Before jumping into reset methods, it’s important to understand what the check engine light actually means. Unlike brake or oil pressure warnings, the check engine light doesn’t always signal an emergency. However, it should never be ignored.
The light is part of your Honda Element’s onboard diagnostics system (OBD2), which monitors engine performance, emissions, and various sensors. When the system detects a problem—such as a misfire, emissions leak, or sensor failure—it stores a diagnostic trouble code (DTC) and illuminates the check engine light.
In the 2007 Honda Element, common triggers include:
– Loose or damaged gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Catalytic converter inefficiency
– Exhaust gas recirculation (EGR) valve malfunction
The light may flash or stay steady. A flashing light usually indicates a severe issue like a misfire that could damage the catalytic converter—this requires immediate attention. A steady light often means a less urgent but still important problem.
Why You Shouldn’t Just Reset the Light
Many drivers make the mistake of clearing the check engine light without addressing the root cause. This is like turning off a smoke alarm while your kitchen is on fire—it hides the problem but doesn’t fix it.
Resetting the light without repairs can lead to:
– The light returning within days or even hours
– Increased emissions and reduced fuel efficiency
– Potential damage to engine components
– Failed emissions tests (required in many states)
– Higher repair costs down the line
Always diagnose the issue first. Use an OBD2 scanner to read the trouble code, research what it means, and determine if it’s something you can fix yourself or if you need a professional.
Tools You’ll Need
Depending on the method you choose, you may need one or more of the following tools:
– OBD2 scanner (basic code reader or advanced diagnostic tool)
– Socket wrench or wrench set (for battery disconnect)
– Safety gloves and glasses
– Owner’s manual (for fuse box and battery location)
– Pen and paper (to note down trouble codes)
Most OBD2 scanners are affordable—basic models start around $20—and can be reused for future diagnostics. If you plan to work on your car regularly, investing in a reliable scanner is worth it.
Method 1: Using an OBD2 Scanner (Recommended)
The most accurate and reliable way to reset the check engine light on a 2007 Honda Element is by using an OBD2 scanner. This method allows you to read the trouble code, understand the problem, and clear the light after repairs.
Step 1: Locate the OBD2 Port
The OBD2 port in the 2007 Honda Element 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 easily accessible. You don’t need to remove any panels—just look down near your knees while seated in the driver’s seat.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s fully inserted. Some scanners power on automatically when connected; others require you to turn the ignition to the “ON” position (without starting the engine).
Step 3: Read the Trouble Code
Follow the scanner’s instructions to retrieve the diagnostic trouble code (DTC). Common codes for the 2007 Element include:
– P0420: Catalyst system efficiency below threshold
– P0171: System too lean (bank 1)
– P0300: Random/multiple cylinder misfire
– P0455: Large evaporative emission leak (often a loose gas cap)
Write down the code and use the scanner’s built-in database or an online resource like OBD-Codes.com to interpret it.
Step 4: Fix the Underlying Issue
Once you know the problem, take steps to fix it. For example:
– If the code is P0455, check and tighten the gas cap.
– If it’s P0171, inspect for vacuum leaks or clean the MAF sensor.
– If it’s P0300, check spark plugs and ignition coils.
After repairs, clear the code using the scanner’s “Clear Codes” or “Erase DTC” function. The check engine light should turn off immediately.
Step 5: Verify the Fix
Drive the vehicle for a few days and monitor the light. If it stays off, the problem is likely resolved. If it returns, there may be a deeper issue requiring further diagnosis.
Method 2: Battery Disconnect (Manual Reset)
If you don’t have an OBD2 scanner, you can reset the check engine light by disconnecting the battery. This method forces the engine control unit (ECU) to reset, clearing stored codes and turning off the light. However, it’s less precise and may reset other systems.
Step 1: Turn Off the Engine and Remove Keys
Make sure the vehicle is off and the keys are out of the ignition. This prevents electrical surges or damage during the process.
Step 2: Locate the Battery
The battery in the 2007 Honda Element is under the hood 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 or socket to loosen the nut on the negative (black) battery cable. Carefully remove the cable and tuck it away from the battery terminal so it doesn’t accidentally reconnect.
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 recommend waiting 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: Start the Vehicle
Turn the ignition to “ON” and wait a few seconds. Then start the engine. The check engine light should be off. If it returns immediately, the problem wasn’t fixed.
Important Notes
– Disconnecting the battery may reset other systems, including the radio presets, clock, and power window settings.
– Some vehicles require a radio code to reactivate the stereo—check your owner’s manual.
– This method doesn’t guarantee the light won’t return if the issue persists.
Method 3: Driving Cycle (Automatic Reset)
After fixing the problem, the 2007 Honda Element may automatically reset the check engine light through a process called a “driving cycle.” This is a series of driving conditions that allow the onboard computer to retest systems and confirm repairs.
What Is a Driving Cycle?
A driving cycle is a specific pattern of driving that includes:
– Cold start (engine off for at least 8 hours)
– Idling for 2–3 minutes
– Accelerating to highway speeds (55–65 mph)
– Maintaining steady speed for 5–10 minutes
– Decelerating and stopping
The ECU monitors sensors during this cycle. If no faults are detected, it clears the trouble code and turns off the check engine light.
How to Perform a Driving Cycle
1. Start the engine after it’s been off overnight (cold start).
2. Let it idle for 2–3 minutes.
3. Drive at 30–40 mph for 5 minutes.
4. Accelerate to 55–65 mph and maintain speed for 10 minutes.
5. Slow down and stop. Repeat if needed.
Complete the cycle 2–3 times over a few days. The light should turn off if the issue is resolved.
Limitations
– Not all codes can be cleared this way—some require a scanner.
– If the light returns, the problem may still exist.
– Emissions monitors must complete before the light resets.
Troubleshooting Common Issues
Even after resetting the light, you may run into problems. Here’s how to handle common scenarios:
Check Engine Light Comes Back On
If the light returns shortly after reset, the original issue wasn’t fully fixed. Recheck the trouble code and inspect related components. For example, a P0420 code might require a new catalytic converter, not just a sensor replacement.
Radio or Clock Resets After Battery Disconnect
This is normal. Re-enter your radio presets and set the clock. If your radio asks for a code, consult the owner’s manual or contact a Honda dealer.
Scanner Won’t Connect
Ensure the ignition is in the “ON” position. Check that the OBD2 port is clean and undamaged. Try a different scanner if possible.
No Codes Found but Light Is On
Some scanners can’t read pending or manufacturer-specific codes. Use a more advanced scanner or visit a mechanic.
Light Flashes While Driving
This indicates a severe misfire. Pull over safely, turn off the engine, and call for assistance. Driving with a flashing light can damage the catalytic converter.
Preventing Future Check Engine Lights
The best way to avoid check engine lights is through regular maintenance. Here’s how to keep your 2007 Honda Element running smoothly:
– Replace the air filter every 15,000–30,000 miles.
– Change spark plugs every 60,000–100,000 miles.
– Use high-quality fuel and consider fuel system cleaners.
– Inspect and tighten the gas cap after every fill-up.
– Check for loose hoses or vacuum leaks during oil changes.
