Common Symptoms & Your Solution
A failing PCM can cause a cascade of frustrating issues that are often misdiagnosed. If you’re experiencing any of the following, a faulty engine computer is the likely culprit:
- Persistent Check Engine Light (CEL) with communication codes (U-codes) or various sensor codes.
- Harsh or delayed transmission shifting.
- Engine stalling or stumbling, especially when warm.
- Complete no-start condition where the engine cranks but won’t fire.
- Noticeable decrease in fuel economy.
- Erratic instrument cluster behavior.

Expert Insight: Why VIN Programming is Non-Negotiable
Many sellers offer generic, unprogrammed modules, but for these 90s GM vehicles, that’s a recipe for failure. Your car’s VIN is linked to critical data: the type of transmission, gear ratios, tire size, emissions equipment, and most importantly, the anti-theft system (VATS/Pass-Key II). Our process ensures the 16227797 PCM we send you is an exact digital clone of your original, tailored to your car’s specific configuration. This crucial step prevents compatibility conflicts, no-start situations, and ensures every component works in perfect harmony, just as the factory intended.
Frequently Asked Questions
What exactly does a PCM do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission function, including fuel injection, ignition timing, emission systems, and automatic transmission shifting, to ensure optimal performance and efficiency.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your module without it. You can typically find your VIN on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Is any extra programming needed after I install it?
No, the module arrives fully programmed for engine and transmission functions. In most cases, you will simply need to perform a straightforward security relearn procedure, which can be done without any special tools and typically takes 10-30 minutes. We can provide instructions for this simple process.
How can I be sure my old PCM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Common trouble codes pointing to a bad PCM include communication errors (U-codes) or multiple, unrelated sensor codes appearing at once. This 16227797 PCM is the definitive solution for a confirmed module failure.
