Is Your 2007 Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is the central computer of your vehicle’s engine management system. When it begins to fail, it can cause a cascade of frustrating and seemingly unrelated issues. From poor fuel economy and hesitation to a complete no-start condition, a faulty PCM can leave you stranded and facing a costly diagnostic bill. This genuine used PCM, part number 19210736 (interchangeable with 12605843), is the reliable and cost-effective solution to restore your vehicle’s performance and dependability.
This isn’t just a part in a box. We provide a crucial service that sets our modules apart. Before this unit ships, we will program it with the latest GM-certified software updates specifically for your vehicle using the VIN you provide. This ensures that once installed, the computer is perfectly matched to your car’s engine, transmission, and options, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2007 Pontiac G6 come in with a persistent P0606 (Internal Control Module Processor Error) code. The owner had already replaced the throttle body and a couple of sensors, chasing what seemed to be a fuel delivery issue. The car would start but run erratically and stall intermittently. After confirming power and ground to the module were solid, we knew the issue was internal to the computer itself. Swapping in a VIN-programmed PCM like this one solved the problem instantly. The car ran smoothly, the code was gone, and the customer was saved from hundreds more in unnecessary parts and labor.
Solving Problems with the 2007 ION PCM
A failing 2007 ION PCM can manifest in many ways. This module is the key to getting your vehicle back on the road. By managing everything from fuel injection and ignition timing to transmission shift points, its proper function is critical. This replacement part is sourced from a salvaged vehicle and is ready to be the new brain for your engine, restoring its original operational parameters.
Common Symptoms of a Failing PCM
- ✔️ Check Engine Light is illuminated with various trouble codes (especially U-codes or P06xx codes).
- ✔️ Engine stalling or shutting off unexpectedly while driving.
- ✔️ Difficulty starting the engine or a complete no-start condition.
- ✔️ Noticeable decrease in fuel efficiency.
- ✔️ Poor engine performance, including hesitation, misfires, or rough idling.
- ✔️ Automatic transmission shifting erratically or harshly.
- ✔️ Communication errors with diagnostic scan tools.
Broad Compatibility Across the GM Lineup
While this is a perfect solution for a 2007 ION PCM, this versatile module was used across a wide range of General Motors vehicles in 2007. Please verify your original part number or consult the fitment list below. This part is a direct replacement for models such as the Pontiac Solstice, Saturn Sky, Chevy Impala SS, Cadillac DTS, GMC Acadia, and many more. Its wide application makes it a proven and reliable component.
Important Note: After purchasing, please send us your vehicle’s 17-digit VIN. This is absolutely necessary for us to program the module correctly before shipment. Failure to provide a VIN will result in shipping delays.
Do I need to do anything after I install this PCM?
In many cases, you may need to perform a security relearn procedure, also known as a Passlock or Passkey relearn. This allows your vehicle’s anti-theft system to recognize the new module. This procedure can typically be done without special tools and instructions can be found online. Some vehicles may also require a Crankshaft Position Sensor (CASE) relearn, which may require a capable scan tool.
What is the difference between a PCM and an ECM?
The terms are often used interchangeably. ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. A PCM controls both the engine and the transmission, while an ECM typically controls only the engine. For most modern vehicles like your 2007 model, the unit is a PCM.
Why is VIN programming so important?
The VIN tells the module everything about your specific vehicle: engine size, transmission type, emissions equipment, and other options. Without the correct programming, the engine may not start, the transmission may not shift correctly, and you will likely have a check engine light on. Our pre-programming service saves you this significant hassle.
Where is my VIN located?
You can find your 17-digit Vehicle Identification Number (VIN) on the driver’s side of the 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?
No, this is a high-quality, genuine used part that has been carefully sourced from a salvaged vehicle. Each unit is inspected to ensure it is fully functional and ready for programming and installation in your car.
