2006 Isuzu I-350 Powertrain Control Module 19209820 Programmed

Is Your 2006 Isuzu I-350 Running Rough or Not Starting at All?

If you’re dealing with a frustrating no-start condition, erratic transmission shifting, a persistent check engine light, or a truck that just doesn’t feel right, the problem might be deeper than a simple sensor. As the central command center for your engine and transmission, the Powertrain Control Module (PCM) is the brain of your Isuzu. When it fails, it can create a cascade of baffling and seemingly unrelated issues. In my 20+ years turning wrenches, I’ve seen hundreds of GM trucks and SUVs from this era—including the Isuzu I-350, Chevy Colorado, and Hummer H3—sidelined by a faulty PCM.

Diagnosing the Brain: How a PCM Fails

A failing PCM doesn’t always die suddenly. Often, the symptoms start small and get progressively worse. You might be scanning for codes and see a lot of U-codes (communication errors), or specific codes related to sensor reference voltage or injector circuits. These are classic signs that the internal processing of the PCM is compromised.

Here are the common symptoms I’ve diagnosed in my shop that point directly to the PCM:

• ✔ Engine cranks but refuses to start.
• ✔ Harsh or delayed shifting between gears.
• ✔ Multiple, unrelated diagnostic trouble codes (DTCs).
• ✔ Check Engine Light is always on, even after clearing codes.
• ✔ Poor fuel economy and a noticeable loss of power.
• ✔ Stalling at idle or while driving.

The PCM, located on the right-hand firewall of your I-350, is exposed to significant heat and vibration. Over time, internal solder joints can crack, and electronic components can fail, leading to the unpredictable behavior you’re experiencing.

The Simple, Reliable Solution: A VIN-Programmed PCM

Replacing the PCM used to mean a trip to the dealership for expensive parts and even more expensive programming. We’ve eliminated that step. This Powertrain Control Module is the definitive solution, arriving at your door programmed specifically for your 2006 Isuzu I-350. All you need to do is provide us with your vehicle’s VIN during checkout.
