Before you reset the check engine light, it’s important to understand what it means. The check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). When the car’s computer detects a problem with the engine, emissions, or other critical systems, it triggers this light to alert you.
On a 2014 Honda CR-V, the light can come on for dozens of reasons, ranging from minor issues like a loose gas cap to more serious problems like a faulty oxygen sensor or catalytic converter. Ignoring the light can lead to reduced fuel efficiency, increased emissions, or even engine damage over time.
That’s why the first step isn’t to reset the light—it’s to figure out why it’s on in the first place. Resetting it without fixing the underlying issue is like turning off a smoke alarm while your kitchen is still on fire. The light will likely come back, and the problem will persist.
Step 1: Diagnose the Problem
The most important step before resetting the check engine light is diagnosing the issue. You can’t fix what you don’t understand, and blindly resetting the light won’t solve anything.
Use an OBD2 Scanner
The best way to diagnose the problem is with an OBD2 scanner. This handheld device plugs into your car’s OBD2 port—usually located under the dashboard, near the driver’s knees—and reads the trouble code stored in the car’s computer.
Here’s how to use one:
- Locate the OBD2 port: In the 2014 Honda CR-V, it’s typically found under the steering column, just above the brake pedal. It’s a 16-pin connector that looks like a trapezoid.
- Plug in the scanner: Turn the ignition to the “ON” position (but don’t start the engine). Insert the scanner into the port and wait for it to power up.
- Read the code: Follow the scanner’s instructions to retrieve the diagnostic trouble code (DTC). It will look something like “P0420” or “P0171.”
- Look up the code: Use the scanner’s built-in database or search online to understand what the code means. For example, P0420 often indicates a problem with the catalytic converter, while P0171 suggests a lean fuel mixture.
Many auto parts stores, like AutoZone or O’Reilly, offer free code reading if you don’t own a scanner. This is a great option if you’re on a budget.
Check Common Causes
While waiting to get a code read, you can check a few common culprits:
- Gas cap: A loose, damaged, or missing gas cap is one of the most frequent causes of the check engine light. Check that it’s tight and the seal isn’t cracked.
- Spark plugs and ignition coils: Worn spark plugs can cause misfires, triggering the light. Inspect them if you’re comfortable doing so.
- Air filter: A dirty air filter can restrict airflow and affect engine performance.
- Oxygen sensors: These monitor exhaust gases and can fail over time, especially in older vehicles.
If you’re not comfortable inspecting these components, it’s best to consult a mechanic.
Step 2: Fix the Underlying Issue
Once you’ve identified the problem, it’s time to fix it. This step is crucial—resetting the light won’t help if the issue remains.
Simple Fixes You Can Do Yourself
Some problems are easy to resolve at home:
- Tighten or replace the gas cap: If the cap is loose, tighten it until it clicks three times. If it’s cracked or worn, replace it with a new OEM or high-quality aftermarket cap.
- Replace the air filter: Open the air filter housing (usually a black plastic box near the engine), remove the old filter, and install a new one. This takes just a few minutes.
- Check for loose wires or connections: Sometimes, a loose sensor wire can trigger a false code. Inspect visible connectors and reseat them if needed.
When to Call a Mechanic
For more complex issues—like a failing catalytic converter, faulty oxygen sensor, or internal engine problems—professional help is recommended. These repairs often require specialized tools and expertise.
For example, replacing an oxygen sensor involves locating the sensor (usually in the exhaust manifold or downpipe), disconnecting the electrical connector, and using a special socket to remove it. While some DIYers can handle this, others may prefer to leave it to a pro.
Step 3: Choose a Method to Reset the Check Engine Light
After the repair is complete, you can reset the check engine light. There are several methods, each with pros and cons. Choose the one that best fits your situation.
Method 1: Use an OBD2 Scanner (Recommended)
Using an OBD2 scanner is the safest and most reliable way to reset the check engine light. It ensures the system is ready and won’t erase important data.
Here’s how:
- Plug in the scanner: Turn the ignition to “ON” and connect the scanner to the OBD2 port.
- Navigate to the reset option: Most scanners have a “Clear Codes” or “Reset MIL” option. Select it.
