The DPF Pressure Hoses fitted on the Ford Mondeo IV and its derivatives are prone to premature failure. These vehicles are fitted with a pair of rubber hoses which run to and from the exhaust system either side of the DPF. These allow the connected pressure sensor to monitor the pressure differential either side of the The manifold absolute pressure (MAP) sensor, located in the intake manifold of the 6.7 Powerstroke engine, measures the pressure inside the manifold. This sensor plays a crucial role in optimizing engine performance by providing data on intake air pressure. The ECU utilizes this information to adjust fuel delivery and control the turbocharger The pressure sensor described underneath is mainly used to monitor the soot loading of a particulate filter on a diesel engine or gas turbine. The signal of the sensor is not sufficient to determine an optimized timing for regeneration of the DPF. It is part of a soot loading model that should be calculated permanently by the ECU. The DPF supervisor module is a sub-system of the DPF co-ordinator module. DPF Fuel Management Module. The DPF fuel management module controls the following functions: Timing and quantity of the 4 split injections per stroke (pilot, main and 2 post injections) Injection pressure and the transition between the 3 different calibration levels of I would recommend all owners of a Ford car to install Forscan on their computers or download the app as it really gives you some tools for diagnosing/fixing problems yourself. 2. Added Wynn's DPF cleaner to fuel tank and took car for a run at high revs down the motorway. I recorded live DPF pressure sensor and it reached 40kPa at one point. Attach the hoses to the sensor as normal. Now remove the rubber vacuum hose from the top of the EGR valve diaphragm. With the truck running apply slight vacuum to the EGR valve and this will open the EGR valve. When the valve opens you will see the voltage on the top wire of the DPFE sensor change indicating flow. IHuxAP. The assembly uses two NOx sensors: the first sensor (referred to as NOx sensor 1) is located near the turbo downpipe and measures engine-out NOx. The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst. The SCR assembly contains a catalyst brick that requires DEF, or diesel exhaust fluid, for activation. bsp01 Discussion starter. 3 posts Ā· Joined 2015. #1 Ā· Aug 22, 2015. Hi all, having trouble diagnosing this issue (see link). I've inspected the hoses and sensor and nothing seems out of the ordinary, except for a hose clamp missing on one of the pressure lines, to DPF. I can't imagine that would be the cause, however I will add a clamp. The 6.7 Powerstroke exhaust back pressure sensor is located on the driverā€™s side of the engine, behind the turbocharger. It is mounted in the exhaust manifold and measures the pressure in the exhaust system. If you have a 6.7 Powerstroke, then you know that the exhaust back pressure sensor is an important part of the truckā€™s emission system. vaporiser was cleaned too. The engine didn't even got up to temperature. I have checked the voltage on DPF pressure sensor. Reference wire shows 5 volts and signal wire 4.75 volt with ignition i n accessory mode. When sensor is disconnected both wires show 5 volts. Hi, Iā€™m hoping someone can help as Iā€™ve almost gave up! My 2013 titanium x went into limp mode due to dpf and wouldnā€™t regen, so I fitted a new dpf, disconnected battery to clear computer and the thing is still in limp mode with exact same fault code..
