Why Is the Check Engine Light On?
Before you reset the light, it’s important 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 Silverado’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, fuel efficiency, and other critical systems.
When something goes wrong, the computer stores a trouble code and turns on the light. Common causes include:
- A loose or faulty gas cap
- Failing oxygen (O2) sensor
- Dirty or failing mass airflow (MAF) sensor
- Catalytic converter issues
- Spark plug or ignition coil problems
- Exhaust gas recirculation (EGR) valve malfunction
Ignoring the light can lead to reduced fuel economy, poor performance, or even engine damage. That’s why it’s essential to diagnose the issue before resetting the light.
How to Diagnose the Problem
You can’t reset the light effectively if the underlying problem still exists. Here’s how to find out what’s wrong:
Step 1: Use an OBD2 Scanner

The easiest way to read trouble codes is with an OBD2 scanner. These devices plug into the diagnostic port under your dashboard (usually near the steering column) and display the code(s) causing the light.
Most auto parts stores (like AutoZone or O’Reilly) offer free code reading. Just drive in, and they’ll hook up a scanner for you. They’ll tell you the code—like P0420 (catalytic converter efficiency below threshold)—and give you a basic explanation.
Step 2: Research the Code
Once you have the code, look it up online or in your owner’s manual. Websites like OBD-Codes.com provide detailed explanations and possible fixes.
For example, code P0442 might mean a small EVAP leak—often caused by a loose gas cap. Tightening or replacing the cap could solve the problem.
Step 3: Fix the Issue
After identifying the problem, repair or replace the faulty part. This might be as simple as tightening the gas cap or as involved as replacing an oxygen sensor.
Only after the repair is complete should you reset the check engine light.
Method 1: Reset Using an OBD2 Scanner (Recommended)
Using an OBD2 scanner is the most accurate and reliable way to reset the check engine light on your 2016 Chevy Silverado. It ensures the code is cleared properly and gives you full control over the process.
What You’ll Need
- OBD2 scanner (Bluetooth or wired)
- Your 2016 Chevy Silverado
- Ignition key
Step-by-Step Instructions
Step 1: Locate the OBD2 Port
The OBD2 port in your 2016 Silverado is usually under the dashboard, near the driver’s side knee area. It’s a 16-pin connector, often black or gray. You might need to crouch down to see it clearly.
Step 2: Plug in the Scanner
Turn off the engine, then plug the OBD2 scanner into the port. Make sure it’s fully seated.
Step 3: Turn the Ignition to “On”
Turn the key to the “ON” position (but don’t start the engine). This powers up the vehicle’s computer and allows the scanner to communicate with it.
Step 4: Power On the Scanner
Turn on the scanner. Most models will automatically detect your vehicle and display a menu.
Step 5: Read the Codes
Select “Read Codes” or a similar option. The scanner will display any stored trouble codes. Write them down or take a photo for reference.
Step 6: Clear the Codes
Once you’ve confirmed the issue is fixed, select “Clear Codes” or “Erase DTCs.” The scanner will send a command to the vehicle’s computer to reset the check engine light.
Step 7: Turn Off the Ignition
After clearing the codes, turn the ignition off and unplug the scanner.
Step 8: Start the Engine
Start your Silverado. The check engine light should be off. If it comes back on, the problem may not be fully resolved.
Tips for Success
- Use a scanner with live data if possible—it lets you monitor sensor readings in real time.
- If you don’t own a scanner, borrow one from a friend or use a free service at an auto parts store.
- Some scanners require you to clear codes before reading them—check your model’s instructions.
Method 2: Disconnect the Battery (Manual Reset)
If you don’t have an OBD2 scanner, you can try resetting 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.
What You’ll Need
- Wrench or socket set (usually 10mm)
- Safety gloves and glasses
- Your 2016 Chevy Silverado
Step-by-Step Instructions
Step 1: Turn Off the Engine and Remove the Key
Make sure the truck is off and the key is out of the ignition.
Step 2: Locate the Battery
Open the hood and find the battery. In most 2016 Silverados, it’s on the driver’s side.
Step 3: Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery cable. Carefully remove the cable and tuck it away from the battery terminal so it doesn’t accidentally reconnect.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This gives the vehicle’s computer time to fully reset. Some recommend up to 30 minutes for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely.
Step 6: Start the Engine
Turn the key and start your Silverado. The check engine light should be off.
Important Notes
- This method may also reset other systems, like the radio presets, clock, and adaptive transmission settings. You may need to reprogram these.
