1 Oil level/temperature sensor 2 Openings 3 Oil dipstick The 135 PS version of the 2.4l Duratorq-TDCi in the Transit 2006.5 (at the time of going to press) is equipped with an oil level/temperature sensor. The quality of the engine oil is calculated using this sensor and a strategy implemented in the PCM. This measure… Read More »

The exact procedure for the correct installation of the fuel injectors can be found in the current service… Read More »
1 Fuel pressure sensor 2 Pressure limiting valve 3 Fuel rail The fuel rail performs the following functions: • stores fuel under high pressure and • minimizes pressure fluctuations. Pressure fluctuations are induced in the high-pressure fuel system due to the operating movements in the high-pressure chambers of the high-pressure pump and the opening and… Read More »
