Is Your Isuzu Hombre or GM Vehicle Running Rough?
If you’re dealing with frustrating issues like a persistent check engine light, stalling, rough idling, or a no-start condition in your 1996-2000 Isuzu Hombre, Chevy S10, Pontiac Grand Am, or other compatible GM vehicle, the root cause is often a failing Powertrain Control Module (PCM). The PCM is the brain of your vehicle, controlling critical engine and transmission functions. When it starts to fail, it can create a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary parts.
This replacement PCM, part number 16245305, is the definitive solution to restore your vehicle’s performance and reliability. It’s not just a part; it’s a complete, ready-to-install fix. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures all factory settings, engine parameters, and transmission shift points are perfectly matched, just like the original unit. It arrives loaded with the latest available software updates from GM, which can resolve common drivability issues and improve overall efficiency.
From the Diagnostic Bay
We once had a 1999 Chevy S10 with the 2.2L engine in the shop that was driving its owner crazy. The truck would randomly stall at traffic lights and had a check engine light that no one could solve. The owner had already replaced the ignition coil, spark plugs, and even the fuel pump based on advice from various forums. When we hooked up our professional scan tool, we noticed intermittent communication loss with the PCM. Instead of throwing more parts at it, we tested the circuits and confirmed the PCM itself was failing internally. After installing a VIN-programmed module like this one, the truck ran perfectly. It’s a classic case where addressing the core problem—the failing computer—saved the customer from further headaches and expenses.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Unexplained engine stalling or cutting out while driving.
- ✔ Rough or erratic idling and poor engine performance.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Failure to pass state emissions inspections.
- ✔ Diagnostic trouble codes related to PCM communication errors (U-codes).
Why Choose a VIN-Programmed 1996-2000 Isuzu Hombre PCM?
Getting a generic, unprogrammed module from a parts store or salvage yard is a recipe for failure. Modern vehicles require the PCM to be coded to the specific VIN to function with the security system, gauges, and other onboard modules. Our process eliminates this complex step for you. Simply provide your VIN during checkout, and our technicians will flash the unit with the correct software for your exact make, model, year, and engine. This makes the installation process as close to ‘plug-and-play’ as possible, getting you back on the road faster.
This module is a direct replacement for service numbers 16228016, 8162280160, and 16245305 and fits a wide range of GM vehicles from the late 90s, including:
- 1996-2000 Isuzu Hombre (2.2L)
- 1997-2000 Chevrolet S10 / GMC Sonoma (2.2L)
- 1997-1999 Chevrolet Cavalier / Pontiac Sunfire
- 1997-1999 Pontiac Grand Am (2.4L)
- 1997-1999 Chevrolet Malibu (2.4L)

Don’t let a faulty computer keep your reliable truck or car off the road. This is the most effective and reliable way to solve complex electronic issues and restore your vehicle to its original factory operation.
Frequently Asked Questions
Do I need to program this PCM?
No. We handle all the programming for you before shipment. You must provide your vehicle’s 17-digit VIN when you place your order so we can load the correct, vehicle-specific software and the latest GM updates. It will arrive ready for installation.
Where is the PCM located on my vehicle?
The location varies by model. On trucks like the Isuzu Hombre and Chevy S10, it’s typically found in the engine compartment on the passenger side. On cars like the Cavalier, Sunfire, and Grand Am, it’s often located behind the passenger side kick panel or under the dash.
What does ‘VIN programming’ mean?
VIN programming, or ‘flashing’, is the process of loading the specific software file from the manufacturer that corresponds to your vehicle’s Vehicle Identification Number (VIN). This software controls everything from fuel injection and ignition timing to transmission shifting and anti-theft systems, ensuring all components work together correctly.
Will this fix my check engine light?
If the PCM is the confirmed cause of the check engine light and the related diagnostic codes, then yes, this part will resolve the issue. However, a check engine light can be triggered by many other faulty components. It is always best to have a proper diagnosis performed to ensure you are replacing the correct part.
Is any additional setup required after installation?
In many cases, after installing the new PCM, you may need to perform a security relearn procedure to sync the new module with your vehicle’s anti-theft system. This is typically a simple process that involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Specific instructions can be easily found for your vehicle model.
