Before you think about resetting the light, it’s crucial to understand why it came on in the first place. The check engine light is part of your Honda Pilot’s onboard diagnostic system (OBD2), which monitors engine performance, emissions, and other critical systems. When something goes wrong—like a sensor failure, fuel system issue, or emissions problem—the computer stores a trouble code and triggers the light.
Common causes include:
– A loose or faulty gas cap
– Oxygen (O2) sensor failure
– Catalytic converter problems
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Exhaust gas recirculation (EGR) valve malfunction
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. So, while it might be tempting to just reset it and hope it doesn’t come back, that’s not a smart long-term strategy. Always diagnose the root cause first.
Method 1: Fix the Problem, Then Drive It Out
One of the simplest and most effective ways to reset the engine light on your Honda Pilot is to fix the underlying issue and let the vehicle’s computer clear the code on its own. This method works because modern OBD2 systems are designed to automatically clear trouble codes once the problem is resolved and the vehicle completes a series of self-tests called a “drive cycle.”
Step 1: Identify the Issue
Start by getting the trouble code read. You can do this at most auto parts stores (like AutoZone, O’Reilly, or Advance Auto Parts) for free. They’ll plug in a scanner, retrieve the code (e.g., P0420 or P0171), and give you a printout explaining what it means.
Alternatively, you can buy an inexpensive OBD2 scanner (around $20–$50) and read the code yourself. These plug into the OBD2 port—usually located under the dashboard on the driver’s side—and display the code on a screen.
Step 2: Fix the Problem
Once you know the code, research the fix. For example:
– Code P0455 (large EVAP leak) often means a loose gas cap. Tighten it or replace it if cracked.
– Code P0135 (O2 sensor heater circuit) may require replacing the oxygen sensor.
– Code P0301 (cylinder 1 misfire) could point to a bad spark plug or ignition coil.
Many of these repairs are manageable for DIYers with basic tools. Others may require a mechanic. Either way, fixing the issue is the first step.
Step 3: Complete a Drive Cycle
After the repair, your Honda Pilot needs to complete a drive cycle so the computer can verify that the problem is gone. A typical drive cycle includes:
– Starting the engine when cold
– Driving at varying speeds (city and highway)
– Accelerating and decelerating smoothly
– Letting the engine reach normal operating temperature
This process usually takes 30–60 minutes of mixed driving. Once the computer confirms all systems are working, it will automatically clear the trouble code and turn off the check engine light.
Tip: Be Patient
Don’t expect the light to turn off immediately after fixing the issue. The system needs time to run its tests. If the light doesn’t go off after a few days of normal driving, there may be another issue—or the drive cycle wasn’t completed properly.
Method 2: Use an OBD2 Scanner to Reset the Light
If you want to manually reset the engine light on your Honda Pilot, an OBD2 scanner is the best tool for the job. This method gives you full control and is especially useful if the light won’t clear on its own or if you’ve already fixed the problem but want immediate confirmation.
Step 1: Locate the OBD2 Port
In most Honda Pilots, the OBD2 port is located under the dashboard, near the driver’s left knee. It’s a 16-pin connector, usually black or gray, and may be behind a small cover. If you can’t find it, check your owner’s manual—it’s typically on page 300 or so.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s securely connected.
Step 3: Turn on the Ignition
Turn the key to the “ON” position (but don’t start the engine). This powers up the vehicle’s computer and allows the scanner to communicate with it.
Step 4: Read the Codes
Follow the scanner’s instructions to read the trouble codes. Most scanners have a “Read” or “Scan” button. The device will display one or more codes (e.g., P0420). Write them down or take a photo for reference.
Step 5: Clear the Codes
Once you’ve reviewed the codes, look for a “Clear” or “Erase” option on the scanner. Select it to reset the check engine light. The scanner will confirm that the codes have been cleared.
Step 6: Turn Off the Ignition and Unplug
Turn off the ignition, unplug the scanner, and start the engine. The check engine light should be off. If it comes back on, the problem hasn’t been fixed.
Tip: Use a Quality Scanner
While basic scanners work for clearing codes, consider investing in a mid-range model (like the BlueDriver or Innova 3160) that can also monitor live data, check emissions readiness, and provide repair suggestions.
