Restore Your Pontiac’s Performance and Reliability
If you’re dealing with frustrating issues like a persistent check engine light, erratic engine behavior, stalling, or a no-start condition in your Pontiac Pursuit, the root cause is often a failing Engine Control Module (ECM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty ECM can create a cascade of problems that are difficult to diagnose. This isn’t just a part; it’s the brain of your vehicle, managing everything from fuel mixture and ignition timing to transmission shifting. This replacement 2006 Pursuit Engine Control Module is the definitive solution to get your car running smoothly and reliably again.
We take the guesswork and hassle out of the repair. Unlike sourcing a module from a salvage yard, which comes with an unknown history and requires expensive dealer programming, this unit arrives at your door ready for installation. We flash it with the latest official GM software updates, specifically calibrated to your vehicle’s VIN. This ensures optimal performance, fuel efficiency, and seamless communication with all other vehicle systems right out of the box.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2006 Cobalt—which shares its platform with the Pursuit—that came into the shop with a laundry list of intermittent complaints. The owner was frustrated; he’d replaced sensors and spark plugs, but the car would still occasionally stumble, the transmission would shift hard, and the check engine light would pop on with a random communication code (U0100). After checking the wiring harnesses and grounds, we focused on the ECM. On the surface, it looked fine. But under load and once it heated up, the internal processor would intermittently fail. Swapping in a pre-programmed ECM like this one solved every single issue instantly. It’s a classic case where the central component was causing system-wide chaos.
Is Your Pontiac Showing These Signs?
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or various U-codes (Communication Errors).
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained drops in fuel economy.
- ✔ Stalling, stumbling, or hesitation during acceleration.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Apparent loss of spark or fuel injector pulse.
Your Straightforward Installation Guide
Installing your new 2006 Pursuit Engine Control Module is a manageable job for a DIYer with basic tools. The key is our pre-programming service, which eliminates the need for advanced scan tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to discharge.
- Locate the ECM: On the 2006 Pontiac Pursuit, the ECM is typically found in the left-hand (driver’s side) front of the engine compartment.
- Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the mounting hardware holding the old ECM in place and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original hardware.
- Reconnect and Finalize: Plug the electrical harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal. A security relearn procedure may be required, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.

How do I provide my VIN for programming?
After completing your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it’s essential for the programming process.
Is any additional programming needed after installation?
No. This ECM comes fully programmed to your vehicle’s VIN with the latest GM software. In most cases, it is a plug-and-play installation. Some vehicles may require a simple key relearn or security relearn procedure, which does not require special tools and instructions can be easily found online.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (like codes P0601-P0606), then yes, this part is the correct fix. However, you should always diagnose the codes to ensure there isn’t an external sensor or wiring issue causing the problem.
Is this a used part?
This is a high-quality, tested, and verified used OEM part that has been inspected for full functionality. We then program it with new, updated software, making it a reliable and cost-effective alternative to a brand-new dealer part.
My original part number isn’t 12607096, but it’s on the interchange list. Will it work?
Yes. The listed service numbers (12590032, 12602044, etc.) are all interchangeable and have been superseded by this module. As long as your original part number is on our list, this module is the correct replacement for your vehicle.
