Is Your 1997 GM Vehicle Running Poorly? The PCM Might Be the Culprit.
The Powertrain Control Module, or PCM, is the central computer of your vehicle’s engine and transmission. It controls everything from fuel injection and spark timing to transmission shift points and emissions systems. When it begins to fail, it can cause a wide range of frustrating and difficult-to-diagnose problems. If your 1997 Buick Century, Pontiac Grand Prix, Chevy Lumina, or other compatible GM model is experiencing erratic behavior, a faulty PCM is a very likely cause. This replacement Powertrain Control Module, part number 16217058, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency.
Common Symptoms of a Failing 1997 GM PCM
- ✔ Check Engine Light: The check engine light is illuminated, often with codes related to internal module failure, sensor circuits, or communication errors (e.g., P0601, P0605).
- ✔ Engine Performance Issues: You may experience rough idling, stalling, engine misfires, hesitation during acceleration, or a general lack of power.
- ✔ Poor Fuel Economy: A failing PCM can’t efficiently manage the engine’s fuel delivery, leading to a noticeable drop in your miles per gallon (MPG).
- ✔ Transmission Problems: The PCM also controls the automatic transmission. Symptoms can include harsh shifting, delayed engagement, or getting stuck in one gear (limp mode).
- ✔ No-Start Condition: In severe cases, the PCM can fail completely, preventing the engine from starting at all. This can be an intermittent or permanent issue.
- ✔ Failed Emissions Test: An improperly functioning PCM will not be able to manage the emissions control systems, leading to a failed smog or emissions inspection.

Frequently Asked Questions
Is this part ready to install when I receive it?
Yes! This module is programmed to your vehicle’s specific VIN before it is shipped. It arrives ready for installation. You may need to perform a simple security relearn procedure after installation, which can be done without any special tools.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function in your vehicle.
How do I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module) controls both the engine and the transmission. ECU (Electronic Control Unit) is a more generic term for any computer in a vehicle. For this specific application, PCM is the most accurate term.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM, then yes, this replacement part will solve the issue. It is always recommended to have the codes read by a professional or with a code scanner to confirm the diagnosis before ordering.
Do I need to send my old part back?
This listing does not require a core return. You can keep or dispose of your old module as you see fit.
