Before we dive into how to reset the light, it’s important to understand what it means when the check engine light illuminates. Unlike other dashboard warnings (like the oil pressure or battery light), the check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). This system continuously monitors engine performance, emissions, and various sensors.
When something goes outside normal operating parameters, the computer stores a diagnostic trouble code (DTC) and triggers the light. The 2013 Ford F150 uses a sophisticated OBD2 system that can detect issues ranging from minor to severe.
Common reasons the check engine light may come on include:
- A loose or missing gas cap
- Faulty oxygen (O2) sensor
- Misfiring engine cylinders
- Problems with the catalytic converter
- Mass airflow (MAF) sensor issues
- Exhaust gas recirculation (EGR) valve malfunction
- Spark plug or ignition coil failure
- Evaporative emissions system leaks
The light may appear as either a steady glow or a flashing signal. A steady light usually indicates a less urgent issue, while a flashing light suggests a serious problem—like engine misfire—that could damage the catalytic converter if ignored.
Important: Never assume the issue is minor. Even if your truck seems to be running fine, underlying problems can worsen over time and lead to reduced fuel efficiency, increased emissions, or engine damage.
Tools You’ll Need
To reset the check engine light on your 2013 Ford F150, you’ll need a few basic tools. The method you choose will determine what equipment is necessary.
For OBD2 Scanner Method (Recommended)
- OBD2 scanner (Bluetooth or wired)
- Smartphone or tablet (if using a Bluetooth scanner with an app)
- Access to the OBD2 port (usually under the dashboard)
For Battery Disconnection Method
- Wrench or socket set (typically 10mm)
- Safety gloves and glasses (optional but recommended)
- 10–15 minutes of time
Optional but Helpful
- Flashlight (to see the OBD2 port clearly)
- Notebook or phone to record trouble codes
- Owner’s manual (for reference)
Investing in a quality OBD2 scanner is highly recommended. Basic models start around $20 and can read and clear codes, while more advanced scanners offer live data, freeze frame information, and compatibility with Ford-specific systems. Popular brands include BlueDriver, FIXD, and Autel.
Method 1: Reset Using an OBD2 Scanner (Best Practice)
Using an OBD2 scanner is the most reliable and recommended way to reset the check engine light on your 2013 Ford F150. This method allows you to read the trouble codes, understand what’s causing the issue, and confirm that the problem has been resolved before clearing the light.
Step 1: Locate the OBD2 Port
The OBD2 port in your 2013 Ford F150 is typically located under the dashboard on the driver’s side. It’s a 16-pin connector, usually black or gray, and may be covered by a small flap or panel.
To find it:
- Sit in the driver’s seat and look down near the steering column.
- The port is often just below the steering wheel, near the fuse box or knee panel.
- You may need to crouch or use a flashlight to see it clearly.
If you can’t locate it, consult your owner’s manual or search online for “2013 Ford F150 OBD2 port location” with images for visual reference.
Step 2: Turn Off the Ignition
Before connecting the scanner, make sure the ignition is turned off. This prevents any electrical surges or communication errors between the scanner and the vehicle’s computer.
Do not start the engine at this point.
Step 3: Connect the OBD2 Scanner
Plug the OBD2 scanner into the port. It should fit snugly—there’s only one way it can go in, so don’t force it.
If you’re using a Bluetooth scanner:
- Plug it into the port.
- Turn on your smartphone or tablet.
- Open the companion app (e.g., BlueDriver, Torque Pro).
- Pair the scanner with your device via Bluetooth.
For wired scanners, simply connect the USB or cable to your device if required.
Step 4: Turn the Ignition to “On” (But Don’t Start the Engine)
Turn the key to the “ON” position (or press the start button without pressing the brake). This powers up the vehicle’s electrical systems and allows the scanner to communicate with the engine control unit (ECU).
The dashboard lights will illuminate, but the engine should remain off.
Step 5: Read the Trouble Codes
Once the scanner is connected and the ignition is on, follow the on-screen prompts to read the diagnostic trouble codes (DTCs).
Most scanners will have a button or menu option labeled “Read Codes,” “Scan,” or “DTC.”
The scanner will retrieve stored codes from the ECU. These codes are usually in the format “P0XXX,” such as P0420 (catalytic converter efficiency below threshold) or P0171 (system too lean).
Tip: Write down the codes or take a screenshot. This information is crucial for diagnosing the problem.
Step 6: Research the Codes
Use the scanner’s built-in code definitions or search online for the meaning of each code. Websites like OBD-Codes.com or the scanner’s app often provide detailed explanations.
For example:
- P0455: Large evaporative emission system leak (often a loose gas cap)
- P0300: Random/multiple cylinder misfire detected
- P0133: O2 sensor circuit slow response (bank 1, sensor 1)
Understanding the code helps you determine whether the issue is something you can fix yourself—like tightening the gas cap—or if it requires professional attention.
Step 7: Fix the Underlying Issue
Before resetting the light, address the root cause. For example:
- If the code is P0455, check and tighten the gas cap. Replace it if it’s cracked or worn.
- If it’s a misfire (P0300), inspect spark plugs, ignition coils, or fuel injectors.
- If it’s an O2 sensor issue, you may need to replace the sensor (a job for experienced DIYers or a mechanic).
