Before resetting the engine light, it’s crucial 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 Honda Element’s onboard diagnostics system (OBD2). It monitors various sensors and systems, including the engine, emissions, and fuel system.
When a problem is detected, the engine control unit (ECU) stores a diagnostic trouble code (DTC) and illuminates the light. The issue could range from minor to severe:
- Loose or faulty gas cap: This is one of the most common causes. A loose cap allows fuel vapors to escape, triggering the light.
- Oxygen sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A faulty sensor reduces fuel efficiency.
- Catalytic converter issues: A failing converter can cause poor performance and increased emissions.
- Mass airflow sensor problems: This sensor measures air entering the engine. If it’s dirty or broken, the engine may run rough.
- Spark plug or ignition coil failure: Misfires can damage the catalytic converter if left unchecked.
- Evaporative emissions system leak: A leak in the EVAP system can trigger the light even if it’s small.
Ignoring the light can lead to reduced fuel economy, increased emissions, and potential engine damage. That’s why diagnosing the issue is the first step—before resetting the light.
Tools You’ll Need
To reset the engine light on your Honda Element, you’ll need a few basic tools. The method you choose will determine what you need:
- OBD2 scanner: This is the most reliable tool. It plugs into the diagnostic port and reads trouble codes. Many affordable models are available online or at auto parts stores.
- Wrench or socket set: Needed if you plan to disconnect the battery.
- Safety gloves and glasses: Always protect yourself when working under the hood.
- Owner’s manual: Helpful for locating the diagnostic port and understanding your Element’s systems.
- Notepad and pen: To record trouble codes and repairs.
If you don’t own an OBD2 scanner, many auto parts stores (like AutoZone or O’Reilly) offer free code reading services. However, buying a basic scanner pays for itself after one or two uses.
Method 1: Using an OBD2 Scanner (Recommended)
The most accurate and recommended way to reset the engine light on your Honda Element is by using an OBD2 scanner. This method allows you to read the trouble codes, understand the problem, and clear the codes after repairs.
Step 1: Locate the OBD2 Port
The OBD2 port is usually located under the dashboard on the driver’s side. In the Honda Element, it’s typically found near the steering column, just below the knee panel. You may need to crouch down to see it clearly.
The port is a 16-pin connector, often black or gray, and shaped like a trapezoid. It’s standardized across all vehicles made after 1996, so it should be easy to identify.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s securely connected. Some scanners power on automatically when plugged in, while others require you to turn the ignition to the “ON” position (without starting the engine).
Wait a few seconds for the scanner to initialize and communicate with the vehicle’s ECU.
Step 3: Read the Trouble Codes
Once the scanner is ready, follow the on-screen prompts to read the diagnostic trouble codes (DTCs). Most scanners have a “Read Codes” or “Scan” button.
The scanner will display one or more codes, such as P0457 (loose gas cap) or P0301 (cylinder 1 misfire). Write down these codes—they’re essential for diagnosing the issue.
Many scanners also provide a brief description of each code. If yours doesn’t, you can look up the codes online using free resources like OBD-Codes.com or the scanner’s companion app.
Step 4: Fix the Underlying Problem
Before resetting the light, address the cause of the code. For example:
- If the code is P0457, check the gas cap. Tighten it or replace it if it’s cracked or worn.
- If it’s P0135 (oxygen sensor heater circuit), you may need to replace the sensor.
- For P0300 (random misfire), inspect spark plugs, ignition coils, and fuel injectors.
Fixing the problem ensures the light doesn’t come back immediately. If you’re unsure how to proceed, consult a repair manual or take your Element to a trusted mechanic.
Step 5: Clear the Codes and Reset the Light
After repairs, return to the OBD2 scanner. Select the “Clear Codes” or “Erase Codes” option. The scanner will send a command to the ECU to reset the check engine light.
Once cleared, the light should turn off. If it doesn’t, double-check that the scanner is properly connected and that the ignition is on.
Step 6: Verify the Reset
Start the engine and observe the dashboard. The check engine light should remain off. If it comes back on, the problem may not be fully resolved, or a new issue has arisen.
