1997 Grand Am Engine Control Module 16218070 Programmed To Your VIN VIN ECM PCM ECU

Is Your 1997 Grand Am Giving You Headaches?

If you’re dealing with frustrating issues like stalling at stoplights, erratic engine behavior, a persistent check engine light, or a no-start condition, the problem might not be a sensor or a fuel pump. After 20+ years in the shop, I’ve seen countless drivers replace part after part, only to find the root cause was the vehicle’s brain: the Powertrain Control Module (PCM). For these 90s GM vehicles, a failing PCM is a common, yet often overlooked, diagnosis.

This replacement Powertrain Control Module, part number 16218070, is the definitive solution to restore your vehicle’s performance and reliability. It’s not just a part in a box; it’s a complete, ready-to-install fix for your 1997 Pontiac Grand Am and many other GM models from that era.

The Easiest PCM Replacement You’ll Ever Do

The biggest hurdle with PCM replacement has always been the need for expensive dealership programming. We eliminate that step entirely. Before we ship your module, our technicians will flash it with the latest GM software updates, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This ensures perfect communication between the engine, transmission, and all related systems, just as the factory intended.

Symptoms of a Failing 1997 Grand Am PCM

A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your likely solution:

• ✔ Unexplained Check Engine Light (CEL)
• ✔ Engine stalling or cutting out while driving
• ✔ Harsh or erratic automatic transmission shifting
• ✔ Complete no-start or intermittent starting issues
• ✔ Poor fuel economy and reduced engine power
• ✔ Inaccurate or failing dashboard gauges
• ✔ Communication error codes with a scan tool

Plug-and-Play Installation: No Dealer Visit Required

Getting your car back on the road is straightforward. Once you receive your VIN-programmed module, the installation is simple enough for a confident DIYer.

1. Safety First: Disconnect the negative terminal from your car’s battery.
2. Locate the PCM: On most 1997 GM models like the Grand Am, the PCM is located in the engine bay, often inside the air filter housing or mounted to the firewall.
3. Disconnect and Remove: Carefully unplug the electrical harness connectors. They have locking tabs that need to be released. Then, unbolt the old module from its mounting bracket.
4. Install the New Module: Bolt your new, pre-programmed PCM into place. Reconnect the electrical harnesses, ensuring they click securely into place.
5. Reconnect Battery: Re-attach the negative battery terminal.
6. Final Step: Turn the key to the ‘ON’ position (without starting the engine) for 15 seconds to allow the system to initialize. Then, start your vehicle. The repair is complete!
