Is Your Envoy Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your 2006 GMC Envoy XL is stalling, shifting erratically, or simply won’t start, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical component that acts as the brain of your engine and transmission. Driving with a faulty PCM can lead to poor fuel economy, failed emissions tests, and even leave you stranded. This replacement unit is the simple, reliable, and cost-effective solution to get your truck running like new again.
Common Symptoms & Your Solution
A failing engine computer can cause a cascade of confusing issues. You might be experiencing one or more of the following:
- Check Engine Light: Often with communication error codes like P0601, P0605, or P0606.
- No-Start Condition: The engine cranks but refuses to start.
- Stalling or Misfiring: The engine cuts out unexpectedly while driving or idles poorly.
- Poor Performance: A noticeable loss of power, hesitation during acceleration, and decreased gas mileage.

We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN).
