Get Your Truck Running Right Again
Is your truck or van plagued by a persistent check engine light, erratic shifting, stalling, or a frustrating no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission. Don’t let a faulty module keep your reliable workhorse off the road. This replacement PCM is the definitive, hassle-free solution to restore your vehicle’s performance and dependability.
Common Symptoms & Your Solution
A failing engine computer can cause a wide range of confusing issues. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0605, or other communication errors
- Engine stalling, stumbling, or rough idling
- Harsh or unpredictable transmission shifting
- Noticeable decrease in fuel economy
- Complete no-start or intermittent starting problems
This module is the solution. We take the guesswork out of the repair by programming this unit specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures it has the correct software and calibration for your exact make, model, and engine, making installation straightforward. This is a direct replacement for part number GM PCM 16263494 and other cross-compatible numbers.

- ✔ Restored Engine Performance: With fresh software and reliable hardware, you’ll regain the smooth idle, crisp acceleration, and consistent performance you depend on.
- ✔ Plug & Drive Installation: Once you receive the module, installation is as simple as disconnecting the old unit and plugging this one in. In most cases, a simple security relearn procedure is all that’s needed to get you back on the road.
- ✔ A Cost-Effective Repair: Avoid the high costs and long wait times associated with dealership repairs. This is a practical, effective solution that gets the job done right.
- ✔ Rigorously Inspected: Every module is thoroughly inspected to ensure it meets strict quality standards, giving you confidence and peace of mind in your repair.
An Expert’s Take: The Brain of Your Operation
As a technician, I’ve seen countless work vans and trucks sidelined by a bad PCM. I remember a contractor whose Express van would stall randomly at intersections, costing him time and jeopardizing his jobs. He thought it was a fuel pump or a sensor, but the real issue was the vehicle’s brain. The PCM controls everything from fuel mixture to spark timing. Installing a properly programmed GM PCM 16263494 didn’t just fix the stalling; it made the van run smoother and more efficiently than it had in years. You’re not just replacing a part; you’re restoring the core command center of your vehicle.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact, correct software and calibrations from GM for your specific vehicle. This includes information about your engine size, transmission type, and other factory options, ensuring the PCM works perfectly right out of the box.
Is any additional programming required after installation?
No. The module arrives fully programmed to your VIN. However, you will likely need to perform a simple security relearn procedure, also known as a CASE relearn. This can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online for your specific model.
How do I know for sure if my PCM is failing?
While the symptoms listed above are strong indicators, a definitive diagnosis often requires a professional scan tool. Common fault codes pointing to internal module failure include P0601 (Internal Control Module Memory Check Sum Error) and P0606 (PCM Processor Fault). If you have these codes, the PCM is almost certainly the problem.
Will this work for other part numbers?
Yes, this module is a direct replacement for several part numbers, including 16263494, 16265035, and 8162634940. It is designed to be the correct replacement component for the extensive list of compatible vehicles shown in the fitment guide.
Is this a difficult part to replace?
For most of the compatible vehicles, the PCM is located in an accessible spot in the engine bay. The replacement process typically involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It is a very manageable job for a DIY mechanic with basic tools.
