ACDelco GM Original Equipment Remanufactured Engine Control Modules are GM-recommended replacements for your vehicle's original components. They regulate various parts of your vehicle's engine by receiving input from sensors and additional modules and referencing that information back to other sensors, modules, and 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 completed units are tested to help ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. These engine control modules will provide the same performance, durability, and service life you expect from ACDelco.
