Before you reset the engine light, it’s crucial to understand why it turned 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). When the system detects a problem with the engine, emissions, or related components, it triggers the light to alert you.
In the 2013 Ford Taurus, common causes include:
- Loose or faulty gas cap: This is one of the most frequent culprits. If the cap isn’t tightened properly after refueling, fuel vapors can escape, triggering the light.
- Oxygen sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A faulty sensor can reduce fuel efficiency and increase emissions.
- Catalytic converter issues: Over time, the catalytic converter can become clogged or damaged, leading to poor performance and emissions problems.
- Mass airflow (MAF) sensor problems: This sensor measures how much air enters the engine. If it’s dirty or malfunctioning, it can cause rough idling or poor acceleration.
- Spark plug or ignition coil failure: Worn spark plugs or faulty coils can cause misfires, which the OBD2 system will detect.
- Evaporative emissions system leaks: Small leaks in the fuel vapor system can trigger the light even if they’re hard to detect.
Ignoring the check engine light can lead to reduced fuel economy, increased emissions, and even engine damage over time. That’s why it’s important to diagnose the issue before resetting the light.
Method 1: Using an OBD2 Scanner (Recommended)
The most accurate and safest way to reset the engine light in your 2013 Ford Taurus is by using an OBD2 scanner. This handheld device plugs into your car’s diagnostic port and reads trouble codes stored in the vehicle’s computer. Once you’ve addressed the underlying issue, the scanner can clear the codes and turn off the light.
Step 1: Locate the OBD2 Port
In the 2013 Ford Taurus, the OBD2 port is typically located under the dashboard on the driver’s side. You’ll find it near the steering column, usually within easy reach. It’s a 16-pin connector that looks like a trapezoid-shaped plug. If you’re having trouble finding it, check just below the steering wheel or behind a small panel.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure the connection is secure. Some scanners require you to turn the ignition to the “ON” position (without starting the engine) to power up. Others may have their own battery.
Step 3: Read the Trouble Codes
Follow the scanner’s instructions to read the diagnostic trouble codes (DTCs). These codes—like P0455 (large evaporative leak) or P0171 (system too lean)—will tell you exactly what’s wrong. Write them down or take a photo for reference.
Step 4: Fix the Underlying Issue
Before resetting the light, fix the problem. For example:
– If the code points to a loose gas cap, tighten it or replace it.
– If it’s an oxygen sensor, you may need to replace it (this often requires tools and mechanical skill).
– For a MAF sensor, cleaning it with MAF cleaner spray might solve the issue.
Step 5: Clear the Codes and Reset the Light
Once the issue is resolved, use the scanner’s “Clear Codes” or “Erase DTCs” function. The check engine light should turn off immediately. If it doesn’t, double-check that the problem is truly fixed.
Step 6: Test Drive and Monitor
Take your Taurus for a short drive—about 10–15 minutes—to allow the system to complete a drive cycle. This helps the car’s computer verify that the issue is resolved. If the light stays off, you’re good to go.
Method 2: Manual Reset by Disconnecting the Battery
If you don’t have an OBD2 scanner, you can reset the engine light by disconnecting the car battery. This method forces the vehicle’s computer to reset, clearing stored codes and turning off the light. However, it’s not always recommended because it can erase important settings.
Step 1: Turn Off the Ignition
Make sure the car is completely off. Remove the key from the ignition and wait a few minutes to ensure all systems are powered down.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2013 Ford Taurus, it’s usually on the driver’s side of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench (typically 10mm) to loosen the nut on the negative (-) battery terminal. Carefully remove the cable and tuck it away from the battery post so it doesn’t accidentally reconnect.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the car’s computer (ECU) to fully reset. Some experts recommend up to 30 minutes for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is firm to avoid electrical issues.
Step 6: Start the Car
Turn the ignition to “ON” and wait a few seconds. Then start the engine. The check engine light should be off. If it comes back on, the problem may still exist.
Important Notes on Battery Disconnection
- Radio and clock settings may reset: You may need to re-enter your radio presets, clock time, and navigation settings.
- Adaptive learning resets: The engine’s adaptive learning—such as fuel trim adjustments—will reset, which can cause temporary rough idling or poor performance for a few drives.
- Not always effective: Some modern systems retain codes even after battery disconnection, especially if the issue persists.
Method 3: Drive Cycle Reset (Natural Clearance)
Sometimes, the check engine light will turn off on its own after the problem is fixed—no tools needed. This is called a “drive cycle reset” and happens when the car’s computer runs a series of self-tests and confirms no faults are present.
How a Drive Cycle Works
The 2013 Ford Taurus performs various diagnostic checks during normal driving. These include monitoring the oxygen sensors, catalytic converter, evaporative system, and more. If all tests pass over multiple drive cycles, the computer will automatically clear the code and turn off the light.
Typical Drive Cycle for Ford Taurus
To help trigger a drive cycle, follow this pattern:
- Start the car cold (hasn’t been driven for at least 4 hours).
- 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 slowly without braking hard.
- Repeat this cycle 2–3 times over a few days.
After completing several drive cycles, the light may turn off naturally. This method is free and safe but can take time—sometimes up to a week.
Troubleshooting Common Issues
Even after resetting the engine light, you might run into problems. Here’s how to handle common scenarios:
The Light Comes Back On Immediately
If the check engine light returns right after resetting, the underlying issue hasn’t been fixed. For example:
– A loose gas cap wasn’t tightened properly.
– A faulty sensor is still malfunctioning.
– There’s an intermittent electrical issue.
Use an OBD2 scanner to read the new code and address the root cause.
The Light Flickers or Flashes
A flashing check engine light indicates a severe problem—usually a misfire that can damage the catalytic converter. Pull over safely, turn off the engine, and have the car towed to a mechanic. Continuing to drive can cause expensive damage.
The Car Runs Poorly After Reset
If your Taurus feels sluggish, stalls, or has poor fuel economy after a reset, the engine’s adaptive learning may need time to relearn. Drive normally for 50–100 miles. If issues persist, there may be an unresolved mechanical problem.
Radio or Clock Resets After Battery Disconnect
This is normal. Re-enter your radio presets and set the clock. Some models may require a security code to unlock the radio—check your owner’s manual.
OBD2 Scanner Won’t Connect
If your scanner doesn’t power up or connect:
– Ensure the ignition is in the “ON” position.
– Check that the OBD2 port isn’t damaged or corroded.
– Try a different scanner or have the port inspected.
Preventing Future Check Engine Light Issues
The best way to avoid resetting the engine light is to prevent it from coming on in the first place. Here are some proactive tips:
- Check the gas cap after every fill-up: Make sure it clicks when tightened. Replace it if it’s cracked or worn.
- Use quality fuel: Low-quality or contaminated fuel can trigger sensor issues.
- Follow the maintenance schedule: Replace spark plugs, air filters, and oxygen sensors as recommended (typically every 60,000–100,000 miles).
- Keep the engine clean: Regularly inspect for leaks, loose hoses, or damaged wiring.
- Address warning signs early: If you notice rough idling, poor acceleration, or decreased fuel economy, get it checked before the light comes on.
When to See a Mechanic
While many check engine light issues can be resolved at home, some problems require professional help. Visit a certified mechanic if:
- The light is flashing or stays on after multiple resets.
- You’re unable to read or interpret the trouble codes.
