Restore Peak Performance to Your 2006 Envoy
Is your GMC Envoy suffering from frustrating and unpredictable engine problems? A persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy are common signs that your Powertrain Control Module (PCM) is failing. This isn’t just an annoyance; it’s the brain of your engine, and when it falters, it affects everything from performance to safety. Don’t let a faulty computer keep your reliable SUV off the road. This professionally programmed PCM is the definitive solution to get your vehicle running like new again.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways, often leading to incorrect diagnoses and wasted money on other parts. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Check Engine Light (CEL) Illumination: Often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0605, or P0606.
- No-Start or Hard-Start Conditions: The engine cranks but refuses to start, or starts only after extended cranking.
- Poor Drivability: Unexplained stalling, rough running, hesitation during acceleration, or inconsistent transmission shifting.
- Reduced Fuel Economy: A sudden and significant decrease in your vehicle’s MPG.
- Failed Emissions Test: Inability to pass state inspection due to module-related errors.

An Expert’s Note on Programming: Many people try to save a few dollars by pulling a computer from a salvage yard, only to find their truck won’t start. That’s because on these GM vehicles, the PCM is a critical part of the anti-theft system (PassLock II). A used module is locked to the original vehicle’s VIN and security key. Our service completely bypasses this issue. By programming the 2006 GMC Envoy PCM to your VIN *before* it ships, we ensure it’s ready to communicate with your specific vehicle, often only requiring a simple security relearn procedure you can do yourself in your driveway.
Frequently Asked Questions
Do I need to do any special programming myself?
No. We handle all the primary programming before we ship. The unit arrives ready to be installed. In most cases, you will only need to perform a simple security relearn procedure, which involves cycling the key and takes about 10-15 minutes. We can provide instructions for this simple process.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your 2006 GMC Envoy PCM until we receive this information, as it is essential for the programming process.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (common codes include P0601-P0606), then this replacement unit will solve the problem. However, it’s always recommended to have your vehicle properly diagnosed to ensure the PCM is the root cause before ordering.
Is this a difficult part to install?
On the 2006 Envoy, the PCM is located on the driver’s side of the engine bay and is typically held in place by a few bolts with several electrical connectors. For someone with basic mechanical skills, it’s a very straightforward installation. Always remember to disconnect the battery before beginning the replacement.
What does the one-year replacement warranty cover?
The warranty covers the electronic module itself. If the unit fails due to an internal defect within one year of the purchase date, we will provide a replacement unit. It does not cover issues caused by improper installation or other failing parts on the vehicle.
