Before you reset the check engine light, it’s essential to understand what it means. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostic system (OBD2). When it illuminates, it means the computer has detected a problem that could affect emissions, fuel efficiency, or engine performance.
On the 2017 Ford Escape, the light can appear in two ways:
– Solid (steady) light: Indicates a minor issue, such as a loose gas cap or faulty sensor.
– Flashing light: Signals a serious problem, like an engine misfire, that requires immediate attention.
Ignoring a flashing light can lead to costly damage, especially to the catalytic converter. That’s why diagnosing the issue before resetting the light is critical.
The OBD2 system in your Escape stores trouble codes that correspond to specific problems. These codes can be read using a diagnostic scanner, which helps pinpoint the exact cause. Once the issue is fixed, the light can be reset—but only after confirming the repair was successful.
Why You Shouldn’t Just Reset the Light
Many drivers make the mistake of resetting the check engine light without fixing the underlying problem. This is a short-term solution that can lead to bigger issues down the road.
For example, if the light came on because of a faulty oxygen sensor, simply clearing the code won’t repair the sensor. The problem will persist, and the light will likely return within a few days or driving cycles. Worse, unresolved issues can reduce fuel economy, increase emissions, or even cause engine damage.
Additionally, some states require a vehicle to pass an emissions test with no active trouble codes. If the light returns during inspection, your vehicle may fail—even if it was working fine before.
So, before you reset the light, ask yourself:
– Have I identified the cause?
– Have I repaired or replaced the faulty component?
– Has the repair been tested?
Only after confirming the fix should you proceed with resetting the light.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most effective way to reset the check engine light on a 2017 Ford Escape is by using an OBD2 scanner. This tool connects to your vehicle’s diagnostic port and communicates with the onboard computer to read and clear trouble codes.
What You’ll Need
- OBD2 scanner (available at auto parts stores or online for $20–$100)
- 2017 Ford Escape with the engine off
- Access to the OBD2 port (usually under the dashboard)
Step-by-Step Instructions
Step 1: Locate the OBD2 Port
The OBD2 port in the 2017 Ford Escape is typically located under the dashboard on the driver’s side. It’s a 16-pin connector, often covered by a small flap. You may need to kneel or crouch to see it clearly.
Step 2: Plug in the Scanner
Turn the ignition to the “ON” position (but don’t start the engine). Plug the OBD2 scanner into the port. Most scanners will power on automatically.
Step 3: Read the Trouble Codes
Follow the scanner’s on-screen prompts to read the diagnostic trouble codes (DTCs). These codes will tell you what system or component is causing the check engine light to illuminate. For example:
– P0455: Large evaporative emission system leak (often a loose gas cap)
– P0133: Oxygen sensor circuit slow response
– P0300: Random/multiple cylinder misfire
Write down the codes or take a photo for reference.
Step 4: Fix the Underlying Issue
Use the trouble codes to identify and repair the problem. Common fixes include:
– Tightening or replacing the gas cap
– Replacing a faulty oxygen sensor
– Repairing vacuum leaks
– Fixing ignition coil or spark plug issues
If you’re unsure how to proceed, consult a repair manual or visit a trusted mechanic.
Step 5: Clear the Codes
Once the repair is complete, return to the scanner and select the option to “Clear Codes” or “Erase DTCs.” The scanner will send a command to the vehicle’s computer to reset the check engine light.
Step 6: Verify the Reset
Turn the ignition off, then back on. The check engine light should remain off. If it comes back on, the problem may not be fully resolved, or a new issue may have appeared.
Tips for Using an OBD2 Scanner
– Choose a scanner with live data and code definitions for better diagnostics.
– Some scanners can reset readiness monitors, which is helpful for emissions testing.
– Keep the scanner updated with the latest software for accurate readings.
Method 2: 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, clearing stored codes and turning off the light.
However, this approach has drawbacks. It resets not only the check engine light but also other systems, including:
– Radio presets
– Clock settings
– Adaptive transmission learning
– Anti-theft system (may require re-syncing)
Use this method only if you’ve confirmed the issue is fixed and you’re okay with resetting other settings.
What You’ll Need
- Wrench or socket set (usually 10mm)
- Safety gloves and glasses
- 2017 Ford Escape parked on a flat surface
Step-by-Step Instructions
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is completely off and the key is out of the ignition.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2017 Ford Escape, it’s located on the driver’s side of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery to prevent accidental contact.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer to fully discharge and reset. For a more thorough reset, wait up to 30 minutes.
Step 5: Reconnect the Battery
Reattach the negative terminal and tighten the nut securely. Make sure the connection is tight to avoid electrical issues.
Step 6: Turn On the Ignition
Turn the key to the “ON” position (do not start the engine). Wait a few seconds, then start the vehicle. The check engine light should be off.
What to Expect After Reconnecting
– The radio may ask for a security code (check your owner’s manual).
– The clock and trip odometer will reset.
– The transmission may feel slightly different as it relearns driving patterns.
– The check engine light should remain off—unless the problem persists.
Method 3: Drive Cycle Reset
Some vehicles, including the 2017 Ford Escape, can reset the check engine light automatically after completing a series of driving conditions known as a “drive cycle.” This method works only if the original issue has been fixed and the computer no longer detects a fault.
A drive cycle allows the vehicle’s onboard systems to run self-tests and confirm everything is working properly. Once all tests pass, the computer will turn off the check engine light.
Typical Drive Cycle for 2017 Ford Escape
Follow these steps to complete a drive cycle:
- Start the engine and let it idle for 2–3 minutes (cold start).
- Drive at 30–40 mph for 3–5 minutes.
- Accelerate to 55–60 mph and maintain speed for 5–10 minutes.
- Decelerate to 20 mph without braking hard.
- Repeat the cycle 2–3 times over the course of a day.
Important Notes
– The drive cycle must be completed without turning off the engine between steps.
– Avoid short trips—longer drives are more effective.
– If the light doesn’t turn off after 3–5 drive cycles, use an OBD2 scanner to check for pending codes.
Troubleshooting Common Issues
Even after resetting the check engine light, you may encounter problems. Here’s how to handle common scenarios:
The Light Comes Back On
If the check engine light returns shortly after resetting, the original issue likely wasn’t fully resolved. Use an OBD2 scanner to read the new or recurring codes. Common causes include:
– Incomplete repairs (e.g., gas cap not tightened properly)
– Intermittent sensor failures
– Wiring or electrical issues
The Light Flashes After Reset
A flashing light indicates a severe problem, such as an engine misfire. This requires immediate attention. Continuing to drive can damage the catalytic converter. Stop driving and have the vehicle towed to a repair shop.
Radio or Settings Reset After Battery Disconnect
If your radio asks for a code, check your owner’s manual or look for a card in the glove box. If you don’t have the code, contact a Ford dealer with your VIN to retrieve it.
Check Engine Light Won’t Turn Off
If the light remains on after a reset, the vehicle may have a pending code or a system that hasn’t completed its self-test. Use an OBD2 scanner to check for “pending” or “confirmed” codes. Some systems, like evaporative emissions, require specific conditions to test.
When to See a Mechanic
While many check engine light issues can be resolved at home, some problems require professional help. Visit a mechanic if:
– The light is flashing
