Is Your Buick Century Running Rough?
If you’re dealing with a persistent Check Engine Light, erratic engine behavior, poor fuel economy, or even a no-start condition in your 2001-2002 Buick Century or other compatible GM vehicle, a failing Powertrain Control Module (PCM) is a likely culprit. As the central computer for your engine and transmission, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems.
This replacement Powertrain Control Module, part number 09360210, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork out of the repair by programming the module specifically for your car using your Vehicle Identification Number (VIN). This ensures that all factory settings, security information, and operational parameters are perfectly matched to your vehicle’s original specifications, making for a straightforward installation process.
Your Solution for a Reliable 2001-2002 Century PCM
Don’t let a faulty computer keep you off the road. This PCM is a direct-fit replacement, designed to meet or exceed original equipment standards. Once you place your order, simply provide us with your vehicle’s VIN, and our technicians will flash the module with the latest GM-certified software updates. This not only corrects existing issues but can also improve overall performance and efficiency by incorporating the newest calibrations from the manufacturer. The module arrives at your door ready to be installed, minimizing vehicle downtime and getting you back to driving with confidence.
From the Diagnostic Bay
We had a 2002 Buick Century come in with a complaint of intermittent stalling at stoplights and a P0300 (Random Misfire) code that just wouldn’t go away. The owner had already replaced the spark plugs, wires, and ignition coils. We checked fuel pressure, scanned for vacuum leaks, and everything seemed fine. On a whim, we monitored the PCM’s live data and noticed the injector pulse width was fluctuating wildly at idle. We swapped in a known-good, programmed PCM, and the car ran perfectly. The original module had an internal driver failure that was causing the issue, a common problem on these units that often gets misdiagnosed as a mechanical fault.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling or stumbling, especially at idle
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A noticeable drop in fuel economy
- ✔ The engine cranks but refuses to start
- ✔ Communication errors with diagnostic scan tools
- ✔ Unexplained warning lights on the dashboard
Installation and Compatibility
This module is a direct replacement for part numbers 09360210, 12209614, and 12202600. While the module is programmed for your VIN, some vehicles may require a security relearn procedure after installation to sync the new PCM with your vehicle’s anti-theft system. This is a simple process that can typically be done without special tools and instructions can be readily found for your specific model. We are committed to providing a reliable and effective part for your vehicle’s complex electronic system. A properly functioning 2001-2002 Century PCM is vital for the health and longevity of your engine and transmission.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
While the module comes programmed to your VIN, some GM vehicles require a security relearn procedure (also known as a CASE relearn or Passlock relearn) to synchronize the new module with the vehicle’s anti-theft and ignition system. This procedure is straightforward and can typically be done without special tools.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add this as a note during checkout or send it to us in a follow-up message. We cannot program and ship the module without your VIN.
Is this a plug-and-play part?
Yes, because we program it to your VIN, it is designed to be a plug-and-play installation. Once the security relearn procedure (if required) is complete, your vehicle should start and run correctly with no additional programming needed.
What if my original part number is different?
This module is a direct replacement for several part numbers, including 12209614 and 12202600. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
Will this fix my transmission shifting problems?
The PCM controls both the engine and the transmission. If your shifting problems are caused by faulty electronic signals or a failing computer, this replacement module is very likely to solve the issue. However, it will not fix mechanical problems within the transmission itself.
