Why the Check Engine Light Comes On
Before you reset the check engine light, it’s crucial to understand *why* it turned on in the first place. The light is part of your vehicle’s onboard diagnostics system (OBD2), which monitors engine performance, emissions, and various sensors. When something goes outside normal parameters, the system stores a trouble code and illuminates the check engine light.
Common reasons the light appears on a 2013 Honda CR-V include:
- Loose or faulty gas cap: This is one of the most frequent causes. A loose cap allows fuel vapors to escape, triggering an evaporative emissions code (P0455 or similar).
- Oxygen (O2) sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A faulty O2 sensor can reduce fuel efficiency and increase emissions.
- Spark plug or ignition coil issues: Misfires (code P0300-P0304) often result from worn spark plugs or failing coils, leading to rough idling and poor performance.
- Catalytic converter problems: A failing converter (often code P0420) reduces emissions efficiency and can hurt performance over time.
- Mass airflow (MAF) sensor dirt or damage: This sensor measures incoming air. If it’s dirty or faulty, the engine may run rich or lean.
- Exhaust gas recirculation (EGR) valve issues: A clogged or stuck EGR valve can cause rough idle and increased emissions.
Ignoring the light can lead to decreased fuel economy, increased emissions, and even engine damage. That’s why diagnosing the root cause is the first and most important step.
Tools You’ll Need
To reset the check engine light on your 2013 Honda CR-V, you’ll need a few basic tools. Most are affordable and easy to use, even for beginners.
OBD2 Scanner
This is the most reliable tool for reading and clearing trouble codes. Modern OBD2 scanners plug into the diagnostic port (usually under the dashboard near the steering wheel) and display the specific code causing the light. Many models also allow you to reset the light with the press of a button. Look for a basic code reader (around $20–$50) or a more advanced scanner with live data and reset capabilities.

Owner’s Manual
Your 2013 Honda CR-V owner’s manual contains valuable information about the check engine light, including what it means and how to respond. It also shows the location of the OBD2 port and battery terminals.
Basic Hand Tools
If you plan to disconnect the battery, you’ll need a wrench or socket set (usually 10mm) to remove the negative terminal. Keep a cloth or towel handy to prevent accidental contact.
Pen and Paper (or Phone)
Write down the trouble code and any symptoms before resetting. This helps track repairs and diagnose recurring issues.
Step 1: Diagnose the Problem
Never reset the check engine light without first diagnosing the issue. Clearing the light without fixing the problem is like turning off a smoke alarm while the house is on fire—it doesn’t solve anything.
Locate the OBD2 Port
In the 2013 Honda CR-V, the OBD2 port is typically located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector, usually black or gray, and may be covered by a small flap. If you can’t find it, consult your owner’s manual.
Plug in the OBD2 Scanner
Turn the ignition to the “ON” position (but don’t start the engine). Plug the scanner into the OBD2 port. Most scanners will power on automatically. Follow the on-screen prompts to read the trouble codes.
Read and Record the Code
The scanner will display a code like P0420 or P0171. Write it down. You can then look up the code online or in a repair manual to understand what it means. For example, P0420 usually indicates a catalytic converter efficiency issue, while P0171 means the engine is running too lean.
Assess the Severity
Some codes are minor (like a loose gas cap), while others require immediate attention (like a misfire). If the light is flashing, it indicates a serious misfire that can damage the catalytic converter—get it checked right away.
Step 2: Fix the Underlying Issue
Once you’ve identified the problem, take steps to fix it. Here are common fixes for the 2013 Honda CR-V:
Tighten or Replace the Gas Cap
If the code points to an evaporative emissions leak (e.g., P0455), start by checking the gas cap. Make sure it’s tight—turn it until you hear three clicks. If the cap is cracked, worn, or missing its seal, replace it with a genuine Honda part or high-quality aftermarket cap.
Replace Faulty Sensors
For O2 sensor or MAF sensor issues, you may need to replace the component. O2 sensors are located in the exhaust system and can be accessed from underneath the vehicle. The MAF sensor is usually near the air filter box. Use a torque wrench and follow torque specs to avoid damage.
