Is Your Buick LeSabre Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a car you can’t rely on. If your 1997 Buick LeSabre is experiencing perplexing issues like stalling at red lights, erratic shifting, a persistent check engine light, or even refusing to start, the problem often points directly to a failing Powertrain Control Module (PCM). This component is the brain of your vehicle, and when it falters, it can cause a cascade of problems that disrupt your daily life. Stop guessing and replace the core component with a reliable, VIN-programmed solution that restores the smooth, dependable performance you expect.
Common Symptoms & Your Solution
A faulty engine computer can mimic a wide range of other mechanical failures, leading to costly and incorrect repairs. If you’re noticing any of the following, a failing PCM is the likely culprit:
- Poor or harsh automatic transmission shifting
- Sudden stalling or rough idling
- A significant drop in fuel economy
- The engine cranks but refuses to start
- Check Engine Light illumination with codes like P0601, P0602, or P0605

Expert Insight: The Ghost in the Machine
As a technician, I’ve seen countless owners spend hundreds, sometimes thousands, of dollars chasing problems that weren’t there. They replace transmission solenoids, fuel pumps, and sensors, only to have the same erratic behavior return. The issue was never the parts they replaced; it was the computer giving them bad commands. A failing PCM is like a ghost in the machine, creating symptoms elsewhere. Replacing the 1997 Buick LeSabre PCM first often saves you time, money, and the immense frustration of chasing the wrong problem.
Frequently Asked Questions
Is this PCM ready to install when it arrives?
Yes. This unit is fully programmed to the VIN you provide during checkout. This makes it a true plug-and-play part, ready for installation right out of the box without the need for a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the unit to function in your car.
Will this fix my check engine light?
If the check engine light is caused by an internal fault in your original PCM (such as error code P0601), this replacement unit is designed to resolve that issue. However, if the light is on due to other failing sensors or components on the vehicle, those issues will still need to be addressed separately.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate term for this part, as it controls both the engine (Engine Control Module or ECM) and the automatic transmission. ECU (Electronic Control Unit) is a more generic term.
My original part number is 16218070. Will this work?
Absolutely. This module is a direct, compatible replacement for both part numbers 16217058 and 16218070, providing the same form, fit, and function for all listed vehicles.
