Restore Your Oldsmobile’s Performance and Reliability
If your 2001-2002 Oldsmobile Intrigue is experiencing frustrating issues like a persistent Check Engine Light, erratic engine behavior, poor fuel economy, or even a no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM governs everything from fuel injection and ignition timing to transmission shifting. When it falters, the entire driving experience suffers. This replacement module, part number 12209614, is the definitive solution to get your vehicle running smoothly and dependably again.
Over my 20+ years in automotive diagnostics, I’ve seen firsthand how a problematic PCM can send owners and technicians down a rabbit hole of replacing perfectly good sensors and parts. A failing module can cause intermittent problems that are incredibly difficult to trace. This module eliminates the guesswork. We take the hassle out of the repair by programming it specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This ensures 100% compatibility with your Intrigue’s factory systems, saving you a costly trip to the dealership for programming.
Case Study: A Tricky Diagnosis
I recall a customer with a 2002 Grand Prix (which uses this exact same PCM) who was ready to sell the car out of frustration. It had an intermittent stalling issue that no one could solve. It would run fine for days, then suddenly die at a stoplight. No consistent trouble codes were stored, just a generic P0601 (Internal Control Module Memory Check Sum Error) that would pop up occasionally. After verifying the wiring and power/ground circuits to the PCM were solid, we swapped in a pre-programmed module. The stalling vanished instantly. The original PCM’s internal processor was failing under specific thermal conditions, a common issue for these units after two decades of service. This replacement part provided the permanent fix.
Is Your Intrigue Showing These Warning Signs?
- ✔ Persistent Check Engine Light (CEL)
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0606
- ✔ Unexplained drop in fuel mileage
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Engine stalling, stumbling, or refusing to start
- ✔ Failure to pass state emissions testing
- ✔ Communication errors with diagnostic scan tools
A Straightforward Guide to Installation
Replacing the 2001-2002 Intrigue PCM is a manageable job for a DIY enthusiast. The module is located in the left-hand (driver’s side) engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental reconnection.
- Locate the PCM: Open the hood and find the PCM on the driver’s side of the engine bay, typically mounted near the air filter housing or firewall.
- Disconnect Connectors: Carefully unplug the electrical harness connectors from the old module. These usually have a locking tab or lever that needs to be released. Avoid forcing them.
- Remove the Old Module: Unbolt the PCM from its mounting bracket. Keep the hardware, as you may need to reuse it.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and secure it with the bolts.
- Reconnect Everything: Plug the electrical connectors firmly into the new module until they click into place. Reconnect the negative battery terminal.
- Perform Security Relearn: You will likely need to perform a simple security relearn procedure (often called a Passlock or VATS relearn) which involves turning the key to ‘ON’ for 10-15 minutes, then ‘OFF’, and repeating two more times. This allows the new PCM to sync with your vehicle’s anti-theft system.

Frequently Asked Questions
Do I need to do anything after I buy this PCM?
Yes. After your purchase, you MUST send us your vehicle’s 17-digit VIN. We cannot ship your order until we have this information, as we use it to program the module with the latest GM software for your specific vehicle.
Is this part difficult to install?
For most DIYers with basic tools, this is a straightforward installation. It involves disconnecting the battery, unplugging a few connectors, and unbolting the module. The most critical step afterward is the security relearn procedure, which does not require special tools.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM with your car’s anti-theft system. Typically, you turn the ignition key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for a few seconds, and repeat this cycle three times. Your vehicle will not start until this is completed.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM also controls transmission functions like shift points and line pressure. If the module is faulty, it can cause hard shifting, delayed shifting, or slipping. A new, correctly programmed PCM often resolves these issues.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment (OEM) part that has been programmed with the latest vehicle-specific software to ensure reliable performance.
