Before you reset the engine light, it’s crucial to understand why it came on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is triggered when your car’s onboard computer (ECU) detects a problem with the engine, emissions system, or related components.
Common causes in the 2013 Veloster include:
- A loose or damaged gas cap
- Faulty oxygen (O2) sensor
- Misfiring engine
- Catalytic converter issues
- Mass airflow (MAF) sensor problems
- Spark plug or ignition coil failure
- Evaporative emissions (EVAP) system leaks
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. That’s why diagnosing the issue is the first and most important step.
Step 1: Diagnose the Problem with an OBD2 Scanner
The best way to understand why your check engine light is on is to read the trouble codes stored in your car’s computer. This is done using an OBD2 (On-Board Diagnostics) scanner.
What Is an OBD2 Scanner?
An OBD2 scanner is a small handheld device that plugs into your car’s OBD2 port—usually located under the dashboard, near the steering wheel. It communicates with your car’s ECU and retrieves diagnostic trouble codes (DTCs), which tell you exactly what’s wrong.
How to Use an OBD2 Scanner on a 2013 Veloster
- Locate the OBD2 port: In the 2013 Veloster, it’s typically found under the dashboard on the driver’s side, near the footwell. It’s a 16-pin connector that looks like a trapezoid.
- Turn off the engine: Make sure the car is off before plugging in the scanner.
- Plug in the scanner: Insert the OBD2 scanner into the port firmly.
- Turn the ignition to “ON”: Don’t start the engine—just turn the key to the “ON” position so the dashboard lights up.
- Follow the scanner’s instructions: Most scanners will prompt you to press a button to read codes. Wait for the results.
- Record the codes: The scanner will display codes like P0420 or P0171. Write them down or take a photo.
Interpreting the Codes
Once you have the codes, use the scanner’s manual or an online database (like OBD-Codes.com) to understand what they mean. For example:
- P0420: Catalyst system efficiency below threshold
- P0171: System too lean (bank 1)
- P0300: Random/multiple cylinder misfire detected
This information helps you determine the right fix—whether it’s replacing a sensor, tightening a gas cap, or cleaning a component.
Step 2: Fix the Underlying Issue
Resetting the engine light without fixing the problem is like turning off a smoke alarm while the house is still on fire. The light will likely come back—and the issue could worsen.
Here are common fixes based on typical 2013 Veloster issues:
Loose or Faulty Gas Cap
One of the easiest and most common causes of the check engine light is a loose, cracked, or missing gas cap. The gas cap seals the fuel system and maintains proper pressure. If it’s not tight, the ECU detects a leak in the evaporative emissions system.
How to fix it:
- Turn off the engine and let the car cool.
- Open the fuel door and unscrew the gas cap.
- Inspect the cap for cracks, wear, or a damaged seal.
- If it looks damaged, replace it with a new OEM or compatible gas cap.
- If it’s intact, screw it back on tightly until you hear it click 3–5 times.
- Drive the car for a few days. The light may turn off on its own.
Faulty Oxygen Sensor
The O2 sensor monitors the amount of oxygen in the exhaust gases. A faulty sensor can cause poor fuel economy and increased emissions.
How to fix it:
- Use the OBD2 scanner to confirm the code (e.g., P0135, P0141).
- Locate the sensor—usually on the exhaust manifold or downpipe.
- Disconnect the electrical connector.
- Use an O2 sensor socket to remove the old sensor.
- Install the new sensor and reconnect the wiring.
- Clear the code and test drive.
Engine Misfire
A misfire occurs when one or more cylinders fail to ignite properly. This can be caused by bad spark plugs, ignition coils, or fuel injectors.
How to fix it:
- Check the trouble code to identify which cylinder is misfiring.
- Inspect spark plugs for wear, carbon buildup, or gaps.
- Replace spark plugs if necessary (recommended every 30,000–60,000 miles).
- Test ignition coils with a multimeter or swap them to see if the misfire follows.
- Replace faulty coils or injectors as needed.
Mass Airflow (MAF) Sensor Issues
The MAF sensor measures the amount of air entering the engine. A dirty or faulty sensor can cause rough idling, stalling, or poor acceleration.
