Before you reset the check engine light, it’s crucial to understand what it’s trying to tell you. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your Honda Element’s onboard diagnostics system (OBD2). When the vehicle’s computer detects a problem with the engine, emissions system, or other critical components, it triggers this warning.
The light can appear in two forms:
– Steady (solid) light: Indicates a minor issue, such as a loose gas cap or a failing oxygen sensor.
– Flashing light: Signals a severe problem, like engine misfire, which can damage the catalytic converter if ignored.
Common causes include:
– Loose or damaged gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Catalytic converter failure
– Exhaust gas recirculation (EGR) valve malfunction
Ignoring the light can reduce fuel efficiency, increase emissions, and even lead to engine damage. That’s why diagnosing the issue before resetting the light is so important.
Step 1: Diagnose the Problem
You should never reset the check engine light without first identifying and fixing the underlying issue. Resetting it prematurely is like turning off a fire alarm while the house is still burning—it doesn’t solve the problem.
Use an OBD2 Scanner
The most accurate way to diagnose the issue is with an OBD2 scanner. These devices plug into your Honda Element’s diagnostic port (usually located under the dashboard, near the steering column) and read the trouble codes stored in the vehicle’s computer.
Here’s how to use one:
1. Turn off the engine and locate the OBD2 port.
2. Plug in the scanner and turn the ignition to the “ON” position (do not start the engine).
3. Follow the scanner’s instructions to retrieve the diagnostic trouble codes (DTCs).
4. Write down the codes (e.g., P0420, P0171) and look them up online or in the scanner’s manual.
For example:
– P0420: Catalyst system efficiency below threshold
– P0171: System too lean (bank 1)
– P0300: Random/multiple cylinder misfire detected
These codes give you a clear starting point for repairs.
Check the Gas Cap
One of the most common—and easiest—fixes is a loose or damaged gas cap. Honda Elements are especially prone to this issue because the cap can wear out over time or simply not be tightened properly after refueling.
To check:
1. Turn off the engine and locate the gas cap.
2. Twist it counterclockwise to remove it.
3. Inspect the rubber seal for cracks or damage.
4. Reinstall it and tighten it until you hear three clicks.
After driving for a few days, the light may turn off on its own if the gas cap was the only issue.
Inspect Common Components
If the scanner shows a specific code, inspect the related component. For example:
– O2 sensor: Located in the exhaust system, it monitors oxygen levels. A faulty sensor can reduce fuel efficiency.
– MAF sensor: Measures airflow into the engine. Clean it with MAF cleaner if dirty.
– Spark plugs: Worn plugs can cause misfires. Replace them every 30,000–100,000 miles, depending on the type.
Step 2: Fix the Underlying Issue
Once you’ve identified the problem, it’s time to fix it. This step is non-negotiable—resetting the light without a repair will only cause it to return.
Replace Faulty Parts
If a component is damaged, replace it with a high-quality part. For example:
– Use a genuine Honda or reputable aftermarket O2 sensor.
– Replace spark plugs with the correct type (e.g., iridium or platinum) recommended for your Element’s engine.
Tighten or Replace the Gas Cap
If the gas cap is loose, tighten it properly. If it’s damaged, replace it with a new one. Honda recommends using OEM (original equipment manufacturer) caps for best results.
Clear Carbon Buildup
For issues like EGR valve clogging, use a carbon cleaner or have the valve professionally cleaned. Avoid cheap additives that can damage sensors.
Address Engine Misfires
Misfires can stem from bad spark plugs, ignition coils, or fuel injectors. Replace faulty coils and plugs, and consider cleaning fuel injectors with a quality cleaner.
Step 3: Choose a Reset Method
After fixing the issue, you can reset the check engine light. There are three main methods: using an OBD2 scanner, disconnecting the battery, or driving the vehicle to allow the system to reset automatically.
Method 1: Use an OBD2 Scanner (Recommended)
This is the most reliable and professional way to reset the light.
