Restore Peak Performance to Your Vehicle
Is your 1997-1998 Buick Skylark, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine’s performance. A faulty PCM can disrupt everything from fuel injection timing to transmission shifting, leading to a frustrating and unreliable driving experience. This replacement PCM, part number 16228016, is the definitive solution to restore your vehicle’s original performance and reliability.
We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store or salvage yard, this unit is meticulously prepared for your specific car. Upon purchase, you simply provide us with your vehicle’s VIN, and our technicians will flash the module with the latest, most stable software updates directly from General Motors. This ensures perfect compatibility and optimal function right out of the box, eliminating the need for an expensive trip to the dealership for programming.
We had a 1998 Grand Am with the 2.4L engine come in with a persistent P0341 code (Camshaft Position Sensor Range/Performance). The owner had already replaced the sensor twice, along with the wiring pigtail, but the check engine light kept returning after a few miles. The car would intermittently hesitate on acceleration. We hooked up our scope and saw a clean signal from the cam sensor going into the PCM connector. However, monitoring the data stream inside the computer showed the signal dropping out. This pointed directly to a fault within the PCM’s internal circuitry. Instead of continuing to replace good parts, we installed a correctly programmed PCM. The code was cleared, and after a 20-mile test drive, the car ran perfectly with no returning faults. It’s a classic case of a bad computer making good sensors look faulty.
Common Symptoms of a Failing PCM
If your vehicle’s brain is on the fritz, it can manifest in numerous ways. Keep an eye out for these common indicators that point towards a necessary PCM replacement:
- ✔ Check Engine Light: The most obvious sign. A failing PCM can set a wide range of diagnostic trouble codes (DTCs), often for sensors or systems that are actually functioning correctly.
- ✔ Engine Stalling or Misfiring: The PCM controls spark timing and fuel delivery. If it fails, it can cause the engine to run rough, misfire, or stall unexpectedly while driving or at idle.
- ✔ No-Start Condition: A completely failed PCM will not be able to energize the fuel pump, fire the ignition coils, or pulse the injectors, resulting in an engine that cranks but won’t start.
- ✔ Poor Fuel Economy: Incorrect calculations for the air-fuel mixture can cause the engine to run too rich, drastically reducing your miles per gallon.
- ✔ Erratic Transmission Shifting: The PCM works in tandem with the transmission controller. A faulty module can cause harsh shifts, delayed engagement, or getting stuck in one gear.
- ✔ Failed Emissions Test: Since the PCM manages all emissions-related components, a malfunction will almost certainly lead to a failed smog check.

Frequently Asked Questions
Do I need to get this computer programmed?
No. This is the main benefit of our service. We program the computer for you using your vehicle’s VIN before we ship it. It will arrive ready for installation, loaded with the latest GM software for your car.
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your 17-digit VIN. You can also add it as a note during the checkout process. We cannot ship your part until we receive the VIN.
What is a security relearn procedure?
This is a simple process that syncs the new PCM with your vehicle’s anti-theft system. For most GM vehicles of this era, it involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this sequence three times. This allows the components to recognize each other. No special tools are required.
Where is the PCM located on my 1997-1998 Skylark?
On the 1997-1998 Buick Skylark, the Electronic Control Module is typically located under the hood, often situated inside the air filter box assembly for protection from the elements. Always disconnect the vehicle’s battery before attempting to remove or install the module.
Is this a brand new part?
This is a high-quality, dependable replacement part that has been thoroughly inspected, tested, and validated to meet or exceed all original factory specifications. It is a reliable and cost-effective alternative to a new dealership part.
