Restore Peak Performance to Your GM Truck or Van
Is your trusty GM workhorse suffering from baffling electrical gremlins, poor engine performance, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the hidden culprit, leaving you stranded and second-guessing every part you’ve replaced. This professionally programmed 16250279 PCM is the direct, reliable solution to get your vehicle back on the road and running like it should, restoring both its performance and your peace of mind.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways that mimic other component failures. If you’re experiencing any of the following, this module is the definitive solution you’ve been looking for:
- Persistent Check Engine Light (CEL) with communication error codes (P0600-P0606).
- Engine stalling unexpectedly or refusing to start.
- Rough or erratic idling and poor fuel economy.
- Harsh or incorrect automatic transmission shifting.
- Apparent failure of multiple sensors at once.
- No communication with your OBD2 scan tool.
Instead of continuing to chase expensive and time-consuming diagnostic dead ends, address the core of the problem with this fully tested and programmed engine computer.

An Expert’s Insight
As a technician with over two decades of experience, I’ve seen countless hours and dollars wasted on replacing perfectly good sensors and wiring harnesses when the vehicle’s ‘brain’ was the real issue. In these late-90s GM trucks and vans, the internal circuits of the PCM can degrade over time, causing intermittent faults that are a nightmare to diagnose. Installing a quality, pre-programmed 16250279 PCM isn’t just swapping a part—it’s a definitive repair that eliminates guesswork and gets your reliable vehicle back to work.
Frequently Asked Questions
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you can reply to your order confirmation email with the 17-digit VIN. You can also add the VIN to the ‘notes’ section during checkout. We cannot ship your part until we receive the VIN.
Will I need to do anything after installing this PCM?
Yes. After installation, you will need to perform a security relearn procedure, sometimes called a CASE (Crankshaft Angle Sensor Error) relearn. This process syncs the new computer to your vehicle’s anti-theft system and crankshaft position sensor. The procedure is simple and can typically be done without any special tools. Instructions are widely available online for your specific model.
Is this a new computer?
No, this is a high-quality, used OEM computer that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped. This provides the reliability of a genuine GM part at a significant savings.
Will this programmed 16250279 PCM fix my specific problem?
If your vehicle has been correctly diagnosed with a faulty PCM, this part is the solution. It is designed to resolve issues directly caused by the engine computer. However, it will not fix problems related to other faulty mechanical or electrical components on the vehicle.
What if my original part number is slightly different?
This computer is a direct replacement for several part numbers, including 09355699, 16266645, and others listed in the compatibility chart. As long as your vehicle, year, and engine are on the fitment list, our VIN-specific programming will ensure it functions correctly.
