Is Your 2013 Avenger or 200 Running Poorly? The ECM Might Be the Culprit.
The Engine Control Module (ECM), also known as the engine computer, is the electronic brain of your 2013 Dodge Avenger or Chrysler 200. It meticulously manages everything from fuel injection and ignition timing to transmission shifts and emissions controls. When this critical component begins to fail, it can cause a cascade of confusing and frustrating problems that can be difficult to diagnose. You might experience erratic engine behavior, a sudden drop in fuel economy, or even a complete no-start condition, leaving you stranded. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2013 Avenger come into the shop with a classic intermittent stalling problem. The owner had already replaced the crankshaft position sensor and the throttle body based on some generic advice, but the issue persisted. After connecting our diagnostic scanner, we noticed erratic data readings from multiple sensors that didn’t make sense together. The voltage references were fluctuating slightly, a tell-tale sign that the ECM’s internal voltage regulator was failing. Instead of continuing to replace good parts, we focused on the source. A new, properly programmed 2013 Avenger Engine Computer solved the problem on the first try, saving the customer from further unnecessary expenses and headaches. It’s a powerful reminder that sometimes the problem lies with the component that reads the sensors, not the sensors themselves.
Symptoms of a Failing Engine Computer
- ✔ Check Engine Light is illuminated with various, often unrelated, trouble codes.
- ✔ Vehicle refuses to start or has difficulty starting, especially when warm.
- ✔ Stalling, stumbling, or hesitation during acceleration.
- ✔ Noticeable decrease in fuel efficiency for no apparent reason.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Misfire codes (like P0300-P0304) that persist after replacing plugs and coils.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Apparent failure of multiple sensors at once.

Simply disconnect the battery, swap the old module with this new one, reconnect the battery, and start your vehicle. Your car will be back to its factory-specified performance and reliability, restoring smooth operation and peace of mind.
Installation Overview
Replacing the ECM is a straightforward process for the competent DIY mechanic. While specific locations can vary slightly, the ECM is typically found in the engine bay, often near the battery or firewall.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all systems to discharge.
- Locate the ECM: Identify the existing engine computer. It will be a metal box with several large electrical connectors.
- Disconnect Connectors: Carefully release the locking tabs on the electrical harnesses and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM in place and secure the bolts.
- Reconnect Everything: Firmly plug the electrical connectors back into the new module until they click into place. Reconnect the negative battery terminal.
- Final Steps: Start the engine. The vehicle may run slightly rough for the first few minutes as the computer completes its internal self-checks and relearns idle parameters. Let it idle for 5-10 minutes before driving.
