Before resetting the engine light, you must understand why it’s on. The check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your car’s onboard diagnostic system. When the computer detects a problem with the engine, emissions, or fuel system, it triggers the light to alert you.
In the 2013 Ford Standard Fiesta, the most common causes include:
– Loose or faulty gas cap
– Oxygen (O2) sensor failure
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Catalytic converter inefficiency
– Exhaust gas recirculation (EGR) valve malfunction
Some of these issues are minor and inexpensive to fix. Others, like catalytic converter failure, can cost hundreds. That’s why diagnosing the problem is the first and most important step.
Common Symptoms Alongside the Engine Light
Sometimes, the check engine light comes on without any noticeable symptoms. But in many cases, you’ll notice:
– Reduced fuel efficiency
– Rough idling or stalling
– Hesitation during acceleration
– Engine misfires
– Unusual smells from the exhaust
If you experience any of these, it’s a sign that the issue may be more serious. Don’t ignore them—even if the light seems to go away on its own.
Why You Shouldn’t Reset the Light Immediately
Many people make the mistake of resetting the engine light as soon as it appears, hoping it’ll stay off. But this is risky. If the underlying problem isn’t fixed, the light will likely return—and the issue could worsen.
For example, a loose gas cap might trigger the light. Tightening it could resolve the issue, and the light may turn off on its own after a few drive cycles. But if the problem is a failing oxygen sensor, resetting the light won’t fix the sensor. You’ll just be driving with a hidden issue that could damage your catalytic converter over time.
So, always diagnose first. Then repair. Then reset.
Tools You’ll Need to Reset the Engine Light
To reset the engine light on your 2013 Ford Standard Fiesta, you’ll need a few basic tools. The good news? Most are affordable and easy to find.
OBD2 Scanner (Recommended)
An OBD2 (On-Board Diagnostics) scanner is the best tool for the job. It plugs into your car’s diagnostic port and reads trouble codes stored in the engine control unit (ECU). These codes tell you exactly what’s wrong.
For the 2013 Fiesta, any standard OBD2 scanner will work. You don’t need a Ford-specific tool. Popular options include:
– BlueDriver Bluetooth Scanner (connects to your phone)
– Ancel AD310 (budget-friendly and reliable)
– Foxwell NT301 (great for beginners)
These scanners cost between $30 and $100 and can save you hundreds in diagnostic fees.
Basic Hand Tools
If you’re using a manual reset method, you’ll need:
– A wrench or socket set (to disconnect the battery)
– A screwdriver (for accessing the gas cap or fuse box)
– A flashlight (to see under the dashboard)
Owner’s Manual
Your 2013 Ford Fiesta owner’s manual contains valuable information about the check engine light, fuse locations, and reset procedures. Keep it handy.
Step-by-Step: How to Reset the Engine Light Using an OBD2 Scanner
Using an OBD2 scanner is the most accurate and reliable way to reset the engine light. Here’s how to do it safely and correctly.
Step 1: Locate the OBD2 Port
The OBD2 port in the 2013 Ford Standard Fiesta is located under the dashboard, near the driver’s side footwell. It’s a 16-pin connector, usually black or gray, and shaped like a trapezoid.
To find it:
– Sit in the driver’s seat
– Look down near the pedals
– You should see the port tucked behind a small panel or exposed
If you can’t find it, consult your owner’s manual. Some models may have it slightly to the left or right.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition completely. Then plug the OBD2 scanner into the port. Make sure it’s fully inserted—there should be a snug fit.
Step 3: Turn the Ignition to “On”
Do not start the engine. Turn the key to the “ON” position (or press the start button without pressing the brake). This powers up the car’s electrical system and allows the scanner to communicate with the ECU.
You’ll see the scanner light up and display a menu.
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to read the trouble codes. Most scanners have a “Read Codes” or “Scan” button.
The scanner will display one or more codes, such as:
– P0455 (Evaporative Emission Control System Leak)
– P0171 (System Too Lean)
– P0300 (Random/Multiple Cylinder Misfire)
Write down the codes. You can look them up online or use the scanner’s built-in database to understand what they mean.
