Some of these issues are easy to fix. Others require professional attention. The key is to diagnose the problem first—never just reset the light and hope it stays off.
Tools You’ll Need
To properly turn off the check engine light on your 2013 Kia Soul, you’ll need a few basic tools. Most are affordable and easy to find.
OBD2 Scanner
This is the most important tool. An OBD2 scanner plugs into your car’s diagnostic port and reads the trouble codes stored in the engine control unit (ECU). You can buy a basic scanner for under $20 or invest in a more advanced model with live data and code definitions.
Basic Hand Tools
You may need a socket wrench, screwdriver, or pliers to access components like the gas cap, air filter, or sensor connectors.
Replacement Parts (If Needed)
Depending on the issue, you might need a new gas cap, spark plugs, or air filter. Check your owner’s manual or consult a parts store for the correct replacements.
Safety Gear
Always wear safety glasses and gloves when working under the hood. Make sure the engine is off and cool before starting.
Step 1: Locate the OBD2 Port
The first step in turning off the check engine light is connecting your OBD2 scanner. To do that, you need to find the diagnostic port.
Where to Find It
In the 2013 Kia Soul, 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 rectangular connector with 16 pins—it’s often covered by a small plastic panel.
How to Access It
If there’s a cover, gently pull it off. The port should be clearly visible. Make sure the area is clean and free of dust before plugging in your scanner.
Step 2: Read the Trouble Codes
Now that you’ve found the port, it’s time to read the codes. This tells you exactly what’s causing the check engine light.
Plug In the Scanner
Turn the ignition to the “ON” position (but don’t start the engine). Plug the OBD2 scanner into the port. Most scanners will power on automatically.
Follow the Scanner’s Instructions
Press the “Scan” or “Read Codes” button. The scanner will communicate with the car’s computer and display one or more trouble codes. These codes usually start with a letter (like P, B, C, or U) followed by four numbers (e.g., P0420).
Write Down the Codes
Note down all the codes shown. Even if the scanner gives a brief description, write it down. You’ll need this information to fix the problem.
Example: P0420 Code
A common code in the 2013 Kia Soul is P0420, which means “Catalyst System Efficiency Below Threshold.” This often points to a failing catalytic converter, but it could also be caused by a bad O2 sensor or exhaust leak.
Step 3: Diagnose the Problem
Once you have the codes, it’s time to figure out what’s wrong. Use the codes to guide your diagnosis.
Use a Code Lookup Tool
Most OBD2 scanners come with a code library. If yours doesn’t, use a free online tool like OBD-Codes.com or your scanner’s companion app. Enter the code to get a detailed explanation.
Check Common Causes
Here are some frequent issues in the 2013 Kia Soul and how to check them:
Loose or Damaged Gas Cap
This is the #1 cause of check engine lights in many cars. A loose cap allows fuel vapors to escape, triggering an evaporative emissions code (like P0455).
- Turn off the engine.
- Open the fuel door and unscrew the gas cap.
- Inspect the cap for cracks or a damaged seal.
- Tighten it firmly until you hear it click 3–5 times.
- If the cap is damaged, replace it with an OEM or high-quality aftermarket cap.
Faulty Oxygen Sensor
The O2 sensor monitors exhaust gases and helps the engine adjust the air-fuel mixture. A bad sensor can cause poor fuel economy and emissions issues.
- Locate the sensor(s)—there’s usually one before and after the catalytic converter.
- Check for corrosion, damage, or loose wiring.
- Use a multimeter to test resistance (if you’re experienced).
- Replace if faulty—this often requires a special O2 sensor socket.
Worn Spark Plugs or Ignition Coils
Bad spark plugs can cause misfires, reducing performance and triggering codes like P0300 (random misfire).
- Remove the ignition coil(s) using a socket wrench.
- Pull out the spark plugs and inspect them.
- Look for fouling, cracking, or excessive wear.
- Replace with the correct type (check your owner’s manual).
- Reinstall coils and plugs, then torque to spec.
Dirty Mass Airflow (MAF) Sensor
The MAF sensor measures how much air enters the engine. Dirt or oil buildup can cause inaccurate readings.
- Locate the MAF sensor—usually between the air filter and throttle body.
- Unplug the electrical connector.
- Remove the sensor using a screwdriver or socket.
- Spray with MAF cleaner (do not use water or compressed air).
- Let it dry completely before reinstalling.
Step 4: Fix the Problem
After diagnosing the issue, it’s time to fix it. Some repairs are quick and easy. Others may require more time or tools.
Simple Fixes
If the problem is a loose gas cap or dirty air filter, you can fix it in minutes. Tighten the cap or replace the filter, then proceed to reset the light.
Moderate Repairs
Replacing spark plugs or cleaning the MAF sensor takes about 30–60 minutes. Follow your repair manual or watch a YouTube tutorial specific to the 2013 Kia Soul.
Complex Issues
If the code points to a catalytic converter, EGR valve, or internal engine problem, it’s best to consult a mechanic. These repairs can be expensive and require specialized tools.
Step 5: Clear the Check Engine Light
Once the problem is fixed, you can safely turn off the check engine light. Here’s how:
Use the OBD2 Scanner
This is the safest and most reliable method.
- With the ignition on (engine off), plug in the scanner.
- Navigate to the “Clear Codes” or “Erase DTCs” option.
- Confirm the action when prompted.
- The scanner will reset the ECU and turn off the check engine light.
Wait and See
After clearing the codes, start the engine. The light should be off. If it comes back on within a few days, the problem wasn’t fully resolved.
Alternative Methods (Not Recommended)
Some people try to turn off the check engine light by disconnecting the battery. While this can work, it’s not the best approach.
Disconnecting the Battery
Turning off the ignition, disconnecting the negative battery terminal, and waiting 10–15 minutes can reset the ECU. However, this method:
- May not clear all codes
- Resets radio presets, clock, and other settings
- Can trigger other warning lights
- Doesn’t address the root cause
Only use this method if you don’t have an OBD2 scanner and need a temporary fix. Always diagnose the problem first.
Troubleshooting: What If the Light Comes Back On?
If the check engine light returns after you’ve cleared it, don’t panic—but don’t ignore it either. Here’s what to do:
Re-scan for Codes
Use your OBD2 scanner to read the new or recurring codes. The issue may be more serious than you thought.
Check for Intermittent Problems
Some issues, like a loose wire or failing sensor, only show up under certain conditions (e.g., cold starts or highway driving). Drive the car normally for a few days and monitor the light.
Inspect Related Systems
For example, if you replaced the gas cap but the light returns, check the evaporative emissions system for leaks using a smoke machine (best done at a shop).
Visit a Mechanic
If you’ve tried everything and the light keeps coming back, it’s time for professional help. A certified technician can perform advanced diagnostics and repair complex issues.
Preventing Future Check Engine Lights
The best way to avoid dealing with the check engine light is to prevent it from coming on in the first place. Here are some tips:
