Restore Peak Performance to Your Vehicle with a Programmed Powertrain Control Module
Is your 1997-1998 Oldsmobile Achieva, 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 symptoms of a failing Powertrain Control Module (PCM), the central computer responsible for managing your engine’s performance. A faulty PCM can disrupt everything from fuel delivery and ignition timing to transmission shifting, making your vehicle unreliable and frustrating to drive. This replacement PCM, part number 16228016, is the definitive solution to restore your vehicle’s original functionality and efficiency.
Unlike generic modules that require expensive dealer programming, this unit is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. We install the latest GM-authorized software updates, ensuring all factory improvements for performance, emissions, and drivability are in place. This VIN-specific programming makes installation straightforward, eliminating compatibility issues and getting you back on the road faster.
From the Diagnostic Bay
We once had a 1998 Pontiac Grand Am with the 2.4L engine come into the shop with a maddeningly intermittent stalling problem. It would die at stoplights, but only after it was fully warmed up. The check engine light would flash random, unrelated codes for the O2 sensor and EGR valve, which both tested fine. After hours of chasing electrical gremlins and testing sensors, we focused on the PCM. On a hunch, we used a heat gun to gently warm the module with the engine running. Within a minute, the engine stumbled and died. The original PCM had an internal fault that only appeared when it reached operating temperature. We installed a VIN-programmed replacement, and the car ran perfectly. It’s a powerful reminder that when multiple, unrelated systems act up, the central computer is often the culprit.
Symptoms of a Failing GM PCM 16228016
- ✔ Persistent Check Engine Light: Often with codes related to internal module failure, memory errors, or communication faults.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the PCM fails to control ignition and fuel correctly.
- ✔ No-Start Condition: The vehicle may crank but refuse to start if the PCM is not activating the fuel pump or ignition coils.
- ✔ Poor Fuel Economy: Incorrect air/fuel ratio calculations can lead to a sudden and significant drop in gas mileage.
- ✔ Erratic Automatic Transmission Shifting: The PCM often controls shift points, and a failure can cause harsh shifts, delayed engagement, or getting stuck in one gear.
- ✔ Failure to Communicate with a Scan Tool: If your diagnostic scanner cannot connect to the vehicle’s computer, it’s a strong sign the PCM itself has failed.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you can add your 17-digit VIN to the order notes or reply to your order confirmation email. We cannot ship your part until we have this information to program it correctly for your vehicle.
Is this part difficult to install?
Installation is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, locating and unplugging the old PCM, and swapping in the new one. The most common locations are in the engine bay on the passenger side or under the dashboard on the driver’s side.
Will I need to do anything after installation?
In many cases, you may need to perform a simple security relearn procedure, also known as a Passlock or VATS relearn. This can typically be done without special tools and involves a sequence of turning the key on and off. Instructions are widely available online for your specific model.
