Restore Peak Performance to Your Chevrolet Camaro
Is your 2012 Camaro suffering from mysterious engine problems, a persistent check engine light, or erratic behavior? The Engine Control Module (ECM), often called the engine computer, is the electronic brain of your vehicle. It meticulously manages everything from fuel injection and ignition timing to emissions control and transmission shifting. When it begins to fail, it can cause a cascade of frustrating and potentially damaging issues. This replacement Engine Control Module, part number 12642665, is the definitive solution to get your high-performance vehicle running like new again.
From the Diagnostic Bay
We had a 2012 Camaro 3.6L come into the shop with a complaint of intermittent stalling and a check engine light for a random misfire (P0300). The owner had already replaced all the spark plugs, ignition coils, and even an oxygen sensor, but the problem persisted. After hooking up our professional scan tool and monitoring live data, we noticed the fuel trim values were wildly inconsistent and injector pulse widths were erratic under load. Instead of continuing to chase sensors, we focused on the controller. A quick check of the ECM’s power and ground circuits confirmed they were solid. The culprit was an internal failure in the original ECM. After installing one of our VIN-programmed modules, the car ran perfectly. It’s a classic case where the symptoms point to multiple parts, but the root cause is the central computer itself.
Is Your Camaro’s ECM Failing? Common Symptoms
A faulty engine computer can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your ECM may need replacement:
- ✔ Persistent Check Engine Light (CEL) that won’t clear, or illuminates with multiple, seemingly unrelated codes.
- ✔ Engine stumbling, hesitating, or misfiring, especially under acceleration.
- ✔ A significant and sudden drop in fuel economy.
- ✔ The engine cranks but refuses to start (no-start condition).
- ✔ Intermittent stalling for no apparent reason, either while driving or at idle.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Cooling fans running constantly or not turning on at all.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN, and it will arrive ready to be installed.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can easily find it on the driver’s side of the dashboard (visible through the windshield), on the sticker in the driver’s side door jamb, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to ensure that the underlying problem isn’t a bad sensor or wiring issue. We always recommend a proper diagnosis before ordering.
Is any special procedure needed after I install it?
In many GM vehicles, a security relearn procedure (also known as a Passlock or anti-theft relearn) is required. This is a simple process you can do yourself that involves turning the key in a specific sequence. It typically takes about 30 minutes and does not require any special tools. We can provide instructions for this procedure.
