Is Your 2003 Chrysler or Dodge Plagued by Engine Problems?
If you’re experiencing frustrating issues like stalling, a persistent check engine light, rough idling, or a no-start condition in your 2003 Dodge Intrepid, Chrysler Concorde, or 300M, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it begins to fail, it can cause a cascade of performance problems that can be difficult to diagnose and can leave you stranded.
Don’t let a faulty computer dictate your vehicle’s reliability. This replacement ECM is the definitive solution to restore your vehicle’s performance and get you back on the road with confidence. It is meticulously prepared and programmed specifically for your vehicle, ensuring a seamless and straightforward installation process.
Expert Pro Tip
Before replacing your ECM, always perform a thorough check of the vehicle’s battery, alternator, and all primary ground connections. A weak battery or a poor ground strap (especially the main engine-to-chassis ground) can cause voltage fluctuations that mimic the symptoms of a failing ECM. A few minutes with a multimeter can save you from replacing a part that isn’t faulty.
Diagnosing a Faulty 2003 Intrepid ECM
The Engine Control Module in your 3.5L V6-powered vehicle is a sophisticated piece of hardware. Over time, heat cycles, vibrations, and electrical stress can cause internal components to fail. Recognizing the signs early can save you time and money. This replacement 2003 Intrepid ECM is engineered to resolve these exact issues, providing a stable and reliable command center for your engine.
Common Symptoms of ECM Failure
- ✔ Check Engine Light: The light may be on constantly or intermittently, often with communication-related trouble codes (U-codes) or multiple, seemingly unrelated sensor codes.
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or when coming to a stop.
- ✔ No-Start Condition: The engine cranks but refuses to start, even with good fuel pressure and spark.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG can indicate the ECM is not managing the fuel mixture correctly.
- ✔ Rough Idle or Misfires: The ECM controls the ignition coils and fuel injectors. A failure can lead to erratic idling or cylinder misfires.
- ✔ Automatic Transmission Issues: The ECM works with the transmission controller, and a fault can cause harsh shifting, failure to shift, or incorrect gear selection.
The Plug & Play Advantage
One of the biggest hurdles in replacing an engine computer on these Chrysler platform vehicles is programming. The module must be programmed with your vehicle’s unique Vehicle Identification Number (VIN) and configured to work with the factory anti-theft system (SKIM). Our service eliminates this completely. We flash this module with your car’s specific data before it ships. When you receive it, the installation is simple:
- Disconnect the vehicle’s battery.
- Locate the original ECM in the left-hand (driver’s side) front of the engine compartment.
- Unplug the electrical connectors and unbolt the module.
- Install the new module, reconnect the connectors, and re-bolt it in place.
- Reconnect the battery.
That’s it. No expensive trips to the dealership for programming, no special tools required. Your vehicle will start and run just as it should. This is the most efficient way to get your car running right again.

Frequently Asked Questions
What information do you need to program this ECM for my car?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can provide this information during the checkout process. This ensures the module is a perfect match for your car’s software and security settings.
Is this module truly Plug & Play?
Yes. Because we program the module to your specific VIN before shipping, it arrives ready for installation. You will not need to take your vehicle to a dealership or mechanic for additional programming. Simply install the part, and you’re ready to go.
Where is the ECM located on my 2003 Intrepid, Concorde, or 300M?
The Engine Control Module is located in the engine bay, on the driver’s side (LH side) near the front of the vehicle, typically close to the air filter box and shock tower.
How can I be certain my old ECM is the problem?
While the symptoms listed are strong indicators, professional diagnosis is the only way to be 100% certain. Common diagnostic steps include checking for communication with a scan tool, verifying power and ground signals at the ECM connector, and ruling out other potential causes like faulty sensors or wiring.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM plays a critical role in controlling the automatic transmission. If the module is faulty, it can send incorrect signals, leading to poor shifting performance. Replacing a bad ECM often resolves these related transmission issues.
