Is Your Oldsmobile Intrigue Acting Up? It Could Be The Brains of the Operation.
If you’re dealing with a 2000 Oldsmobile Intrigue that just won’t run right, you know the frustration. Maybe it refuses to start one morning, or the transmission shifts with a hard, unnerving clunk. Perhaps the check engine light is on, but every sensor you replace doesn’t fix the problem. As a technician with over two decades of experience under the hood, I’ve seen these exact scenarios countless times on this specific GM platform. The culprit is often the one component that controls everything: the Powertrain Control Module (PCM).
A Technician’s Real-World Experience
“A customer’s Intrigue came in last week with these exact symptoms. It had a random no-start condition and threw codes for the crankshaft position sensor and a transmission solenoid. The owner had already replaced both parts with no luck. After verifying the wiring harnesses were intact, my diagnostic process led me straight to the PCM. The internal drivers responsible for processing those sensor signals had failed. We installed one of our pre-programmed modules, performed the security relearn, and the car started instantly and shifted perfectly. Itโs a classic failure mode I’ve diagnosed on dozens of these vehicles.”
Why the Original PCM Fails and What It Affects
The PCM in your Intrigue is essentially the vehicle’s central computer for the engine and transmission. Located in the left-hand side of the engine compartment, it’s constantly exposed to heat, vibration, and moisture. Over 20+ years, these environmental factors can cause internal solder joints to crack and electronic components to degrade. When this happens, the signals it sends and receives become corrupted, leading to a host of confusing and difficult-to-diagnose problems.
Common Symptoms of a Failing 09378702 PCM:
- โ No-Start or Intermittent Starting: The engine cranks but won’t fire up because the PCM isn’t commanding fuel or spark correctly.
- โ Harsh or Erratic Shifting: The PCM controls the transmission solenoids. A failing module can cause delayed engagement, slipping, or hard shifts between gears.
- โ Persistent Check Engine Light (CEL): You may see codes for various sensors (O2, crank, cam, etc.) that are actually in perfect working order. The PCM itself is the source of the false reading.
- โ Poor Fuel Economy and Performance: Incorrect fuel mixture and ignition timing calculations from a faulty PCM will rob your engine of power and efficiency.
- โ Communication Errors: A scan tool may be unable to communicate with the PCM, a definitive sign of a critical failure.
The Solution: A Pre-Programmed, Ready-to-Install Module
This isn’t just a replacement part; it’s a complete solution. This Powertrain Control Module, part number 09378702, is the correct, direct-fit component for your vehicle. The most critical service we provide is the programming. Before we ship it, we flash the module with the latest official GM software calibration specifically for your car, using the Vehicle Identification Number (VIN) you provide. This is a step that would otherwise require an expensive trip to a dealership with specialized tools.
By programming it to your VIN, we ensure it communicates seamlessly with your car’s other systems, including the anti-theft (Passlock) system and the Body Control Module (BCM). This eliminates compatibility headaches and gets you back on the road faster.
Installation and Getting Started
Installation is straightforward for a DIYer with basic tools. The PCM is typically located in a black plastic housing near the air filter box in the engine bay. After disconnecting the vehicle’s battery, you’ll unbolt the module and carefully release the large electrical connector levers. Seat the new module, reconnect the connectors, and reconnect the battery. In many cases, you may need to perform a simple security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. This can be done in your driveway without any special equipment.
