From the Technician’s Bench
As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money with modules from a salvage yard. Those units are a gambleโthey often have the wrong calibration, are not programmed to the vehicle’s options, and can cause more problems than they solve. Our process of programming this 2005-2007 Express 1500 PCM to your specific VIN is the key difference. It ensures all the systems in your vanโfrom the engine to the anti-lock brakesโcommunicate correctly, just like a brand new part from the factory. This is the right way to do the job.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific van and its options.
Is this part difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills. On most Express vans, the PCM is located in the engine compartment. The most important step is to disconnect the vehicle’s battery before swapping the module. Since our unit comes pre-programmed, no further computer work is required after installation.
What does a PCM actually do?
The Powertrain Control Module is the central computer for your vehicle. It controls the engine’s fuel injection, ignition timing, and emissions systems, as well as the transmission’s shift points. A functioning PCM is critical for performance, fuel economy, and reliability.
Will this fix my specific check engine light codes?
This 2005-2007 Express 1500 PCM will resolve any codes directly caused by a faulty internal computer processor or driver circuit. It’s important to properly diagnose your vehicle to ensure the code isn’t being caused by a bad sensor or wiring issue elsewhere.
Is any other programming required after installation?
In most cases, no. Our VIN programming covers the essential engine and transmission calibrations. On some vehicles, a security relearn procedure (often called a CASE relearn or anti-theft relearn) may be necessary, which can typically be done without special tools. Instructions are widely available online for this simple procedure.
