Restore Peak Performance to Your GM Vehicle
Is your Pontiac Sunfire, Chevy Cavalier, or S10 suffering from frustrating issues like a persistent check engine light, erratic engine behavior, or a complete no-start condition? These are classic symptoms of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. Don’t let a faulty computer keep you off the road. This direct-fit PCM, part number 16245305, is the definitive solution to restore your vehicle’s reliability, efficiency, and drivability.
This isn’t just a replacement part; it’s a complete service. We program the module specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This critical step ensures that the PCM has the correct factory settings and the latest GM software updates for your specific engine, transmission, and options package. By matching the programming to your VIN, we eliminate the guesswork and the need for an expensive trip to the dealership for flashing. It’s designed to make your repair process as simple and effective as possible.
From the Diagnostic Bay
We had a 1998 Chevy S10 come into the shop with a problem that was driving the owner crazy. It would run fine for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. There were no consistent trouble codes, just a random U-code for lost communication every now and then. We checked fuel pressure, spark, and wiring, but everything seemed fine. On a hunch, we monitored the PCM’s data stream during a test drive and noticed the sensor readings would momentarily go haywire just before it stalled. The internal processor on the original PCM was failing intermittently. We installed one of these VIN-programmed modules, performed the quick crankshaft variation relearn, and the truck was back on the road, running perfectly. The customer was thrilled to have his reliable work truck back without a massive dealership bill.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) that won’t clear, often with communication-related codes (U-codes).
- ✔ Unexplained engine stalling, stumbling, or misfiring.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh, erratic, or delayed automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but will not fire up.
- ✔ Failure to pass state emissions testing due to readiness monitor issues.
- ✔ Inconsistent or non-functional gauges on the instrument cluster.

This final step syncs the new module to your vehicle’s specific sensors, ensuring smooth operation and completing the repair.
Frequently Asked Questions
Is this module ready to install right out of the box?
Yes, this PCM comes fully programmed to the VIN you provide. In many cases, you will need to perform a simple security relearn or crankshaft variation relearn procedure after installation to sync it with your vehicle’s anti-theft and sensor systems.
How do I give you my VIN?
After you complete your purchase, you will receive an email with simple instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
My original part number is 16228016. Will this part work?
Absolutely. This PCM, part number 16245305, is the correct, updated replacement for service numbers 16228016 and 8162280160. It is fully compatible.
Will this fix my transmission shifting problems?
It certainly can. The PCM controls both engine and transmission functions. If the module is the source of the problem, replacing it can resolve issues like harsh shifting, slipping, or incorrect gear selection.
Where is the PCM located on my vehicle?
On most compatible models like the Sunfire, Cavalier, and S10/Sonoma, the PCM is located in the engine bay, typically on the passenger side near the firewall or inner fender.
