Common causes of the engine light in a 2015 Kia Soul include:
- Loose, damaged, or missing gas cap
- Faulty oxygen (O2) sensor
- Misfiring engine or worn spark plugs
- Catalytic converter issues
- Mass airflow (MAF) sensor problems
- Evaporative emissions system leaks
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. That’s why it’s crucial to diagnose the issue before attempting to reset the light.
Tools You’ll Need
Depending on the method you choose, you may need a few tools. Here’s what to have on hand:
- OBD2 scanner: A handheld device that plugs into your car’s diagnostic port to read and clear trouble codes. Affordable models are available online or at auto parts stores.
- Socket wrench or flathead screwdriver: For disconnecting the battery (if using the battery method).
- Owner’s manual: To locate the diagnostic port and understand your vehicle’s specific systems.
- Gloves and safety glasses: For protection when working under the hood.
While you can reset the light without a scanner, using one gives you valuable insight into what triggered the warning in the first place.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most effective way to reset the engine light on your 2015 Kia Soul is by using an OBD2 scanner. This method allows you to read the trouble code, understand the problem, and clear the light—all without risking damage to your vehicle’s electronics.
Step 1: Locate the OBD2 Port
The OBD2 port in a 2015 Kia Soul 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. Refer to your owner’s manual if you’re having trouble locating it.
Step 2: Turn Off the Engine
Make sure your vehicle is completely turned off before plugging in the scanner. This prevents any electrical interference and ensures accurate readings.
Step 3: Plug in the OBD2 Scanner
Insert the scanner’s plug into the OBD2 port. Most scanners will power on automatically when connected. If not, turn the ignition to the “ON” position (without starting the engine) to supply power.
Step 4: Read the Trouble Code
Follow the scanner’s instructions to retrieve the trouble code. The code will appear as a series of letters and numbers, such as P0457 (indicating a gas cap issue) or P0301 (cylinder 1 misfire). Write down the code for reference.
Step 5: Diagnose the Issue
Use the scanner’s built-in code definitions or search online to understand what the code means. For example, a P0420 code often points to a failing catalytic converter, while a P0171 suggests a lean fuel mixture.
Step 6: Fix the Problem
Once you’ve identified the issue, take steps to resolve it. For instance, if the code indicates a loose gas cap, tighten it or replace it if damaged. If it’s a sensor issue, you may need to replace the part or have it inspected by a mechanic.
Step 7: Clear the Code
After fixing the problem, use the scanner’s “Clear Codes” or “Reset” function to turn off the engine light. The scanner will send a signal to the vehicle’s computer to erase the stored trouble code.
Step 8: Verify the Reset
Start your engine and check the dashboard. The engine light should be off. If it remains on or comes back shortly after, the issue may not be fully resolved, or there could be additional problems.
Pro Tip: Some advanced OBD2 scanners can also monitor live data, such as engine temperature and oxygen sensor readings, helping you confirm that repairs were successful.
Method 2: Disconnecting the Battery (Alternative Method)
If you don’t have an OBD2 scanner, you can try resetting the engine light by disconnecting the car battery. This method forces the vehicle’s computer to reset, clearing stored codes and turning off the light. However, it’s less precise and may not address the root cause.
Step 1: Turn Off the Engine and Remove the Key
Ensure the vehicle is completely off and the key is removed from the ignition. This prevents accidental electrical shorts.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2015 Kia Soul, it’s located on the right side of the engine bay. Wear gloves and safety glasses for protection.
Step 3: Disconnect the Negative Terminal
Use a socket wrench or wrench to loosen the nut on the negative (-) terminal (usually black). Carefully remove the cable and set it aside, making sure it doesn’t touch the battery post.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer (ECU) to fully discharge and reset. Some sources recommend up to 30 minutes for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is tight to avoid electrical issues.
Step 6: Start the Engine
Turn the ignition and start the car. The engine light should be off. If it remains on, the issue may still be present.
Important Notes:
- Disconnecting the battery will reset other systems, including your radio presets, clock, and sometimes the anti-theft system. You may need to re-enter security codes or reprogram settings.
- This method does not fix the underlying problem—it only clears the code. If the issue persists, the light will return.
- Avoid disconnecting the positive terminal unless necessary, as it increases the risk of short circuits.
Method 3: Tightening or Replacing the Gas Cap
One of the most common reasons for the engine light to come on in a 2015 Kia Soul is a loose or faulty gas cap. The gas cap seals the fuel system, preventing fuel vapors from escaping. If it’s not tight or is damaged, the OBD2 system detects a leak and triggers the engine light.
Step 1: Turn Off the Engine
Park your vehicle and turn off the engine. Allow it to cool if you’ve been driving.
Step 2: Locate the Gas Cap
Open the fuel door on the driver’s side of the vehicle. Unscrew the gas cap by turning it counterclockwise.
Step 3: Inspect the Cap
Check the gas cap for cracks, worn rubber seals, or damage. A damaged cap won’t create a proper seal and must be replaced.
Step 4: Tighten the Cap
If the cap appears intact, screw it back on tightly. You should hear a clicking sound as it seals. Some models have a torque-limiting feature that clicks when properly tightened.
Step 5: Drive and Monitor
Drive your vehicle for a few miles. The engine light may turn off automatically after the system confirms the leak is fixed. This can take anywhere from a few minutes to a few days, depending on driving conditions.
Pro Tip: If the light doesn’t go off after a few days, use an OBD2 scanner to check for the specific code. A P0455 or P0457 code confirms a gas cap issue.
Troubleshooting Common Issues
Even after resetting the engine light, you may encounter problems. Here’s how to troubleshoot common scenarios:
Engine Light Comes Back On
If the light returns shortly after resetting, the original issue hasn’t been resolved. Use an OBD2 scanner to check for new or recurring codes. Persistent codes may indicate a failing sensor, electrical problem, or mechanical issue requiring professional diagnosis.
Light Flashes After Reset
A flashing engine light indicates a severe problem, such as engine misfire or catalytic converter damage. Stop driving immediately and have the vehicle towed to a repair shop. Continuing to drive can cause expensive damage.
Radio or Clock Resets After Battery Disconnection
This is normal when disconnecting the battery. Re-enter your radio presets and reset the clock. Some vehicles may require a security code to restore the radio—check your owner’s manual.
OBD2 Scanner Doesn’t Work
Ensure the scanner is compatible with your 2015 Kia Soul and properly connected. Try turning the ignition to “ON” without starting the engine. If the scanner still doesn’t respond, test it on another vehicle or replace the batteries.
No Codes Found but Light Is On
In rare cases, the engine light may illuminate due to a software glitch or intermittent issue. Try driving the vehicle for a few days to see if the light turns off on its own. If not, have a mechanic perform a full diagnostic scan.
