Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing issues like a sudden drop in fuel economy, engine stalling, harsh automatic transmission shifts, or diagnostic trouble codes (DTCs) like P0601, P0605, or P0606, your engine computer is likely the cause. Our professionally programmed 1998 Buick Regal PCM 09356741 serves as the central command center for your vehicle, meticulously flashed with the latest GM software updates specific to your vehicle’s VIN.

Expert Insight from a 20-Year Technician: I’ve seen countless DIY mechanics and even professional shops chase phantom sensor issues for weeks, replacing perfectly good parts. The reality is that on these late-90s GM vehicles, the PCM is the heart of the entire operation. When it fails, it sends confusing signals everywhere. Thatโs why VIN-specific programming isn’t just a convenienceโit’s the foundation of a correct and lasting repair. A generic or junkyard module can’t replicate the precise fuel trims and shift points your vehicle needs. This programmed 1998 Buick Regal PCM 09356741 ensures all systems work in harmony, just as the factory intended.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of the engine and transmission, including fuel injection, ignition timing, emissions systems, and automatic gear shifting to ensure optimal performance and efficiency.
Do I need to do any programming after I receive this module?
No. This module is pre-programmed to the VIN you provide at checkout. This makes it a plug-and-play solution for most vehicles. In some rare cases, a security or crank relearn procedure may be necessary, which can be done with a capable scan tool.
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 essential for the programming process.
Is this a brand new part?
This is a quality-inspected, genuine OEM component that has been professionally tested, cleaned, and programmed with the latest software to ensure it functions correctly and meets our high standards for reliability.
How do I know if my PCM is the problem?
Common signs include a check engine light with internal module error codes (like P0601), unexplained performance issues, multiple unrelated error codes appearing at once, or if you’ve replaced related sensors without fixing the problem. A professional diagnosis is the best way to be certain.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original PCM, this replacement unit is designed to solve that issue. After installation, you should clear all codes with a scanner. If the light returns, there may be other mechanical or sensor issues in the vehicle that need to be addressed.