Skipping this step and just clearing the code will likely result in the light returning within a few drive cycles.
Step 8: Clear the Codes
Once the issue is fixed, return to the scanner and select the option to “Clear Codes,” “Erase DTCs,” or “Reset MIL.”
The scanner will send a command to the ECU to turn off the check engine light and erase the stored trouble codes.
You should see a confirmation message like “Codes Cleared” or “Reset Successful.”
Step 9: Turn Off the Ignition and Disconnect the Scanner
Turn the key back to the “OFF” position and unplug the scanner from the OBD2 port.
Step 10: Start the Engine and Verify
Start your truck and check the dashboard. The check engine light should be off.
If it remains off after driving for a few minutes, the reset was successful.
Note: Some systems may take a short drive cycle to fully reset. We’ll cover drive cycles in more detail later.
Method 2: Reset by Disconnecting the Battery
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 the ECU. However, it’s considered a less precise approach and comes with some drawbacks.
Step 1: Turn Off the Engine and Remove the Key
Make sure the truck is completely off and the key is removed from the ignition.
Step 2: Locate the Battery
The battery in the 2013 Ford F150 is located under the hood, on the driver’s side. It’s a standard 12-volt lead-acid battery.
Step 3: Disconnect the Negative Terminal
Using a 10mm wrench or socket, loosen the nut on the negative (black) battery terminal. Carefully remove the cable and set it aside so it doesn’t touch the battery post.
Safety Tip: Always disconnect the negative terminal first to reduce the risk of short circuits.
Step 4: Wait 10–15 Minutes
Leave the battery disconnected for at least 10 to 15 minutes. This allows the ECU and other modules to fully discharge and reset.
Some sources recommend waiting up to 30 minutes for a complete reset, especially if you’re also trying to reset radio presets or other settings.
Step 5: Reconnect the Battery
Reattach the negative cable to the battery terminal and tighten the nut securely.
Step 6: Start the Engine
Turn the key and start the truck. The check engine light may flash briefly as the system reinitializes, but it should turn off after a few seconds.
Step 7: Drive the Vehicle
Take your truck for a short drive (10–15 minutes) to allow the onboard computer to complete its self-checks.
Drawbacks of Battery Disconnection
While this method can clear the check engine light, it has several downsides:
- Doesn’t diagnose the problem: You won’t know what caused the light in the first place.
- Resets other systems: Radio presets, clock, seat memory, and transmission learning may be lost.
- May not clear all codes: Some trouble codes are stored in non-volatile memory and won’t be erased by a simple power cut.
- Light may return: If the underlying issue isn’t fixed, the light will come back on.
For these reasons, the OBD2 scanner method is strongly preferred.
Method 3: Drive Cycle Reset (Natural Clearing)
In some cases, the check engine light may turn off on its own after the problem is fixed—without any manual reset. This happens when the vehicle’s onboard computer completes a “drive cycle” and confirms that all systems are operating normally.
A drive cycle is a specific sequence of driving conditions that allows the ECU to test various emissions and engine systems.
What Is a Drive Cycle?
A typical drive cycle for a 2013 Ford F150 might include:
- Cold start (engine off for at least 8 hours)
- Idle for 2–3 minutes
- Drive at 30–40 mph for 5 minutes
- Accelerate to 55–60 mph and cruise for 10 minutes
- Decelerate without braking (coast in gear)
- Stop and idle for 2 minutes
The exact sequence varies by manufacturer and model year. Ford’s drive cycle requirements are designed to test oxygen sensors, catalytic converter efficiency, evaporative emissions, and more.
How Long Does It Take?
If the issue is resolved, the check engine light may turn off after 1–3 complete drive cycles. However, this isn’t guaranteed—some codes require a manual reset.
When to Use This Method
This approach works best for minor issues like a loose gas cap that you’ve tightened. If the light was triggered by a temporary glitch, driving normally for a few days may clear it.
However, for persistent or serious codes, don’t rely on a drive cycle alone. Use an OBD2 scanner to confirm the fix and reset the light.
Troubleshooting Common Issues
Even after following the steps above, you might run into problems. Here’s how to handle common scenarios.
The Light Comes Back On After Reset
If the check engine light returns shortly after resetting, the underlying issue hasn’t been resolved. Possible causes:
- The problem is intermittent (e.g., a failing sensor)
- The repair was incomplete or incorrect
- Multiple issues are present
Solution: Re-scan the vehicle with an OBD2 scanner to see if new or the same codes appear. Consult a mechanic if you’re unable to diagnose the issue.
Scanner Won’t Connect
If your OBD2 scanner fails to communicate with the truck:
- Ensure the ignition is in the “ON” position.
- Check that the scanner is compatible with Ford vehicles.
- Try a different scanner or app.
- Inspect the OBD2 port for dirt, corrosion, or damage.
Battery Disconnection Didn’t Work
If disconnecting the battery didn’t clear the light:
- Wait longer (up to 30 minutes)
- Ensure both terminals were disconnected (some systems require both)
- Use an OBD2 scanner instead
Radio or Settings Reset After Battery Disconnect
This is normal. To restore settings:
- Reprogram radio presets
- Reset the clock
- Re-adjust seat and mirror positions (if equipped with memory)
Some vehicles may require a dealership or specialized tool to restore certain functions.