Steps:
1. Plug the OBD2 scanner into the diagnostic port.
2. Turn the ignition to “ON” (engine off).
3. Navigate to the “Clear Codes” or “Erase DTCs” option on the scanner.
4. Confirm the reset.
5. Turn off the ignition and unplug the scanner.
The check engine light should go off immediately. Start the engine to confirm it stays off.
Tip: Some scanners also allow you to view live data, freeze frame data, and monitor readiness monitors—useful for ensuring the repair was successful.
Method 2: Disconnect the Battery
This method forces the vehicle’s computer to reset by cutting power. It’s simple but has drawbacks.
Steps:
1. Turn off the engine and remove the key.
2. Open the hood and locate the battery.
3. Use a wrench to loosen the negative (-) terminal clamp.
4. Disconnect the negative cable and wait 15–30 minutes.
5. Reconnect the cable and tighten it securely.
Why wait? The vehicle’s computer needs time to discharge residual power. Skipping this step may not fully reset the system.
Note: Disconnecting the battery can reset other systems, such as the radio presets, clock, and anti-theft system. You may need to re-enter a radio code or reprogram key fobs.
Method 3: Drive the Vehicle (Automatic Reset)
In some cases, the check engine light will turn off on its own after the problem is fixed and the vehicle completes several drive cycles.
A drive cycle includes:
– Starting the engine when cold
– Driving at varying speeds
– Stopping and restarting the engine
The computer monitors sensors and systems during these cycles. If no errors are detected, it clears the codes and turns off the light.
This method can take 3–7 days of normal driving. It’s passive but effective for minor issues.
Step 4: Verify the Reset
After resetting the light, it’s important to confirm the issue is truly resolved.
Check the Dashboard
Start the engine and ensure the check engine light does not reappear. If it does, the problem persists.
Use the OBD2 Scanner Again
Plug in the scanner and check for any remaining codes. If none appear, the reset was successful.
Monitor Vehicle Performance
Pay attention to:
– Engine smoothness
– Fuel economy
– Exhaust smell or noise
If anything feels off, have the vehicle inspected.
Troubleshooting Common Issues
Even after a reset, problems can arise. Here’s how to handle them.
Check Engine Light Returns
If the light comes back, the original issue wasn’t fully resolved. Re-scan for codes and inspect the related components. For example, a P0420 code may indicate a failing catalytic converter, not just a faulty O2 sensor.
Radio or Clock Resets After Battery Disconnect
This is normal. Re-enter your radio presets and set the clock. If your Element has a security system, you may need to reprogram the key fob.
Scanner Won’t Connect
Ensure the ignition is on, the scanner is compatible with OBD2, and the port is clean. Try a different scanner if needed.
Light Flashes After Reset
A flashing light indicates a severe misfire. Stop driving immediately and have the vehicle towed to a mechanic. Continuing to drive can damage the catalytic converter.
Preventing Future Check Engine Light Issues
The best way to avoid resetting the light is to prevent it from coming on in the first place.
Follow the Maintenance Schedule
Honda recommends regular service intervals. For the Element, this includes:
– Oil changes every 5,000–7,500 miles
– Spark plug replacement every 100,000 miles (or sooner if using conventional plugs)
– Air filter replacement every 15,000–30,000 miles
– Fuel system cleaning every 30,000 miles
Use Quality Fuel and Parts
Fill up at reputable gas stations and use top-tier gasoline. Avoid cheap aftermarket parts that may not meet OEM standards.
Inspect the Gas Cap Regularly
Check the cap every few months for wear and ensure it’s tightened after every fill-up.
Address Warning Signs Early
If you notice rough idling, reduced power, or poor fuel economy, have the vehicle checked before the light comes on.
When to See a Mechanic
While many check engine light issues can be handled at home, some require professional attention.
Seek a mechanic if:
– The light is flashing
– You’re unsure of the diagnosis
– The problem involves the transmission, catalytic converter, or internal engine components
– The light returns repeatedly after reset
A certified Honda technician has specialized tools and knowledge to handle complex repairs.
