Restore Peak Performance to Your GM Truck or Van
Is your trusted Chevy or GMC truck acting up? Unexplained stalling, rough idling, poor fuel mileage, or a check engine light that won’t quit can be incredibly frustrating, especially when you rely on your vehicle every day. These are often signs that the brain of your vehicleโthe Powertrain Control Module (PCM)โis failing. This isn’t just an inconvenience; it’s a problem that affects reliability and performance. Get your workhorse back in top form with this direct-replacement, VIN-programmed PCM.
Common Symptoms of a Failing PCM & Your Direct Solution
A faulty engine computer can cause a wide range of confusing issues. If you’re experiencing any of the following, a failing module is the likely culprit:
- Your vehicle won’t start, or it starts and immediately stalls.

- A noticeable drop in fuel economy.
- Check Engine Light is on with codes like P0601, P0602, P0605, or P0606.

An Expert’s Note on VIN Programming
“In my 20 years of diagnostics, I’ve seen countless people buy a used computer online only to find it won’t work. Why? Because on these GM vehicles, the PCM is not a one-size-fits-all part.

We ensure the Programmed 16250279 PCM you receive is an exact digital match for your truck, making the installation as seamless as changing a battery.”
