• Insulated Gloves (optional): If you’re working near the battery.
• Pen and Paper (or phone notes): To write down trouble codes before clearing them.

You don’t need a mechanic’s license or a $500 tool. But you do need to be patient and careful. The goal isn’t just to turn the light off—it’s to understand why it came on in the first place.

Tip: Avoid cheap $10 OBD2 scanners from gas stations. They often can’t read or clear Nissan-specific codes. Invest in a reliable model—it’ll pay off in the long run.

Step-by-Step Guide to 2026 Guide How to Reset Check Engine Light on 2016 Nissan Murano

This guide is designed for the average driver. No special skills needed. Just follow these steps carefully, and you’ll safely reset the check engine light on your 2016 Murano.

Step 1: Understand the Light – Don’t Reset Blindly

The first rule of resetting the check engine light: don’t reset it without knowing why it’s on. The 2026 Guide How to Reset Check Engine Light on 2016 Nissan Murano starts with diagnosis, not deletion.

Ask yourself: Is the light steady or flashing? A steady light means a minor issue (like a loose gas cap). A flashing light means a severe problem (like misfiring cylinders). If it’s flashing, do not drive—pull over and get it towed to a shop.

For a steady light, proceed. But remember: resetting without fixing the root cause is like putting a band-aid on a broken leg.

Step 2: Read the Trouble Codes with an OBD2 Scanner

Your Murano stores diagnostic trouble codes (DTCs) when the check engine light comes on. These codes tell you exactly what’s wrong.

1. Locate the OBD2 port under the dashboard, just left of the steering wheel. It’s a 16-pin connector—usually black or gray.
2. Plug in your OBD2 scanner. Make sure the car is off (ignition in “OFF” position).
3. Turn the ignition to “ON” (don’t start the engine). The scanner should power up.
4. Press the “Read Codes” button. Wait 10–30 seconds. The scanner will display one or more codes (e.g., P0455, P0171, P0300).

Write down each code. Use your phone or a notepad. You’ll need this info to research the issue or discuss it with a mechanic.

Warning: If your scanner says “No Communication” or “Link Failure,” try wiggling the connector, checking fuses, or restarting the scanner. A loose connection is the #1 cause.

Step 3: Research the Codes (Free & Easy)

Now, decode what those numbers mean. You don’t need to memorize them—just Google them.

Example: A code like P0420 means “Catalyst System Efficiency Below Threshold (Bank 1)”—often related to a failing catalytic converter or oxygen sensor. P0455 means “Evaporative Emission System Leak Detected (Large Leak)”—usually a loose or cracked gas cap, hose, or purge valve.

Use free resources:

• OBD-Codes.com – Clear explanations and fix suggestions
• Nissan Forums – Real Murano owners sharing fixes
• YouTube – Search “2016 Murano P0455 fix” for video guides

Once you know the issue, decide: Can you fix it yourself? Or should you take it to a shop?

Step 4: Fix the Problem (If Possible)

Here are the most common 2016 Murano check engine light causes—and how to fix them:

Loose Gas Cap (P0455, P0457)

• Remove the gas cap and inspect the rubber seal. Look for cracks, warping, or debris.
• Tighten the cap until it clicks 2–3 times.
• Drive for 20–30 miles. The light may turn off automatically.

Faulty Oxygen Sensor (P0130–P0167)

• These sensors monitor exhaust gases. A bad one hurts fuel economy and emissions.
• Replacing it requires tools (wrench, socket set). Cost: $150–$300 at a shop.
• DIY? Only if you’re comfortable under the car. The front sensor is near the catalytic converter.

EVAP System Leak (P0455, P0442)

• Check all EVAP hoses (plastic tubes near the fuel tank). Look for cracks, splits, or disconnections.
• Inspect the charcoal canister and purge valve. These are under the car—use a flashlight.
• If a hose is damaged, replace it with OEM or high-quality aftermarket parts.

Misfire (P0300–P0306)

• Caused by bad spark plugs, ignition coils, or fuel injectors.
• Listen for rough idle, hesitation, or loss of power.
• Spark plugs should be replaced every 60,000 miles. Use NGK or Denso OEM-grade plugs.

Only after fixing the issue should you reset the light. Otherwise, it’ll come back—sometimes within minutes.

