Is Your 1996 GM Vehicle Running Rough?
If you’re dealing with a frustrating check engine light, poor fuel economy, erratic shifting, or a no-start condition in your 1996 Chevrolet Corsica, Cavalier, S10, or other compatible GM model, the problem may lie with a failing Powertrain Control Module (PCM). The PCM is the electronic brain of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it begins to fail, it can cause a cascade of confusing and performance-robbing symptoms that can be difficult to diagnose.
Don’t let a faulty computer keep you off the road. This replacement PCM, part number 16231851, is the definitive solution to restore your vehicle’s original performance and reliability. Unlike generic, off-the-shelf units that require expensive dealer programming, this module is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures perfect compatibility and function right out of the box.
The Critical Role of Your 1996 Corsica Engine Computer
The PCM in your mid-90s GM vehicle is the central command center. It takes in data from dozens of sensors throughout the engine and transmission—like the oxygen sensors, throttle position sensor, and vehicle speed sensor—and uses that information to make thousands of calculations per second. These calculations control the fuel injectors, spark plugs, and transmission solenoids to provide the optimal balance of power, efficiency, and low emissions. When the internal circuits or software of the 1996 Corsica Engine Computer degrade over time, the entire system suffers.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light: The most common indicator, often with codes related to sensor circuits, module communication, or processor faults.
- ✔ Engine Stalling or Misfiring: The computer may fail to command spark or fuel correctly, leading to rough running or stalling.
- ✔ No-Start Condition: Your engine cranks but won’t start because the PCM isn’t activating the fuel pump or ignition system.
- ✔ Poor Fuel Economy: Incorrect fuel mixture calculations can cause the engine to run too rich, wasting gas.
- ✔ Harsh or Failed Shifting: The PCM controls the automatic transmission; a fault can lead to jerky shifts, or the transmission may not shift out of a certain gear.
- ✔ Failed Emissions Test: Improper engine management will almost certainly lead to a failed smog check.
A True Plug-and-Play Solution
Our process is designed to be simple and effective. When you place your order, you provide us with your vehicle’s VIN. Our technicians then use that VIN to access the latest, most stable software updates directly from GM and flash them onto the module. This ensures that your new 1996 Corsica Engine Computer has all the factory improvements and fixes that have been released since your car was new. This critical step eliminates compatibility issues and ensures your vehicle operates exactly as the manufacturer intended. The unit arrives at your door ready for installation, saving you a trip to the dealership and hundreds of dollars in programming fees.

Frequently Asked Questions
Do I need to have this computer programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install with the latest GM software for your specific vehicle.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. You can typically find it on a small plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will I need to perform any other procedures after installation?
In some cases, you may need to perform a simple security relearn procedure, often called a VATS or Passlock relearn. This can typically be done without any special tools and involves a sequence of turning the key on and off. Instructions for this are widely available online for your specific model.
Is this a direct replacement for part number 16215830?
Yes, this module is a fully compatible, direct replacement for original GM part numbers 16231851 and 16215830.
Where is the PCM located on my vehicle?
On most of these 1996 GM models, the PCM is located in the engine bay, often on the firewall or inner fender. On S10/Sonoma trucks, it is frequently found on the passenger side fender wall. Always disconnect the vehicle’s battery before attempting to remove or install the computer.
