Before resetting the light, it’s important to understand what it means. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, and other critical systems.
When a problem is detected, the system stores a trouble code and triggers the light. These codes range from minor issues like a loose gas cap to serious problems like a failing catalytic converter.
Common causes in the 2013 Chevy Equinox include:
- Loose or damaged gas cap
- Faulty oxygen (O2) sensor
- Mass airflow (MAF) sensor issues
- Spark plug or ignition coil problems
- Evaporative emissions system leaks
- Catalytic converter inefficiency
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage. So, always diagnose the issue before resetting.
Step 1: Diagnose the Problem
You can’t fix what you don’t understand. The first step in resetting the check engine light is identifying the cause.
Use an OBD2 Scanner
The most accurate way to diagnose the issue is with an OBD2 scanner. These devices plug into your vehicle’s diagnostic port and read the trouble codes stored in the computer.
Here’s how to use one:
- Locate the OBD2 port. In the 2013 Chevy Equinox, it’s usually under the dashboard, near the driver’s side knee panel. It’s a 16-pin connector, often black or gray.
- Turn off the engine and insert the scanner.
- Turn the ignition to the “ON” position (but don’t start the engine).
- Follow the scanner’s instructions to read the codes. Most scanners display the code (like P0420) and a brief description.
Once you have the code, look it up online or in the scanner’s manual. For example, P0420 often indicates a catalytic converter problem, while P0455 suggests an evaporative emissions leak.
Check the Gas Cap
Before investing in a scanner, try this simple fix:
- Turn off the engine and remove the gas cap.
- Inspect it for cracks, wear, or a damaged seal.
- Reinstall it firmly until you hear it click 3–5 times.
- Drive the vehicle for a few days. If the light was due to a loose cap, it may turn off on its own.
This is one of the most common causes of the check engine light in the Equinox and costs nothing to fix.
Step 2: Fix the Underlying Issue
Resetting the light without fixing the problem is like turning off a smoke alarm while the house is on fire. The light will likely return.
Common Repairs for the 2013 Equinox
Depending on the code, here are some typical fixes:
- Replace the gas cap: If it’s damaged, buy a new OEM or high-quality aftermarket cap.
- Clean or replace the MAF sensor: Use MAF cleaner spray to remove dirt and debris.
- Replace spark plugs or ignition coils: Worn plugs can cause misfires. Use the correct type for your engine (4-cylinder or V6).
- Repair EVAP system leaks: This may involve replacing hoses or the purge valve.
- Replace oxygen sensors: Located in the exhaust system, these wear out over time.
If you’re not comfortable doing these repairs, take your vehicle to a trusted mechanic. Some issues, like catalytic converter failure, require professional diagnosis and replacement.
Step 3: Reset the Check Engine Light
Once the issue is fixed, it’s time to reset the light. There are several methods, each with pros and cons.
Method 1: Use an OBD2 Scanner (Recommended)
This is the most reliable and safest way to reset the check engine light.
Steps:
- Ensure the engine is off and the OBD2 scanner is connected.
- Turn the ignition to the “ON” position.
- Navigate the scanner menu to “Clear Codes” or “Erase DTCs.”
- Confirm the action. The scanner will send a command to the vehicle’s computer to clear the stored codes.
- Turn off the ignition and disconnect the scanner.
- Start the engine. The check engine light should be off.
Tip: Some scanners also allow you to view live data and monitor system readiness. This helps confirm the repair was successful.
Method 2: Drive Cycle Reset
After repairs, your vehicle may reset the light automatically through a “drive cycle.” This is a series of driving conditions that allow the onboard computer to test various systems.
For the 2013 Chevy Equinox, a typical drive cycle includes:
- Cold start: Let the engine sit for at least 8 hours.
- Idle for 2–3 minutes.
- Drive at 30–40 mph for 5 minutes with steady throttle.
- Accelerate to 55–60 mph and cruise for 10 minutes.
- Decelerate without braking (coast) for 3–5 minutes.
- Repeat the cycle 2–3 times over several days.
Note: Not all systems will reset automatically. Some require specific conditions, like highway driving or cold weather. Check your owner’s manual for details.
Method 3: Disconnect the Battery
This method forces the vehicle’s computer to reset by cutting power. However, it’s not always effective and has downsides.
Steps:
- Turn off the engine and remove the key.
- Open the hood and locate the battery.
- Use a wrench to loosen the negative (black) terminal clamp.
- Remove the negative cable and wait 15–30 minutes. This allows the computer’s memory to drain.
- Reconnect the cable and tighten it securely.
- Start the engine. The check engine light may be off.
Warning: Disconnecting the battery can reset other systems, including:
- Radio presets
- Power window settings
- Climate control memory
- Anti-theft system (may require reactivation)
Also, some vehicles require a “relearn” procedure for the throttle body or idle speed. This may need a scan tool or dealer visit.
Method 4: Use the Gas Pedal Trick (Not Recommended)
Some older vehicles allow you to reset the computer by pressing the gas pedal in a specific sequence. However, this method does not work on the 2013 Chevy Equinox and can damage the throttle system.
Avoid this trick. It’s outdated and ineffective for modern OBD2 systems.
Troubleshooting: What If the Light Comes Back?
If the check engine light returns after resetting, the problem wasn’t fully resolved. Here’s what to do:
Recheck the Trouble Codes
Use your OBD2 scanner to read the new or recurring codes. Compare them to the original ones. If they’re the same, the repair may have been incomplete.
Inspect Related Components
For example, if the code is P0171 (system too lean), check:
- Vacuum leaks in hoses or intake manifold
- Dirty fuel injectors
- Faulty fuel pressure regulator
- Clogged air filter
Even small leaks can trigger the light.
Check for Pending Codes
Some scanners show “pending” codes—issues that haven’t yet triggered the light. These can give you early warning of developing problems.
Visit a Mechanic
If you’ve tried everything and the light keeps coming back, it’s time for professional help. A certified technician can perform advanced diagnostics, such as:
- Smoke testing for EVAP leaks
- Compression testing
- Fuel pressure testing
- Oscilloscope analysis of sensors
They may also check for technical service bulletins (TSBs) related to your Equinox model.
Preventing Future Check Engine Lights
An ounce of prevention is worth a pound of cure. Here’s how to keep your 2013 Chevy Equinox running smoothly:
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