How to fix it:
- Locate the MAF sensor—usually between the air filter box and the throttle body.
- Disconnect the electrical connector.
- Remove the sensor using a screwdriver or socket.
- Clean it with MAF sensor cleaner (do not use regular cleaners).
- Reinstall and reconnect.
- Clear the code and test drive.
Step 3: Reset the Engine Light Using an OBD2 Scanner
Once you’ve fixed the issue, it’s time to reset the engine light. The most reliable and recommended method is using an OBD2 scanner.
How to Clear Codes with an OBD2 Scanner
- Plug the scanner into the OBD2 port (engine off).
- Turn the ignition to “ON” (do not start the engine).
- Navigate the scanner menu to “Clear Codes” or “Erase DTCs.”
- Confirm the action when prompted.
- The scanner will display “Codes Cleared” or similar.
- Turn off the ignition and unplug the scanner.
Tip: Some scanners also allow you to view live data or monitor readiness monitors after clearing codes.
Step 4: Use the Drive Cycle Method
If you don’t have an OBD2 scanner, or if the light doesn’t clear after using one, your car may need to complete a “drive cycle.” This is a specific driving pattern that allows the ECU to run self-tests and confirm that the problem is resolved.
What Is a Drive Cycle?
A drive cycle is a series of driving conditions (cold start, highway driving, idling, etc.) that trigger the vehicle’s onboard diagnostics to check various systems. Once all tests pass, the check engine light may turn off automatically.
2013 Veloster Drive Cycle Procedure
Follow these steps to complete a drive cycle:
- Cold Start: Start the engine after it has been off for at least 8 hours (overnight).
- Idle for 2–3 minutes: Let the engine warm up without driving.
- Drive at 30–40 mph for 5 minutes: Maintain steady speed in city traffic.
- Accelerate to 55–60 mph: Drive on the highway for 10–15 minutes.
- Decelerate and coast: Let the car slow down without braking for 2–3 minutes.
- Stop and idle for 2 minutes: Park and let the engine run.
- Turn off the engine: Wait 10 seconds, then restart and drive normally for a few days.
Note: The exact drive cycle may vary slightly depending on the issue. Some systems (like EVAP) require multiple drive cycles to complete.
Step 5: Disconnect the Battery (Last Resort)
If you don’t have a scanner and the drive cycle doesn’t work, you can try disconnecting the car battery to reset the ECU. This method forces the computer to reboot and clear stored codes.
How to Disconnect the Battery
- Turn off the engine and remove the key.
- Open the hood and locate the battery (usually on the driver’s side).
- Use a wrench to loosen the negative (-) terminal clamp.
- Remove the negative cable and tuck it away from the battery.
- Wait 15–30 minutes (this allows the ECU to fully reset).
- Reconnect the negative cable and tighten it securely.
- Close the hood and start the car.
Warning: Disconnecting the battery may reset other systems, including:
- Radio presets and clock
- Power window and sunroof memory
- Adaptive transmission learning
- Security system settings
You may need to reprogram these features after reconnecting the battery.
Troubleshooting: What If the Light Comes Back?
If the check engine light returns after resetting, it means the problem wasn’t fully resolved. Here’s what to do:
Recheck the Trouble Codes
Use your OBD2 scanner to read the new or recurring codes. Compare them to the original ones to see if it’s the same issue or a new one.
Inspect for Intermittent Problems
Some issues, like loose wiring or failing sensors, may not trigger a code immediately. Look for:
- Loose or corroded connectors
- Damaged vacuum hoses
- Worn spark plug wires (if applicable)
- Low fuel pressure
Check for Software Updates
Hyundai occasionally releases ECU software updates to fix known issues. Visit a Hyundai dealership to see if your car needs a reflash.
Consult a Mechanic
If you’ve tried everything and the light keeps coming back, it’s time to see a professional. A certified mechanic can perform advanced diagnostics, such as:
- Smoke testing for EVAP leaks
- Compression testing
- Fuel pressure testing
- Exhaust gas analysis
Ignoring persistent issues can lead to costly repairs down the road.
Preventing Future Check Engine Lights
The best way to avoid resetting the engine light is to prevent it from coming on in the first place. Here are some maintenance tips for your 2013 Veloster:
