Programmed 1998 Achieva PCM 16236757 | Powertrain Control Module

Is your 1998 Oldsmobile Achieva suffering from frustrating and unpredictable engine problems? Issues like a persistent check engine light, poor fuel economy, stalling, or erratic shifting can often be traced back to a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission operation. When it fails, the performance and reliability of your car can be severely compromised.

This is a direct-fit replacement Powertrain Control Module, specifically prepared for your vehicle. We take the guesswork and high cost out of the equation by programming the unit with the latest GM software updates using the Vehicle Identification Number (VIN) you provide. This ensures that the module communicates perfectly with your Achieva’s specific systems right out of the box, restoring its original performance and efficiency without requiring a trip to the dealership for expensive programming.

Diagnosing a Faulty 1998 Achieva PCM

A failing PCM can manifest in numerous ways, often mimicking other sensor or component failures. If you’ve replaced sensors and are still chasing the same issues, it’s time to consider the module itself. This unit is the definitive solution for restoring the core electronic functions of your vehicle’s powertrain.

Common Symptoms of a Failing PCM

• ✔ Persistent Check Engine Light (CEL) with various trouble codes.
• ✔ Unexplained drops in fuel mileage.
• ✔ Engine stalling, stumbling, or hesitating during acceleration.
• ✔ Rough or inconsistent idling.
• ✔ Harsh or delayed automatic transmission shifting.
• ✔ Failure to pass emissions testing.
• ✔ Complete no-start condition where the engine cranks but won’t fire.

This module is a reliable and cost-effective solution to these common problems. By providing us with your VIN at checkout, you receive a unit that is plug-and-play, ready to be installed to get you back on the road with confidence. It directly replaces OEM service numbers including 09356741, 16236757, 9357034, 9357440, and 9366314, ensuring broad compatibility.
