Restore Your Vehicle’s Performance and Reliability
Is your 1996 S10, Sonoma, or other GM vehicle running rough, stalling unexpectedly, or showing a persistent check engine light?

From the Pro’s Bench: A Critical Installation Tip
Before you install your new PCM, it is absolutely critical to disconnect the vehicle’s battery. This simple but essential step resets the related electronic systems and prevents any risk of electrical shorts that could damage the new module. While it’s disconnected, take a moment to inspect the PCM’s electrical connectors for any corrosion, moisture, or bent pins. A clean, solid connection is the foundation of a successful, long-lasting repair. Getting these small details right is what separates a quick fix from a permanent solution for your 1996 S10 PCM 16231851.
Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. The main benefit of our service is that we professionally program the module to your vehicle’s specific VIN before we ship it. It arrives ready to be installed, saving you from a costly and time-consuming trip to the dealership.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to load the exact correct software and calibrations for your truck or car.
Is this a simple plug-and-play installation?
Yes, for most vehicles, it is a straightforward swap. You disconnect the battery, remove the old module, install the new one, and reconnect the battery. Some GM vehicles of this era may require a simple security relearn procedure (often called a Passlock relearn), which can typically be done yourself in about 30 minutes without any special tools.
Will this fix my specific check engine light codes?
This PCM is the correct solution for internal module fault codes, such as P0601 (Internal Control Module Memory Check Sum Error) or P0605. If you have codes related to specific sensors (like an oxygen sensor or MAP sensor), you should diagnose those components first to ensure they are not the source of the problem.
Which vehicles does this part fit?
This module fits a wide range of 1996 General Motors vehicles, including the Chevy S10/GMC Sonoma (2.2L), Chevy Cavalier, Pontiac Sunfire, Buick Century, Oldsmobile Achieva, and more. Please refer to the detailed fitment list on this page to confirm compatibility with your specific model and engine.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty.
