Is Your GM Truck or Van Running Rough?
There’s nothing more frustrating than a vehicle you rely on acting up. If you’re dealing with a persistent check engine light, erratic engine behavior, poor fuel economy, or harsh shifting, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an annoyance; it’s a problem that affects your vehicle’s reliability and performance. This replacement PCM is the definitive solution to get your trusted GM vehicle back to running the way it should, with its performance and dependability fully restored.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, leaving you stranded or guessing at the problem. If you’re experiencing any of the following, it’s time to consider a replacement:
- Engine stalling, misfiring, or running rough
- Failure to start or intermittent starting issues
- Harsh or incorrect automatic transmission shifting
- Poor acceleration and loss of power
- Dramatically reduced fuel mileage
- A lit Check Engine Light with codes like P0601, P0602, P0604, or P0606
This programmed 16263494 PCM is the direct answer to these issues. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that when it arrives, it’s ready to install and communicate perfectly with all of your vehicle’s systems.
Features & Benefits
- โ VIN-Programmed for You: We flash the module with the latest GM-certified software using your VIN, ensuring it’s a perfect match for your truck or van’s specific options and security system.
- โ Plug-and-Play Installation: Because it arrives pre-programmed, installation is straightforward. In most cases, no complicated dealer tools are required for setup.
- โ Restored Performance: Corrects issues with fuel mixture, ignition timing, and transmission shift points, bringing back the smooth, reliable performance you depend on.
- โ Cost-Effective Solution: Avoid the high costs and scheduling delays of a dealership visit. This is a direct, affordable path to fixing the problem correctly.
- โ Clears Fault Codes: A new, properly functioning PCM will resolve the internal errors that cause persistent check engine lights related to the module itself.
An Expert’s Note on GM Security Systems: In many of the vehicles this module fits, GM’s Passlock or VATS anti-theft system is integrated directly with the PCM. Simply swapping a module from another vehicle won’t workโthe truck won’t start. That’s why our VIN programming service is essential. We ensure the security data on the module matches your vehicle, saving you from a costly and frustrating no-start situation. With our programmed 16263494 PCM, you’re not just buying a part; you’re buying a complete, hassle-free solution.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the PCM with the exact software and calibrations for your specific engine, transmission, and factory options. It’s also critical for matching the module to your vehicle’s anti-theft system, ensuring it will start and run correctly after installation.
Is this module difficult to install?
For someone with basic mechanical skills, installation is typically straightforward. It involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in reverse order. Since our unit comes pre-programmed, no special computer relearn is usually needed, though some vehicles may require a simple security relearn procedure that can be done without special tools.
Will this fix my check engine light?
If your check engine light is on due to an internal failure of the original PCM (common codes are P0601-P0606), this replacement module will solve the problem. However, if the light is on for other reasons, like a bad oxygen sensor or an EVAP leak, you will still need to diagnose and repair those separate issues.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) typically controls only the engine. A PCM (Powertrain Control Module) is more common in these GM vehicles and controls both the engine and the automatic transmission. ECU (Electronic Control Unit) is a more generic term. For this application, PCM or ECM refers to the same computer.
Is this a brand new part from GM?
This is a high-quality, inspected, and tested replacement part that has been programmed with the latest official GM software. It is a reliable and cost-effective alternative to sourcing a new module from a dealership, providing the same functionality and performance to get your vehicle back on the road.
