Restore Your Alero’s Reliability and Performance
Is your Oldsmobile Alero suffering from a persistent check engine light, erratic shifting, poor fuel economy, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the culprit behind these complex issues, leaving you stranded and stressed. This direct-fit, VIN-programmed PCM is the definitive, hassle-free solution to get your vehicle running smoothly and reliably again, restoring both its performance and your peace of mind.
Common Symptoms of a Failing Alero PCM & Your Solution
If you’re experiencing any of the following, a faulty engine computer may be to blame. This unit is the direct solution for these common failure points:
- Persistent Check Engine Light: Especially for internal module error codes like P0601, P0602, P0605, or communication errors.
- No-Start or Intermittent Stalling: The engine cranks but won’t start, or it stalls unexpectedly while driving.
- Poor Engine Performance: Noticeable loss of power, hesitation, or a significant drop in fuel mileage.
- Erratic Transmission Shifting: Harsh shifts, getting stuck in gear, or failure to shift properly.
- Communication Issues: Your scan tool cannot communicate with the PCM.
Instead of risking a costly and incorrect diagnosis at a repair shop, our Programmed 2001-2003 Alero PCM provides a reliable and straightforward fix, getting you back on the road quickly.

Expert Insight: The ‘Ghost in the Machine’ Fixed
We once worked with a customer whose 2002 Grand Am (which uses the same PCM) had a baffling intermittent stalling issue that two different shops couldn’t solve. They replaced the crank sensor, fuel pump, and ignition module to no avail. The issue was a hairline crack on the PCM’s internal board that would only cause a problem when the unit heated up. Installing our properly Programmed 2001-2003 Alero PCM not only fixed the stall instantly but also smoothed out the idle and improved throttle response due to the updated software. Sometimes, the ‘brain’ is the root of many frustrating electronic gremlins.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module is completely plug-and-play. We program it using the VIN you provide during checkout, so it’s ready for installation right out of the box.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
Will this fit my vehicle if my part number is different?
Yes, this module is a direct replacement for several part numbers, including 12209614, 12202600, and 09360210. As long as your vehicle is on the compatibility list, our VIN programming ensures it will work correctly.
What is a CASE Relearn and will I need one?
A Crankshaft Variation Relearn (CASE Relearn) synchronizes the new PCM with your engine’s crankshaft position sensor. While the vehicle will run without it, performing this procedure with a compatible scan tool is sometimes necessary to turn off the check engine light and ensure optimal performance. Many local repair shops can perform this service for a small fee.
How can I be sure my original PCM is faulty?
While the symptoms listed above are strong indicators, it’s always best to have a qualified technician perform a full diagnostic. This includes checking for power and ground at the module and ruling out sensor or wiring issues before ordering a replacement.
What does the Powertrain Control Module do?
The PCM is the central computer, or ‘brain,’ of your vehicle. It controls all aspects of the engine and transmission, including fuel injection, ignition timing, emissions systems, and shift points, to ensure the vehicle runs efficiently and smoothly.
