Why This Matters / Understanding the Problem

You’re driving your 2013 Ford Explorer, and suddenly, that pesky check engine light pops on. It might feel like a red alert, but it’s actually your car’s way of saying, “Hey, something’s not quite right—let’s check it out.” Whether it’s a loose gas cap or a deeper issue, ignoring it isn’t smart. That’s why learning the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer is more than just a quick fix—it’s about understanding your vehicle’s health and knowing when to act.

The check engine light (CEL), also known as the malfunction indicator lamp (MIL), is tied to your car’s onboard diagnostics (OBD-II) system. This system monitors everything from emissions to engine performance. When it detects a problem—even something small—it triggers the light and stores a diagnostic trouble code (DTC). The good news? Many issues are minor, and once fixed, the light can be reset. But here’s the catch: you shouldn’t reset it until you know what caused it.

Resetting the light without diagnosing the root cause is like silencing a smoke alarm without checking for fire. That’s why this guide doesn’t just show you how to turn the light off—it teaches you when and how to do it safely. Whether you’re prepping for a smog test, troubleshooting a recent repair, or just tired of seeing that yellow glow, the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer gives you the knowledge and tools to handle it like a pro.

What You Need

Before you dive in, gather these tools. Don’t worry—you don’t need a full garage setup. Most items are affordable or already in your toolbox.

• OBD-II scanner (code reader) – This is the most important tool. It reads the trouble codes and allows you to reset the light. Look for models compatible with Ford vehicles (like the BlueDriver or Autel AL519). A basic $20–$30 model works for simple resets.
• Owner’s manual – Handy for checking fuse locations and dashboard warnings.
• 10mm socket and ratchet – For disconnecting the battery (optional method).
• Work gloves – Protect your hands when working near the battery or engine.
• Flashlight – Helps you see the OBD-II port, especially in dark garages.
• Notebook or phone – To write down any trouble codes before resetting.
• Gas cap (if loose or damaged) – A common cause of CEL. Keep a spare on hand.

Pro Tip: If you don’t have an OBD-II scanner, most auto parts stores (like AutoZone or O’Reilly) offer free code reading and even free resets. Just walk in—no purchase needed.

Now, let’s get into the step-by-step process. Whether you use a scanner or the battery method, this 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer ensures you do it right.

Step-by-Step Guide to 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer

Step 1: Diagnose the Problem First—Don’t Skip This!

Before you even think about resetting the light, find out why it’s on. The OBD-II system stores a code that tells you exactly what’s wrong. Skipping this step is the #1 mistake people make.

Start by plugging your OBD-II scanner into the port. In the 2013 Ford Explorer, this port is located under the dashboard on the driver’s side—just to the left of the steering column, near the hood release. It’s a 16-pin connector, and it’s usually easy to spot.

Turn the ignition to “ON” (but don’t start the engine). Power on the scanner and follow the on-screen prompts to “Read Codes.” The scanner will display a code like P0455 (large evaporative leak) or P0301 (cylinder 1 misfire). Write it down.

Warning: If the code indicates a serious issue—like a misfire, catalytic converter problem, or oxygen sensor failure—don’t reset the light yet. Fix the problem first. Driving with these issues can damage your engine or fail emissions tests.

For example, if the code is P0457 (gas cap not tightened), tighten or replace the cap. If it’s P0420 (catalyst efficiency), you may need professional help. The 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer emphasizes diagnosis first—reset second.

Step 2: Fix the Underlying Issue

Now that you know the cause, fix it. Here are common fixes for frequent 2013 Explorer codes:

• Loose gas cap: Tighten it until you hear 3–4 clicks. If it’s cracked or worn, replace it.
• Oxygen sensor issue: This requires replacement. Use a Bosch 15703 or Motorcraft DY1113 for OEM fit.
• EVAP system leak: Check hoses near the gas tank for cracks. Replace if damaged.
• Spark plug misfire: Replace spark plugs (NGK or Motorcraft recommended). Use a torque wrench to avoid over-tightening.
• Mass airflow (MAF) sensor dirty: Clean with MAF-safe cleaner spray—don’t touch the sensor wire.

After fixing the issue, drive the car for 50–100 miles. The OBD-II system needs time to run its self-tests. This is called the drive cycle. If the problem is truly fixed, the light may turn off on its own. But if it’s still on, proceed to the reset.

Remember: The 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer isn’t about tricking the system—it’s about confirming the fix and resetting when appropriate.

Step 3: Use the OBD-II Scanner to Reset the Light

This is the safest and most reliable method. It clears the code and resets all readiness monitors.

1. Plug the OBD-II scanner into the port.
2. Turn the ignition to “ON” (engine off).
3. Navigate to “Clear Codes” or “Erase DTCs” on the scanner.
4. Confirm the reset when prompted.
5. Wait 10–15 seconds. The scanner will confirm the codes are erased.

After the reset, the check engine light should turn off immediately. If it flickers or comes back on, that means the problem wasn’t fully resolved—or the system hasn’t completed its self-checks yet.

