Ford Focus>> Management of the power unit and the fulfilled gases





Fig. 195. Control system of the power EEC-V unit: 1 — the ABS/ESP control unit (Mk20E-I); 2 — the EEC-V control unit with the built-in PATS block; 3 — the generator; 4 — the relay of turning on of the fuel pump; 5 — the fuel pump (FP); 6 — the safety relay of a power supply system (IFS); 7 — a fuel nozzle; 8 — the magnetic valve of the coal filter (EVAP); 9 — the valve of adjustment of rotation of a cranked shaft idling (IAC); 10 — the coupling of the compressor/relay of turning on of the fan, the conditioner; 11 — the electronic module of ignition, including the ignition coil; 12 — the board computer; 13 — the dashboard; 14 — the diagnostic socket; 15 — an automatic transmission only for the engine of 1,6 l of Zetec-SE; 16 — the storage battery; 17 — the ignition switch; 18 — the power supply relay; 19 — the relay of a pedal of coupling; 20 — the sensor of speed of the car; 21 — the relay of turning on of the hydraulic booster of a steering; 22 — a lambda probe (HO2S); 23 — the sensor of an angle of rotation of a camshaft; 24 — the sensor of an angle of rotation of a cranked shaft (SKR); 25 — the sensor of a detonation (KS) for Zetec-SE; 26 — the sensor of temperature of a head of the block (SNT); 27 — the sensor of provision of a butterfly valve; 28 — the sensor of a mass consumption of air (MAF) with the built-in sensor of temperature of the air intake (IAT)



The engine has electronic control of the last generation EES-V. Three-componental catalytic converter is applied to decrease in toxicity of the fulfilled gases on the car. The control unit is not served by the engine, for identification and elimination of malfunctions special knowledge and electronic measuring devices (system of diagnostics of FDS-2000) are required. At failure detection in injection system it is better to you to address on the service center Ford. But main issues of engine management to you should be known. It will help you to diagnose correctly malfunction and more precisely to formulate the demand for repair. Further Ford Zetec-SE engine management with electronic system of ignition (without the distributor), an operating procedure of cylinders 1 — 3 — 4 — 2 (fig. 195) will be considered .
