Restore Your Vehicle’s Brainpower and Performance
The Powertrain Control Module (PCM), often called the Electronic Control Module (ECM), is the central command center for your vehicle’s engine and transmission. It meticulously manages critical functions like fuel injection, ignition timing, emissions systems, and transmission shift points. When this vital component begins to fail in your 2006 Pontiac Montana or other compatible GM vehicle, it can lead to a cascade of frustrating and performance-robbing issues. This replacement PCM, part number 19210070, is the definitive solution to restore your vehicle’s factory performance, reliability, and efficiency.
The Critical Role of a Programmed 2006 Montana Powertrain Control Module
Unlike a simple mechanical part, a PCM is a sophisticated computer that must be precisely calibrated to your specific vehicle. This isn’t a one-size-fits-all component. Our process ensures a seamless installation by pre-programming the module to your vehicle’s unique Vehicle Identification Number (VIN). By providing us with your VIN at checkout, you receive a unit loaded with the latest official GM software updates. This addresses potential factory bugs and optimizes performance beyond the original specifications, ensuring perfect communication between the module and all your vehicle’s systems.
From the Diagnostic Bay
We had a 2006 Chevy Equinox come in with a problem that was baffling the owner. The vehicle would randomly stall at stoplights, the check engine light was intermittent, and the transmission would occasionally shift harshly. The owner had already replaced the spark plugs, a coil pack, and a throttle position sensor with no luck. After hooking up our professional scan tool, we noticed erratic data from multiple sensors, but the sensors themselves tested fine. This pointed to a processing issue within the central computer. We installed a VIN-programmed PCM, and it was like a new vehicle. The stalling vanished, shifts became smooth, and the check engine light stayed off. It’s a classic case of a failing PCM creating ghost issues that can lead you down an expensive and frustrating path of replacing perfectly good parts.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication or multiple unrelated sensor failures.
- ✔ Poor Engine Performance: You may experience hesitation, stalling, rough idling, or a significant loss of power.
- ✔ Reduced Fuel Economy: A faulty PCM can’t efficiently manage the fuel-to-air ratio, causing your vehicle to consume more gasoline.
- ✔ Transmission Shifting Issues: The PCM controls transmission solenoids, so a failure can lead to hard shifting, delayed engagement, or being stuck in one gear.
- ✔ No-Start Condition: In severe cases, the PCM may fail to control the ignition or fuel systems, preventing the engine from starting at all.
- ✔ Failed Emissions Test: Improper engine management will almost certainly lead to a failed smog or emissions inspection.

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. We program the module to your vehicle’s VIN before it ships. It arrives ready for installation. In some cases, a security or CASE relearn procedure may be required, which can be done with a capable scan tool.
Where do I provide my VIN?
You can add your vehicle’s 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email to retrieve it before we can process and ship your order.
Is this a brand new part?
This is a high-quality, genuine OEM part that has been thoroughly inspected, tested, and prepared to function to original factory standards. It is loaded with the latest software from GM for your vehicle.
Will this fix my vehicle’s problem?
This module will correct issues directly caused by a failing PCM. It is crucial to properly diagnose your vehicle’s problem before ordering. If you have multiple unrelated error codes, erratic engine behavior, or a no-start condition that isn’t caused by a mechanical failure, the PCM is a very likely culprit.
What is the difference between a PCM and an ECM?
The terms are often used interchangeably. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module) controls both the engine and the transmission, which is standard on most modern vehicles like your 2006 GM model.
