Is Your Dodge or Chrysler Running Rough?
There’s nothing more frustrating than a vehicle that won’t perform as it should. If your 2009 Dodge Challenger, or a compatible Charger, 300, or Magnum, is experiencing perplexing issues like stalling, a persistent check engine light, or a complete no-start condition, the root cause is often the very brain of the operation: the Engine Control Module (ECM). A failing ECM can disrupt everything from fuel delivery and ignition timing to transmission shifting, leaving you with an unreliable and unsafe vehicle. This replacement Engine Control Module, part number 5150246AD, is the definitive solution to restore your vehicle’s health and your peace of mind.
I remember a 2010 Dodge Charger with the 3.5L V6 that came into the shop with an intermittent stalling problem that was driving the owner crazy. It would die at stoplights, but then start right back up. We checked the fuel pump, throttle body, and all the usual suspects, but every test came back clean. No specific codes were being stored, just a generic U-code for lost communication every so often. After hours of chasing wires, we decided to monitor the ECM’s data stream during a drive. We noticed the 5-volt reference signal would momentarily drop out just before a stall. We swapped in a known-good ECM, and the problem vanished. The original computer had an internal fault that only showed up when it was hot. It’s a classic case of how a failing ECM can mimic a dozen other problems, and why a quality, tested replacement is so critical.

Frequently Asked Questions
Is this engine computer truly Plug and Play?
Yes, absolutely. We program the module to your specific VIN and mileage before it ships. This ensures it communicates perfectly with your vehicle’s existing systems, including the anti-theft immobilizer, without any need for a trip to the dealer for further programming.
How do I provide my VIN and mileage for programming?
After you place your order, you will be prompted to provide your vehicle’s VIN and current mileage. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the computer that controls only engine functions. A PCM (Powertrain Control Module) controls both the engine and the transmission. For this specific vehicle application, this unit functions as the primary engine controller.
Will this fix my car’s specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, it’s crucial to have your vehicle properly diagnosed by a qualified mechanic to rule out other potential causes, such as faulty sensors or wiring issues, before ordering.
Where is the ECM located on my 2009 Challenger?
The Electronic Control Module is located in the engine bay, on the driver’s side (LH side) toward the front of the vehicle. It is typically a silver metal box with several large electrical connectors.