Replace Spark Plugs or Ignition Coils
If you have a misfire code, inspect the spark plugs. On the 2013 CR-V, the 2.4L engine has four spark plugs, each under a coil. Remove the coil (usually held by one bolt), then use a spark plug socket to remove and inspect the plug. Replace if worn, fouled, or beyond the recommended interval (typically 100,000 miles).
Clean the MAF Sensor
If the MAF sensor is dirty but not damaged, you can clean it with MAF sensor cleaner (not regular spray cleaner). Remove the sensor, spray it gently, and let it dry completely before reinstalling.
Address Catalytic Converter Issues
A failing catalytic converter often requires replacement, which can be expensive. However, sometimes the issue is caused by repeated misfires damaging the converter. Fix the misfire first, then monitor the code. If it returns, the converter may need replacement.
Step 3: Reset the Check Engine Light
After fixing the problem, it’s time to reset the check engine light. There are three main methods: using an OBD2 scanner, performing a driving cycle, or disconnecting the battery. We’ll cover each in detail.
Method 1: Use an OBD2 Scanner (Recommended)
This is the safest and most effective way to reset the light.
Step-by-Step Instructions:
- Ensure the repair is complete and the vehicle is off.
- Turn the ignition to “ON” (do not start the engine).
- Plug the OBD2 scanner into the port.
- Navigate to the “Clear Codes” or “Erase Codes” option on the scanner.
- Confirm the reset when prompted.
- The scanner will display “Codes Cleared” or similar.
- Turn off the ignition and unplug the scanner.
After resetting, start the engine. The check engine light should be off. If it comes back on, the problem may not be fully resolved, or a new issue has occurred.
Method 2: Perform a Driving Cycle
Some vehicles will automatically clear the check engine light after a series of driving conditions, known as a “drive cycle.” This allows the onboard computer to retest systems and confirm the issue is fixed.
Honda CR-V Drive Cycle Example:
- Start the engine and let it idle for 2–3 minutes (cold start).
- Drive at 30–40 mph for 5 minutes with steady throttle.
- Accelerate to 55 mph and maintain speed for 5 minutes.
- Decelerate to 20 mph without braking (coast).
- Repeat the cycle 2–3 times.
- End with a 5-minute idle.
After completing the drive cycle, the check engine light may turn off if the system confirms no errors. This method can take several days of normal driving.
Method 3: Disconnect the Battery (Last Resort)
Disconnecting the battery can reset the check engine light by clearing the vehicle’s memory. However, this method has downsides and should only be used if other methods fail.
Step-by-Step Instructions:
- Turn off the engine and remove the key.
- Open the hood and locate the battery (front passenger side).
- Use a 10mm wrench to loosen the negative (black) terminal clamp.
- Remove the negative cable and wrap it in a cloth to prevent contact.
- Wait 15–30 minutes (this allows the ECU to fully reset).
- Reconnect the negative terminal and tighten securely.
- Start the engine and check if the light is off.
Warning: Disconnecting the battery may reset radio presets, clock, and adaptive learning (like idle speed and shift points). You may need to relearn these settings by driving for a few miles.
Troubleshooting: What If the Light Comes Back On?
If the check engine light returns after resetting, 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 code. It may be the same issue or a different one.
Check for Intermittent Problems
Some issues, like a loose gas cap or minor sensor glitch, may come and go. Recheck connections, seals, and wiring.
Monitor Driving Conditions
Did the light come on after filling up with gas? It could be a bad batch of fuel or a loose cap. Try tightening the cap and driving for a few days.
Consult a Mechanic
If the light persists or you’re unsure of the repair, take your CR-V to a trusted mechanic. They have advanced tools and experience to diagnose complex issues.
Check for Recalls or TSBs
Honda occasionally issues Technical Service Bulletins (TSBs) or recalls for known issues. Visit the Honda website or contact a dealer with your VIN to check.