Pro Tip: For minor issues like a loose cap, drive 50–100 miles after tightening. The car’s computer needs time to “relearn” and confirm the problem is gone. The light may turn off on its own.

Step 5: Clear the Codes Using Your OBD2 Scanner

Now it’s time to reset. This is the core of the 2026 Guide How to Reset Check Engine Light on 2016 Nissan Murano.

1. With the ignition in “ON” (engine off), plug in the OBD2 scanner.
2. Press “Clear Codes” or “Erase Codes.”
3. Confirm the action. The scanner will say “Codes Cleared” or “DTCs Erased.”
4. Unplug the scanner.
5. Turn the ignition to “OFF,” then back to “ON.”

The check engine light should be gone. If it’s still on, the problem wasn’t fixed—or a new issue exists.

Warning: Never clear codes without fixing the root cause. Some states (like California) require smog tests with no stored codes. A cleared code list doesn’t mean the car is clean—it just hides the evidence.

Step 6: Drive the Car to Reset Monitors (Optional but Smart)

Even after clearing codes, your Murano’s computer has “readiness monitors” that track emissions systems. These take time to complete a full test cycle.

To speed this up, do a “drive cycle”:

• Drive 5–10 minutes at 30–40 mph (city roads)
• Accelerate to 55–60 mph and cruise for 10–15 minutes (highway)
• Decelerate to 30 mph (no braking)
• Stop and idle for 30 seconds
• Repeat 2–3 times

After this, use your OBD2 scanner to check “Readiness Monitors.” All should show “Complete” or “Ready.” This is crucial for smog tests or selling the car.

Step 7: Verify the Light Stays Off

Drive for 3–5 days (100–200 miles). If the light returns, the problem wasn’t fully fixed.

Use your scanner again to read the new code. Compare it to the old one. Same code? The repair failed. Different code? A new issue has emerged.

At this point, consider:

• Re-checking your repair (e.g., was the gas cap really tight?)
• Getting a professional diagnostic (many shops do it for free)
• Using a more advanced scanner (like a BlueDriver or Foxwell) for live data

Pro Tips & Common Mistakes to Avoid

Pro Tip 1: Always read codes before clearing them. You’ll save time and avoid repeating the same mistake. Think of it like taking a photo before erasing the whiteboard.

Pro Tip 2: Use a scanner with live data. Models like BlueDriver show real-time sensor readings (O2 voltage, fuel trims, etc.). This helps confirm a repair worked.

Pro Tip 3: Keep a log of codes and fixes. Use a notebook or app. It helps track recurring issues and impresses buyers if you sell the car.

Pro Tip 4: For persistent lights, check the battery voltage. A weak battery can trigger false codes. Use a multimeter—12.6V when off, 13.7–14.7V when running.

Common Mistake #1: Disconnecting the Battery to Reset the Light
Many people think pulling the negative battery cable will clear the light. It can, but it’s a bad idea. You’ll:

• Lose radio presets, clock, and navigation settings
• Reset the ECU, which can cause rough idle or poor performance
• Not clear stored freeze frame data (useful for mechanics)

Use an OBD2 scanner instead. It’s cleaner, safer, and more precise.

Common Mistake #2: Resetting Before a Smog Test
Some drivers clear codes right before a smog test to hide issues. But smog stations check readiness monitors. If they’re incomplete, the car fails. Worse, they may flag you for tampering.

Solution: Fix the problem, clear codes, then complete a full drive cycle. Wait 3–5 days before testing.

Common Mistake #3: Ignoring the Flashing Light
A flashing check engine light means stop driving. It usually indicates a misfire that can damage the catalytic converter. Driving with a flashing light can turn a $200 repair into a $1,500 one.

Common Mistake #4: Buying a $10 OBD2 Scanner
Cheap scanners can’t read all Nissan-specific codes (like P1421, P1706). They also lack freeze frame data and readiness monitor checks. Invest in a mid-range model—it’s worth it.

Common Mistake #5: Forgetting to Tighten the Gas Cap
The gas cap is the #1 cause of check engine lights in the 2016 Murano. Always check it first. A $15 cap can save you $100+ in diagnostics.

FAQs About 2026 Guide How to Reset Check Engine Light on 2016 Nissan Murano

Q1: Can I reset the check engine light without a scanner?
Technically, yes—by disconnecting the battery for 15–30 minutes. But this method is outdated and risky. You’ll lose settings and may not fully reset the system.
