Restore Your Vehicle’s Performance and Reliability
Are you tired of dealing with a car that just won’t run right? A flickering check engine light, rough idling, stalling, or a complete failure to start can be incredibly frustrating. These aren’t just annoyances; they’re signs that your vehicle’s brain—the Powertrain Control Module (PCM)—may be failing. This VIN-programmed PCM is the definitive solution to get your 1997-1999 Pontiac Sunfire and other compatible GM vehicles back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of confusing issues that are often misdiagnosed. If you’re experiencing any of the following, this module is the fix you need:
- Check Engine Light (CEL) Illumination: Often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606.
- No-Start or Hard-Start Condition: The engine cranks but refuses to start, or takes an excessive amount of time to fire up.
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.
- Erratic Shifting or Transmission Problems: The PCM also controls transmission functions, so failure can lead to harsh or incorrect gear changes.
- Stalling and Rough Idle: Your engine may stall unexpectedly at stops or idle erratically.
Instead of chasing down endless sensor replacements, address the core of the problem. We program this 1997-1999 Sunfire PCM 16245305 with the latest official GM software updates, tailored specifically to your vehicle’s VIN.

Expert Insight: The Power of Proper Programming
“Over my 20 years under the hood, I’ve seen countless hours and dollars wasted on replacing perfectly good sensors because of a faulty PCM. On these late-90s GM vehicles, the factory software can develop glitches over time, leading to phantom issues like a persistent misfire code even after a full ignition system replacement. By installing a module with fresh, updated software matched to the VIN, you’re not just replacing a part; you’re giving the entire powertrain a clean slate. It’s often the one thing that finally solves those nagging, intermittent problems and makes the car drive like it’s supposed to.”
Frequently Asked Questions
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a simple security relearn procedure, also known as a VATS relearn. This procedure can be done without any special tools and typically involves a sequence of turning the key on and off. Instructions are readily available online for your specific model, and it ensures the new PCM communicates with your vehicle’s anti-theft system.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your 1997-1999 Sunfire PCM 16245305 until we receive this information. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
How can I be sure this is the right part for my car?
Please check the list of compatible vehicles in this listing. The most accurate way to confirm is to match the service number on your current computer to one of the numbers listed (16245305, 16228016, 8162280160). If you are still unsure, feel free to contact us with your VIN, and we will verify compatibility for you.
What does “plug-and-play” mean?
It means the module arrives programmed and ready to be installed without requiring a trip to a dealership or mechanic for expensive computer flashing. Once you perform the security relearn, the vehicle should start and run correctly with the new PCM.
Will this fix my failed emissions test?
If your emissions failure is due to a Check Engine Light caused by a faulty PCM or related sensor data, then yes, this part is very likely to resolve the issue. A properly functioning PCM is critical for managing the engine and emissions systems to operate within legal limits.
