Restore Peak Performance to Your 1996 GM Vehicle
Is your 1996 Pontiac Grand Am, Chevy Cavalier, or Buick Skylark running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These frustrating issues often point to a failing Powertrain Control Module (PCM), the electronic brain of your vehicle’s engine. A faulty PCM can disrupt everything from fuel delivery and ignition timing to transmission shifting, leading to poor performance, decreased fuel economy, and even a no-start condition. This replacement PCM is the definitive solution to get your vehicle running reliably again.
This unit is a direct-fit replacement for original part numbers 16215830 and 16231851. The critical advantage of ordering from us is that we handle the programming for you. Before we ship the module, we will flash it with the latest official GM software updates, specifically matched to your vehicle using the VIN you provide. This eliminates the need for an expensive trip to the dealership for programming, saving you time, money, and hassle. You receive a component that is ready for installation right out of the box.
From the Diagnostic Bay
We had a 1996 Chevy S10 come into the shop with a complaint of intermittent stalling and a random misfire code that just wouldn’t clear. The owner had already replaced the spark plugs, wires, and even the ignition coil pack. We checked fuel pressure and sensor data, and everything looked normal… most of the time. The problem was so erratic. After hours of chasing wires, we decided to monitor the PCM’s command outputs. We discovered the injector driver for cylinder 3 was dropping out intermittently. A new, properly programmed PCM fixed the issue instantly. It’s a classic case of how a failing computer can mimic a dozen other mechanical problems, making a solid diagnosis tricky without experience.
Is Your Vehicle Showing These Symptoms?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a faulty PCM could be the culprit:
- ✔ Persistent Check Engine Light (CEL) on the dashboard
- ✔ Engine stalling or shutting off while driving
- ✔ Rough idling or misfires
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass an emissions test
Understanding Your 1996 Grand Am PCM
The 1996 Grand Am PCM is a sophisticated computer responsible for managing all aspects of engine and transmission operation. It constantly analyzes data from sensors throughout your vehicle—like the oxygen sensors, crankshaft position sensor, and throttle position sensor—to make real-time adjustments. It controls the fuel injectors, spark timing, and transmission shift points to ensure optimal power, efficiency, and low emissions. When this central component begins to fail, the entire powertrain’s harmony is disrupted. Our pre-programmed module restores this critical function, ensuring all systems operate according to precise factory specifications.
Plug-and-Play Solution
Because we program the module to your specific VIN, installation is significantly simplified. Once you receive the part, the process typically involves disconnecting the battery, removing the old PCM, installing the new one, and reconnecting the battery. For many of these 1996 GM vehicles, you may need to perform a simple security relearn procedure (often called a VATS or Passlock relearn) to sync the new computer with your vehicle’s anti-theft system. This procedure can usually be done in your driveway without any special tools. This simple process gets you back on the road quickly, restoring the smooth and reliable operation you expect from your vehicle.

Frequently Asked Questions
Do I need to get this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and we will flash the module 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.
Where is the PCM located on my 1996 vehicle?
On most of these 1996 GM models, the PCM is located in the engine bay, often on the firewall or inner fender. On some models like the Cavalier and Sunfire, it can be found under the dash on the passenger side. Always consult a repair manual for your specific model to confirm the location before beginning work.
Will I need to perform a security relearn procedure?
Yes, it is very likely. Most GM vehicles from this era require a security relearn (VATS/Passlock) to allow the engine to start after the computer is replaced. This procedure typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. Instructions are widely available online for your specific model.
Is this a new or used part?
This is a high-quality, tested, and verified replacement part that meets or exceeds original equipment performance. Each unit is inspected and programmed to ensure reliability and proper function.
