Is Your 2007 GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, erratic engine behavior, poor fuel mileage, or even a no-start condition in your 2007 Saturn Sky or other compatible GM vehicle, a failing Engine Control Module (ECM) is a very likely culprit. The ECM, also known as the Powertrain Control Module (PCM), is the central computer of your vehicle. It manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems.
Why Choose Our Programmed 2007 Saturn Sky ECM?
This isn’t just a replacement part; it’s a complete, plug-and-play solution. This is a genuine, used GM ECM, part number 19210736 (interchangeable with 12605843), that has been meticulously tested and is ready for service. The critical difference is our professional programming service. Before we ship the module, we flash it with the latest GM-certified software updates specifically for your vehicle using the VIN you provide. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
From the Diagnostic Bay
We recently had a 2007 Pontiac G6 2.4L in the shop with a classic case of ECM failure. The customer complained of intermittent stalling at stoplights and a check engine light with codes for random misfires and lost communication with the TCM. After verifying the wiring and sensors were good, we pinpointed the ECM. Instead of a costly new unit from the dealer, we sourced a quality used module like this one. We programmed it to the car’s VIN, performed a quick security relearn, and the G6 ran like it just rolled off the assembly line. This is the exact, reliable solution we offer you directly.
Common Symptoms of a Failing GM ECM
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start or intermittent starting issues
- ✔ Failure to communicate with OBD-II scan tools
- ✔ Performance issues like hesitation or lack of power
Simple Installation Process
Once you receive your pre-programmed module, the installation is straightforward for a DIY mechanic or any professional technician. Simply disconnect the vehicle’s battery, locate and unplug the old ECM, install the new one, and reconnect the battery. In many cases, the vehicle will start and run perfectly. Some GM vehicles may require a simple, key-on/key-off security relearn procedure, which can typically be done without any special tools. We provide clear instructions to make the process as smooth as possible.
This module is a direct-fit replacement for a wide variety of 2007 GM vehicles, including the Saturn Sky, Pontiac Solstice, Chevy Impala, Cadillac DTS, and many more. By providing your VIN, you guarantee that the 2007 Saturn Sky ECM you receive is perfectly configured for your vehicle’s specific options and systems.
Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. We program the module to your vehicle’s specific VIN before shipping. It arrives ready to be installed. Some vehicles may require a simple security relearn procedure, which does not require special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a new part?
This is a high-quality, fully tested, used OEM part sourced from a salvaged vehicle. This provides OEM reliability at a fraction of the cost of a new unit from a dealership.
What is the difference between an ECM and a PCM?
The terms are often used interchangeably. An ECM (Engine Control Module) specifically controls engine functions. A PCM (Powertrain Control Module) controls both the engine and the transmission. For most modern vehicles like the ones this part fits, it is technically a PCM, but ECM is a commonly used term.
Will this fix my vehicle’s problem?
This module will resolve issues directly caused by a faulty ECM/PCM. While the symptoms listed are common for ECM failure, it’s crucial to have your vehicle properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical issues.