Step 5: 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 P0300, inspect spark plugs and ignition coils
– If it’s P0133 (O2 sensor slow response), consider replacing the sensor
Only proceed to reset the light after the issue is resolved.
Step 6: Clear the Codes
On your OBD2 scanner, select “Clear Codes” or “Erase Codes.” Confirm the action when prompted.
The scanner will send a signal to the ECU to reset the check engine light. You should see a message like “Codes Cleared” or “Reset Successful.”
Step 7: Turn Off the Ignition and Unplug the Scanner
Turn the key back to “OFF” and unplug the scanner. Wait about 30 seconds before starting the car.
Step 8: Test Drive and Monitor
Start your Fiesta and take it for a short drive—about 10 to 15 minutes. This allows the car’s computer to run self-tests and confirm that the issue is resolved.
If the check engine light stays off, you’re good to go. If it comes back on, the problem may still exist. Recheck the codes and consider professional help.
Manual Reset Methods (And Their Limitations)
If you don’t have an OBD2 scanner, there are a few manual ways to reset the engine light. But be warned: these methods are less reliable and may not work for all issues.
Method 1: Disconnect the Battery
This is the most common DIY reset trick. It works by cutting power to the ECU, which clears stored codes.
Step-by-Step:
- Turn off the ignition and remove the key.
- Open the hood and locate the battery.
- Use a wrench to loosen the negative (-) terminal clamp.
- Disconnect the negative cable and wait 15 to 30 minutes.
- Reconnect the cable and tighten the clamp.
- Start the car and check if the light is off.
Important Notes:
– This method resets the ECU but doesn’t fix mechanical problems.
– It may also reset radio presets, clock, and adaptive transmission settings.
– Some newer Fiestas have battery management systems that may not allow a full reset this way.
Method 2: Tighten the Gas Cap
A loose or damaged gas cap is one of the top reasons for the check engine light in the 2013 Fiesta. The evaporative emissions system monitors for leaks, and a loose cap can trigger a P0455 code.
How to Fix:
- Turn off the engine.
- Open the fuel door and unscrew the gas cap.
- Inspect the cap for cracks or a damaged seal.
- Reinstall the cap and tighten it until you hear 3–5 clicks.
- Drive for 50–100 miles. The light may turn off on its own.
This is a free and easy fix—try it first before using other methods.
Method 3: Drive Cycle Reset
Sometimes, the engine light turns off after completing a “drive cycle”—a series of driving conditions that allow the car’s computer to retest systems.
Typical Drive Cycle for 2013 Fiesta:
- Start the engine and let it idle for 2–3 minutes.
- Drive at 30–40 mph for 5 minutes.
- Accelerate to 55 mph and cruise for 10 minutes.
- Decelerate without braking and let the car slow to 20 mph.
- Repeat 2–3 times.
After this, the ECU may clear the light if the issue was minor and resolved.
Troubleshooting: What to Do If the Light Won’t Reset
If you’ve tried resetting the engine light and it keeps coming back, don’t panic. Here’s how to troubleshoot.
The Light Returns Immediately
If the check engine light comes back on right after you reset it, the problem is likely still active. The ECU detects the same fault and re-triggers the light.
What to Do:
– Re-scan for codes using an OBD2 scanner
– Double-check your repair (e.g., is the gas cap really tight?)
– Inspect related components (wiring, sensors, hoses)
The Light Returns After a Few Days
This suggests an intermittent issue. For example, a loose connection or a sensor that fails under certain conditions.
What to Do:
– Keep a log of when the light appears (e.g., after rain, during acceleration)
– Check for loose wires or corrosion
– Consider professional diagnostics
You Can’t Read Codes
If your OBD2 scanner won’t connect or gives an error:
– Make sure the ignition is on (not running)
– Check the OBD2 port for dirt or damage
– Try a different scanner or visit an auto parts store (many offer free scans)
The Light Is Flashing
A flashing check engine light indicates a severe misfire that can damage the catalytic converter. This is an emergency.
What to Do:
– Pull over safely
– Turn off the engine
– Call a tow truck and avoid driving until repaired
