Before we dive into how to reset the light, it’s important to understand why it came on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors various sensors and systems, including the engine, transmission, exhaust, and emissions controls.
When the system detects a problem—such as a loose gas cap, faulty oxygen sensor, or misfiring engine—it stores a trouble code and illuminates the check engine light. This doesn’t always mean your car is about to break down, but it does mean something needs attention.
Common causes in the 2014 Honda CR-V include:
– Loose or damaged gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Catalytic converter 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 it’s crucial to diagnose the issue before resetting the light.
Method 1: Using an OBD2 Scanner (Recommended)
The most reliable and safest way to reset the check engine light on your 2014 Honda CR-V is by using an OBD2 scanner. This tool reads the trouble codes stored in your vehicle’s computer, helps you understand what’s wrong, and allows you to clear the codes—effectively turning off the light.
Step 1: Purchase or Borrow an OBD2 Scanner
You can buy a basic OBD2 scanner for as little as $20–$30 online or at auto parts stores. Popular brands include BlueDriver, Autel, and Innova. Many auto parts stores (like AutoZone or O’Reilly) also offer free code reading services, though they may not let you clear the codes yourself.
Make sure the scanner is compatible with OBD2 systems—all vehicles made after 1996, including your 2014 CR-V, use this standard.
Step 2: Locate the OBD2 Port
In the 2014 Honda CR-V, the OBD2 port is 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.
To access it:
– Sit in the driver’s seat and look down near your left knee.
– You may need to crouch or use a flashlight to spot it.
– Gently pull the connector out—no tools required.
Step 3: Plug in the Scanner and Turn on the Ignition
Insert the OBD2 scanner into the port. Make sure it’s fully seated. Then, turn the ignition to the “ON” position—but don’t start the engine. This powers up the vehicle’s computer system so the scanner can communicate with it.
Most scanners will automatically detect the vehicle and display a menu. If not, follow the on-screen instructions to select your vehicle make, model, and year.
Step 4: Read the Trouble Codes
Navigate to the “Read Codes” or “Scan” option on the scanner. The device will retrieve any stored trouble codes from the computer. These codes are usually in the format P0XXX (e.g., P0420 for catalytic converter efficiency).
Write down the codes or take a photo for reference. You can then look them up online or use the scanner’s built-in database to understand what they mean.
For example:
– P0455: Large EVAP leak (often a loose gas cap)
– P0171: System too lean (could be a vacuum leak or MAF sensor issue)
– P0301: Cylinder 1 misfire (may indicate a bad spark plug or coil)
Step 5: Fix the Underlying Issue
Before resetting the light, address the problem. For instance:
– If the code is P0455, check and tighten the gas cap. Replace it if cracked or damaged.
– If it’s a misfire code, inspect spark plugs and ignition coils.
– For O2 sensor codes, consider replacing the sensor if it’s old or faulty.
Skipping this step means the light will likely come back on.
Step 6: Clear the Codes and Reset the Light
Once the issue is fixed, return to the scanner menu and select “Clear Codes” or “Erase Codes.” Confirm the action when prompted. The scanner will send a signal to the vehicle’s computer to delete the stored trouble codes and turn off the check engine light.
After clearing, turn off the ignition, wait 10–15 seconds, then turn it back on. The light should be off. If it’s still on, the problem may not be fully resolved, or the system hasn’t completed its self-check yet.
Step 7: Complete a Drive Cycle (If Needed)
Some systems require a “drive cycle” to confirm the fix. This is a series of driving conditions that allow the computer to retest emissions and engine functions.
For the 2014 CR-V, a typical drive cycle includes:
– Cold start (engine off for at least 8 hours)
– Drive at 30–40 mph for 5 minutes
– Accelerate to 55 mph and maintain speed for 10 minutes
– Decelerate to 20 mph without braking
– Stop and idle for 2 minutes
After completing the drive cycle, the computer will recheck systems. If everything passes, the light should stay off.
Method 2: Disconnecting the Battery (Alternative Method)
If you don’t have an OBD2 scanner, you can reset the check engine light by disconnecting the battery. This method forces the vehicle’s computer to reset by cutting power to its memory. However, it’s not as precise as using a scanner and comes with some drawbacks.
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is completely off. Remove the key from the ignition to prevent any electrical surges.
Step 2: Locate the Battery
In the 2014 Honda CR-V, the battery is in the engine compartment on the driver’s side. It’s a standard 12-volt lead-acid battery with positive (+) and negative (-) terminals.
Step 3: Disconnect the Negative Terminal
Use a wrench (usually 10mm) to loosen the nut on the negative (black) battery cable. Carefully remove the cable and set it aside, making sure it doesn’t touch the battery terminal.
Important: Always disconnect the negative terminal first to avoid short circuits.
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 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 firm to avoid electrical issues.
Step 6: Turn on the Ignition
Turn the ignition to the “ON” position (don’t start the engine yet). Wait a few seconds, then start the vehicle. The check engine light may flash briefly but should turn off after a few seconds.
If the light remains on, the issue may still exist, or the system hasn’t completed its self-check.
Potential Side Effects
Disconnecting the battery can reset more than just the check engine light. You may also lose:
– Radio presets and clock settings
– Seat and mirror memory (if equipped)
– Adaptive transmission learning (may cause rough shifting initially)
– Anti-theft system codes (rare, but possible)
To restore radio settings, you may need to enter a security code. Check your owner’s manual or look for a sticker in the glove box or under the hood.
Method 3: Using the Honda Maintenance Minder (Limited Use)
The 2014 Honda CR-V has a Maintenance Minder system that tracks service intervals. While it doesn’t directly reset the check engine light, it can help you stay on top of maintenance that might prevent future issues.
If your check engine light is related to routine maintenance (like an oil change or air filter replacement), completing the service and resetting the Maintenance Minder may help prevent the light from returning.
To reset the Maintenance Minder:
1. Turn the ignition to “ON” (do not start the engine).
2. Press the “Select/Reset” button on the instrument panel until the maintenance code (e.g., A1 or B12) appears.
3. Hold the button for 10 seconds until the code blinks.
4. Release and hold again for another 5 seconds until it resets to 100%.
This won’t clear the check engine light, but it ensures your vehicle is properly maintained—reducing the chance of future problems.
Troubleshooting Common Issues
Even after resetting the light, you may run into problems. Here’s how to handle common scenarios:
The Light Comes Back On Immediately
If the check engine light returns right after resetting, the underlying issue hasn’t been fixed. Use an OBD2 scanner to read the codes again. Common culprits include:
– A gas cap that wasn’t tightened properly
– A sensor that needs replacement
– An intermittent electrical issue
The Light Flashes While Driving
A flashing check engine light indicates a severe problem, such as a major misfire that could damage the catalytic converter. Pull over safely, turn off the engine, and have the vehicle towed to a mechanic.
