Restore Peak Performance to Your Vehicle
Is your 1997 Buick LeSabre, or another compatible GM vehicle, suffering from frustrating issues like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). The PCM is the electronic brain of your vehicle, meticulously managing the engine and transmission functions to ensure smooth, efficient operation. When it begins to fail, it can cause a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs.
This replacement Powertrain Control Module, part number 16217058, is the definitive solution to get your car running right again. We take the guesswork and hassle out of the process. Before this unit ships, we program it specifically to your vehicle using the VIN you provide. This ensures that it has the latest GM software updates and is perfectly matched to your car’s original factory specifications. This isn’t just a replacement part; it’s a direct-fit, fully integrated solution designed to restore the reliability and performance you expect from your vehicle.
Diagnosing a Faulty 1997 LeSabre PCM
A failing PCM can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following symptoms, your module is the likely culprit. Replacing your faulty unit with our pre-programmed module can resolve these issues and get you back on the road with confidence.
- ✔ Unexplained Check Engine Light (CEL) illumination, even after clearing codes.
- ✔ Rough or inconsistent engine idling.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Harsh, delayed, or erratic automatic transmission shifting.
- ✔ Intermittent stalling or complete failure to start the engine.
- ✔ Communication errors with diagnostic scan tools.
- ✔ False sensor codes being stored in the system.
From the Diagnostic Bay
We had a 1997 Buick Regal come into the shop with a persistent transmission shifting problem. The owner had already replaced the transmission solenoids and the vehicle speed sensor based on some stored codes, but the harsh 1-2 shift remained. We connected our professional scan tool and noticed that the PCM was slow to respond and was commanding shifts at the wrong time, despite receiving correct data from the sensors. Instead of throwing more parts at it, we swapped in a known-good, correctly programmed PCM. The car immediately started shifting perfectly. It’s a classic case where the “brain” was the problem, not the components it was controlling. This highlights the importance of considering the PCM as the root cause when multiple, seemingly unrelated symptoms appear.
Plug-and-Play Solution with VIN Programming
The biggest challenge with replacing a modern vehicle computer is the complex programming required. Our service eliminates this barrier. When you purchase this module, simply provide us with your vehicle’s 17-digit VIN. Our technicians will use this information to flash the unit with the correct software and calibrations for your specific make, model, engine, and options. This ensures seamless integration with your vehicle’s existing systems. While the module is programmed for your vehicle, some models may require a simple, key-on/key-off security relearn procedure after installation, which can typically be done in your driveway without any special tools.

Frequently Asked Questions
Do I need to have this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready to be installed with the latest GM software for your car.
Is this part truly plug-and-play?
For most vehicles, yes. Once installed, you may need to perform a simple security relearn procedure, which involves a sequence of turning the key on and off. Instructions are readily available online for this process and it requires no special tools.
Where is the PCM located on my 1997 Buick LeSabre?
On the 1997 LeSabre, the Powertrain Control Module is typically located inside the vehicle’s air filter box in the engine compartment. This placement helps protect it from heat and vibration.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, the best way to confirm is through professional diagnosis. However, if you have multiple unrelated electronic issues, a persistent check engine light with communication codes, or have ruled out other components, a faulty PCM is the most likely cause.
What happens if I install this without it being programmed to my VIN?
An unprogrammed or incorrectly programmed module will not work. It can cause a no-start condition, incorrect engine and transmission operation, and will likely trigger the anti-theft system. Our mandatory VIN programming service prevents these issues.
