Get Your Car Back on the Road, Fast.
Is your Chevrolet Cavalier, Pontiac Sunfire, or Grand Am suffering from an illuminated check engine light, erratic engine behavior, poor fuel economy, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the hidden culprit, leaving you stranded, stressed, and facing expensive diagnostic bills. This pre-programmed engine computer is the direct, reliable, and affordable solution to get your vehicle running smoothly and dependably again.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of issues that are often misdiagnosed. If you’re experiencing any of the following, this module is the definitive fix:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606
- Engine Stalling or Misfiring
- Rough or Inconsistent Idle
- Poor Fuel Mileage
- Harsh or Incorrect Transmission Shifting
- No Communication with a Diagnostic Scan Tool
This isn’t just another used part; it’s a complete solution. We professionally program this genuine GM engine computer specifically to your vehicle’s unique Vehicle Identification Number (VIN). This ensures it has the latest factory software updates and communicates perfectly with all of your car’s systems right out of the box. Our expertly programmed Cavalier PCM 16268310 is the answer to these deep-rooted electronic problems.

An Expert’s Insight: As a technician with over 20 years of experience, I’ve seen countless early 2000s GM vehicles with bizarre, hard-to-diagnose electrical gremlins. Mechanics often waste time and money chasing sensors and wiring, only to find the root cause was a failing PCM. The internal processors and capacitors on these units simply wear out over time. Replacing it with a properly programmed unit like this Cavalier PCM 16268310 isn’t just swapping a partโit’s restoring the vehicle’s central nervous system and providing a lasting, reliable repair.
Frequently Asked Questions
Do I need to do anything special after I install it?
In most cases, this is a direct plug-and-play installation. However, some vehicles may require a simple security relearn procedure (often called a ‘key relearn’) which you can typically do yourself in 10-15 minutes without any special tools. We include instructions for this common procedure to make it as easy as possible.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a new part?
No, this is a high-quality, tested, and fully functional used OEM part sourced from a salvaged vehicle. Using a genuine OEM part guarantees perfect fitment and electronic compatibility with your car, which is critical for a component as important as the PCM.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are classic signs of PCM failure, a professional diagnosis is the best way to be 100% certain. However, if your vehicle is experiencing multiple electronic issues, has a code like P0601 (Internal Control Module Memory Check Sum Error), or if other parts have been replaced without fixing the issue, the PCM is the most likely cause. This Cavalier PCM 16268310 is the most common solution for these specific models.
What part numbers does this computer replace?
This module is a direct replacement for several part numbers, including 09356249, 16268310, 9356249, and 9392873. If your original module has one of these numbers, this unit will work perfectly for your vehicle.
