Frequently Asked Questions
Do I need to program this computer myself?
Absolutely not. This 2006 GMC Envoy engine computer will arrive at your door fully programmed to the VIN you provide. The installation is a simple plug-and-play process. Just disconnect the battery, swap the modules, and reconnect the battery.
Where is the PCM located on my 2006 GMC Envoy?
On the 2006 Envoy with the 4.2L engine, the Powertrain Control Module (PCM) is typically located in the engine bay, on the driver’s side (LH side), near the firewall or inner fender.
What is a “CASE Relearn” and will I need one?
A CASE (Crankshaft Angle Sensor Error) Relearn procedure synchronizes the new PCM with your engine’s crankshaft position sensor. While the vehicle will start and run without it, performing this quick procedure with a compatible scan tool is highly recommended to ensure optimal performance and prevent a potential check engine light. Most independent repair shops can perform this for you.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will contact you with simple instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for programming.
Is this the correct part for my vehicle?
This PCM fits the 2006 GMC Envoy with the 4.2L engine, as well as many other GM models listed in the fitment guide. Please cross-reference your original module’s part number with the comprehensive list provided in our description to ensure a perfect match.
