In the 2010 Nissan Murano, common causes include:
- A loose, damaged, or missing gas cap
- Faulty oxygen (O2) sensor
- Mass airflow (MAF) sensor issues
- Catalytic converter problems
- Spark plug or ignition coil failure
- Evaporative emissions (EVAP) system leaks
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. That’s why it’s essential to address the root cause before resetting the light.
Can You Just Reset the Light Without Fixing the Problem?
Technically, yes—you can reset the check engine light without fixing the issue. But this is strongly discouraged. Resetting the light without resolving the underlying problem is like turning off a smoke alarm while your kitchen is on fire. The issue remains, and the light will likely come back on after a few drive cycles.
Moreover, if the problem affects emissions or engine performance, your Murano may fail an emissions test or experience drivability issues like rough idling, hesitation, or poor fuel economy. Always diagnose and repair the issue first.
Method 1: Use an OBD2 Scanner (Recommended)
The safest and most accurate way to reset the check engine light on your 2010 Nissan Murano is by using an OBD2 scanner. This handheld device plugs into your vehicle’s diagnostic port and reads the trouble codes stored in the engine control unit (ECU). Once you’ve fixed the problem, the scanner can clear the codes and turn off the light.
Step 1: Locate the OBD2 Port
In the 2010 Murano, the OBD2 port is usually located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector, often covered by a small plastic panel. You may need to kneel or crouch to see it clearly.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s securely connected. Some scanners require you to turn the ignition to the “ON” position (without starting the engine) to power up.
Step 3: Read the Trouble Codes
Follow the scanner’s instructions to read the diagnostic trouble codes (DTCs). These codes—like P0420 (catalytic converter efficiency) or P0455 (large EVAP leak)—tell you exactly what’s wrong. Write them down or take a photo for reference.
Step 4: Fix the Underlying Issue
Use the codes to guide your repair. For example:
- If the code is P0457 (loose gas cap), tighten or replace the cap.
- If it’s P0135 (O2 sensor heater circuit), you may need to replace the sensor.
- If it’s P0300 (random misfire), check spark plugs, coils, or fuel injectors.
After making the repair, double-check all connections and ensure everything is properly installed.
Step 5: Clear the Codes
With the ignition on and the engine off, use the scanner’s “Clear Codes” or “Erase DTCs” function. The scanner will send a signal to the ECU to reset the check engine light. You should see a confirmation message on the screen.
Step 6: Verify the Reset
Turn off the ignition, wait 10–15 seconds, then restart the engine. If the repair was successful, the check engine light should remain off. If it comes back on, the problem may not be fully resolved—or a new issue has appeared.
Tip: Invest in a basic OBD2 scanner (around $20–$50) for home use. Popular brands include BlueDriver, Autel, and Innova. Some even connect to your smartphone via Bluetooth for real-time monitoring.
Method 2: Drive Cycle Reset (Automatic Clear)
In some cases, the check engine light will turn off on its own after the problem is fixed and the vehicle completes a specific driving pattern called a “drive cycle.” This method works best for minor issues like a loose gas cap or temporary sensor glitch.
What Is a Drive Cycle?
A drive cycle is a series of driving conditions that allow the vehicle’s onboard computer to retest emissions systems and confirm that repairs were successful. Once all monitors pass, the ECU may automatically clear the trouble codes and turn off the check engine light.
Recommended Drive Cycle for 2010 Nissan Murano
Follow these steps to complete a typical drive cycle:
- Start the engine and let it idle for 2–3 minutes (cold start).
- Drive at a steady speed of 30–40 mph for 3–5 minutes.
- Accelerate to 55–60 mph and maintain that speed for 5–10 minutes.
- Decelerate slowly (without braking hard) and come to a stop.
- Repeat the cycle 2–3 times over the course of a day.
After completing the drive cycle, check if the light is off. This process can take anywhere from one day to a week, depending on driving habits and the severity of the issue.
Note: Not all problems will clear automatically. If the light remains on after several drive cycles, use an OBD2 scanner to check for pending or stored codes.
Method 3: Disconnect the Battery (Last Resort)
Disconnecting the battery can reset the check engine light by cutting power to the ECU and clearing its memory. However, this method should only be used as a last resort because it can also erase important data like radio presets, adaptive transmission settings, and learned engine parameters.
Step 1: Turn Off the Engine and Remove Keys
Make sure the vehicle is off and the keys are out of the ignition. For safety, wear gloves and eye protection.
Step 2: Locate the Battery
In the 2010 Murano, the battery is under the hood on the driver’s side. It’s housed in a black plastic case with positive (+) and negative (-) terminals.
Step 3: Disconnect the Negative Terminal
Use a wrench (usually 10mm) to loosen the nut on the negative (black) cable. Carefully remove the cable from the terminal and tuck it away so it doesn’t touch metal.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the ECU to fully discharge and reset. For a more thorough reset, wait up to 30 minutes.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is tight to avoid electrical issues.
Step 6: Start the Engine
Turn the ignition to “ON” and wait for the dashboard lights to illuminate. Then start the engine. The check engine light may flash briefly but should turn off after a few seconds.
Warning: After reconnecting the battery, you may need to reset the radio, clock, and power windows. The transmission may also feel less responsive for a few drives as the ECU relearns driving patterns.
Method 4: Replace the Gas Cap (Common Fix)
One of the most common reasons the check engine light comes on in the 2010 Murano is a loose, damaged, or missing gas cap. The EVAP system monitors fuel vapor leaks, and a faulty cap can trigger codes like P0455 or P0457.
Step 1: Check the Gas Cap
After refueling, make sure the gas cap is tightened until you hear 3–4 clicks. If it’s cracked, warped, or the seal is worn, replace it.
Step 2: Use OEM or High-Quality Replacement
Buy a genuine Nissan gas cap or a high-quality aftermarket one that meets OEM specifications. Cheap caps may not seal properly and can cause the light to return.
Step 3: Drive and Monitor
After replacing the cap, drive normally for a few days. The light may turn off automatically after a drive cycle. If not, use an OBD2 scanner to clear the code.
Pro Tip: Always tighten the gas cap after every fill-up. It’s a simple habit that can prevent unnecessary check engine light alerts.
Troubleshooting: What If the Light Comes Back On?
If the check engine light returns after resetting it, the problem wasn’t fully resolved. Here’s what to do:
Recheck the Repair
Go back to the original issue. Did you replace the correct part? Was it installed properly? For example, if you replaced an O2 sensor, ensure it’s the right one (upstream vs. downstream) and wired correctly.
Scan for New Codes
Use an OBD2 scanner to read the new or pending codes. Sometimes, fixing one issue reveals another. For instance, a misfire might have damaged the catalytic converter.
Inspect Related Systems
Some problems are interconnected. A faulty MAF sensor can cause misfires, which in turn damage the catalytic converter. Check all related components.
Visit a Mechanic
If you’re unable to diagnose or fix the issue, take your Murano to a trusted mechanic or Nissan dealership. They have advanced diagnostic tools and can perform a thorough inspection.
When to Seek Professional Help
While many check engine light issues can be handled at home, some require professional expertise. Seek help if:
- The light is flashing (indicates a severe misfire that can damage the catalytic converter)
- You smell fuel, hear unusual noises, or notice performance issues
- The problem involves the transmission, ABS, or airbags
- You’ve tried multiple fixes and the light keeps returning
- You’re unsure about the diagnosis or repair process
Ignoring a flashing check engine light can lead to expensive repairs. It’s better to be safe than sorry.
