Why Is the Engine Light On?
Before you reset the engine light, it’s important to understand what triggered it. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, fuel system, and other critical components.

The light can come on for a wide range of reasons, from something as simple as a loose gas cap to more serious issues like a failing oxygen sensor or catalytic converter. In the 2017 Dodge Journey, common causes include:
- Loose or damaged gas cap: This is the #1 cause of a check engine light. If the cap isn’t sealed properly, fuel vapors can escape, triggering the light.
- Faulty oxygen (O2) sensor: These sensors monitor exhaust gases and help regulate fuel mixture. A bad sensor can reduce fuel efficiency and increase emissions.
- Spark plug or ignition coil issues: Misfires can cause rough idling, poor acceleration, and trigger the light.
- Mass airflow (MAF) sensor problems: This sensor measures how much air enters the engine. Dirt or damage can throw off fuel calculations.
- Catalytic converter failure: Often caused by long-term neglect, a failing converter can lead to reduced performance and increased emissions.
- Evaporative emissions system leak: A small leak in the fuel vapor system can set off the light.
Knowing the cause helps you decide whether a simple reset is safe or if you need professional help. For example, if your Journey is running rough or losing power, don’t just reset the light—get it checked.
Method 1: The Gas Pedal Trick (No Tools Required)
One of the easiest ways to reset the engine light on a 2017 Dodge Journey is the “gas pedal method.” This technique uses the vehicle’s onboard computer to clear stored error codes after a problem has been fixed. It’s especially useful after tightening a loose gas cap or replacing a minor component.
This method works because the car’s computer runs a series of self-tests (called drive cycles) to confirm that the issue is resolved. Once all tests pass, the light turns off automatically. The gas pedal trick helps initiate this process.
Step-by-Step Instructions
- Turn the ignition to “ON” (but don’t start the engine): Insert the key and turn it to the second position (where the dashboard lights up). Do not press the brake or start the engine.
- Press and release the gas pedal three times within 10 seconds: Press the accelerator all the way to the floor, then release it completely. Do this three times in quick succession. You should hear the fuel pump activate briefly.
- Turn the ignition off and wait 1–2 minutes: Remove the key and let the vehicle sit. This allows the computer to reset.
- Start the engine and check the light: Turn the key to start the engine. If the issue was minor (like a loose gas cap), the light should be off. If it remains on, the problem may still exist.
Tips for Success
- Make sure the gas cap is tight before trying this method. A loose cap is the most common fixable cause.
- This method may not work for serious issues like engine misfires or sensor failures.
- If the light turns off but comes back after a few days, the problem wasn’t fully resolved.
This trick is quick, free, and doesn’t require any tools. It’s a great first step if you’ve just fixed a minor issue and want to see if the light clears on its own.
Method 2: Using an OBD2 Scanner (Recommended)
The most reliable way to reset the engine light on your 2017 Dodge Journey is with an OBD2 (On-Board Diagnostics) scanner. This device plugs into your car’s diagnostic port and communicates directly with the engine control unit (ECU). It can read error codes, explain what they mean, and clear the light—all in minutes.
OBD2 scanners are affordable (many cost under $30) and widely available online or at auto parts stores. Even basic models can read and clear codes, making them a smart investment for any car owner.
Where to Find the OBD2 Port
In the 2017 Dodge Journey, the OBD2 port is located under the dashboard on the driver’s side. It’s usually near the steering column, about knee-level. Look for a 16-pin connector—it’s rectangular and easy to spot once you know where to look.
Step-by-Step Instructions
- Turn off the engine and locate the OBD2 port: Make sure the car is off and the key is removed. Find the port under the dashboard.
- Plug in the OBD2 scanner: Insert the scanner’s connector firmly into the port. Most scanners will power on automatically.
- Turn the ignition to “ON” (do not start the engine): This gives the scanner power to communicate with the ECU.
- Follow the scanner’s prompts to read codes: Use the menu to select “Read Codes” or “Scan.” The device will display one or more diagnostic trouble codes (DTCs), such as P0457 (loose gas cap) or P0171 (system too lean).
- Write down the codes: Before clearing them, jot down the codes and their descriptions. This helps if you need to visit a mechanic later.
- Clear the codes: Select “Clear Codes” or “Erase DTCs.” The scanner will send a command to reset the engine light.
- Turn off the ignition and unplug the scanner: Wait a few seconds, then remove the device.
- Start the engine and check the dashboard: The check engine light should be off. If it returns, the underlying issue hasn’t been fixed.
