Restore Your Vehicle’s Core Functionality
Dealing with erratic engine behavior, a persistent check engine light, or a no-start condition in your vehicle can be incredibly frustrating. These are often hallmark signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your engine’s performance, fuel economy, and emissions. This replacement PCM, part number 16245305, is the definitive solution to get your 1997-1998 Buick Skylark, or other compatible GM model, running reliably again.
The PCM acts as the brain of your vehicle, processing data from dozens of sensors to make real-time adjustments to the fuel mixture, ignition timing, transmission shifts, and more. When it fails, the entire system can be compromised, leading to a cascade of problems that can be difficult to diagnose. Simply swapping a used module from another vehicle won’t work due to the sophisticated anti-theft systems and vehicle-specific calibrations. Our solution eliminates the guesswork and the need for expensive dealership programming.
From the Diagnostic Bay
We had a 1998 Chevy S10 with the 2.2L engine come into the shop on a tow truck. The owner had spent hundreds of dollars replacing the crank sensor, ignition module, and even the fuel pump, but it still wouldn’t start consistently. It had spark and fuel pressure, but the injector pulse was intermittent. After hours of chasing wires, we connected our scan tool and found we couldn’t communicate with the factory PCM. We installed one of our VIN-programmed modules, performed the 10-minute security relearn, and the truck fired up on the first try. The original PCM had an internal failure that was mimicking other component issues, a common and costly misdiagnosis we help drivers avoid.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light is on with various communication or sensor-related fault codes (e.g., U-codes, P0601-P0606).
- ✔ Engine cranks but refuses to start.
- ✔ Poor fuel economy and noticeable loss of power.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Intermittent stalling or stumbling while driving.
- ✔ Inability for a diagnostic scan tool to communicate with the module.
- ✔ Apparent failure of multiple unrelated sensors at the same time.
The Critical Advantage of a VIN-Programmed 1997-1998 Skylark PCM
What sets this module apart is our professional programming service. Before we ship your part, we flash it with the latest official GM software updates using the Vehicle Identification Number (VIN) you provide. This process ensures the PCM is a perfect match for your vehicle’s specific configuration, including its engine, transmission, tire size, and factory options. This plug-and-play approach significantly simplifies installation, often eliminating the need for a trip to the dealership and the use of their proprietary, high-cost diagnostic tools.
Installation and Setup
Once you receive your pre-programmed module, the physical installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it from its bracket, and installing the new one in its place. After installation, you will likely need to perform a simple security relearn procedure, often called the “GM Passlock Relearn” or “Anti-Theft Relearn.” This procedure can be done without any special tools and usually involves a sequence of turning the key in the ignition. We provide clear instructions to guide you through this final step, synchronizing the new PCM with your vehicle’s anti-theft system.
This module is a direct replacement for service numbers 16245305, 16228016, and 8162280160, and fits a wide array of GM vehicles from the late 1990s and early 2000s. While this listing focuses on the 1997-1998 Skylark PCM, please verify your vehicle in the comprehensive fitment list to ensure compatibility. By providing your VIN, you guarantee that the software loaded onto the module is precisely what your vehicle needs to operate as it did from the factory.
Frequently Asked Questions
Do I need to send my old PCM (core) back?
No core charge or return is required for this part. You can keep your old module or dispose of it responsibly.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information.
Is any additional programming required after installation?
No dealership programming is needed. The module arrives ready for installation. However, you will need to perform a simple security relearn procedure, which takes about 10-30 minutes and requires only your vehicle’s key. Instructions are included.
What if my original part number is different?
This module replaces several service numbers, including 16228016 and 8162280160. As long as your vehicle’s year, make, model, and engine are on our compatibility list, this part will function correctly once programmed to your VIN.
Will this fix my specific problem?
This PCM will resolve issues directly caused by a faulty control module. While the symptoms listed are common indicators of PCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the PCM is the point of failure before ordering.