Take your Element for a short test drive to ensure everything runs smoothly. Some systems require a “drive cycle” to complete self-checks.
Method 2: Disconnecting the Battery
If you don’t have an OBD2 scanner, you can reset the engine light by disconnecting the battery. This method forces the ECU to reset, clearing temporary codes and turning off the light. However, it’s less precise than using a scanner and may not clear all stored data.
Step 1: Turn Off the Engine and Remove the Key
Make sure the engine is off and the key is removed from the ignition. This prevents electrical surges or damage during the process.
Step 2: Locate the Battery
Open the hood and locate the battery. In the Honda Element, it’s usually on the driver’s side, near the front of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench or socket to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery post to prevent accidental contact.
Important: Always disconnect the negative terminal first to avoid short circuits.
Step 4: Wait 10–15 Minutes
Leave the battery disconnected for at least 10 to 15 minutes. This allows the ECU to fully discharge and reset. Some sources recommend up to 30 minutes for older models.
During this time, the ECU loses power and clears its temporary memory, including the check engine light trigger.
Step 5: Reconnect the Battery
After waiting, reconnect the negative terminal and tighten the nut securely. Make sure the connection is snug to ensure proper electrical flow.
Step 6: Start the Engine
Turn the ignition to the “ON” position and wait a few seconds. Then start the engine. The check engine light should be off.
If the light remains on, the issue may still exist, or the ECU hasn’t fully reset. In some cases, the light may take a few drive cycles to turn off.
Method 3: Driving to Reset the Light
In some cases, the engine light may turn off on its own after the problem is fixed—especially if it was a minor issue like a loose gas cap. This is known as a “drive cycle reset.”
A drive cycle is a specific pattern of driving that allows the vehicle’s onboard computer to run self-diagnostics. Once all systems pass, the light may turn off automatically.
How to Complete a Drive Cycle
While drive cycles vary by model, a typical Honda Element drive cycle includes:
- Cold start: Let the engine cool overnight, then start it.
- Idle for 2–3 minutes to warm up.
- Drive at 30–40 mph for 5–10 minutes.
- Accelerate to 55–60 mph and maintain speed for 10–15 minutes.
- Decelerate and come to a complete stop.
- Repeat the cycle 2–3 times.
After completing the drive cycle, check if the light is off. This method works best for emissions-related codes that don’t require immediate attention.
Troubleshooting Common Issues
Even after resetting the engine light, you may encounter problems. Here’s how to troubleshoot:
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 and address the root cause.
Scanner Won’t Connect
Ensure the ignition is on (but engine off) and the scanner is properly plugged in. Try a different scanner or check for blown fuses related to the OBD2 system.
Battery Disconnection Didn’t Work
Some newer vehicles store codes in non-volatile memory, meaning they aren’t cleared by disconnecting the battery. In these cases, an OBD2 scanner is required.
Other Warning Lights Appear
Resetting the engine light may trigger other systems to re-check. If the ABS or airbag light comes on, it could indicate a separate issue. Consult a mechanic if multiple lights appear.
Tips to Prevent the Engine Light from Coming Back
Once you’ve reset the engine light, take steps to prevent it from returning:
- Regular maintenance: Follow the Honda Element’s maintenance schedule, including oil changes, air filter replacements, and spark plug checks.
- Check the gas cap: After every fill-up, make sure the cap is tight. Replace it every 5 years or if damaged.
- Use quality fuel: Low-quality or contaminated fuel can trigger sensors and cause misfires.
- Inspect hoses and belts: Cracked or loose vacuum hoses can cause EVAP leaks.
- Monitor driving habits: Avoid short trips that don’t allow the engine to fully warm up, as this can affect emissions systems.
When to See a Mechanic
While many engine light issues can be resolved at home, some require professional attention. Seek a mechanic if:
- The light is flashing (indicates a severe misfire that can damage the catalytic converter).
- You’re unable to read or clear the codes.
- The problem involves complex systems like the transmission or emissions.
- You’ve tried multiple fixes and the light keeps returning.
A certified Honda technician can perform advanced diagnostics and ensure your Element is in top condition.
