Before jumping into resetting the 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 vehicle’s onboard diagnostics system (OBD2). This system continuously monitors engine performance, emissions, and other critical functions.
When a sensor detects an anomaly—like a drop in fuel efficiency, a misfire, or an emissions leak—it sends a signal to the engine control unit (ECU). The ECU then triggers the check engine light to alert you.
Common causes in a 2013 Ford Escape include:
- A loose or damaged gas cap
- Faulty oxygen (O2) sensor
- Mass airflow (MAF) sensor issues
- Catalytic converter problems
- Spark plug or ignition coil failure
- Evaporative emissions system leaks
Ignoring the light can lead to reduced fuel economy, increased emissions, and even engine damage over time. That’s why diagnosing the issue is the first and most important step.
Step 1: Diagnose the Problem
You should never reset the check engine light without knowing what caused it. Doing so could mask a serious problem and lead to costly repairs down the road.
Use an OBD2 Scanner
The most reliable way to diagnose the issue is by using an OBD2 scanner. These devices plug into your vehicle’s OBD2 port—usually located under the dashboard near the steering column—and read the trouble codes stored in the ECU.
Here’s how to use one:
- Turn off the ignition and locate the OBD2 port (typically under the driver’s side dashboard).
- Plug in the OBD2 scanner.
- Turn the ignition to the “ON” position (but don’t start the engine).
- Follow the scanner’s instructions to retrieve the trouble codes.
- Write down the codes (e.g., P0420, P0171) and look them up online or in the scanner’s manual.
For example, code P0420 often indicates a catalytic converter issue, while P0171 suggests a lean fuel mixture. Knowing the code helps you determine the right fix.
Check the Gas Cap
Sometimes, the simplest fix is the right one. A loose, cracked, or missing gas cap can trigger the check engine light because it allows fuel vapors to escape, disrupting the evaporative emissions system.
To check:
- Turn off the engine and locate the gas cap.
- Remove it and inspect for cracks, wear, or damage.
- Reinstall it firmly until you hear it click.
- Drive the vehicle for a few days to see if the light turns off.
If the light goes off after tightening the cap, you’ve solved the problem—no reset needed.
Inspect for Obvious Issues
Look under the hood for visible problems:
- Check engine oil level and condition.
- Inspect air filter for dirt or blockages.
- Look for disconnected or damaged vacuum hoses.
- Listen for unusual engine noises like knocking or sputtering.
If you spot something obvious, address it before resetting the light.
Step 2: Fix the Underlying Issue
Once you’ve identified the problem, it’s time to fix it. Here are some common repairs for the 2013 Ford Escape:
Replace the Gas Cap
If the gas cap is damaged, replace it with a new one that meets OEM specifications. After installation, drive the vehicle for 50–100 miles. The light may turn off on its own.
Replace the Oxygen Sensor
Faulty O2 sensors are common in older vehicles. They monitor exhaust gases and help the ECU adjust the air-fuel mixture. Replacing a bad sensor can improve fuel economy and reduce emissions.
To replace:
- Locate the sensor (usually on the exhaust manifold or downpipe).
- Disconnect the electrical connector.
- Use an O2 sensor socket to remove the old sensor.
- Install the new sensor and reconnect the wiring.
- Clear the code and test drive.
Clean or Replace the Mass Airflow Sensor
A dirty MAF sensor can cause poor performance and trigger the check engine light. You can clean it with MAF sensor cleaner spray. If it’s damaged, replace it.
Address Ignition System Problems
Worn spark plugs or faulty ignition coils can cause misfires. Replace spark plugs every 60,000–100,000 miles and inspect coils for cracks or corrosion.
Repair Evaporative Emissions Leaks
Small leaks in the EVAP system—like cracked hoses or a faulty purge valve—can trigger codes. Use a smoke machine (or visit a mechanic) to locate the leak and replace damaged parts.
Step 3: Reset the Check Engine Light
After fixing the issue, you’ll want to reset the check engine light. There are several ways to do this, depending on your tools and comfort level.
Method 1: Use an OBD2 Scanner (Recommended)
This is the safest and most effective method. An OBD2 scanner not only reads codes but can also clear them.
Steps:
- Plug the scanner into the OBD2 port.
- Turn the ignition to “ON.”
- Navigate to the “Clear Codes” or “Erase DTCs” option.
- Confirm the action.
- Wait for the scanner to confirm the codes are cleared.
