Changing the DPFE Sensor (Delta/Differential Pressure Feedback EGR Sensor) Most shops in Dallas will charge $280 for parts and labor, but the Ford Factory pa 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 Since the DPFE sensor relays information to the PCM, the latter can activate this warning light if the sensor is sending irregular signals or isn’t sending information at all. Keep in mind that more than one issue can trigger the check engine light, so it’s best to check for other symptoms before chalking it up as a faulty DPFE sensor. . The fix is an oil & filter change and an ECU update, they say. The service manager says it's an oversensitive sensor relating to the DPF, which reports the oil has become contaminated and is putting the DPF at risk. The ECU update is supposed to reset the parameters for the sensor. Oil drop, filter & update is free, under warranty.

I connected Forscan and it gave me a code saying the Oxy Sensor was failing but I didnt note the code down and since the the following codes appear: ===PCM DTC P246B:00-2F===. Code: P246B - Vehicle Conditions Incorrect for Particulate Filter Regeneration. ===PCM DTC P2463:00-AF===. Code: P2463 - Particulate Filter Restriction Depending on the vehicle, a certain DPS threshold may trigger a DPF regen cycle, but only if conditions are right. Some vehicles may trigger a DPF regen cycle around 15% capacity, for example. If conditions are insufficient for a DPF regen cycle, the DPF simply continues to collect PM emissions until they are. 2008-2010 Ford F250, F350, F450, F550 Superduty 6.4L Powerstroke Diesel Particulate Filter Pressure (DPFP) Sensor AP63473.
