Fuel injection (gasoline) car Ford Focus Turnier 1

Description of the fuel injection system design
Intake manifold injection with Zetec-SE engine: 1 - intake camshaft; 2 - nozzle; 3 - inlet channel; 4 - spark plug For a long time now, electronically controlled fuel...

General overview — EEC-V injection system control
Fuel system: sequential fuel injection (SF1) four-port injection valves Air intake system: air quantity meter (MAF sensor); works on the principle of a hot-wire air mass...

In detail — EEC-V injection system control
Control unit EEC-V-PCM (PATS integrated): electronic engine control center. The on-board computer constantly processes the current information (speed, intake manifold...

Invisible assistants – new assistants of the EEC-V injection system
The petrol engine tuning in Focus models works - with a few exceptions - in a similar way to the engines in the Fiesta. Therefore, we will limit ourselves to only new or...

Diagnostics and communication equipment of the EEC-V injection system
Connecting the diagnostic cable (DLC): it is located in left- and right-hand drive models in the lower area of the left A-pillar behind the side trim at feet 1. Access...

Visual inspection of the injection system
Periodically check the following hoses and their fittings for proper fit and fatigue cracks: 1. Vacuum hose to the absolute pressure sensor. 2. Brake booster vacuum...

Uncertainty in the operation of the on-board computer — secondary air
Leaky areas in the intake system allow uncontrolled secondary air to pass through. This disrupts the control unit computer and leads to distorted results, for example...

Checking the idle speed
The idle speed is constantly adjusted by the control unit via the idle servomotor, depending on the consumer that is switched on (e.g. headlights, air conditioning or...

Blocking of idle speed oscillations by the system
If the battery has been disconnected, give the trip computer a head start of about 8 km to program all elements with basic data. Otherwise, proceed as follows. First of...

Checking the idle servo motor
Start the engine at idle speed. Turn on as many consumers as possible. If your Focus has power steering, turn the steering wheel all the way. The idle speed should drop...

Checking injection valves
You can find a faulty injection valve by simply feeling it with your hand. The valve does not vibrate when the engine is running, unlike others. But you should do this...

Replacing the throttle cable
The connection between the gas pedal and the throttle valve in Focus diesel engines is provided by an "electric cable", the technical term is "drive-by-wire". All Focus...
