EBP Sensor
EBP
Now I have always had a little problem with the Inferred EBP. I know the Ford documentation concerning it and have a copy of the TSB,
My problem has allways been that if only inferred data is used why do they keep the sensor and leave it plugged in.
Secondly why if you have problems and clean the sensor and tube or replace, why do the problems useually resolve.
I have worked on a lot of 03/04 trucks and while watching live data or logs the cleaning always improves the readings.
Something from that sensor has to come into play. Exactly what I do not know.
If anyone does know I would like to hear it. It would clear up a lot of confusion my own and everybody elses.

From what i know the EBP sensor monitors boost, without it working or clogged can cause overboost. In 2005-07 models with the latest flash, the EBP sensor can be disconnected if needed because boost data is gathered from other sources and not solely the back pressure sensor. dont quote me on that though

The EP sensor DOES NOT monitor boost. The sensor measures exhaust pressure in the left side exhaust manifold and its data is used to control the turbocharger and the EGR valve. Boost is monitored by the MAP sensor. With the Inferred EBP calibration the EP sensor is still connected and live but the data is no longer used for turbo and EGR valve operation. Because the sensor is still connected, certain faults with this sensor or its wiring that can affect VREF in particular is going to cause problems - specifically with the EGR valve position sensor and the ICP sensor because those three sensors share the same VREF circuit from the PCM.
As far as replacing or cleaning is concerned I too would think that this would not necessarily have any affect on the engine. We are told that the EBP readings are not used by the PCM but we had a discussion about this on the DTS forums some time ago. We suspect that the PCM still monitors the relevant circuits and the sensor for proper operation. That might explain your findings. You will not find anything in print on this beyond the recall notice that brought this inferred EBP calibration to us and the two accompanying reference guides.

well i was half right, in the newer flashes it doesn't do anything for the turbo. Mine is unplugged right now simply because with it plugged in my truck surges at low rpm/High boost, cant explain it, but i dont want to spend the money right now
