Is Your Alero, Grand Am, Cavalier, or Sunfire Running Poorly?
If your vehicle is experiencing perplexing issues like random stalling, erratic shifting, a persistent check engine light, or a complete no-start condition, the root cause is often a failing Powertrain Control Module (PCM). This component is the central computer of your vehicle, managing everything from fuel injection and ignition timing to transmission operation and emissions. When it fails, it can create a cascade of problems that are frustrating and difficult to diagnose. This replacement PCM, part number 9392873, is the reliable, cost-effective solution to restore your vehicle’s performance and get you back on the road with confidence.
We once had a 2001 Pontiac Grand Am with the 2.4L engine come in on a tow truck. The owner was at his wit’s end. The car would start and run perfectly for 15 minutes, then suddenly stall and refuse to restart for an hour. He had replaced the crank sensor, cam sensor, and even the fuel pump, but the problem persisted. After running a full diagnostic, we noticed the 5-volt reference signal to the sensors would drop out intermittently. Instead of just a bad sensor, this pointed to the source: the PCM itself. Heat soak was causing an internal failure in the module’s voltage regulator. We installed one of these VIN-programmed PCMs, performed the security relearn, and the car ran perfectly. It’s a classic example of how a failing computer can mimic other component failures, making a direct-fit, pre-programmed module the fastest path to a correct repair.
Symptoms of a Failing Powertrain Control Module
A faulty PCM can manifest in various ways. If you’re noticing any of the following, it’s a strong indicator that your engine computer may need replacement:
- ✔ Check Engine Light: The light is on, and you may have codes related to sensor circuits (e.g., P0601, P0605), or multiple, seemingly unrelated codes.
- ✔ No-Start or Hard Starting: The engine cranks but won’t start, or takes an unusually long time to fire up, either hot or cold.
- ✔ Engine Stalling: The vehicle stalls unexpectedly while driving or idling for no apparent reason.
- ✔ Poor Engine Performance: You may experience rough idling, hesitation on acceleration, reduced power, and a significant drop in fuel economy.
- ✔ Erratic Transmission Shifting: The automatic transmission may shift harshly, at the wrong times, or get stuck in one gear (limp mode).
- ✔ Failed Emissions Test: An internal PCM fault can prevent the emissions monitors from setting, leading to an automatic failure.
Why Choose a VIN-Programmed 2000-2001 Alero PCM?
This isn’t just a generic, off-the-shelf part. We take a tested, functional PCM from a salvaged vehicle and program it specifically to your car using the Vehicle Identification Number (VIN) you provide. This critical step ensures compatibility and proper function. The programming installs the latest GM software updates and calibrates the module for your vehicle’s specific engine, transmission, and options. This means it will manage fuel delivery, spark timing, and shift points exactly as the factory intended. Bypassing this step with a non-programmed unit will almost certainly result in a no-start condition due to the vehicle’s anti-theft system.
Direct Fit and Functionality
This PCM is a direct replacement for original equipment part numbers 09356249, 16268310, and 9392873. It is guaranteed to fit the following vehicles with the specified options:
- 2000-2001 Oldsmobile Alero: Electronic Control Module; (LH center dash), 2.4L
- 2000-2001 Pontiac Grand Am: Electronic Control Module; (LH center dash), 2.4L
- 2000-2001 Chevrolet Cavalier: Electronic Control Module; (RH front engine compartment)
- 2002 Chevrolet Cavalier: Electronic Control Module; (RH front engine compartment), ID 9356249
- 2000-2001 Pontiac Sunfire: Electronic Control Module; (RH front engine compartment)
- 2002 Pontiac Sunfire: Electronic Control Module; (RH rear engine compartment), ID 9356249
After purchase, simply send us your 17-digit VIN. We will handle all the programming, so when the part arrives, you can focus on installation. Please note that on many GM vehicles of this era, a simple security relearn procedure (often called a VATS or Passlock relearn) may be required after installation. This procedure is straightforward and does not require special tools.
Frequently Asked Questions
Do I need to get this PCM programmed?
No. This PCM comes fully programmed to your vehicle’s specific VIN before we ship it. You must provide us with your 17-digit VIN at the time of purchase to ensure correct software and calibration.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It contains information about the manufacturer, model, year, and options. We use it to load the exact GM-specified software and calibrations for your car, ensuring perfect compatibility and performance.
Is this a new computer?
No, this is a high-quality, used OEM (Original Equipment Manufacturer) computer that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped.
Will I need to perform a security relearn procedure?
Yes, it is very likely. Most GM vehicles from this period require a security relearn procedure after the PCM is replaced. This syncs the new module with your car’s anti-theft system. The procedure typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. Instructions are readily available online for your specific model.
Where is the PCM located on my 2001 Alero or Grand Am?
On the 2000-2001 Oldsmobile Alero and Pontiac Grand Am, the PCM is located inside the vehicle, behind the left-hand (driver’s side) center of the dashboard, often near the radio or climate controls.
