Is Your 2007 GMC Canyon Acting Up? The PCM Is a Likely Culprit.
As a technician with over two decades of experience under the hood, I’ve seen my fair share of confusing electrical issues. When a 2007 GMC Canyon or Chevy Colorado comes into the shop with a laundry list of problemsโa persistent check engine light, erratic shifting, a rough idle, or even a frustrating no-start conditionโmy diagnostic process often leads me to one critical component: the Powertrain Control Module (PCM), also known as the Engine Control Module (ECM).
The Brain of Your Truck: Understanding PCM Failure
Think of the PCM as the central computer for your truck’s engine and transmission. It processes thousands of data points every second from sensors all over the vehicle to manage fuel injection, spark timing, transmission shift points, and emissions systems. Located on the right-hand (passenger side) firewall in these trucks, it’s subjected to intense heat cycles and constant vibration. Over 15+ years, this environment can cause internal components, like capacitors and processing chips, to degrade and fail. This isn’t a matter of poor design; it’s the reality of complex electronics in a harsh automotive environment.
Common Symptoms of a Failing 19210067 PCM
If you’re experiencing any of the following, a failing PCM is a strong possibility. I’ve personally traced these exact symptoms back to a faulty module on countless GMT355 platform trucks (Canyon, Colorado, H3, etc.).
- โ A steady or flashing Check Engine Light with communication-related fault codes (U-codes).
- โ The engine cranks but refuses to start.
- โ Noticeably poor fuel economy and sluggish performance.
- โ Harsh or delayed shifting from the automatic transmission.
- โ Stalling at idle or when coming to a stop.
- โ Inaccurate or non-functioning gauges on the instrument cluster.
Expert Pro Tip: Check Your Grounds First!
Before you spend a dollar on a new PCM, do yourself a favor and check the main engine and chassis ground connections. On these GM trucks, a corroded or loose ground strap can mimic the symptoms of a bad PCM, causing voltage drops and communication errors. I’ve seen customers replace modules only to find the real issue was a $5 fix. A few minutes with a wire brush and a wrench can save you a huge headache. Always confirm your grounds are clean and tight before condemning the computer.
The Direct-Fit Solution: A VIN-Programmed PCM Ready for Installation
This isn’t just a replacement part; it’s a complete solution. We are providing a genuine GM Electronic Control Module (part number 19210067 / 12602010) that is professionally programmed to your truck’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures that the module is a true plug-and-play component, tailored to your vehicle’s exact configuration.
Why VIN Programming is Non-Negotiable
Simply swapping a used PCM from another truck won’t work. The module is tied to the original vehicle’s security system (VATS/Passlock), engine size, transmission type, and other options. Our process eliminates these compatibility issues entirely.
- โ Security System Sync: We program the PCM to communicate correctly with your truck’s anti-theft system, preventing a no-start situation.
- โ Latest GM Updates: Your module arrives loaded with the most current GM factory software, which often includes fixes for drivability and performance issues that were discovered after your truck left the factory.
- โ No Dealer Visit Needed: You avoid the hassle and expense of having the vehicle towed to a dealership for programming. This module is ready to be installed right out of the box.

Simple Ordering & Installation Process
After you complete your purchase, simply provide us with your 17-digit VIN. Our technicians will handle the programming, and we’ll ship the ready-to-install module directly to you. Installation typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it from the firewall, and reversing the process with the new one. Once installed, a security relearn procedure may be required, which is a simple process that can be done without any special tools.
