The MAP sensor is then used for rationality checks and to test the EGR valve. The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and ...
PCV valve on Ford Taunus V4 engine (feeding from left side valve cover into the inlet manifold) A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold).
The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company. The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
Built at Ford's Dagenham engine plant in Essex, the 3.6-litre V8 twin-turbo diesel engine began production in April 2006. The 4.4 L variant is built in Ford's Chihuahua Engine plant in Mexico . Much speculation in the United States has focused on this engine as a possible Diesel entrant in the F-150 pickup truck and Expedition SUV. [ 2 ]
The high amount of heat in this location, combined with the exposure to debris in the oil was known to cause ICP sensor failure also resulting in a no-start condition. This issue was addressed by Ford with the late-2004 engine update, bringing a new HPOP design, along with relocation of the ICP sensor to the passenger-side valve cover.
The Ford Duratec V6, is an aluminum DOHC V6 engine with a 60° bank angle introduced in 1993 with the Ford Mondeo. The primary engineering came from Porsche , [ 1 ] who was developing this engine before selling the engineering to Ford, and Cosworth , who helped with cylinder head manufacturing. [ 2 ]
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
The hot film MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal. This sensor uses a hot film-grid instead of a hot wire. [3] It is commonly found in late 1980s and early 1990s fuel-injected vehicles. The output frequency is directly proportional to the air mass entering the engine.
