Key Takeaways

• Diagnose the issue first: Use an OBD2 scanner to read error codes before resetting the light.

Why This Matters / Understanding the Problem

You’re driving along, enjoying your Infiniti G35’s smooth ride, when suddenly—bam—the check engine light pops on. Your heart skips a beat. Is it serious? Will it cost a fortune? Or is it just a minor hiccup?

Here’s the truth: that little orange light doesn’t always mean disaster. Sometimes, it’s triggered by something as simple as a loose gas cap. But ignoring it? That’s how small issues turn into expensive repairs.

That’s where this how to reset check engine light Infiniti G35 2026 guide comes in. Whether you’ve just fixed the issue or want to clear the code after a repair, resetting the light properly ensures your car’s computer knows everything’s back to normal. And yes—you can do it yourself without a trip to the dealership.

What You Need

Before we dive in, let’s make sure you’re set up for success. You don’t need fancy tools or a mechanic’s certification—just a few basics:

• OBD2 scanner (also called an OBD-II code reader) – This is the most reliable way to reset the light. You can get a basic one for under $20 online or at auto parts stores.
• Your car keys – You’ll need them to turn the ignition on and off.
• A few minutes of quiet time – No rush, no distractions.

Note: Some older methods (like disconnecting the battery) might work temporarily, but they can also reset your radio presets, clock, and even adaptive transmission settings. We’ll stick with the smarter, safer approach using an OBD2 scanner—the same tool mechanics use.

Step-by-Step Guide to How to Reset Check Engine Light Infiniti G35 2026 Guide

Step 1: Locate the OBD2 Port

First things first—find your car’s OBD2 port. In the Infiniti G35 (including the 2026 model), it’s usually tucked under the dashboard on the driver’s side, near the steering column.

It looks like a rectangular socket with 16 pins inside. If you’re having trouble spotting it, crouch down and look up—you’ll see it right below the knee panel. No need to remove anything; it should be easily accessible.

Step 2: Plug in Your OBD2 Scanner

Turn off the engine completely—key out of the ignition. Then, plug your OBD2 scanner into the port. Make sure it clicks in securely.

Now, turn the ignition to the “ON” position (but don’t start the engine). You’ll see the scanner power up. Most basic models will display “Scanning…” or “Reading DTCs” (that’s Diagnostic Trouble Codes).

This step lets the scanner talk to your car’s computer and pull up any stored error codes. Even if you’ve already fixed the problem, the code may still be lingering in the system—which is why the light stays on.

Step 3: Read the Codes (Optional but Helpful)

Before resetting, take a quick look at what the scanner shows. It might display something like “P0455” (a common EVAP leak code) or “P0171” (fuel system too lean).

Knowing the code helps confirm whether the issue was truly resolved. For example, if you tightened your gas cap and the code was P0457, that’s a good sign. But if it’s still showing a misfire code after replacing spark plugs, you might need more work.

If you’re confident the problem’s fixed—or you just want to clear the light—move to the next step.

Step 4: Clear the Codes

On most OBD2 scanners, there’s a button labeled “Clear,” “Erase,” or “Reset.” Press it. The screen should say something like “Codes Cleared” or “DTCs Erased.”

That’s it! The check engine light should turn off within a few seconds. If it doesn’t, double-check that the scanner is properly connected and that you’re in the “ON” ignition position (not running).

Pro tip: Some scanners require you to confirm the reset with a “Yes” prompt. Just follow the on-screen instructions.

Step 5: Test Drive and Confirm

Start your engine. The light should stay off. Take your G35 for a short 5–10 minute drive—this lets the car’s computer run its initial self-checks.

If the light stays off, congratulations! You’ve successfully completed the how to reset check engine light Infiniti G35 2026 guide process.

But if it comes back on? Don’t panic. It could mean the original issue wasn’t fully resolved, or a new problem has appeared. In that case, re-scan the codes and consider a deeper diagnosis.

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve seen plenty of folks try to reset their check engine light the “easy” way—and end up frustrated. Here’s what I’ve learned:

Warning: Don’t just disconnect the battery to reset the light. While it might work temporarily, it also resets your ECU’s learned driving habits, which can cause rough idling or poor fuel economy for days. Plus, if the underlying issue isn’t fixed, the light will return—often within a few miles.

• Don’t ignore the root cause. Resetting the light doesn’t fix the problem—it just hides it. Always address the issue first (e.g., replace a faulty oxygen sensor, tighten the gas cap).
• Use a quality OBD2 scanner. Cheap knockoffs sometimes fail to communicate properly with Infiniti systems. Look for brands like BlueDriver, FIXD, or Autel—they’re reliable and user-friendly.
• Check for pending codes. Even after clearing, some scanners show “pending” codes. These indicate the car hasn’t completed its drive cycle yet. A short drive usually clears them.
• Keep your scanner handy. Once you own one, you’ll find it useful for everything from monitoring fuel efficiency to diagnosing weird noises.

FAQs About How to Reset Check Engine Light Infiniti G35 2026 Guide

Q: Will resetting the check engine light pass an emissions test?
A: Not immediately. After a reset, your car needs to complete a “drive cycle”—a series of specific driving conditions—to re-run its self-tests. Most states won’t pass you until all monitors are “ready.” Plan a 20–30 minute drive mix of city and highway speeds before your test.

Q: Can I reset the light without an OBD2 scanner?
A: Technically, yes—but it’s not recommended. Some people try disconnecting the battery for 10–15 minutes, but this risks losing radio settings and doesn’t guarantee a clean reset. The scanner method is faster, safer, and more reliable.

Q: Why did my check engine light come back on after resetting?
A: Because the original problem still exists! The light is doing its job—alerting you to an issue. Re-scan the codes to see what’s triggering it again.

Q: Is it safe to drive with the check engine light on?
A: It depends. A steady (not flashing) light usually means a moderate issue—like a loose gas cap or minor sensor fault. You can drive short distances, but get it checked soon. A flashing light? That’s serious—stop driving and call a tow. It could mean engine misfires damaging the catalytic converter.

Q: Does the 2026 Infiniti G35 have any special reset procedures?
A: Not really. The OBD2 system is standardized across all modern vehicles, including the 2026 G35. The same steps apply. Just ensure your scanner supports newer protocols (most do).

Q: Can I use my smartphone instead of a scanner?
A: Yes—if you have a Bluetooth OBD2 adapter (like FIXD or OBD Fusion) and a compatible app. It’s convenient, but make sure your phone stays charged during the process!

Final Thoughts

Resetting the check engine light on your Infiniti G35 doesn’t have to be scary or expensive. With a simple OBD2 scanner and about five minutes, you can clear that pesky warning and get back to enjoying your ride.

Remember: the light is your car’s way of saying, “Hey, something’s up.” Don’t silence it without understanding why it turned on in the first place. Use this how to reset check engine light Infiniti G35 2026 guide as your go-to resource—not just to turn off the light, but to stay informed and proactive about your vehicle’s health.

Next time that little orange icon glows, you’ll know exactly what to do. And hey—you might even impress your friends at the next car meet.
