, the ECU may be relearning driving patterns. Drive normally for 50–100 miles to allow the system to adapt. Avoid aggressive driving during this time.
Check Engine Light Flashes
A flashing light indicates a severe misfire that can damage the catalytic converter. Pull over safely, turn off the engine, and have the vehicle towed to a repair shop. Do not continue driving.
Preventing Future Check Engine Lights
The best way to avoid dealing with the check engine light is through regular maintenance. Here are some tips to keep your 2013 Dodge Journey running smoothly:
- Check the gas cap regularly: Make sure it’s tight after every fill-up. Replace it if it’s cracked or worn.
- Follow the maintenance schedule: Replace spark plugs, air filters, and fuel filters as recommended in your owner’s manual.
- Use quality fuel: Low-quality gasoline can cause carbon buildup and sensor issues.
- Address warning lights promptly: Don’t ignore the light—early diagnosis saves money and prevents damage.
- Keep the engine clean: Regular oil changes and using fuel system cleaners can help prevent sensor fouling.
Conclusion
Resetting the check engine light on your 2013 Dodge Journey doesn’t have to be stressful. Whether you use an OBD2 scanner, complete a driving cycle, or disconnect the battery, the key is to diagnose the problem first. Simply turning off the light without fixing the issue is a temporary fix that can lead to bigger problems down the road.
The OBD2 scanner method is the most reliable and recommended approach, giving you insight into what’s wrong and allowing you to clear codes safely. The driving cycle method is useful for minor issues that resolve on their own, while battery disconnection should be a last resort due to its side effects.
Remember, the check engine light is your vehicle’s way of saying, “Hey, something’s not right.” Listen to it, take action, and keep your Journey running strong for years to come.
