Restore Your Car’s Brain and Get Back on the Road
Is your Pontiac Pursuit, Chevy Cobalt, or Saturn Ion running rough, stalling unexpectedly, or flashing a persistent check engine light? These frustrating and often confusing issues frequently point to a failing Powertrain Control Module (PCM), the central computer of your vehicle. Don’t waste time and money replacing endless sensors. This is the direct, reliable solution to restore your car’s performance and your peace of mind. We provide a professionally programmed PCM, flashed with the latest official GM software and tailored specifically to your vehicle’s VIN number. It’s the closest you can get to a brand-new brain for your engine, without the dealership price tag.

- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- Poor Fuel Economy: A sudden and unexplained drop in your car’s gas mileage.

An Expert’s Note: We recently helped a customer with a 2005 Chevy Cobalt who was at his wit’s end. He had replaced the crank sensor, cam sensor, and even the fuel pump trying to solve a random stalling issue. The car would just die at red lights. After a quick consultation, we identified the PCM as the culprit. He ordered this exact module, we programmed it to his VIN, and he installed it in his driveway in under 30 minutes. The problem was instantly gone. It’s a reminder that sometimes the ‘brain’ is the issue, not the ‘body parts’, and getting the right 2005 Pontiac Pursuit PCM is the key to a lasting fix.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your car’s specific systems and features.
Is this module difficult to install?
For most of the compatible vehicles, the PCM is located in the left-front of the engine compartment and is very accessible. Installation typically requires basic hand tools to disconnect the battery, unbolt the module, and swap the electrical connectors. Most DIY mechanics can complete the job in under an hour.
Will I need to have a dealer do anything after installation?
No. Because we program the module to your VIN before shipping, it is ready for installation right out of the box. In some cases, a simple security relearn procedure (often called a ‘key relearn’) may be necessary, which can be done without any special tools. We can provide instructions for this common procedure.
How do I know if this will fit my car?
This module fits the specific models and years listed, including the 2005 Pontiac Pursuit, 2004-2005 Chevy Malibu (2.2L), 2005 Chevy Cobalt, and 2004-2005 Saturn Ion (2.0L). The best way to confirm is to match your existing part number to one of these: 12615197, 12589320, or 12579132.
What does the programming service include?
Our programming service uses your VIN to load the correct factory software and calibrations for your vehicle’s engine, transmission, and options. We also install the latest updates from GM to ensure your car runs as efficiently and reliably as possible with this new 2005 Pontiac Pursuit PCM.
