How to Clear the Engine Light from Chrysler 2013

If you own a 2013 Chrysler and the dreaded check engine light has popped up on your dashboard, don’t panic. While it can be alarming, the light is simply your car’s way of saying, “Hey, something needs attention.” The good news? You can often clear it yourself—safely and easily—with the right tools and knowledge.

In this guide, you’ll learn how to clear the engine light from a 2013 Chrysler step by step. We’ll cover why the light comes on, the best tools to use, and what to do if it returns. Whether you’re a DIY enthusiast or just want to save a trip to the mechanic, this guide has you covered.

Why Is the Engine Light On?

Before you clear the light, it’s important to understand why it turned on in the first place. The engine light, also known as the malfunction indicator lamp (MIL), can signal anything from a minor issue to a serious engine problem.

Common causes in a 2013 Chrysler include:

  • A loose or faulty gas cap
  • A failing oxygen (O2) sensor
  • Worn spark plugs or ignition coils
  • Catalytic converter issues
  • Mass airflow (MAF) sensor problems
  • Evaporative emissions system leaks

Ignoring the light—or clearing it without fixing the root cause—can lead to reduced fuel efficiency, engine damage, or even failure to pass emissions tests. So always diagnose first.

Tools You’ll Need

To clear the engine light on your 2013 Chrysler, you’ll need one of the following:

  • An OBD2 scanner (also called a code reader)
  • A smartphone with an OBD2 app and Bluetooth adapter
  • Access to a mechanic’s scan tool (if you go the professional route)

An OBD2 scanner is the best option for most drivers. These devices plug into your car’s diagnostic port and read trouble codes. Many are affordable—under $30—and easy to use. Look for models with “clear codes” or “reset” functions.

Step-by-Step: How to Clear the Engine Light

Step 1: Locate the OBD2 Port

In your 2013 Chrysler, the OBD2 port is usually under the dashboard on the driver’s side. It’s a 16-pin connector, often near the steering column. You might need to crouch down or use a flashlight to find it. It’s typically black and shaped like a trapezoid.

Step 2: Plug in the OBD2 Scanner

Turn off the ignition, then plug the scanner into the OBD2 port. Make sure it’s fully inserted. Some scanners have a light that turns on when connected properly.

Step 3: Turn the Ignition to “On”

Don’t start the engine—just turn the key to the “on” position (or press the start button without pressing the brake). This powers up the car’s electrical system so the scanner can communicate with the engine control unit (ECU).

Step 4: Read the Trouble Codes

Press the “Read” or “Scan” button on your OBD2 device. It will display one or more trouble codes, like P0420 or P0171. These codes tell you what system is having trouble.

Write down the codes. You can look them up online or use the scanner’s built-in code library to understand what they mean. For example, P0420 often points to a catalytic converter issue, while P0171 means the engine is running too lean.

Step 5: Fix the Underlying Issue (If Possible)

Before clearing the light, try to fix simple problems. For example:

  • If the code is P0455 or P0457, check your gas cap. Tighten it or replace it if it’s cracked.
  • If it’s a P0300 (random misfire), inspect spark plugs or coils.

Some issues, like a failing oxygen sensor, may require professional repair. But if you’ve fixed the problem—or if you’re sure it’s minor—you can proceed to clear the light.

Step 6: Clear the Engine Light

On your OBD2 scanner, look for a button labeled “Clear,” “Erase,” or “Reset.” Press it. The scanner will send a command to the ECU to turn off the engine light.

Wait a few seconds. The scanner should display a message like “Codes cleared” or “System reset.” Then turn off the ignition and unplug the scanner.

Step 7: Start the Engine and Check

Turn the key to start the engine. The check engine light should be off. If it stays off, great! You’ve successfully cleared it.

If the light comes back on within a few minutes or after driving, the problem wasn’t fully resolved. The ECU has detected the same issue again.

Alternative Method: Disconnecting the Battery

If you don’t have an OBD2 scanner, you can try clearing the engine light by disconnecting the car battery. This method resets the ECU, which may turn off the light—but it’s not always reliable and comes with risks.

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: Disconnect the Negative Battery Terminal

Use a wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away so it doesn’t touch the battery post.

Step 3: Wait 15–30 Minutes

This gives the ECU time to fully reset. Some sources recommend waiting up to an hour for older vehicles, but 15–30 minutes is usually enough for a 2013 Chrysler.

Step 4: Reconnect the Battery

Reattach the negative terminal and tighten it securely. Make sure it’s snug but don’t overtighten.

Step 5: Start the Engine

Turn the key and start the car. The engine light may be off—but again, this doesn’t guarantee the problem is fixed.

Important Note: Disconnecting the battery can reset other systems, including your radio presets, clock, and anti-theft settings. Some Chrysler models may also require a radio code to reactivate the audio system. Check your owner’s manual for details.

What to Do If the Light Comes Back

If the engine light returns after clearing it, don’t ignore it. This means the underlying issue is still present. Here’s what to do:

  • Re-scan for trouble codes to see if the same code appears.
  • Check for obvious issues like a loose gas cap or damaged wiring.
  • Monitor your car’s performance—does it run rough, hesitate, or use more fuel?
  • Take it to a trusted mechanic for a full diagnostic.

Some problems, like a failing catalytic converter, can cause serious damage if left unchecked. A professional can run advanced tests and recommend the right repair.

Tips for Preventing Future Engine Light Issues

Once you’ve cleared the light, take steps to avoid it coming back:

  • Always tighten your gas cap after refueling.
  • Follow your maintenance schedule—replace spark plugs, air filters, and fluids on time.
  • Use quality fuel and avoid cheap gas stations.
  • Listen for unusual engine noises or performance changes.
  • Keep your OBD2 scanner handy for quick checks.

Regular maintenance is the best way to keep your 2013 Chrysler running smoothly and prevent unexpected dashboard warnings.

When to See a Mechanic

While many engine light issues can be handled at home, some require professional help. See a mechanic if:

  • The light is flashing (this indicates a severe misfire that can damage the catalytic converter).
  • You’re getting multiple trouble codes.
  • The car is running poorly, overheating, or losing power.
  • You’re unsure how to interpret the codes or fix the problem.

A certified technician has advanced tools and training to diagnose complex issues quickly and accurately.

Final Thoughts

Clearing the engine light on your 2013 Chrysler doesn’t have to be scary or expensive. With an OBD2 scanner and a little know-how, you can safely reset the light after addressing the root cause. Just remember: the light is there for a reason. Always diagnose the problem first, and don’t ignore recurring warnings.

By following this guide, you’ll save time, money, and stress—and keep your Chrysler running at its best.