Tips for Using an OBD2 Scanner
- Choose a scanner with a clear display and easy navigation. Bluetooth models that connect to your phone are also available.
- Some scanners offer live data, freeze frame data, and code definitions—great for diagnosing problems.
- If you get a code you don’t understand, search it online or use the scanner’s built-in database.
- After clearing codes, drive the car for a few days to see if the light returns. The ECU needs time to run its tests.
Using an OBD2 scanner gives you full control over the diagnostic process. It’s the best way to ensure the light is reset properly and that your Journey is running as it should.
Method 3: Disconnecting the Battery
Another way to reset the engine light is by disconnecting the car battery. This method cuts power to the ECU, forcing it to reset and clear stored error codes. It’s a bit more invasive than the other methods and should be used as a last resort.
While this technique can work, it has downsides. Disconnecting the battery resets not only the engine light but also other systems like the radio presets, clock, and sometimes even the transmission shift points. It may also trigger other warning lights temporarily.
Step-by-Step Instructions
- Turn off the engine and remove the key: Make sure the car is completely off.
- Locate the battery: In the 2017 Dodge Journey, the battery is in the engine compartment on the driver’s side.
- Disconnect the negative terminal: Use a wrench to loosen the nut on the negative (black) battery cable. Remove the cable and tuck it away from the battery post.
- Wait 10–15 minutes: This allows the ECU to fully discharge and reset. Some experts recommend waiting up to 30 minutes for a complete reset.
- Reconnect the negative terminal: Reattach the cable and tighten the nut securely.
- Start the engine and check the light: Turn the key and see if the check engine light is off. You may need to drive the car for a few miles for the system to relearn.
Important Considerations
- This method may not clear all codes permanently. If the issue persists, the light will return.
- Some vehicles require a “relearn” procedure after battery disconnect, especially for the transmission or throttle body.
- If your Journey has a security system or keyless entry, you may need to reprogram it.
- Always wear safety glasses and avoid touching both battery terminals at once.
Disconnecting the battery is a brute-force method. It can work in a pinch, but it’s not the most precise or recommended approach. Use it only if other methods fail and you’re prepared for the side effects.
Troubleshooting Common Issues
Even after resetting the engine light, you might run into problems. Here’s how to handle common scenarios:
The Light Comes Back On
If the check engine light returns after a reset, the underlying issue wasn’t fixed. For example, if you tightened the gas cap but the light came back, the cap might be damaged or the evaporative emissions system could have a leak.
Solution: Use an OBD2 scanner to read the new codes. Compare them to the original ones. If they’re the same, the problem persists. If they’re different, a new issue may have developed.
The Light Flashes Instead of Staying Solid
A flashing check engine light indicates a severe problem, such as a major engine misfire. This can damage the catalytic converter if ignored.
Solution: Pull over safely and turn off the engine. Have the vehicle towed to a repair shop. Do not drive with a flashing light.
The Reset Doesn’t Work
If none of the methods work, the issue may be more complex. The ECU might be storing pending codes, or the problem could be intermittent.
Solution: Visit a mechanic or auto parts store. Many stores offer free code reading. They can help diagnose the issue and recommend repairs.
Other Warning Lights Appear
After a battery disconnect, you might see lights for the ABS, airbag, or transmission. These usually go away after a short drive as the systems relearn.
Solution: Drive the car for 10–15 minutes at varying speeds. If the lights stay on, have the vehicle scanned for additional codes.
Preventing Future Engine Light Warnings
The best way to deal with the check engine light is to prevent it from coming on in the first place. Regular maintenance and good driving habits can go a long way.
Check the Gas Cap Regularly
After every fill-up, make sure the gas cap is tight. A loose or missing cap is the easiest fix—and the most common cause of the light.
Follow the Maintenance Schedule
Your 2017 Dodge Journey has a recommended maintenance schedule in the owner’s manual. Stick to it for oil changes, air filter replacements, spark plug checks, and more.
Use Quality Fuel and Oil
Cheap fuel or low-quality oil can lead to engine deposits and sensor issues. Use top-tier gasoline and the correct oil grade (usually 5W-20 or 5W-30).
Watch for Performance Changes
If your Journey starts running rough, hesitating, or getting worse gas mileage, don’t ignore it. These are early signs of a problem that could trigger the light.
Keep an OBD2 Scanner Handy
Invest in a basic scanner and keep it in your glove box. It’s a small tool that can save you time, money, and stress.
Conclusion
Resetting the engine light on a 2017 Dodge Journey is easier than you might think.