Now, start the engine and let it idle for 2–3 minutes. Drive normally for 10–15 minutes, including some highway speeds if possible. This helps the car’s computer re-learn sensor patterns and complete readiness tests.

Pro Tip: Use your scanner to check “Readiness Monitors” after resetting. If all monitors show “Complete,” your car is ready for an emissions test. If some are “Incomplete,” drive a bit more—avoid short trips.

This method is ideal because it doesn’t affect your car’s battery or electrical system. It’s the preferred way in the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer.

Step 4: Alternative Method—Disconnect the Battery (Use with Caution)

If you don’t have a scanner, you can try disconnecting the battery. But be warned: this method has downsides.

1. Turn off the engine and remove the key.
2. Open the hood and locate the battery (driver’s side, front of engine bay).
3. Use a 10mm wrench to loosen the negative terminal (marked “-” or black). Remove the cable.
4. Wait at least 15 minutes. This gives the car’s computer time to fully discharge and reset.
5. Reconnect the negative cable and tighten it securely.
6. Start the engine. The check engine light may flash for a few seconds, then turn off.

However, this method does not clear the trouble code from memory permanently. It only resets the light temporarily. The code may return after a few drive cycles if the issue persists. Plus, you’ll lose:

• Radio presets
• Clock settings
• Memory seat positions (if equipped)
• ECU learning data (may cause rough idle for a few days)

Warning: Never disconnect the battery while the engine is running. This can damage the alternator and ECU. Always remove the negative terminal first.

Only use this method if you’re in a pinch or waiting to buy a scanner. For long-term reliability, the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer recommends the OBD-II method.

Step 5: Verify the Reset Worked

After resetting, don’t assume it’s done. You need to verify the light stays off and the problem is truly fixed.

• Drive for at least 50 miles over a few days.
• Include city, highway, and idle time to complete drive cycles.
• Check the dashboard: if the light returns, the issue wasn’t fixed.
• Use your scanner again to read codes. If none appear, you’re good.

For emissions testing, most states require all readiness monitors to be “Complete.” Your scanner can check this. If monitors are incomplete, drive more—especially on highways with steady speeds.

Example: A friend of mine reset his Explorer’s light after replacing a gas cap. The light stayed off for a day, then came back. He scanned again and found P0456 (small EVAP leak). It turned out a hose near the charcoal canister was cracked. Only after fixing that did the light stay off permanently.

This step is crucial in the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer—because a reset without verification is just a guess.

Step 6: Prevent Future Check Engine Lights

Now that you’ve reset the light, keep it off. Prevention is easier than fixing.

• Tighten the gas cap properly after every fill-up. Listen for the clicks.
• Use quality fuel—avoid discount stations with high sulfur content.
• Follow the maintenance schedule in your owner’s manual. Replace spark plugs every 100,000 miles, oxygen sensors as needed.
• Clean the MAF sensor every 30,000 miles with a spray cleaner.
• Check for recalls—Ford issued several for 2013 Explorers, including transmission and engine issues. Visit NHTSA’s recall site and enter your VIN.

Also, consider installing a Bluetooth OBD-II adapter (like FIXD or BlueDriver). It connects to your phone and alerts you to codes in real time. You’ll know before the light even comes on.

This proactive approach is a key part of the 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer—because the best fix is preventing the problem in the first place.

Pro Tips & Common Mistakes to Avoid

Let’s face it—resetting the check engine light seems simple. But small mistakes can lead to big problems. Here’s what the pros know (and what you should too).

• Never reset without diagnosing. It’s like turning off a fire alarm without checking for smoke. The light may come back—and worse, you could damage your engine.
• Don’t use “code eraser” apps that skip diagnosis. Some cheap scanners let you clear codes without reading them. That’s dangerous. Always know the code first.
• Avoid the “three ignition cycles” myth. Some say turning the key on/off three times resets the light. This doesn’t work on modern cars like the 2013 Explorer. Only an OBD-II scan or battery disconnect does.
• Don’t disconnect the battery for minor issues. It’s overkill and causes data loss. Use a scanner instead.
• Don’t ignore readiness monitors. If you’re preparing for a smog check, make sure all monitors are “Complete.” Otherwise, the test will fail.
• Check for pending codes. Some scanners show “pending” codes—issues that haven’t triggered the light yet. Fix these early to avoid future lights.
• Use OEM or high-quality parts. Cheap oxygen sensors or spark plugs may cause new codes. Stick with Motorcraft, NGK, or Bosch.

Real-Life Example: A mechanic friend once had a customer who reset the light 10 times in a month. The code was P0304 (cylinder 4 misfire). Instead of replacing the spark plug, he kept clearing it. Eventually, the misfire damaged the catalytic converter—costing $1,200 to fix. Diagnosis first, reset second.

The 2026 Guide How to Reset Check Engine Light on 2013 Ford Explorer isn’t just about turning off a light—it’s about responsible car care.
