Restore Peak Performance to Your 1997 Truck or Van
Is your 1997 Isuzu Hombre, Chevy S10, GMC Sonoma, or another compatible GM vehicle suffering from frustrating drivability issues? A faulty Powertrain Control Module (PCM) is often the hidden culprit behind a wide range of problems that can leave you stranded. This direct-fit PCM, part number 16229684, is the definitive solution to get your vehicle running reliably again. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s VIN with the latest GM software updates before it ships. This ensures a seamless installation and restores your engine’s original performance and efficiency.
From the Diagnostic Bay
I once had a 1997 GMC Jimmy come into the shop with a classic complaint: intermittent stalling and a persistent check engine light for an oxygen sensor circuit. The owner had already replaced both O2 sensors and the catalytic converter, spending hundreds of dollars with no fix. After hooking up the scanner, I noticed the live data from the sensors was erratic and inconsistent. Instead of chasing more parts, I went straight to the source. A quick check of the PCM connectors and wiring confirmed they were fine. We installed a VIN-programmed PCM, and the problem vanished instantly. The old module’s internal circuits were failing, sending bad signals and causing the false sensor codes. It’s a powerful reminder that the PCM is the brain of the vehicle, and when it’s not healthy, it can make other perfectly good parts seem faulty.
Is Your Vehicle Showing Signs of a Bad PCM?
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, it’s a strong indication that your PCM needs attention:
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns with various codes.
- ✔ Rough or erratic idling and stalling at stops.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or delayed transmission shifting.
- ✔ Engine hesitation or misfires under acceleration.
- ✔ Failure to pass an emissions test.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.

Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software for your specific vehicle.
Is this a plug-and-play installation?
Yes, for the most part. After physically installing the module, you will need to perform a simple security relearn procedure, also known as a CASE relearn. This can typically be done without special tools and instructions are readily available online or can be provided.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this will resolve the issue. However, it’s crucial to ensure that the codes are not being caused by other failing sensors or components. This PCM will fix issues originating from the computer itself.
What if my original part number is 8162296840?
This module is a fully compatible replacement for both 16229684 and 8162296840. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
