Before jumping into reset methods, it’s crucial to understand what the check engine light actually means. In your 2016 Nissan Versa, this light—also known as the Malfunction Indicator Lamp (MIL)—is controlled by the vehicle’s onboard diagnostic system (OBD2). When the system detects a problem that could affect emissions or engine performance, it triggers the light and stores a diagnostic trouble code (DTC).
These codes range from minor issues like a loose gas cap (P0457) to more serious problems like a faulty oxygen sensor (P0135) or catalytic converter failure (P0420). Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time.
The key takeaway? The check engine light is a warning, not a decoration. Resetting it without addressing the root cause is only a temporary fix. Always diagnose the issue first.
Step 1: Diagnose the Problem
The first and most important step in resetting the check engine light is figuring out why it came on in the first place. You can’t fix what you don’t understand.
Use an OBD2 Scanner
The best way to diagnose the issue is by using an OBD2 scanner. These devices plug into your car’s OBD2 port—usually located under the dashboard, near the steering column—and read the stored trouble codes.
Here’s how to do it:
- Turn off the ignition and locate the OBD2 port. In the 2016 Nissan Versa, it’s typically found under the dashboard on the driver’s side, just above the pedals.
- Plug in your OBD2 scanner. Make sure it’s compatible with your vehicle (most modern scanners work with all OBD2-equipped cars made after 1996).
- Turn the ignition to the “ON” position (but don’t start the engine). The scanner should power up and communicate with the car’s computer.
- Follow the scanner’s instructions to retrieve the trouble codes. Most scanners will display codes like “P0420” or “P0171.”
- Write down the codes and use the scanner’s built-in database or an online resource to interpret them. For example, P0420 usually indicates a catalytic converter efficiency problem.
If you don’t own a scanner, many auto parts stores (like AutoZone, O’Reilly, or Advance Auto Parts) offer free code reading services. Just drive in, and a technician will plug in a scanner for you.
Check Common Causes
While waiting to get a code read, you can check a few common culprits:
- Gas cap: A loose, damaged, or missing gas cap is one of the most frequent causes of the check engine light. Tighten it securely or replace it if cracked.
- Spark plugs and wires: Worn spark plugs can cause misfires, triggering codes like P0300 (random misfire). Inspect them for wear or carbon buildup.
- Air filter: A clogged air filter can restrict airflow and affect engine performance. Check and replace if dirty.
- Mass airflow (MAF) sensor: A dirty or faulty MAF sensor can cause poor fuel economy and performance issues. Clean it with MAF sensor cleaner if accessible.
Once you’ve identified the problem, you can move on to fixing it—and then resetting the light.
Step 2: Fix the Underlying Issue
Resetting the check engine light won’t do any good if the problem still exists. The light will simply come back on once the car’s computer detects the same issue again.
Common Repairs for the 2016 Nissan Versa
Here are some typical fixes based on common trouble codes:
- P0457 (Evaporative Emission Control System Leak): Replace or tighten the gas cap. If that doesn’t work, inspect the EVAP system for leaks.
- P0171 (System Too Lean): Check for vacuum leaks, clean the MAF sensor, or replace the air filter.
- P0300-P0304 (Misfire Detected): Replace spark plugs, ignition coils, or fuel injectors as needed.
- P0420 (Catalyst System Efficiency Below Threshold): This often requires replacing the catalytic converter, but first rule out oxygen sensor issues.
- P0135 (O2 Sensor Heater Circuit Malfunction): Replace the upstream oxygen sensor.
Always use quality replacement parts. Cheap or counterfeit components may fail quickly and trigger the light again.
When to See a Mechanic
If you’re unsure about the diagnosis or don’t have the tools to fix the issue, it’s best to consult a certified mechanic. They have advanced diagnostic equipment and experience with Nissan vehicles. Paying for a professional repair now can save you money and headaches down the road.
Step 3: Reset the Check Engine Light
Once the problem is fixed, it’s time to reset the check engine light. There are several methods, each with pros and cons.
Method 1: Use an OBD2 Scanner (Recommended)
This is the safest and most effective way to reset the light.
- Ensure the repair has been completed and the ignition is off.
- Plug the OBD2 scanner into the OBD2 port.
- Turn the ignition to the “ON” position.
- Navigate the scanner menu to find the “Clear Codes” or “Reset” option.
- Confirm the reset. The scanner will send a command to the car’s computer to erase the stored trouble codes.
- Turn off the ignition and unplug the scanner.
- Start the engine. The check engine light should be off.
Tip: Some scanners also allow you to view live data and confirm that sensors are working properly after the repair.
Method 2: Complete a Driving Cycle
If you don’t have a scanner, the car’s computer may reset the light automatically after you complete a specific driving pattern, known as a “driving cycle.” This allows the onboard diagnostics to recheck systems and confirm the issue is resolved.
Here’s a typical driving cycle for the 2016 Nissan Versa:
- Start the engine and let it idle for 2–3 minutes to reach operating temperature.
- Drive at a steady speed of 30–40 mph for about 5 minutes.
- Accelerate to 55–60 mph and maintain that speed for 5–10 minutes.
- Decelerate slowly without braking hard.
- Repeat the cycle 2–3 times over the course of a few days.
After completing the driving cycle, the computer may clear the codes and turn off the check engine light—especially if the issue was minor, like a loose gas cap.
Note: This method isn’t guaranteed. If the problem persists, the light will return.
Method 3: Disconnect the Battery (Last Resort)
Disconnecting the car battery can reset the computer and clear the check engine light. However, this method has downsides and should only be used if other options aren’t available.
- Turn off the ignition and remove the key.
- Open the hood and locate the battery.
- Use a wrench to loosen the negative (-) terminal clamp.
- Remove the negative cable and wait at least 15 minutes. This allows the car’s computer to fully reset.
- Reconnect the negative cable and tighten the clamp.
- Start the engine. The check engine light should be off.
Warning: Disconnecting the battery will also reset:
- Radio presets and clock
- Trip computer data
- Learned engine parameters (may cause rough idle initially)
- Anti-theft system (may require re-syncing)
Additionally, if the underlying issue isn’t fixed, the light will return once the computer re-detects the problem.
Step 4: Monitor the Vehicle
After resetting the light, it’s essential to monitor your car for the next few days.
Drive Normally
Take your Versa on regular drives—city, highway, and idle time. This gives the computer a chance to run all its diagnostic tests.
Watch for the Light
If the check engine light comes back on, the problem wasn’t fully resolved. Recheck the trouble codes and consider a more thorough inspection.
Check for Performance Issues
Pay attention to:
- Rough idling
