Get Your Van Back to Work, Fast.
There’s nothing more frustrating than a work van that won’t run right. Whether it’s a no-start condition leaving you stranded, a persistent Check Engine Light, or erratic performance that makes you question its reliability, a faulty Powertrain Control Module (PCM) can bring your business to a halt. This isn’t just an inconvenience; it’s lost time and lost income. We understand that. That’s why we offer this direct-fit, professionally programmed 2003 Savana 1500 PCM 88864822, designed to get you back on the road with confidence and minimal downtime.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways, often mimicking other sensor failures and leading to frustrating, expensive diagnostic dead ends. If your Savana, Express, or other compatible GM vehicle is experiencing any of the following, a faulty PCM is a likely culprit:
- Complete No-Start Condition: The engine cranks but will not fire up.
- Erratic Shifting or Transmission Issues: Harsh shifts, getting stuck in gear, or failure to engage.
- Poor Fuel Economy: A sudden, unexplained drop in MPG.
- Check Engine Light with Communication Codes: Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U-series codes often point directly to an internal module failure.
- Stalling or Rough Idle: The engine runs poorly, stalls unexpectedly, or idles erratically.
This module is the definitive solution. We take a genuine GM-spec unit and flash it with the latest official software updates. Then, we program it using the Vehicle Identification Number (VIN) you provide, ensuring it’s a perfect match for your vehicle’s specific configuration and options. It arrives ready for a straightforward installation, eliminating the need for an expensive trip to the dealership for programming.

A Veteran Technician’s Tip: Before you install your new 2003 Savana 1500 PCM 88864822, take 10 extra minutes to clean your battery terminals and the main engine/chassis ground connections. On these GM vans and trucks, a poor ground can cause voltage issues that mimic PCM failure and can even damage a new unit. A clean, tight connection is the cheapest insurance you can buy for your vehicle’s electrical system.
Frequently Asked Questions
Do I need to send my old computer (core) back?
No, there is no core charge or requirement to return your old module. You can keep it or dispose of it as you see fit.
Is this really a plug-and-play installation?
Yes, for the vast majority of vehicles. Because we program the module to your specific VIN, it will communicate with the other modules in your vehicle correctly upon installation. Simply disconnect the battery, swap the modules, and reconnect the battery.
What is a ‘CASE learn’ or ‘crankshaft variation relearn’?
In some cases after installation, a ‘crankshaft position sensor variation relearn’ (also known as CASE learn) may be required to clear a P1336 trouble code. This is a simple procedure that can be performed with most professional-grade scan tools and ensures the most accurate ignition timing.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information.
Will this fix my specific problem?
This programmed 2003 Savana 1500 PCM 88864822 is a direct solution for failures within the module itself. While it resolves the most common electronic issues, it’s essential to ensure your vehicle’s problem has been properly diagnosed. This part will not fix issues caused by faulty wiring, sensors, or other mechanical components.
