Ford Fiesta 2014 - 2019 Service Manual / Engine / Electronic Engine Controls - 1.6L EcoBoost (132kW/180PS) – Sigma / Electronic Engine Controls - Overview. Description and Operation

Overview

The EEC system provides optimum control of the engine through the enhanced capability of the PCM . The EEC system also has an OBD monitoring system with features and functions to meet federal regulations on exhaust emissions.

The EEC system has two major divisions: hardware and software. The hardware includes the PCM , sensors, switches, actuators, solenoids, and interconnecting terminals. The software in the PCM provides the strategy control for outputs (engine hardware) based on the values of the inputs to the PCM .

The PCM receives information from a variety of sensor and switch inputs. Based on the strategy and calibration stored within the PCM , the PCM generates the appropriate output. The system is designed to minimize emissions and optimize fuel economy and driveability. The software strategy controls the basic operation of the engine, provides the OBD strategy, controls the MIL , communicates to the scan tool over the DLC , allows for flash EEPROM , provides idle air and fuel trim, and controls failure mode effects management (FMEM).
