2006 GMC Envoy Powertrain Control Module (PCM) 12569773 – Programmed to Your VIN

Struggling with a 2006 GMC Envoy that’s throwing codes or refusing to run smoothly? As a seasoned automotive repair advisor with decades in diagnostics, I’ve seen countless owners face powertrain glitches that trace back to a faulty PCM. This pre-programmed powertrain control module, part number 12569773, arrives ready for your vehicle after you share your VIN. It incorporates the latest GM updates, ensuring optimal engine management and reliability. Let’s dive into how this fixes real-world problems and gets you back on the road.

Key Features & Benefits

This PCM isn’t just a replacement—it’s tailored specifically for your 2006 GMC Envoy using your VIN for precise matching. It supports a wide range of compatible part numbers, including 12569773, 12588650, 12589311, and more up to 19209821, making it versatile for various GM models. Key perks include enhanced fuel efficiency, smoother transmission shifts, and restored engine performance. Imagine towing a trailer up a steep hill without the hesitation or stalling you might experience now— this module recalibrates everything for peak operation.

• Programmed with the newest GM software updates for better drivability.
• Direct fit for easy swap, reducing downtime.
• Addresses common DTCs like P0601 or P0300 by resetting control parameters.
• Boosts overall vehicle responsiveness, especially in demanding conditions like city traffic or highway merging.

From my experience, owners often notice immediate improvements in idle stability and reduced emissions after installation. It’s like giving your Envoy a fresh brain to handle modern driving demands.

Common Issues & How This Fixes Them

Picture this: You’re on a family road trip, and suddenly your Envoy’s check engine light flares up, accompanied by rough idling or loss of power. These symptoms often stem from a failing PCM, which controls critical functions like fuel injection and ignition timing. Common problems include internal faults leading to no-start conditions, erratic sensor readings, or even transmission limp mode.

For instance, if you’re dealing with DTC P2135 (throttle position sensor correlation) or P0120 (throttle/pedal position sensor issues), a worn PCM could be the culprit, causing acceleration lags. This programmed module resolves that by providing updated firmware that clears these codes and prevents recurrence. Another frequent headache? Intermittent stalling in wet weather—moisture can corrupt the old unit’s circuits, but this fresh PCM ensures sealed, reliable performance.

Expert tip: Before swapping, scan for codes with an OBD-II tool. If you see patterns like misfires or communication errors, this is your fix. I’ve helped dozens of Envoy owners avoid costly dealer visits by opting for a VIN-matched PCM— it restores factory specs without the hassle.

Easy Installation Guide

Installing this PCM is straightforward for most DIYers, but always disconnect the battery first to avoid shocks. Locate it on the left-hand engine side (LH engine) in your 2006 Envoy. Remove the old unit by unplugging connectors and unbolting it— typically a 10-minute job with basic tools like a socket set.

1. Provide your VIN post-purchase for programming.
2. Once received, mount the new PCM in place.
3. Reconnect wiring harnesses securely.
4. Clear any stored codes and test drive to confirm smooth operation.

Pro advice: If you’re not comfortable, a local shop can handle it in under an hour. This prevents further damage from driving with a faulty module.
