Controller family and catalog label
An engine control module uses software and calibration data to manage functions such as fuel delivery, ignition timing and emissions control. The association with engine control is tentative for this particular file. The complete identifier and catalog name do not establish its exact vehicle application or the specific behavior of this revision.
