Expert Mechanic’s Insight
As a tech with over two decades of experience, I’ve seen countless GM trucks and vans from this era. The P01/0411 PCM is a solid unit, but after 20+ years of heat cycles and vibrations, internal circuit board failures are common. Grabbing a used one from a salvage yard is a gamble; you don’t know its history, and it will still require dealer programming to work with your van’s security system. This professionally programmed 2001-2002 Express 2500 Engine Computer is the smart repair. It bypasses the dealership hassle and provides a reliable foundation for your engine’s health for years to come.
Frequently Asked Questions
How do I provide my VIN?
After completing your purchase, simply reply to your order confirmation email with your vehicle’s 17-digit VIN, or send it to us through the contact form on our website with your order number. We cannot ship your part until we receive the VIN.
Is this really a plug-and-play installation?
Yes, for most vehicles. We program the PCM to your VIN, which syncs it with the main components of your van. In some cases, a simple security relearn procedure (which takes 10-15 minutes and requires only your ignition key) may be necessary. We include clear instructions for this easy procedure.
Will I need to perform a Crankshaft Variation (CASE) relearn?
To prevent a P1336 trouble code, a CASE relearn is recommended after installation. This procedure requires a capable bi-directional scan tool and should be performed by your mechanic. The vehicle will run and drive without it, but the check engine light may be on until the procedure is completed.
Where is the PCM located on my 2001-2002 Express Van?
On the Express and Savana vans, the PCM is typically located in the engine compartment on the driver’s side, near the rear. It’s a silver metal box with multiple large electrical connectors.
Will this fix my specific problem?
This 2001-2002 Express 2500 Engine Computer is designed to fix all internal module-related faults. While it solves the vast majority of the symptoms listed above, it’s always essential to ensure your vehicle’s wiring and sensors are in good condition. Proper diagnosis is key to a successful repair.