- If the underlying issue isn’t fixed, the light will likely come back on after a few drive cycles.
- Avoid disconnecting the positive terminal unless necessary—it’s riskier and can cause sparks.
Method 3: Drive Cycle Reset (Natural Clearing)
Sometimes, the check engine light will turn off on its own after the problem is fixed and the vehicle completes a “drive cycle.” A drive cycle is a series of driving conditions that allow the onboard computer to test all emissions and engine systems.
What Is a Drive Cycle?
A drive cycle includes:
- Cold start (engine off for at least 8 hours)
- Idle for 2–3 minutes
- Drive at varying speeds (city and highway)
- Accelerate and decelerate smoothly
- Let the engine reach normal operating temperature
Typical Drive Cycle for 2016 Silverado
Here’s a common drive cycle pattern:
Step 1: Cold Start
Start the engine after it’s been off overnight. Let it idle for 2 minutes.
Step 2: Drive at 30–40 mph
Drive for 5 minutes at a steady speed.
Step 3: Accelerate to 55 mph
Gradually increase speed to 55 mph and maintain for 3–5 minutes.
Step 4: Decelerate and Stop
Slow down and come to a complete stop. Repeat this process 2–3 times.
Step 5: Highway Driving
If possible, drive on the highway at 60–65 mph for 10 minutes.
After completing the drive cycle, park the truck and turn it off. The next time you start it, the check engine light may be off—if the issue was minor and fully resolved.
Limitations
- This method only works if the problem is truly fixed.
- It can take several days of driving to complete all monitor tests.
- Some codes (like catalytic converter issues) require multiple drive cycles.
Method 4: Gas Pedal Trick (Not Recommended)
Some online sources suggest a “gas pedal trick” to reset the check engine light: press the accelerator three times quickly, then turn the key. However, this method is not reliable for the 2016 Chevy Silverado and may not work at all.
The OBD2 system in modern vehicles like the Silverado doesn’t respond to pedal inputs for resetting codes. This trick may have worked on older cars, but it’s outdated and ineffective here.
Stick to the OBD2 scanner or battery disconnect methods for best results.
Troubleshooting: Why Won’t the Light Turn Off?
If you’ve tried resetting the light and it keeps coming back, there’s likely an unresolved issue. Here’s how to troubleshoot:
1. The Problem Isn’t Fixed
Even if you replaced a part, it might not be installed correctly or could be defective. Double-check your repair.
2. Intermittent Fault
Some issues (like a loose wire or failing sensor) only occur under certain conditions. The light may turn off temporarily but return later.
3. Multiple Codes
Your scanner might show more than one code. Fix them in order—some codes can trigger others.
4. Software Glitch
Rarely, the vehicle’s computer may have a software issue. A dealership can perform a reflash or update.
5. Aftermarket Parts
Non-OEM parts (like cheap oxygen sensors) may not communicate properly with the computer, causing the light to stay on.
Preventing Future Check Engine Lights
The best way to avoid resetting the light is to prevent it from coming on in the first place. Here are some tips:
- Use quality fuel: Stick to Top Tier gasoline to reduce carbon buildup.
- Replace the air filter regularly: A dirty filter reduces airflow and triggers MAF sensor codes.
- Tighten the gas cap after filling up: A loose cap is one of the most common causes.
- Follow the maintenance schedule: Change oil, spark plugs, and fluids as recommended.
- Listen for unusual sounds: Knocking, pinging, or rough idling can signal engine problems.
When to See a Mechanic
While many check engine light issues are minor, some require professional help. See a mechanic if:
- The light is flashing (indicates a severe problem like engine misfire)
- You notice poor performance, stalling, or overheating
- The light keeps coming back after multiple resets
- You’re unsure how to fix the issue
A certified technician can perform advanced diagnostics and ensure your Silverado runs safely.
Conclusion
Resetting the check engine light on your 2016 Chevy Silverado is straightforward once you understand the process. The best method is using an OBD2 scanner—it’s accurate, safe, and gives you full control. If you don’t have a scanner, disconnecting the battery can work, but it’s less reliable and may reset other systems.
Always diagnose the problem before resetting the light. A reset won’t fix a faulty oxygen sensor or clogged catalytic converter. And remember: if the light comes back, the issue isn’t solved.
By following this guide, you’ll keep your Silverado running smoothly and avoid unnecessary trips to the shop. Stay proactive with maintenance, and that check engine light will stay off for good.
Drive safe!
