Is your 1998 Grand Prix or GM vehicle running rough, stalling, or showing a persistent Check Engine Light?
A failing Powertrain Control Module (PCM) is one of the most common causes of frustrating and hard-to-diagnose engine problems. It’s the central computer of your vehicle, and when it fails, it can lead to poor performance, failed emissions tests, and even a car that won’t start. This professionally programmed engine control module is the definitive, hassle-free solution to get your car back on the road and running like it should.
Common Symptoms & Your Direct Solution
If you’re experiencing any of the following issues, a faulty PCM is the likely culprit:
- Erratic or harsh transmission shifting
- Sudden stalling or difficulty starting
- Noticeable drop in fuel economy (MPG)
- Rough or unstable idling
- Check Engine Light with codes like P0601, P0605, or other internal module errors
- Failure to pass state emissions testing

Frequently Asked Questions
Do I need to get this programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready to be installed.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the correct software for your car’s specific engine, transmission, and options.
Is this a difficult part to install?
Installation is typically straightforward. The PCM is usually located in the engine bay or under the dashboard. After swapping the part, some vehicles may require a simple security relearn procedure (often called a Passlock or VATS relearn), which can be done without special tools. Instructions are widely available online for this process.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis often involves checking for specific trouble codes related to internal module failure (like P0601-P0606). If your vehicle exhibits multiple electronic issues, erratic behavior, and has these codes, the PCM is the most probable cause.
Will this fix my car’s emission test failure?
If your vehicle failed its emissions test due to a Check Engine Light caused by a faulty PCM or related sensor data, this part is very often the correct solution. A properly functioning 1998 Grand Prix PCM 09356741 is essential for managing your vehicle’s emissions systems.
