Restore Peak Performance to Your Vehicle
Is your truck suffering from a persistent Check Engine Light, erratic engine behavior, or a no-start condition? The Powertrain Control Module (PCM), often called the engine’s brain, is the central command unit responsible for managing engine performance, fuel delivery, emissions, and transmission shifting. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. This replacement PCM, part number 19210067, is the definitive solution for getting your vehicle running reliably again.
This isn’t just a generic, off-the-shelf part. We flash this module with the latest official GM software updates specifically for your vehicle. By providing your Vehicle Identification Number (VIN) during checkout, you ensure that the unit arrives at your door programmed and ready for installation. This critical step eliminates the need for expensive dealership programming, saving you time and money and ensuring a seamless integration with your truck’s existing systems.
From the Diagnostic Bay
We recently had a 2007 GMC Canyon in the shop with a classic mystery issue. The owner had already replaced the crankshaft position sensor, camshaft position sensor, and a full set of spark plugs chasing an intermittent stalling problem. The truck would run fine for days, then suddenly die at a stoplight and refuse to restart for 10-15 minutes. No consistent codes were being stored, just a generic P0601 (Internal Control Module Memory Check Sum Error) that would pop up occasionally. After confirming all sensor wiring was intact, we focused on the PCM. A failing internal processor was causing it to randomly lose communication and shut down the engine. Installing a VIN-programmed PCM like this one resolved the issue immediately. The customer was thrilled to finally have a reliable truck again after weeks of chasing ghosts.
Diagnosing a Faulty 2007 Isuzu I-290 PCM
A failing PCM can mimic symptoms of many other faulty components, making it tricky to diagnose. However, if you’re experiencing several of the following issues, the PCM is a likely culprit. This module is the correct fit for a wide range of GM trucks, including the Isuzu I-290, Chevy Colorado, GMC Canyon, Hummer H3, and Trailblazer family. Always verify your part number before ordering.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light: Your check engine light is illuminated, often with communication error codes (U-codes) or internal processor fault codes (P06xx series).
- ✔ No-Start or Hard Starting: The engine cranks but refuses to start, or takes an unusually long time to fire up, either hot or cold.
- ✔ Engine Stalling: The engine stalls unexpectedly while driving or idling for no apparent reason.
- ✔ Poor Performance & Fuel Economy: You may notice a significant drop in power, hesitation during acceleration, and a noticeable decrease in miles per gallon (MPG).
- ✔ Erratic Shifting: The automatic transmission may shift harshly, at the wrong times, or seem to get stuck in one gear.
- ✔ Failed Emissions Test: Your vehicle cannot pass a smog check due to monitor readiness issues or specific trouble codes.
- ✔ Intermittent Electrical Issues: Seemingly unrelated problems with gauges or other electronic components can sometimes be traced back to a faulty PCM.
Plug-and-Play Solution
Our process is designed to be as simple as possible. Once you place your order, you provide us with your vehicle’s VIN. Our technicians then use this information to load the correct, updated software onto the module. This ensures that when it arrives, it’s ready to be installed. While the physical installation is straightforward—typically involving disconnecting the battery and swapping the module—some vehicles may require a security relearn procedure to sync the new PCM with the anti-theft system. This procedure is simple and can usually be done in your driveway without special tools.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) contains crucial information about your truck’s specific options, engine, transmission, and emissions equipment. We use the VIN to load the exact factory software and the latest updates for your vehicle, ensuring perfect compatibility and performance right out of the box.
Is this module difficult to install?
The physical installation is typically very simple. It involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old PCM, unbolting it, and then bolting the new one in its place. The most common location is on the right-hand (passenger side) firewall in the engine bay.
Will this require additional programming at a dealership?
No. Because we program the module to your VIN before shipping, you will not need to take it to a dealer or mechanic for expensive programming. However, you may need to perform a simple security relearn procedure, also known as a key-cycle relearn, which can be done yourself in about 15 minutes.
What is a security relearn procedure?
It’s a process that syncs the new PCM with your vehicle’s anti-theft system. A common method is the 10-minute relearn: turn the key to the ‘ON’ position (without starting the engine) for 10 minutes, then turn it off for 10 seconds. Repeat this cycle three times. On the fourth attempt, the vehicle should start, confirming the new module is synced.
Will this fix my check engine light?
If the check engine light and associated symptoms are being caused by a faulty PCM, then yes, this part will resolve the issue. It’s important to have properly diagnosed the problem to ensure the PCM is the root cause and not a bad sensor or wiring issue.