Method 3: Disconnect the Battery (Last Resort)
Disconnecting the battery is a traditional method for resetting the check engine light, but it’s not recommended as a first choice. Why? Because it resets more than just the engine light—it also clears radio presets, climate control settings, and adaptive transmission learning. In some cases, it can even trigger new warning lights or require a relearn procedure.
That said, if you don’t have a scanner and need a quick reset, here’s how to do it safely.
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is off and the key is out of the ignition.
Step 2: Locate the Battery
Open the hood and find the 12-volt battery. In the Honda Pilot, it’s usually on the driver’s side, near the front of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench (usually 10mm) to loosen the nut on the negative (-) battery terminal. Remove the cable and tuck it away so it doesn’t touch the terminal.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer to fully reset. Some experts recommend up to 30 minutes for older models.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure it’s snug but don’t overtighten.
Step 6: Start the Engine
Turn the key and start the engine. The check engine light should be off. If it returns, the issue persists.
Tip: Reset Radio and Clock
After reconnecting the battery, you may need to reset the radio presets and clock. Check your owner’s manual for instructions.
Method 4: Use the Honda Maintenance Minder (If Applicable)
Some newer Honda Pilots (especially 2016 and later) use a Maintenance Minder system that tracks service intervals and can sometimes interact with the check engine light. While this system doesn’t directly reset the engine light, it can help you stay on top of maintenance that prevents issues.
For example, if the Maintenance Minder shows code B13 (oil change and tire rotation), completing that service may resolve a related issue that triggered the light.
To reset the Maintenance Minder:
– Turn the ignition to “ON”
– Press the “Select/Reset” button on the instrument panel until the maintenance code flashes
– Hold the button for 10 seconds until the code resets
This won’t clear the check engine light, but it ensures your vehicle is properly maintained—which reduces the chance of future warnings.
Troubleshooting Common Issues
Even after following these steps, you might run into problems. Here’s how to handle common scenarios.
The Light Comes Back On
If the check engine light returns after resetting, the underlying issue hasn’t been fixed. Use an OBD2 scanner to read the new code and address the root cause. Don’t keep resetting the light without fixing the problem—this can lead to bigger issues down the road.
The Light Won’t Clear After a Repair
Sometimes, even after a repair, the light stays on. This could mean:
– The drive cycle wasn’t completed properly
– The repair wasn’t done correctly
– There’s a secondary issue
Try driving the vehicle for a few days, following a proper drive cycle. If the light persists, recheck the repair or consult a mechanic.
The Scanner Won’t Connect
If your OBD2 scanner won’t communicate with the vehicle:
– Make sure the ignition is on
– Check that the scanner is compatible with your Honda Pilot (most are)
– Try a different scanner or visit an auto parts store for a free scan
Battery Disconnection Didn’t Work
If disconnecting the battery didn’t reset the light, the issue may be more complex. The vehicle’s computer may require a specific reset procedure, or the problem may be intermittent. In this case, a professional diagnostic is recommended.
Preventing Future Check Engine Light Issues
The best way to deal with the check engine light is to avoid it altogether. Here are some preventive tips:
Regular Maintenance
Follow the Honda Pilot maintenance schedule in your owner’s manual. This includes:
– Oil and filter changes every 5,000–7,500 miles
– Air filter replacement every 15,000–30,000 miles
– Spark plug replacement every 60,000–100,000 miles
– Fuel system cleaning every 30,000 miles
Check the Gas Cap
After every fill-up, make sure the gas cap is tight. A loose cap is one of the most common causes of the check engine light.
Use Quality Fuel
Fill up at reputable gas stations. Low-quality fuel can cause sensor issues and engine knock.
Monitor Driving Habits
Avoid aggressive driving, excessive idling, and overloading the vehicle. These habits can strain the engine and emissions system.
Listen to Your Vehicle
If you notice rough idling, poor acceleration, or strange noises, address them early. Small issues can escalate quickly.
When to See a Mechanic
While many check engine light issues can be handled at home, some require professional attention. See a mechanic if:
– The light is flashing (this indicates a severe misfire that can damage the catalytic converter)
– You’re unable to read or clear the code
– The problem involves complex components like the transmission or fuel injectors
– You’ve tried multiple fixes and the light keeps returning
A certified Honda technician has access to advanced diagnostic tools and factory service information, which can save you time and money in the long run.
