Is Your GM Vehicle Acting Up? It Could Be The Powertrain Control Module.
If you’re experiencing frustrating issues like a persistent check engine light, erratic engine behavior, poor fuel economy, or even a no-start condition in your 1999 Oldsmobile Intrigue or other compatible GM vehicle, the Powertrain Control Module (PCM) is a primary suspect. As the central computer for your engine and transmission, a failing PCM can create a cascade of problems that are often difficult to diagnose. This unit, part number 09361735, is a direct-fit, used replacement that restores the critical communication and control functions your vehicle needs to run properly.
We had a 1999 Pontiac Grand Prix come into the shop with a complaint of harsh, erratic shifting and a flashing check engine light. The customer had already replaced the transmission fluid and a couple of solenoids with no improvement. Our initial scans showed multiple transmission-related trouble codes, but also a U-code for lost communication with the PCM. Instead of diving into the transmission, we checked the PCM’s power and ground circuits, which were solid. We then monitored the data stream and saw erratic sensor readings that didn’t make sense. On a hunch, we connected a known-good PCM, and instantly, the shifting smoothed out and the communication codes vanished. The original PCM had internal faults that were mimicking a major transmission failure, saving the customer thousands in unnecessary repairs. This highlights how a faulty module can send you chasing ghosts all over the vehicle.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light is illuminated with various, often inconsistent, trouble codes.
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass state emissions testing.
The Solution: A VIN-Programmed 1999 Intrigue PCM
Don’t let a faulty computer keep you off the road. This replacement PCM is the reliable and cost-effective solution to get your vehicle running right again. Unlike a generic module from a parts store, this unit is specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN) before it ships. This critical step ensures that all factory settings, including engine parameters, transmission strategy, and anti-theft systems, are correctly configured for your exact make and model. We flash the module with the latest software updates available from GM, which can often resolve underlying drivability issues that were present even before the original module failed.
This is a genuine, used OEM part sourced from a salvaged vehicle. Each unit is carefully inspected and tested to ensure functionality. By choosing a used OEM part, you are getting the same quality and durability that your vehicle was built with, without the high cost of a new module from the dealer.
Simple, Hassle-Free Process
- ✔ Place Your Order: Add this item to your cart and complete the checkout process.
- ✔ Provide Your VIN: After your purchase, reply to your order confirmation email with your vehicle’s 17-digit VIN. This is essential for programming.
Please Note: In many cases, after installation, you may need to perform a security relearn procedure (often called VATS or Passlock) and a Crankshaft Position Sensor (CASE) relearn. These are standard procedures that can be performed with a capable scan tool or by following specific instructions for your vehicle.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming flashes the module with the specific software and calibrations for your vehicle’s engine, transmission, and options. Without it, the car may not start, run poorly, or have warning lights on. We handle this for you before shipping.
Is this a plug-and-play part?
Mostly, yes. Because we program it to your VIN, it’s ready to be installed. However, some GM vehicles require a security relearn procedure and/or a CASE relearn after installation. These can often be done without a mechanic.
How do I find my original part number?
Your original PCM will have a sticker on it with the part number. For most vehicles on the fitment list, it is located in the engine compartment, often inside the air filter box housing. The number should be 09361735.
This part is listed as ‘used’. Is it reliable?
Yes. This is a genuine OEM part sourced from a salvaged vehicle. Each unit is inspected and electronically tested for full functionality before being programmed and shipped. It’s a reliable alternative to a costly new part.
What if I order the wrong part?
We strongly encourage you to match the part number (9361735) from your old module before ordering. Providing your VIN for programming is our final check. If you have any doubts, please contact us before purchasing so we can help you verify fitment.
