An ACDelco Professional, premium aftermarket Remanufactured Engine Control Module is a high quality replacement for many vehicles on the road today. It regulates various parts of your vehicles engine by taking the inputs from sensors and additional modules and referencing that information back to other sensors, modules, and other areas of the vehicle. Remanufacturing the engine control module is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. This engine control module will provide the same performance, durability, and service life you expect from ACDelco. ? WARNING: Cancer and Reproductive Harm -
