Is your Chevy Cobalt or HHR running rough, stalling, or showing a persistent check engine light? A faulty Engine Control Module (ECM) can be incredibly frustrating, leaving you with an unreliable vehicle that you can’t depend on. This VIN-programmed replacement PCM is the definitive solution to restore your car’s performance and your peace of mind. Stop guessing and replace the core of your vehicle’s engine management system with a unit that’s ready to install right out of the box.
Common Symptoms & Your Direct-Fit Solution
If you’re experiencing issues like a harsh or erratic idle, poor acceleration, decreased fuel economy, or random stalling, your PCM is the likely culprit. A failing module can also trigger a host of confusing check engine light codes, such as P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault). Our module is the answer. We take a quality, fully tested unit and flash it with the latest official GM software updates, precisely matched to your vehicle using its unique Vehicle Identification Number (VIN). This ensures perfect communication between the engine, transmission, and all related systems, restoring the smooth, reliable operation you expect. This is the most effective way to address issues stemming from a bad computer and is a crucial step in any proper diagnosis of a Programmed 2005-2006 Cobalt PCM failure.

An Expert’s Note on Programming: Many people don’t realize that a PCM is more than just hardware; it’s the brain of your car. Installing an unprogrammed module is like putting a brain in that doesn’t know how to speak the car’s language. It can lead to transmission shifting problems, security system lockouts, and a car that runs worse than before. That’s why we insist on pre-programming every single unit to your VIN. We handle the complex part so you can enjoy a simple, successful repair and get your reliable daily driver back on the road.
Frequently Asked Questions
Do I need to have this programmed by a dealer after I receive it?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes the installation process plug-and-play, saving you time and the high cost of dealership programming.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We cannot ship your part until we have this information, as it is essential for the programming process.
Is this the correct part for my Pontiac Pursuit or Chevy HHR?
Yes, this part is compatible with the 2005-2006 Pontiac Pursuit (2.2L) and the 2006 Chevrolet HHR (2.2L) as specified in the fitment guide. It is a direct replacement Programmed 2005-2006 Cobalt PCM that also fits these other GM models.
What is the difference between an ECM, PCM, and ECU?
These terms are often used interchangeably. ECU (Engine Control Unit) is a general term. ECM (Engine Control Module) typically controls only engine functions. PCM (Powertrain Control Module) controls both the engine and the transmission. For this vehicle, PCM is the most accurate term.
Will this fix my specific check engine light codes?
This module is a direct solution for codes related to internal processor failure (like P0601, P0606). While it can resolve many other issues, it’s crucial that your vehicle has been properly diagnosed. This part will not fix problems caused by faulty sensors or wiring.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty. This provides coverage against defects in the part itself, giving you confidence in your repair.
