Restore Peak Performance to Your Truck
Is your 2004, 2005, or 2006 GMC Canyon or Chevy Colorado experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your vehicle’s engine and transmission. A faulty PCM can disrupt everything from fuel injection timing to transmission shift points, leaving you with an unreliable and inefficient vehicle. Don’t let a bad computer keep you off the road. This direct-fit replacement PCM is the reliable, straightforward solution to get your truck running like new again.
Expert Pro Tip
Before replacing your PCM, always perform a thorough check of the vehicle’s battery, charging system, and all main power and ground connections to the module. A corroded ground wire or a weak battery can often mimic PCM failure symptoms. A simple voltage drop test on the main power and ground circuits at the PCM connector can save you time and confirm that the module itself is the root cause of the problem.
Symptoms of a Failing Powertrain Control Module
- ✔ Check Engine Light is illuminated with various trouble codes (DTCs).
- ✔ Engine misfires, runs rough, or stalls unexpectedly.
- ✔ Noticeable decrease in fuel efficiency (MPG).
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle fails to start, or experiences intermittent starting problems.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass state emissions testing.

Installation Process
Installation is straightforward for a DIY mechanic with basic tools. The PCM is typically located on the right-hand (passenger side) firewall in the engine bay. Simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. After reconnecting everything, you may need to perform a security relearn procedure and a Crankshaft Position Sensor (CASE) relearn, which can often be done with a capable bidirectional scan tool or by following a specific drive cycle. This ensures all systems are communicating correctly for optimal performance.
Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive flashed with the correct GM software for your truck, ready for installation.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your truck. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is any additional setup required after installation?
In many cases, you may need to perform a security relearn (anti-theft) and a Crankshaft Position Sensor (CASE) relearn. These procedures sync the new PCM with your vehicle’s systems. A qualified mechanic or a DIYer with an advanced scan tool can typically perform these relearns.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty PCM, this replacement module will solve the problem. However, it’s crucial to ensure that other components (like sensors or wiring) are not the root cause of the issue before replacing the PCM.
Does this part fit models other than the GMC Canyon?
Yes, this PCM is compatible with a wide range of GM vehicles, including the 2004-2006 Chevrolet Colorado, 2006 Hummer H3, and various 2006 Trailblazer, Envoy, and Rainier models. Please review the detailed fitment list on this page and match your original part number to confirm compatibility.
