Restore Your GM’s Drivability and Reliability
Is your 1997 GM vehicle suffering from erratic engine behavior, poor fuel economy, or a persistent Check Engine light? A failing Powertrain Control Module (PCM) can be the source of these frustrating and complex issues. This pre-programmed engine computer is the definitive solution to restore your vehicle’s reliability and get you back on the road with confidence. Stop guessing and replace the core of your engine management system with a unit that’s ready to perform right out of the box.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing issues like sudden stalling, a no-start condition, rough or inconsistent idle, harsh transmission shifting, or inexplicable drops in fuel efficiency, the engine computer is a primary suspect. This is especially true if you have Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0605, which point directly to an internal module fault. Our Programmed 1997 GM PCM 16218070 is the direct, reliable fix for these problems. We take the guesswork out of the repair by flashing the module with the latest GM software updates using your vehicle’s specific VIN, ensuring perfect communication between your engine, transmission, and all related systems.

Expert Insight from Our Technicians
From our 20+ years of experience, we’ve seen countless owners chase expensive sensor and component replacements when the root cause was the PCM itself. Before installing your new Programmed 1997 GM PCM 16218070, we always recommend disconnecting the vehicle’s battery and carefully inspecting the main wiring harness connectors for any corrosion, moisture, or bent pins. A clean, secure connection is absolutely critical for the new module to function correctly and will save you from future diagnostic headaches.
Frequently Asked Questions
Do I need to have this computer programmed by a dealer or mechanic?
No. This is the biggest benefit of our service. We pre-program the module using the VIN you provide, so it arrives ready to install. It’s a true plug-and-play solution that saves you time and the high cost of dealership programming.
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program it correctly.
Will this fix my Check Engine Light?
If your Check Engine Light is caused by an internal failure of the original PCM (indicated by codes like P0601, P0602, P0605), then this replacement unit will resolve the issue. If the light is on for another reason, such as a faulty sensor, that issue will need to be addressed separately.
Is this a difficult part to install?
For most individuals with basic mechanical skills, this is a straightforward installation. It typically involves disconnecting the vehicle’s battery, locating the old PCM (often in the engine bay or under the dashboard), carefully unplugging the electrical connectors, removing a few mounting bolts, and then installing the new unit in the reverse order.
How does the one-year replacement warranty work?
If the module fails due to an internal defect at any time within one year from the date of purchase, we will provide a replacement unit. This coverage provides confidence in the quality and reliability of your purchase.
How can I be sure this fits my exact vehicle?
This module fits a wide range of 1997 GM models with the 3.1L, 3.4L, or 3.8L (non-supercharged) engines. Please review the detailed fitment list on this page. As long as your vehicle is on the list, this part is the correct fit, and we will program it specifically for your VIN.
