Restore Peak Performance to Your GM Vehicle
Is your Buick Park Avenue, Pontiac Grand Prix, or Chevrolet Impala suffering from frustrating issues like stalling, a persistent check engine light, or a no-start condition? The Powertrain Control Module (PCM), the electronic brain of your engine, is often the root cause of these perplexing problems. This replacement PCM, compatible with part numbers 12210234 and 12209624, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike a standard part from a salvage yard, this module isn’t just a piece of hardware. We provide a comprehensive service by programming the unit specifically to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures that the PCM has the correct factory calibrations for your engine, transmission, and emissions equipment. It’s loaded with the newest software updates from GM, addressing common issues and optimizing performance beyond the original factory state. This process eliminates compatibility problems and ensures a seamless integration with your car’s systems.
From the Diagnostic Bay
We once had a 2002 Buick LeSabre come in with an intermittent stalling problem and a host of random sensor codes (TPS, MAF, O2). The owner had already replaced three different sensors with no success. After confirming the sensors and wiring were good, we hooked up a scope to the PCM’s 5-volt reference circuit. We saw the voltage drop out unpredictably, causing the sensors to give false readings. The issue wasn’t the sensors themselves, but the failing PCM that powered them. A properly programmed replacement module solved all the issues in one go, saving the customer from any more wasted time and money on parts they didn’t need.

- ✔ Vehicle refuses to start, even with a good battery and starter.
- ✔ Noticeable decrease in fuel economy.

This module is a direct fit for a wide range of popular GM vehicles equipped with the legendary 3.8L engine. Please verify your original part number and consult the fitment list to ensure compatibility with your specific make, model, and year.
Frequently Asked Questions
Do I need to have this PCM programmed?
No. The main benefit of our service is that we program the module for you before it ships. All you need to do is provide your vehicle’s VIN during the checkout process or by contacting us after your purchase.
Is this a simple plug-and-play installation?
It is a direct physical fit and electronically programmed for your car. However, you will need to perform a security relearn procedure after installation. This procedure pairs the new PCM to your vehicle’s anti-theft system and is required for the engine to start. Instructions for this are widely available online or in service manuals.
My original part number is 12209624. Will this part work?
Yes, this listing is for a module that serves as a direct replacement for both part numbers 12210234 and 12209624. We will ensure the programming is correct for your vehicle regardless of which of these two numbers you have.
How do I provide my VIN?
You can enter your VIN in the notes section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship your part.
Will this fix my car’s problem?
If your vehicle’s issues have been correctly diagnosed as a faulty PCM, this part will resolve them. It’s crucial to ensure the PCM is the actual point of failure, as other issues like bad wiring or faulty sensors can sometimes mimic PCM symptoms.
