Is Your 1997 GM Vehicle Running Rough?
If your 1997 Buick Regal, Pontiac Grand Prix, Chevy Monte Carlo, or another GM vehicle with the 3.4L or 3.8L V6 engine is experiencing frustrating issues like stalling, erratic shifting, a persistent Check Engine Light, or a no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, a faulty PCM can create a cascade of problems that are difficult to diagnose. This module, part number 16227797, is the direct-fit, reliable solution to restore your vehicle’s performance and dependability.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the module until we receive your VIN, as the programming is a required step.
Is any additional programming required after installation?
In most cases, no further programming is needed. However, you may need to perform a simple security relearn procedure (often called a VATS relearn) which can typically be done without special tools. Instructions are widely available online or in service manuals.
What is the difference between a PCM and an ECM?
ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. For these 1997 GM vehicles, the terms are used interchangeably as this single module controls both the engine and the automatic transmission.
Do I need to send my old module back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
Will this fix my specific problem?
While this module corrects a wide range of common electronic issues, it’s essential to have your vehicle properly diagnosed. This part will resolve problems directly caused by a failing PCM, but it will not fix issues related to other faulty sensors or mechanical components.
