Before you reset the light, it’s crucial to understand why it turned on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your car’s onboard diagnostics system (OBD2). This system constantly monitors sensors and components related to emissions, engine performance, and fuel efficiency.
On a 2016 Camaro SS, the light can illuminate for a wide range of reasons, from minor issues like a loose gas cap to more serious problems like a failing oxygen sensor or catalytic converter. Common triggers include:
– Loose or faulty gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Exhaust gas recirculation (EGR) valve malfunction
– Evaporative emissions system leaks
– Catalytic converter inefficiency
The key takeaway? The check engine light is a warning, not a diagnosis. Resetting it without fixing the root cause is like turning off a smoke alarm while your kitchen is still on fire. It might make you feel better temporarily, but the real problem remains.
That’s why the first step in any reset process should always be diagnosing the issue. Let’s walk through how to do that.
Step 1: Diagnose the Problem with an OBD2 Scanner
The most reliable way to understand why your check engine light is on is by using an OBD2 scanner. This small, handheld device plugs into your car’s OBD2 port and reads diagnostic trouble codes (DTCs) stored in the engine control unit (ECU).
Locate the OBD2 Port
On the 2016 Camaro SS, the OBD2 port is located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector, usually black or gray, and easy to spot once you know where to look. You don’t need any tools to access it—just reach under the dash and feel for the port.
Choose the Right Scanner
There are many OBD2 scanners on the market, ranging from basic code readers (under $20) to advanced Bluetooth models that connect to your smartphone (like the BlueDriver or FIXD). For most Camaro owners, a mid-range scanner with live data and code-clearing capabilities is ideal.
If you’re serious about maintaining your Camaro, investing in a quality scanner is worth it. It pays for itself after one or two uses, especially if you can avoid a trip to the mechanic.
Read the Trouble Codes
Once you’ve plugged in the scanner:
1. Turn the ignition to the “ON” position (but don’t start the engine).
2. Follow the scanner’s instructions to initiate a scan.
3. Wait for the device to retrieve the trouble codes.
The scanner will display codes like P0420 (catalytic converter efficiency below threshold) or P0171 (system too lean). These codes give you a starting point for diagnosing the issue.
Interpret the Codes
Most scanners come with a built-in code library or a companion app that explains what each code means. For example:
– P0455: Large evaporative emissions leak (often a loose gas cap)
– P0300: Random/multiple cylinder misfire detected
– P0133: O2 sensor circuit slow response (bank 1, sensor 1)
Use this information to research the likely cause and determine if it’s something you can fix yourself—like tightening the gas cap or replacing a sensor—or if you need professional help.
Clear the Codes (Temporarily)
After diagnosing the issue, you can use the scanner to clear the codes. This will turn off the check engine light—but only if the underlying problem is fixed. If you clear the codes without repairing the issue, the light will likely come back on after a few drive cycles.
Step 2: Fix the Underlying Issue
Now that you know what’s causing the check engine light, it’s time to fix it. Here are some common fixes for the 2016 Camaro SS:
Tighten or Replace the Gas Cap
A loose or damaged gas cap is one of the most common—and easiest—fixes. Simply remove the cap, inspect it for cracks or wear, and screw it back on until you hear it click. If the cap is damaged, replace it with an OEM or high-quality aftermarket part.
Replace a Faulty Oxygen Sensor
O2 sensors monitor the amount of oxygen in the exhaust and help the engine adjust the air-fuel mixture. A failing sensor can reduce fuel efficiency and increase emissions. On the Camaro SS, the upstream O2 sensor is located near the exhaust manifold and can be replaced with basic tools.
Clean or Replace the Mass Airflow Sensor
The MAF sensor measures how much air enters the engine. Dirt or oil buildup can cause inaccurate readings. Use a specialized MAF cleaner (never use regular spray cleaners) to gently clean the sensor. If it’s damaged, replacement is necessary.
Address Spark Plug or Ignition Coil Issues
Misfires often stem from worn spark plugs or failing ignition coils. The Camaro SS uses direct ignition, so each cylinder has its own coil. Replace spark plugs every 30,000–50,000 miles and coils as needed.
Check for Exhaust or Emissions Leaks
Use a smoke machine or have a mechanic perform a smoke test to detect leaks in the evaporative emissions system. Even a small leak can trigger the check engine light.
Once you’ve made the repair, it’s time to reset the light—properly.
Step 3: Reset the Check Engine Light Using an OBD2 Scanner
This is the most effective and recommended method for resetting the check engine light on your 2016 Camaro SS.
Plug in the Scanner
With the ignition on (engine off), plug the OBD2 scanner into the port under the dashboard.
Navigate to the Clear Codes Option
Use the scanner’s menu to find the “Clear Codes” or “Erase DTCs” option. Confirm the action when prompted.
Wait for Confirmation
The scanner will send a command to the ECU to erase the stored trouble codes. You should see a message like “Codes Cleared” or “Reset Successful.”
Turn Off the Ignition
Remove the scanner and turn off the ignition. The check engine light should now be off.
Start the Engine
Start your Camaro and verify that the light remains off. If it comes back on immediately, the problem wasn’t fully resolved, or a new issue has occurred.
Alternative Method: Disconnect the Battery
If you don’t have an OBD2 scanner, you can try resetting the check engine light by disconnecting the battery. This method forces the ECU to reset, but it’s not as reliable and can cause other issues.
Turn Off the Engine and Remove the Key
Make sure the car is off and the key is out of the ignition.
Locate the Battery
The 2016 Camaro SS has a battery in the trunk, on the driver’s side. Open the trunk and remove the cover to access it.
Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery post.
Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the ECU’s capacitors to discharge and reset the system.
Reconnect the Battery
Reattach the negative terminal and tighten the nut securely.
Start the Engine
Turn on the car and check if the check engine light is off. Note: This method may also reset other systems, like radio presets, clock, and adaptive transmission settings.
Alternative Method: Drive Cycle Reset
Some issues can be resolved simply by driving the car under specific conditions. This is called a “drive cycle,” and it allows the ECU to re-test systems and confirm that repairs were successful.
What Is a Drive Cycle?
A drive cycle is a series of driving maneuvers designed to trigger the OBD2 system’s self-tests. Once all tests pass, the check engine light may turn off automatically.
Typical Drive Cycle for 2016 Camaro SS
1. Start the engine and let it idle for 2–3 minutes (cold start).
2. Drive at 30–40 mph for 3–5 minutes.
3. Accelerate to 55–60 mph and maintain speed for 5–10 minutes.
4. Decelerate slowly without braking (coast in gear).
5. Repeat the cycle 2–3 times.
After completing the drive cycle, check if the light remains off. If it does, the issue may have been resolved. If not, further diagnosis is needed.
Troubleshooting Common Reset Issues
Even after following the steps above, you might run into problems. Here’s how to handle them:
The Light Comes Back On After Reset
This means the underlying issue wasn’t fixed. Re-scan for codes and double-check your repairs. Some problems, like catalytic converter failure, require professional attention.
The Light Flashes Instead of Staying Solid
A flashing check engine light indicates a severe misfire that can damage the catalytic converter. Stop driving immediately and have the car towed to a repair shop.
The Scanner Won’t Connect
Make sure the ignition is on, the scanner is compatible with OBD2, and the port isn’t damaged. Try a different scanner if possible.
Battery Disconnection Caused Other Issues
Reconnecting the battery may reset the radio, clock, or transmission settings. Use your owner’s manual to restore these features.
Tips for Preventing Future Check Engine Lights
An ounce of prevention is worth a pound of cure. Here’s how to keep your Camaro SS running smoothly:
