Is Your Savana 1500 Running Rough?
If your 2008-2009 GMC Savana 1500 is experiencing perplexing issues like stalling, erratic shifting, a persistent check engine light, or even a complete no-start condition, the problem often points to a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel mixture and ignition timing to transmission shift points. When it begins to fail, it can cause a cascade of problems that are frustrating and difficult to diagnose.
From the Diagnostic Bay
We had a local contractor bring in his ’09 Savana 1500 work van. The complaint was intermittent stalling at stoplights and a random P0606 (Internal Control Module Processor Error) code that would come and go. He’d already replaced the spark plugs, wires, and a couple of sensors with no luck. After hooking up our diagnostic tools and monitoring live data, we noticed the fuel trim values would suddenly drop out just before a stall. This pointed directly to an internal PCM fault. We installed one of our pre-programmed modules, performed the security relearn, and the van ran perfectly. He was back on the road the same day, no more lost time or money on guesswork.
Symptoms of a Failing Savana 1500 PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine misfires, stumbles, or runs rough.
- ✔ Unexplained drop in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle cranks but refuses to start.
- ✔ Intermittent stalling, especially when warm or at idle.
- ✔ Loss of communication with diagnostic scan tools.

Frequently Asked Questions
Is this PCM ready to install when I receive it?
Yes, this module comes programmed to your vehicle’s VIN. In most cases, it is a plug-and-play installation. However, you may need to perform a simple security or anti-theft relearn procedure, which can typically be done without special tools. Instructions are widely available online for this process.
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your Savana. You can find this on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Will this fix my specific problem or check engine light?
This PCM will resolve issues directly caused by a failing computer. While it corrects a wide range of common symptoms, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty sensors or mechanical components.
Do I need to take my van to the dealership after installation?
No. Our VIN programming service eliminates the need for a trip to the dealer for software flashing. The module arrives ready for your vehicle, saving you time and money.
