EEC stands for Electronic Engine Control. Ford uses the computer to electronically control vehicle functions. Fuel injection computers are part of a broader title called Programmable Fuel Management Systems, whose main function is to supply a mixture of fuel and air to the engine that can be easily ignited by spark to produce reliable efficient…

The EEC thinks in a flow-log which can often be difficult for an average person to understand. So it has to be converted into text and broken up into strategies. A strategy is the arranging and planning of actions with reference to accomplishing a short-range objective. By coming up with several different strategies one can…
Requirements Saw Die grinder or Dremmel. Grinding bits. Sandpaper from 200 to 600 grit. T20 size Torx bit. Most Ford MAF (mass air flow) sensors with an aluminum housing have a post that restricts air flow inside it, such as the SN95. By removing it the vehicle can gain horse power by having better flow….

To prevent the replacement of good components, be aware that the following non-EEC areas may be at fault: Fuel (quality) Fuel (octane) Basic engine Spark timing The knock sensor is used to detect engine detonation (spark knock). As a result, a voltage sent to the PCM will retard spark timing. The KS is a piezoelectric…
The Barometric Pressure (BP) sensor operates as a piezoelectric (pressure-sensing) disc. However, rather than generating a voltage, its output is a frequency change. The sensor changes frequency relative to intake manifold vacuum. The sensor frequency increases as vacuum increases. The BP sensor is used to sense the changes in barometric pressure, allowing the PCM to…
Both the ACT and ECT sensors are very similar. Before replacing either one, make sure the rest of the coolant system is in good condition. All of the following items will affect the ACT and ECT: Coolant level Radiator Fan Engine Temperature Water pump and Fan Belts Thermostat Engines general condition Harness and wire general…
A sensor is a device that checks a mechanical value and converts it into an electrical signal. It should not be confused with a switch. At times inputs will be referred toa s sensors, but this isn’t true. Some inputs have an ON state and OFF state, these are called switches. Switches come ON at…
Relays are meant to control electrical current flow. An electromagnet operates the relay with minimal draw through the switch. Relays are used in fuel injection to make computers cheaper and more reliable. The main computer has many jobs to do and can not do them alone. The computer sends small amounts of electricity to the…
Ford MAF cleaning To have the best performance and efficiency, the MAF (Mass Air Flow) sensor should be cleaned periodically, with frequency depending on driving conditions. Accessing the MAF is quite easy, and requires the same procedure as changing the air filter. Simply remove the clip that binds the MAF housing to the air filter…
The 5.4 3-valve engine found in Ford pickup trucks such as the F-150 has an irregular spark plug design which sometimes breaks during replacement, usually due to lack of regular maintenance at proper intervals. Because the spark plug body extends much further than the thread, there is an area for carbon, rust, and other things…
These have been given many names, but all identify the same item on the engine: Oxygen Sensor (O2) or (O2S) or (O2’s) Exhaust Gas Oxygen Sensor (EGO) Heated Oxygen Sensor (HO2) Heated Exhaust Gas Oxygen Sensor (HEGOS) Not all Oxygen sensors are heated, so using the word “heated” might not be correct for certain vehicle…
To prevent the replacement of good components, be aware that the following non-EEC areas may be at fault: Unusually high/low barometric pressure. Kinked or obstructed vacuum lines (MAP). Basic engine (valves, vacuum leaks, timing, EGR valve, etc.). The Manifold Absolute Pressure (MAP) sensor operates as a piezoelectric (pressure-sensing) disc. However, rather than generating a voltage,…

This device is referred to by many names, such as: Idle Air Bypass, Idle Air Control, Idle Speed Control, Throttle Bypass Air, Idle Bypass, Inlet Air Controller, Inlet Air Bypass, Intake Air Bypass, and Intake Air Control. The most popular being Idle Air Control (IAC). The IAB mounts on the side of the throttle body….
The throttle position sensor is mounted on the end of the throttle body and tells the computer how far open or closed the throttle is. The TPS is pretty easy to understand how it works, it is a potentiometer just like a dimmer switch in the dash. Voltage is fed to the TPS by the…
Ford EFI actuators overview Actuators are the components of the Fuel Injection that make everything happen based on commands from the EEC with the help of sensors. Following is more in depth information about each actuator and how it works. Exhaust Gas Recirculation (EGR) This air valve allows engine vacuum to open the EGR valve….
The EGR Vacuum Regulator (EVR) controls the opening and closing of the EGR valve. The EVR is an electromagnetic solenoid and should have between 20-70 ohms resistance between the pins. +12volts should be constant on one side from the EEC Relay, the computer controls the ground signal when EGR flow is needed. When the EGR…
The Vehicle Speed Sensor (VSS) is a small signal generator that is turned by a gear inside the transmission assembly. The Vehicle Speed Sensor produces 8 pulse per rotation which a stock computer assumes 8000 pulses per mile. The Vehicle Speed Sensor (VSS) is a variable reluctance sensor that generates a waveform with a frequency…
When it comes to performance and reliability in compact cars, few names stand out like the Ford Focus SVT. One of the key components that make this vehicle a favorite among enthusiasts is its robust Zetec engine block. In this blog post, we’ll dive deep into what makes the Ford Focus SVT Zetec block so…
Although the stock SVT rod (left) is well made, the Eagle rod (right) is much stronger and lighter, due to its H-beam construction, superior materials and ARP series 2000 3/8 rod bolts. The stock SVT rod is of a forged I-beam steel design with a pressed piston pin and is generally reliable up to 360+hp….

Ford mass air flow sensor This sensor uses a heated wire to actually measure the weight of incoming air. The cooler the wire becomes, means more air is passing it, into the engine. Once the mass of incoming air is known, calculating fuel ratio is almost perfect. The air mass is cross referenced with engine…
This sensor tells the computer engine rotation. But it’s a lot more than just a tachometer, it is solely responsible for three aspects of rotation: Revolutions per minute – engine speed and acceleration Cylinder identification – which cylinder needs spark and fuel next Crankshaft / Camshaft position – when valves are opened and closed The…
The Fuel Pressure Regulator is attached to the fuel supply rail downstream of the fuel injectors. It regulates the fuel pressure supplied to the injectors. The regulator is a diaphragm-operated relief valve. One side of the diaphragm senses fuel pressure and the other side is connected to intake manifold vacuum. The nominal fuel pressure is…
This page contains some modifications that were done to a Ford Windstar with a 3.8 Ford Essex engine for amusement. Not much was achieved as engine management was not touched and the transmission shifts too slowly to utilize any benefits. Essex 3.8 balance shaft elimination:This was probably the only modification worth doing, eliminating the balance…
The Ford MTX-75 (Manual TransaXle), is a 5-speed transmission developed by Ford Motor Company for its larger engined front wheel drive models. “75” refers to the distance in millimeters between the main and lay shafts. Debuting in 1992, the transmission was developed in tandem with the Ford Zetec family of engines. The transmission is optimised for transferring larger levels of…
