Restore Peak Performance to Your GM Vehicle
Is your 2006 Chevrolet Uplander, or another compatible GM vehicle, suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM), the brain of your engine, is often the culprit behind problems like erratic idling, poor fuel economy, stalling, or a persistent Check Engine Light. In my 20+ years as a technician, I’ve seen firsthand how a failing PCM can turn a reliable vehicle into a source of constant worry. This isn’t just an inconvenience; it affects your vehicle’s safety, emissions, and overall drivability.
We offer a dependable and straightforward solution: a replacement Powertrain Control Module, part number 19210070 (also compatible with service number 12600928). The critical advantage we provide is our professional VIN programming service. Before we ship the part, we flash it with the latest official GM software updates tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures seamless integration and optimal performance, eliminating the need for an expensive trip to the dealership for programming. You get a part that’s ready to install right out of the box, restoring the precise control your engine needs to run smoothly and efficiently.
A Technician’s Notebook: The Intermittent Stall
A customer brought in a 2006 Pontiac G6 with the 3.5L engine, complaining of a problem that drives mechanics crazy: intermittent stalling. It would die at stoplights, but only sometimes. No consistent codes were stored, just a history of random communication faults. We checked fuel pressure, ignition components, and wiring harnesses for hours. Everything seemed fine. Drawing on experience, I suspected the PCM was failing internally under specific thermal conditions. We swapped in a VIN-programmed module like this one, and the problem vanished instantly. The internal processor was faulting when it got hot, but not long enough to set a hard code like a P0606. This is a classic failure mode for these units, and a new, correctly programmed module is the only reliable fix.
Key Symptoms of a Failing PCM
- ✔ Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ Your vehicle fails to start or experiences hard starting conditions.
- ✔ Unexplained drops in fuel efficiency.
- ✔ The engine stalls, stumbles, or misfires unexpectedly.
- ✔ Noticeable hesitation or loss of power during acceleration.
- ✔ Automatic transmission shifts erratically or harshly.
- ✔ Failure to pass state emissions testing.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the Module: On most of these vehicles, the PCM is located in the left-hand (driver’s side) front engine compartment, often near the air filter housing.
- ✔ Disconnect Wiring: Carefully release the locking tabs on the electrical connectors and gently pull them straight out from the module. Never force them. Inspect connectors for any corrosion or damage.
- ✔ Remove the Old PCM: Unbolt the mounting hardware that secures the old PCM to its bracket or the vehicle body. Note the orientation of the module before removing it.
- ✔ Install the New PCM: Mount your new, pre-programmed module in the same position as the old one and secure it with the original hardware.
- ✔ Reconnect and Finalize: Firmly press the electrical connectors into the new PCM until they click into place. Reconnect the negative battery terminal. Your vehicle may need to complete a drive cycle for all systems to fully sync.
By choosing this professionally programmed 2006 Uplander Powertrain Control Module, you are not just buying a part; you are investing in a reliable, long-term solution that restores your vehicle’s factory-specified operation. It’s the smart, efficient way to get back on the road with confidence.

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. We program the module to the VIN you provide before shipping. It arrives ready for installation. In some cases, a security or CASE relearn procedure may be required with a capable scan tool, but the core engine operating software will be fully loaded.

After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct software for your specific vehicle.
Is this a new or used part?
This is a high-quality, inspected, and tested replacement part that has been professionally programmed with the latest GM software updates to ensure reliability and performance.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM also controls transmission functions like shift points and line pressure. If the PCM is faulty, it can cause erratic shifting, which a replacement module will correct.
Where is the PCM located on my 2006 Uplander?
On the 2006 Uplander with the 3.5L engine, the Powertrain Control Module is typically found in the engine compartment on the driver’s side (LH side), near the air filter box or firewall.
