Restore Peak Performance to Your GM Vehicle
If you’re dealing with frustrating engine problems in your Oldsmobile Intrigue or another compatible GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. As a technician with over two decades of experience, I’ve seen firsthand how a faulty PCM can cause a cascade of issues that seem impossible to pin down. This isn’t just a component; it’s the central computer for your engine and transmission, managing everything from fuel mixture and ignition timing to shift points. When it fails, your vehicle’s reliability and performance suffer dramatically.
This isn’t just a replacement part. This is a complete solution. We are providing a genuine GM PCM, part number 09378702, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest GM-authorized software updates, ensuring your engine operates with the most current logic for efficiency and performance. This critical step saves you a costly trip to the dealership and eliminates the need for specialized programming tools, making this a straightforward repair for both professional mechanics and dedicated DIYers.
Case Study: A Tricky Diagnosis
I remember a 2001 Chevy Impala with the 3.4L V6 that came into my shop with a maddeningly intermittent no-start condition. The owner had already replaced the battery and starter. We checked fuel pressure and spark, which were present one moment and gone the next. The scanner wasn’t showing any consistent codes, just a history of a P0601 (Internal Control Module Memory Check Sum Error). After verifying all the main power and ground circuits to the PCM were solid, we knew the internal logic of the module itself was failing. Swapping in a pre-programmed PCM like this one solved the problem instantly. The car started every time, and the owner was relieved to have his reliable daily driver back.
Common Signs of a Failing PCM
- ✔ Check Engine Light is on, often with codes like P0601, P0602, or P0606.
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling.
- ✔ A noticeable drop in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with your diagnostic scan tool.
A Straightforward Guide to Installation
Installing your pre-programmed 2000 Intrigue PCM is a manageable job that can be done with basic hand tools. Follow these steps carefully to ensure a smooth process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for any residual power to discharge.
- Locate the PCM: On most of these models, the PCM is found in the engine compartment, typically on the driver’s side, often attached to the air filter housing. On the Grand Am, it’s located inside behind the center of the dashboard.
- Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Do not force them. Inspect the connectors for any corrosion or damaged pins.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware as you will need it for the new module.
- Install the New PCM: Mount the new module securely onto the bracket and reconnect the electrical harnesses. Ensure they click firmly into place.
- Reconnect the Battery: Reattach the negative battery terminal and tighten it securely.
- Perform Security Relearn: Most GM vehicles of this era require a security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. Your vehicle should then start.

Frequently Asked Questions About the 2000 Intrigue PCM
Do I need to do any programming myself?
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. We flash the module with the latest GM software updates using the VIN you provide during checkout. It arrives ready to be installed.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is required for the programming process.
What is the security relearn procedure?
This is a simple procedure required by your vehicle’s anti-theft system to recognize the new PCM. It typically involves a sequence of key cycles and wait times. Instructions are readily available online for your specific model and are included with your purchase. It does not require any special tools.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. The module is usually easy to access in the engine bay. The most important part is performing the security relearn correctly after installation.
