Step 3: How to tell when a DPFE sensor is failing. When a DPFE sensor begins to fail, it provides the PCM with bad/inaccurate data. This is because it is less sensitive and the PCM thinks less recirculated gas is being burned than is actually so. When this happens, the PCM adjusts the flow of the gas as a means of compensation and winds up I have discovered that when a code P2454 is stored, the powertrain control module (PCM) has detected a low voltage input signal from the circuit of the diesel particulate filter (DPF) pressure sensor that has been given the designation A. Only vehicles equipped with diesel engines should exhibit this code. Posted January 19, 2015. Took my car for a run with Forscan running and the DPFE reading is nearly always at 0kpa and rises occasionally to 1kpa, usually when it has risen to 1kpa the exhaust temperature is over 200º and drops to 0kpa when the temp falls below 200º. So If i am correct the sensor is reading very little difference in pressure I have a diesel Mondeo Mk4, 2010 reg, with an engine malfunction warning on the dash. The Ford IDS diagnostic tool reports the following two diagnostic errors: P2688:00-2F-PCM. Description - P2688: Fuel Supply Heater Control Circuit Low. Failure Type - 00: No additional failure type information for this DTC. Status - 2F: (Current DTC) Fault is Sensor, exhaust gas temperature; EGR cooler; Exhaust pressure sensor; Exhaust pipes; Mounting kit, exhaust system; Buy Dpf for FORD MONDEO online. Safe Order 200 After having a few issues with my DPF system (hopefully fixed with the replacement of a temp sensor) and over 200K km I am wondering if an occasional use of something like this would be beneficial. 2012 MC Mondeo LX TDCi Wagon - Highway Hack 392K km and counting - Now gone diagnosing a diesel particulate filter differential pressure sensor1: check voltage supply at plug.2: check hoses to DPF from the sensor for leaks.3: with th I imagine it's in the same place as minelooking from the front, it's mounted on the firewall/bulkhead behind the engine on the right side about 20cm down from the top of the engine (from memory) Mondeo 2.2 TDCI Titanium X Sport (2011 MK4.5), Panther Black | S-Max 2.5T front brake calipers and 316mm discs | Fuel Log Tl3mOdK.
