Restore Peak Performance to Your GM Vehicle
Is your Chevrolet Cavalier, S10, or Pontiac Sunfire suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission functions. When it falters, the entire vehicle’s performance and reliability are compromised. This replacement PCM, part number 16228016, is the definitive solution to restore your vehicle’s original drivability and efficiency.
Unlike a generic part from a local auto store or a questionable unit from a salvage yard, this module is a complete, ready-to-install solution. We take your vehicle’s unique Vehicle Identification Number (VIN) and program the module with the latest, most stable software updates directly from GM. This critical step ensures that the computer is perfectly matched to your vehicle’s specific configuration, including engine size, transmission type, and emissions equipment. This process corrects common factory software bugs and optimizes performance for a seamless installation.
From the Diagnostic Bay
We had a 1998 Chevy S10 come into the shop that was a real head-scratcher for the owner. He’d been chasing a random misfire and hard-start issue for months, replacing spark plugs, wires, and even the ignition coil pack with no success. His check engine light was on, but his local mechanic’s scanner couldn’t communicate with the computer. That was the key. We hooked up our professional diagnostic tool and confirmed a total loss of communication with the factory PCM. The internal processor had failed. We installed one of our pre-programmed 16228016 modules using his VIN, performed the quick security relearn, and the truck fired up instantly and idled perfectly. He was back on the road in under an hour, solving a problem that had plagued him for the better part of a year.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with communication-related trouble codes (e.g., U-codes).
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling, especially when coming to a stop or at idle.
- ✔ Rough, erratic, or surging engine idle.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Intermittent issues that seem to have no other logical cause.
The Direct-Fit Solution: Your 1997-1999 Cavalier PCM
Don’t let a faulty computer keep your reliable GM vehicle off the road. This module is the key to resolving complex electronic issues simply and effectively. The programming we perform is essential; a module without it will not allow the vehicle to start or run correctly due to the integrated vehicle anti-theft system (Passlock/VATS). By providing us with your VIN at checkout, you ensure that the unit you receive is truly plug-and-play. The 1997-1999 Cavalier PCM is a critical component, and our service guarantees it functions as the manufacturer intended, if not better, thanks to the updated software.
Simple Installation Process
Installation is straightforward for a DIY mechanic with basic tools. The module is typically located in the engine compartment on the passenger side. Always disconnect the negative battery terminal before beginning.
- Disconnect Power: Disconnect the negative terminal from your vehicle’s battery.
- Locate and Unplug: Find the PCM and carefully disconnect the electrical wiring harnesses. The connectors have locking tabs that must be released.
- Remove Old Unit: Unbolt the old module from its mounting bracket.
- Install New Unit: Mount the new, pre-programmed module in place and securely fasten it.
- Reconnect: Plug the wiring harnesses back into the new module until they click and lock. Reconnect the negative battery terminal.
- Security Relearn (If Needed): In some cases, a simple security relearn procedure may be necessary. This can typically be done without special tools by cycling the ignition key and waiting for a set period. Instructions are readily available online for your specific model.

Frequently Asked Questions
What do I need to do after I purchase?
After placing your order, you must provide us with your vehicle’s 17-digit VIN. You can add it as a note during checkout or send it to us in a message. We cannot program and ship your module without the VIN.
Is this part truly ‘plug-and-play’?
For most vehicles, yes. Because we program it to your VIN, it will manage the engine correctly right away. Some GM vehicles may require a simple security relearn procedure, which involves cycling the key in the ignition. This does not require a mechanic or special tools.
Where can I find my vehicle’s VIN?
Your VIN is located in several places: on a metal tag on the driver’s side of the dashboard visible through the windshield, on a sticker in the driver’s side door jamb, and on your vehicle’s registration and insurance documents.
Why is this better than a module from a junkyard?
A junkyard module is programmed to a different vehicle and will not work in yours due to the anti-theft system. It also carries the risk of having the same internal faults as your old one. Our modules are verified, tested, and programmed with the latest GM software for your specific car, ensuring a reliable, long-term fix.
Do I need to send my old part back?
No core charge or return is required for this part. You can keep or recycle your old module.