- Confirm the reset: The scanner will ask if you’re sure. Confirm, and the light should turn off.
- Turn off the ignition and restart: Wait a few seconds, then start the engine to verify the light is off.
Tip: Some scanners also allow you to view live data or run system tests, which can help confirm the repair was successful.
Method 2: Disconnect the Battery
If you don’t have a scanner, you can reset the light by disconnecting the battery. This method forces the car’s computer to reset, clearing stored codes and turning off the light.
Here’s how to do it safely:
- Turn off the engine and remove the key: Make sure the car is completely off.
- Locate the battery: In the 2014 Honda CR-V, the battery is in the engine bay on the driver’s side.
- Disconnect the negative terminal: Use a wrench to loosen the nut on the negative (black) cable. Remove the cable and tuck it away from the battery terminal.
- Wait 15–30 minutes: This allows the car’s computer to fully reset. Some recommend waiting up to an hour for older systems.
- Reconnect the cable: Reattach the negative terminal and tighten the nut securely.
- Start the engine: The check engine light should be off. If it returns, the problem may not be fully resolved.
Warning: Disconnecting the battery can reset other systems, including:
- Radio presets and clock settings
- Adaptive transmission learning (may cause rough shifting temporarily)
- Anti-theft system (may require a reset code for the radio)
To avoid radio issues, you can use a memory saver device that plugs into the OBD2 port or cigarette lighter to maintain power during the reset.
Method 3: Drive Cycle (Natural Reset)
Sometimes, the check engine light will turn off on its own after the problem is fixed. This is called a “drive cycle”—a series of driving conditions that allow the car’s computer to retest the systems and confirm everything is working.
The 2014 Honda CR-V typically requires a mix of city and highway driving over several days. A typical drive cycle includes:
- Starting the engine when cold
- Driving at varying speeds (stop-and-go traffic, highway cruising)
- Reaching operating temperature
- Turning the engine off and on multiple times
After 3–5 days of normal driving, the light may disappear if the issue was minor and fully resolved.
Note: This method only works if the fault is no longer present. If the problem persists, the light will stay on.
Troubleshooting Common Issues
Even after resetting the light, you might run into problems. Here’s how to handle them.
The Light Comes Back On
If the check engine light returns after resetting, it means the underlying issue wasn’t fully fixed. Possible reasons include:
- The repair was incomplete (e.g., replaced a sensor but didn’t clear carbon buildup)
- A related component is also failing
- The code was misread or misinterpreted
Solution: Re-scan the code and double-check your work. If you’re unsure, consult a mechanic.
The Light Won’t Reset
If the light won’t turn off after using a scanner or disconnecting the battery, possible causes are:
- The fault is still active (e.g., a sensor is still faulty)
- The scanner isn’t compatible or functioning properly
- The battery voltage is too low to complete the reset
Solution: Ensure the repair is complete, use a reliable scanner, and check the battery voltage (should be at least 12.4V).
Radio or Settings Reset After Battery Disconnect
As mentioned earlier, disconnecting the battery can reset personal settings. To restore them:
- Re-enter radio presets and clock time
- If the radio asks for a code, check your owner’s manual or contact Honda for the code
- Drive the car for 10–15 minutes to allow the transmission to relearn shift patterns
Tips for Preventing Future Check Engine Light Issues
Once the light is off, take steps to keep it that way:
- Use quality fuel: Stick to reputable gas stations to avoid contaminated fuel.
- Replace the gas cap properly: Always tighten it until it clicks.
- Follow the maintenance schedule: Regular oil changes, air filter replacements, and spark plug checks can prevent many issues.
- Address warning signs early: If you notice rough idling, reduced fuel economy, or strange noises, get them checked before the light comes on.
- Keep an OBD2 scanner handy: A basic scanner costs under $30 and can save you time and money in the long run.
When to See a Professional
While many check engine light issues can be handled at home, some situations require a professional mechanic:
- You’re unable to read or interpret the trouble code
- The repair involves complex components (e.g., catalytic converter, fuel injectors)
- The light flashes (indicating a severe misfire that can damage the engine)
- You’ve tried resetting the light multiple times and it keeps returning
A certified Honda technician has access to advanced diagnostic tools and can perform a thorough inspection.
