Get Your Yukon Running Right Again
Is your 2001-2002 GMC Yukon suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM) can be the hidden cause of poor performance, stalling, or a persistent check engine light. This replacement PCM is the reliable, straightforward solution to restore your truck’s original performance and get you back on the road with confidence. We take the guesswork out of the repair by programming the module specifically to your vehicle’s VIN before it ships, making installation as simple as possible.
Common Symptoms of a Failing GM PCM
If you’re experiencing any of the following, a failing engine computer could be the culprit. This module is the definitive solution for these common problems:
- No-Start or Hard-Start Conditions: The engine cranks but refuses to start, or takes an excessive amount of time to fire up.
- Poor Engine Performance: Noticeable loss of power, rough idling, hesitation during acceleration, or reduced fuel economy.
- Erratic Shifting: The transmission may shift harshly, slip between gears, or get stuck in one gear (limp mode).
- Persistent Check Engine Light: Especially for internal module codes like P0601, P0602, or P0606.
- Communication Errors: Your mechanic’s scan tool is unable to communicate with the PCM.

An Expert’s Note on Installation
While this module is programmed for your vehicle, GM vehicles of this era have a built-in anti-theft system (PassLock/VATS) that needs to sync with the new PCM. After installation, you will likely need to perform a simple Security Relearn Procedure. This process doesn’t require any special tools and typically involves a sequence of turning the key in the ignition. It’s a straightforward procedure you can do in your own driveway and is essential for allowing your engine to start.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it to you. This saves you the time, hassle, and expense of a dealership visit.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is required for the programming process.
Will I need to do anything after I install it?
Yes, you will need to perform a Security Relearn Procedure. This is a simple process that syncs the new PCM to your vehicle’s anti-theft system and can be done without any special tools. In some cases, a Crankshaft Position Sensor (CASE) relearn may be needed, which requires a capable scan tool.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your old PCM (such as code P0601), this replacement module will solve the issue. However, if the light is on due to other failing sensors or components on the vehicle, those issues will still need to be addressed separately.
Where can I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part compatible with other vehicles?
Yes, this PCM is a widely used component across many GM trucks, vans, and SUVs from 2001-2002, including the Chevy Silverado, Tahoe, Suburban, Sierra, and Express van, among others. It is a direct replacement for part numbers 12576160, 12200411, 12201281, and 52369718.
