Why the Check Engine Light Comes On
Before we dive into how to reset the check engine light, it’s important to understand why it turns on in the first place. The check engine light—also known as the Malfunction Indicator Lamp (MIL)—is part of your car’s onboard diagnostic system (OBD2). It monitors engine performance, emissions, and other critical systems.
When the car’s computer detects a problem—like a faulty oxygen sensor, loose gas cap, or misfiring engine—it stores a trouble code and turns on the light. This doesn’t always mean a major repair is needed. Sometimes, it’s as simple as tightening the gas cap.
However, ignoring the light can lead to reduced fuel efficiency, increased emissions, or even engine damage. That’s why it’s crucial to diagnose the issue before attempting to reset the light.
Tools You’ll Need
To reset the check engine light on your 2014 Chrysler 200, you’ll need a few basic tools. The most effective method uses an OBD2 scanner, but we’ll also cover alternatives.
OBD2 Scanner
This is the best tool for the job. An OBD2 scanner plugs into your car’s diagnostic port and reads trouble codes. Many models also allow you to clear codes and reset the check engine light. Look for a scanner that’s compatible with Chrysler vehicles and offers code definitions (not just numbers).
Basic Hand Tools
If you plan to disconnect the battery, you’ll need a wrench or socket set to remove the negative terminal. Most Chrysler 200 models use a 10mm bolt.
Safety Gear
Always wear safety glasses when working under the hood. Disconnecting the battery can cause small sparks, so avoid loose clothing or jewelry.
Owner’s Manual
Your 2014 Chrysler 200 owner’s manual contains useful information about the OBD2 port location, fuse box, and reset procedures. Keep it handy.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most reliable way to reset the check engine light is with an OBD2 scanner. This method ensures you’ve addressed the root cause and gives you full control over the reset process.
Step 1: Locate the OBD2 Port
The OBD2 port in your 2014 Chrysler 200 is located under the dashboard, near the driver’s side knee panel. It’s a 16-pin connector, usually black or gray, and shaped like a trapezoid. You may need to crouch down or use a flashlight to find it.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s fully seated. Some scanners have a locking mechanism—press it in until it clicks.
Step 3: Turn on the Ignition
Turn the key to the “ON” position (but don’t start the engine). This powers the car’s computer and allows the scanner to communicate with it.
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to read the stored trouble codes. Most scanners will display a code like “P0420” or “P0171.” Write these down or take a photo for reference.
Step 5: Research the Codes
Use the scanner’s built-in database or search online to understand what each code means. For example, P0420 usually indicates a problem with the catalytic converter, while P0171 suggests a lean fuel mixture.
Step 6: Fix the Underlying Issue
Before resetting the light, make sure the problem is resolved. Replace a faulty sensor, tighten the gas cap, or repair a vacuum leak. If you’re unsure, consult a mechanic.
Step 7: Clear the Codes
Once the issue is fixed, use the scanner to clear the trouble codes. On most devices, this is done by selecting “Erase Codes” or “Clear DTCs.” The scanner will send a command to the car’s computer to reset the check engine light.
Step 8: Verify the Reset
Turn off the ignition, wait 10 seconds, then turn it back on. The check engine light should be off. If it comes back on, the problem may not be fully resolved, or a new issue has occurred.
Pro Tips for Using an OBD2 Scanner
- Use a scanner with live data streaming to monitor sensor readings in real time.
- Some scanners can perform system tests, like checking the EVAP system or oxygen sensors.
- Keep your scanner updated with the latest software for accurate code definitions.
- If the light returns after a few days, recheck the codes—it could indicate an intermittent problem.
Method 2: Disconnecting the Battery
If you don’t have an OBD2 scanner, disconnecting the battery is a common alternative. This method forces the car’s computer to reset by cutting power. However, it comes with some drawbacks.
Step 1: Turn Off the Engine and Remove the Key
Make sure the car is completely off. Remove the key from the ignition to prevent any electrical surges.
Step 2: Locate the Battery
The battery in your 2014 Chrysler 200 is in the engine compartment, on the driver’s side. It’s housed in a black plastic case with a positive (+) and negative (-) terminal.
Step 3: Disconnect the Negative Terminal
Use a 10mm wrench or socket to loosen the nut on the negative terminal (marked with a “-” sign). Carefully remove the cable and tuck it away from the battery to prevent accidental contact.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the car’s computer (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 it’s snug but don’t overtighten—this can damage the terminal.
Step 6: Turn on the Ignition
Turn the key to the “ON” position and check if the check engine light is off. If it is, start the engine and let it idle for a few minutes.
Potential Issues with Battery Disconnection
- Radio and Clock Reset: You may need to re-enter your radio presets and reset the clock.
- Adaptive Learning Lost: The transmission and engine may need to relearn driving patterns, which can cause rough shifting or poor performance for a few days.
- Security System Issues: Some models may trigger the security light or require a key reprogramming procedure.
- Not Always Effective: If the underlying problem isn’t fixed, the light will likely come back on.
When to Avoid This Method
Don’t use battery disconnection if your car has advanced safety systems, like adaptive cruise control or lane departure warning. These systems may require professional recalibration after a power loss.
Method 3: Drive Cycle Reset
Sometimes, the check engine light will turn off on its own after the car’s computer rechecks the systems. This is called a “drive cycle.” It’s a series of driving conditions that allow the OBD2 system to run self-tests.
What Is a Drive Cycle?
A drive cycle is a specific pattern of driving that includes cold starts, highway speeds, and deceleration. The car’s computer uses this to verify that repairs were successful and that emissions systems are working properly.
Typical Drive Cycle for 2014 Chrysler 200
- Start the engine when it’s cold (hasn’t been run for at least 8 hours).
- Let it idle for 2–3 minutes.
- Drive at 30–40 mph for 5 minutes.
- Accelerate to 55–60 mph and maintain speed for 10 minutes.
- Decelerate slowly (without braking hard) to 20 mph.
- Stop and idle for 2 minutes.
- Repeat the cycle 2–3 times over several days.
How Long Does It Take?
Most drive cycles take 30–60 minutes of driving. The check engine light may turn off after one complete cycle, or it may take several days of normal driving.
Limitations of Drive Cycles
- Only works if the problem is truly fixed.
- Not effective for hard codes (persistent issues).
- May not reset all monitors—some systems require specific conditions.
