1997 Regal Powertrain Control Module 16218070 | Programmed to Your VIN

Restore Your GM’s Reliability and Performance

Is your trusty 1997 Buick Regal or other GM vehicle suddenly acting up? Unexplained stalling, a persistent Check Engine Light, or erratic transmission shifts can be incredibly frustrating. As a mechanic with over two decades of experience, I’ve seen these symptoms countless times, and they often point to one critical component: a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the central computer that manages everything from fuel mixture and spark timing to transmission shift points. When it falters, your entire vehicle’s performance suffers.

This replacement Powertrain Control Module, part number 16218070, is the definitive solution to get your vehicle running smoothly again. The biggest hurdle with PCM replacement has always been the programming. We’ve eliminated that headache. Before we ship this unit, we flash it with the latest official GM software, precisely matched to your vehicle using the VIN you provide. This means you receive a module that’s ready for installation, saving you a costly and time-consuming trip to the dealership. This is the most direct path to resolving those perplexing electronic issues and restoring the dependable performance you expect from your car.

Is Your GM Showing These Telltale Signs?

A failing PCM can cause a wide range of symptoms that are often misdiagnosed. If you’re experiencing any of the following, this module is likely the solution you need:

• ✔ Persistent Check Engine Light (CEL) that won’t clear.
• ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0605.
• ✔ Harsh or erratic automatic transmission shifting.
• ✔ Engine stalling, stumbling, or rough idling for no apparent reason.
• ✔ A complete no-start condition where the engine cranks but won’t fire.
• ✔ Poor fuel economy and a noticeable loss of engine power.
• ✔ Failure to pass an emissions or smog test.

A Straightforward Guide to Installation

Installing your new PCM is a manageable job for a DIY enthusiast. While a security relearn procedure is required after installation, the physical swap is simple. Always consult a vehicle-specific repair manual if you are unsure of any step.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
2. Locate the PCM: On most of these 1997 GM models, the PCM is located inside the air filter box in the engine compartment. You will need to remove the air filter cover to access it.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it.
4. Install the New Module: Seat your new, pre-programmed PCM into the mounting bracket and secure it. Reconnect the electrical harnesses, ensuring they click firmly into place.
5. Perform Security Relearn: Reconnect the battery. You will now need to perform the GM Passlock/VATS security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. This allows the new PCM to synchronize with your vehicle’s anti-theft system.
6. Final Check: Once the relearn is complete, start the engine. It should now run smoothly with the Check Engine Light off.
