Before we dive into resetting the light, it’s important to understand why it came on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, and various sensors.
In the 2008 Chrysler Sebring, common triggers include:
– Loose or faulty gas cap
– Oxygen (O2) sensor failure
– Mass airflow (MAF) sensor issues
– Catalytic converter problems
– Spark plug or ignition coil malfunctions
– Exhaust gas recirculation (EGR) valve clogging
The light can appear as either a steady glow or a flashing signal. A steady light usually means a minor issue, while a flashing light indicates a serious problem that could damage the engine or catalytic converter if ignored.
Should You Reset the Light Immediately?
No—don’t reset the light until you’ve diagnosed and fixed the problem. Resetting it without addressing the root cause is like turning off a smoke alarm while a fire still burns. The light will likely return, and you could miss a critical issue.
Here’s what to do first:
1. Scan for trouble codes: Use an OBD2 scanner to read the diagnostic trouble codes (DTCs). These codes tell you exactly what system or component is malfunctioning.
2. Research the code: Look up the code (e.g., P0420 or P0171) online or in a repair manual to understand the issue.
3. Repair or replace the faulty part: Whether it’s tightening the gas cap or replacing an O2 sensor, fix the problem before resetting.
Only after the repair should you proceed to reset the check engine light.
Method 1: Reset Using an OBD2 Scanner (Recommended)
The safest and most effective way to reset the check engine light on a 2008 Chrysler Sebring is with an OBD2 scanner. This tool communicates directly with your car’s computer and clears trouble codes without affecting other systems.
What You’ll Need
– OBD2 scanner (Bluetooth, handheld, or code reader)
– 2008 Chrysler Sebring (engine off)
– Owner’s manual (optional, for reference)
Step-by-Step Instructions
Step 1: Locate the OBD2 Port
The OBD2 port in the 2008 Chrysler Sebring is usually found under the dashboard on the driver’s side. It’s a 16-pin connector, often near the steering column. You may need to crouch down or use a flashlight to spot it.
Tip: If you can’t find it, check behind a small panel or under the steering wheel. Some models have it tucked behind the fuse box cover.
Step 2: Plug in the OBD2 Scanner
Turn the ignition to the “ON” position (but don’t start the engine). This powers up the vehicle’s electrical system without engaging the engine.
Plug the OBD2 scanner into the port. Most scanners will light up or display a welcome message once connected.
Step 3: Turn On the Scanner
Follow the scanner’s instructions to power it on. If it’s a Bluetooth model, pair it with your smartphone and open the companion app (e.g., Torque Pro, OBD Fusion).
Step 4: Read the Trouble Codes
Select “Read Codes” or “Scan” from the menu. The scanner will retrieve any stored DTCs. Write down the codes (e.g., P0455 for a large EVAP leak) for reference.
Example: If you see P0133, it means the O2 sensor circuit is responding too slowly. This could indicate a dirty or failing sensor.
Step 5: Clear the Codes
Once you’ve confirmed the issue has been repaired, select “Clear Codes” or “Erase DTCs.” The scanner will send a command to the car’s computer to reset the check engine light.
You should see a confirmation message like “Codes Cleared” or “Reset Successful.”
Step 6: Turn Off the Ignition
Wait about 10–15 seconds, then turn the ignition back to “OFF.” Unplug the scanner.
Step 7: Start the Engine
Start your Sebring. The check engine light should be off. If it remains off after driving for a few minutes, the reset was successful.
Pro Tip: Some scanners also allow you to view live data, freeze frame data, and monitor readiness monitors—useful for emissions testing.
Advantages of Using an OBD2 Scanner
– Precise and reliable
– Preserves radio presets and adaptive learning
– Allows you to read and interpret codes
– Reusable for future diagnostics
– Affordable (basic models start under $20)
Method 2: Reset by Disconnecting the Battery
If you don’t have an OBD2 scanner, you can reset the check engine light by disconnecting the car battery. This method forces the vehicle’s computer to reset, clearing stored codes and turning off the light.
Warning: This method can erase radio settings, clock, seat memory, and adaptive transmission learning. Use it only if other options aren’t available.
What You’ll Need
– Wrench or socket set (usually 10mm)
– Safety gloves and glasses
– 2008 Chrysler Sebring (parked, engine off)
Step-by-Step Instructions
Step 1: Turn Off the Engine and Remove the Key
Make sure the car is completely off and the key is out of the ignition.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2008 Sebring, it’s typically on the driver’s side of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench to loosen the nut on the negative (-) battery terminal. Carefully remove the cable and tuck it away from the battery to prevent accidental contact.
Safety Tip: Always disconnect the negative terminal first to avoid short circuits.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer (ECU) to fully discharge and reset.
Some experts recommend up to 30 minutes for a complete reset, especially if the car has advanced electronics.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure the connection is snug to avoid voltage drops.
Step 6: Start the Engine
Turn the ignition to “ON” and wait a few seconds. Then start the engine. The check engine light should be off.
You may notice the radio asking for a code or the clock reset to 12:00. Refer to your owner’s manual to restore settings.
When This Method Works Best
– After a minor repair (e.g., gas cap replacement)
– When you don’t have access to an OBD2 scanner
– For older vehicles with simpler electronics
Limitations and Risks
– May not clear all codes permanently
– Can reset adaptive learning (e.g., transmission shift points)
– Risk of electrical shorts if done improperly
– Some systems may require relearning procedures
Method 3: Drive Cycle Reset (Passive Method)
In some cases, the check engine light will turn off on its own after the problem is fixed and the vehicle completes a series of driving conditions known as a “drive cycle.”
This method doesn’t actively reset the light but allows the car’s computer to confirm the issue is resolved.
What Is a Drive Cycle?
A drive cycle is a specific sequence of driving conditions that allows the OBD2 system to run self-tests. Once all tests pass, the computer turns off the check engine light.
Typical Drive Cycle for 2008 Chrysler Sebring
Follow these steps to complete a basic drive cycle:
1. Start the engine cold: Let the car sit overnight so the engine is at ambient temperature.
2. Idle for 2–3 minutes: Let the engine warm up without driving.
3. Drive at 30–40 mph for 5 minutes: Maintain steady speed on a flat road.
4. Accelerate to 55 mph and cruise for 10 minutes: Keep speed consistent.
5. Decelerate without braking: Let the car slow down naturally to 20 mph.
6. Stop and idle for 2 minutes: Turn off the engine.
After completing this cycle, the computer may run emissions and sensor tests. If all pass, the check engine light should turn off.
How Long Does It Take?
It can take 3–7 days of normal driving for the light to turn off automatically, depending on how often you drive and the conditions.
Note: This method only works if the original problem is truly fixed. If the issue persists, the light will return.
Troubleshooting Common Reset Issues
Even after resetting, the check engine light may come back on. Here’s how to troubleshoot:
Light Comes Back On Immediately
– The problem wasn’t fixed.
– A new issue has occurred.
– The repair was incomplete (e.g., gas cap tightened but not fully sealed).
Light Returns After a Few Days
– Intermittent fault (e.g., loose wiring, failing sensor).
– Drive cycle not completed.
– Emissions system still failing tests.
Radio or Clock Resets After Battery Disconnect
– Normal behavior. Re-enter radio code (found in owner’s manual or glove box).
– Reset clock and seat positions.
Scanner Won’t Connect
– Check OBD2 port for damage or corrosion.
– Ensure ignition is in “ON” position.
– Try a different scanner or update firmware.
“Codes Not Clearable” Message
