Is Your Oldsmobile Intrigue Experiencing Mysterious Engine Problems?
The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer of your vehicle. It manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail in a vehicle like your 2000 Oldsmobile Intrigue, it can cause a wide range of frustrating and often difficult-to-diagnose issues. You might be dealing with a persistent check engine light, poor engine performance, or even a car that won’t start at all. This isn’t just an inconvenience; it’s a critical failure that can leave you stranded.
From the Diagnostic Bay
We once had a 2001 Pontiac Grand Am, which uses this exact same module, come into the shop with a bizarre set of symptoms. The owner complained of a random, harsh 1-2 transmission shift and a persistent P0302 (Cylinder 2 Misfire) code. He had already replaced the spark plugs, wires, and even the transmission shift solenoids with no success. After hooking up our diagnostic scanner and monitoring live data, we noticed the injector pulse for cylinder #2 was erratic. It wasn’t a bad injector; the command from the ECM itself was faulty. The faulty driver circuit in the ECM was also affecting signals to the transmission controller, causing the harsh shift. A single replacement 2000 Intrigue ECM, programmed to the car’s VIN, solved both problems instantly. It’s a classic example of how one failing module can create multiple, seemingly unrelated issues.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication (U-codes) or specific sensor circuits that test fine.
- ✔ Erratic Engine Performance: Your vehicle may experience stalling, rough idling, hesitation during acceleration, or a noticeable loss of power.
- ✔ Poor Fuel Economy: A failing ECM can’t properly calculate the air-fuel mixture, leading to a sudden and significant drop in MPG.
- ✔ Transmission Shifting Issues: The ECM works with the transmission control module. A faulty unit can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ No-Start Condition: The most severe symptom is when the ECM completely fails, preventing the fuel pump or ignition system from activating, meaning your engine will crank but not start.
The Direct Solution: A Programmed 2000 Intrigue ECM
This isn’t just a replacement part; it’s a comprehensive solution. We are providing a genuine GM Engine Control Module, part number 09378702, that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates flawlessly with your car’s other systems, including the anti-theft system, transmission, and instrument cluster. By programming the unit before it ships, we eliminate the need for an expensive trip to the dealership and the use of specialized scan tools. You receive a part that is ready for installation, loaded with the latest GM software updates for optimal performance and reliability.
Simple Installation and Setup
While professional installation is always recommended, replacing the ECM is a straightforward process for a knowledgeable DIYer. After disconnecting the battery, you’ll locate the module (typically in the driver’s side engine compartment on the Intrigue), disconnect the wiring harnesses, and swap the unit. After installation, you may need to perform a simple Security Relearn Procedure to sync the new ECM with your vehicle’s anti-theft system. This procedure usually involves a sequence of turning the key to the ‘ON’ position for 10-15 minutes and can be done without any special tools.

Frequently Asked Questions
What exactly does the ECM do for my car?
The ECM is the main computer that controls the engine’s functions. It takes data from sensors all over your vehicle (like oxygen sensors, crank position sensors, etc.) and uses that information to control fuel delivery, spark timing, and emissions systems to ensure the engine runs efficiently and powerfully.
Is this part ready to install when I receive it?
Yes, this ECM is shipped to you fully programmed with the latest GM software matched to your car’s VIN. In most cases, you will need to perform a simple, tool-free “Security Relearn Procedure” after installation to sync the module with your keys. Instructions for this are widely available online or in service manuals.
Where is the ECM located on a 2000 Oldsmobile Intrigue?
On the 2000 Intrigue, the ECM is typically located in the engine compartment on the driver’s side (LH side), often inside or attached to the air filter housing assembly for protection and cooling.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the part until we have the VIN to program it.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM, then this part will be the solution. However, it’s crucial to have your vehicle properly diagnosed to ensure the fault isn’t with a sensor, wiring, or another component. This module is guaranteed to be fully functional and correctly programmed.
