Is Your 2007 Pontiac G5 Running Rough?
If you’re dealing with a persistent check engine light, erratic engine behavior, or a no-start condition in your 2007 Pontiac G5, a failing Powertrain Control Module (PCM) is a likely culprit. As the central computer of your vehicle, the PCM is responsible for managing everything from fuel mixture and ignition timing to transmission shifts and emissions controls. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This genuine OEM replacement PCM, part number 19210736 (also compatible with 12605843), is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2007 Cobalt SS (which shares its platform with the G5) come into the shop with a bizarre issue. The customer complained of intermittent power loss and a transmission that seemed to have a mind of its own, shifting hard at random times. The check engine light would come on and off, throwing codes that pointed to a dozen different sensors. We spent hours chasing ghosts, testing sensors and wiring, but everything checked out. On a hunch, we monitored the PCM’s live data stream and noticed the processor was occasionally dropping communication. We swapped in a pre-programmed PCM, and it was like a different car. All the phantom issues vanished. It’s a classic example of how a failing computer can mimic a multitude of other problems.
Symptoms of a Failing 2007 Pontiac G5 PCM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ A significant, unexplained drop in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle cranks but refuses to start.
- ✔ Communication errors when trying to use an OBD-II scan tool.
- ✔ Failure to pass state emissions testing due to readiness monitor issues.

Frequently Asked Questions
Do I need to get this PCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s 17-digit VIN during checkout, and the module will arrive ready for plug-and-play installation.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the computer that controls only the engine. PCM (Powertrain Control Module) controls both the engine and the transmission. For your 2007 Pontiac G5, this part functions as the PCM.
Is this a new part?
This is a high-quality, used OEM part that has been carefully removed from a salvaged vehicle. It has been inspected and is fully functional. This provides an affordable and reliable alternative to a costly new module.
Will this fix my car’s problem for sure?
This module will resolve any issues directly caused by a faulty PCM. However, it’s crucial that your vehicle has been properly diagnosed. This part cannot fix problems related to bad sensors, faulty wiring, or mechanical failures. We recommend a professional diagnosis to confirm the PCM is the source of your issue.
What information do you need from me?
After you complete your purchase, we will need your vehicle’s 17-digit VIN. You can typically find this on your dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