- Turn off the ignition and unplug the scanner.
After clearing, start the engine. The check engine light should be off. If it returns, the problem wasn’t fully resolved.
Tip: Some scanners also allow you to view live data and monitor sensor performance, which can help confirm the repair was successful.
Method 2: Drive the Vehicle (Natural Reset)
Modern vehicles like the 2013 Ford Escape can sometimes reset the check engine light on their own after the issue is fixed. This happens during a “drive cycle”—a series of driving conditions that allow the ECU to retest systems.
A typical drive cycle includes:
- Start the engine and let it idle for 2–3 minutes.
- Drive at 30–40 mph for 5 minutes.
- Accelerate to 55–60 mph and maintain speed for 10 minutes.
- Decelerate without braking and let the vehicle slow to 20 mph.
- Repeat the cycle 2–3 times.
After completing the drive cycle, the ECU may clear the codes and turn off the light. This process can take several days of normal driving.
Note: Not all codes can be cleared this way. Some require a scanner.
Method 3: Disconnect the Battery (Temporary Fix)
Disconnecting the battery can reset the ECU and clear the check engine light. However, this method has drawbacks and should be used cautiously.
Steps:
- Turn off the engine and remove the key.
- Open the hood and locate the battery.
- Use a wrench to loosen the negative (-) terminal clamp.
- Remove the negative cable and wait 15–30 minutes.
- Reconnect the cable and tighten the clamp.
- Start the engine and check if the light is off.
Why wait 15–30 minutes? The ECU needs time to discharge and reset. Shorter waits may not fully clear the memory.
Drawbacks:
- Resets radio presets, clock, and seat/mirror settings.
- May not clear all trouble codes, especially pending or permanent ones.
- Can trigger other warning lights (like ABS or airbag) temporarily.
This method is best used as a last resort or when you don’t have a scanner.
Method 4: Use the Ford Escape’s Built-In Reset (If Available)
Some Ford models have a hidden menu that allows you to reset certain systems. However, the 2013 Escape does not have a direct “reset check engine light” option in the dashboard menu. Attempting to access hidden menus can cause unintended issues, so this method is not recommended.
Stick to the OBD2 scanner or battery disconnection methods for safety.
Troubleshooting Common Issues
Even after resetting the light, problems can persist. Here’s how to handle common scenarios.
The Light Comes Back On
If the check engine light returns after resetting, the underlying issue wasn’t fixed. Possible reasons:
- The repair was incomplete (e.g., new sensor not properly installed).
- There’s a secondary issue you didn’t detect.
- The ECU hasn’t completed its self-tests yet.
Solution: Re-scan for codes and double-check your work. If you’re unsure, consult a mechanic.
The Light Flashes Instead of Staying Solid
A flashing check engine light indicates a severe problem, such as a major misfire that could damage the catalytic converter. This requires immediate attention.
Do not drive the vehicle. Have it towed to a repair shop.
The Scanner Won’t Clear the Codes
Some codes are “permanent” and can’t be cleared until the vehicle passes a full drive cycle. Others may require multiple attempts.
Try:
- Ensuring the ignition is on but the engine is off.
- Using a different scanner.
- Waiting 24 hours and trying again.
Battery Disconnection Causes Other Problems
After reconnecting the battery, you might notice:
- Radio asks for a code (check your owner’s manual for the reset code).
- Power windows or seats don’t work (reinitialize them by holding the switch up/down for 5 seconds).
- Check engine light returns immediately (indicates an ongoing issue).
These are usually temporary and resolve after driving.
Preventing Future Check Engine Light Issues
An ounce of prevention is worth a pound of cure. Keep your 2013 Ford Escape running smoothly with these tips:
Follow the Maintenance Schedule
Refer to your owner’s manual for recommended service intervals. Key items include:
- 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.
Use Quality Fuel and Additives
Fill up at reputable stations and consider using a fuel injector cleaner every 3,000–5,000 miles to prevent carbon buildup.
Inspect Hoses and Belts Regularly
Look for cracks, leaks, or wear in vacuum hoses and serpentine belts. Replace as needed.
Don’t Ignore Minor Symptoms
Rough idling, reduced power, or poor fuel economy can be early signs of trouble. Address them before they trigger the check engine light.
Keep the Gas Cap Tight
Always tighten the gas cap until it clicks. Make it a habit after every fill-up.
When to See a Mechanic
