ACDelco 88999163 GM Original Equipment Remanufactured Engine Control Module (ECM)

The ACDelco 88999163 is a GM Original Equipment Remanufactured Engine Control Module (ECM) — a GM-recommended replacement for your vehicle's original engine management computer. The ECM serves as the central processing unit of your engine, receiving input signals from sensors and supplemental modules and using that data to precisely regulate fuel delivery, ignition timing, emissions controls, and other critical engine functions.

Key Features:

• GM Original Equipment quality — designed, engineered, and tested to meet rigorous GM standards
• Remanufactured to OE specification — existing units are disassembled, worn components are replaced with new parts, and damaged or obsolete components are discarded
• End-of-line tested — every completed unit is tested to confirm it performs to ACDelco specifications before leaving the facility
• Stores diagnostic trouble codes (DTCs) — enables technicians to quickly identify and diagnose faults across engine systems
• Environmentally responsible — remanufacturing returns components to service rather than processing them as scrap
• Programming required — this module requires programming and/or special setup procedures using GM Service Information or equivalent tools prior to installation

As a GM Original Equipment part, the ACDelco 88999163 delivers the same performance, durability, and service life as the factory-installed component. A core charge may apply — return of your original unit is required to receive the core refund.
