Is your Chevrolet Uplander giving you headaches with a persistent Check Engine Light, unpredictable stalling, or a frustrating no-start condition? As a technician with over two decades of experience, I’ve seen these symptoms countless times. Often, the root cause isn’t a faulty sensor or a wiring issue, but the vehicle’s computer itself—the Engine Control Module (ECM). This isn’t just a part; it’s the brain of your engine, and when it fails, it can create a cascade of baffling problems. Don’t keep throwing money at parts that don’t fix the issue. This is the definitive solution you’ve been looking for.
We offer a reliable, ready-to-install 2006 Uplander Engine Control Module, part number 19210737. The biggest challenge with replacing an ECM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our experts will flash the module with the latest, most stable GM factory software specific to your van. This ensures perfect communication between the engine, transmission, and all other vehicle systems, restoring the performance and reliability you depend on.
Case Study: A Tricky Diagnosis
A customer brought in a 2008 Chevy Impala (which uses a similar ECM) that had been to three other shops. The complaint was intermittent stalling and a P0601 code (Internal Control Module Memory Check Sum Error). The other shops had replaced the throttle body and mass airflow sensor, but the problem persisted. I suspected the ECM from the start. A P0601 is almost always a fatal flaw within the module’s internal processor. We installed one of our pre-programmed ECMs, matched to the car’s VIN. The customer called a week later, overjoyed. The stalling was gone, the light was off, and the car drove better than it had in years. This is the power of a correct diagnosis and a quality, properly programmed part.
Is Your Vehicle Showing These Signs of ECM Failure?
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer is the likely culprit:
- ✔ Check Engine Light is on with codes like P0601, P0606, or U0100
- ✔ Engine cranks but refuses to start
- ✔ Unexplained drops in fuel economy
- ✔ Rough or erratic engine idling
- ✔ Vehicle stalls unexpectedly while driving
- ✔ Harsh or incorrect transmission shifting
- ✔ Noticeable loss of power and poor acceleration
A Straightforward Guide to Installation
Installing your new 2006 Uplander Engine Control Module is a job most DIY mechanics can handle in their own driveway. Follow these steps for a smooth installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On the 2006 Uplander, the ECM is typically found in the left (driver’s side) of the engine compartment. It’s a silver metal box with several large electrical connectors.
- Disconnect the Wiring: Carefully release the locking tabs on each wiring harness connector and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware, as you may need to reuse it.
- Install the New ECM: Mount your new, pre-programmed module in place and securely tighten the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new ECM until they click securely in place. Reconnect the negative battery terminal.
- Final Step: Some vehicles may require a security relearn procedure, which can often be done by cycling the key. Your vehicle’s service manual will have the specific, simple steps if needed.

Frequently Asked Questions
Why do you need my VIN?
Your VIN is essential for us to load the exact, correct software for your vehicle’s specific configuration (engine, transmission, and options). This ensures the 2006 Uplander Engine Control Module works perfectly right out of the box, without needing a trip to the dealer.
Is this part difficult to install?
Not at all for most people with basic tools. It’s a plug-and-play part. You simply disconnect the battery, unbolt the old unit, bolt the new one in, and reconnect the wiring harnesses. Our installation guide above provides the key steps.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by an internal failure of the ECM (common codes P0600-P0606), then yes, this part is the correct fix. It’s always best to have the codes scanned to confirm the diagnosis before ordering.
What if I order the wrong part?
We strongly recommend matching the service number from your old ECM to the numbers listed here (19210737, 12607096, etc.) or using our detailed compatibility list. Providing your VIN helps us double-check fitment before we ship, preventing errors.
Is any additional programming needed after installation?
No. This module arrives pre-programmed and ready for installation. In some cases, a simple security or anti-theft relearn procedure is required, which typically involves a few cycles of the ignition key and does not require special tools.
