Welcome to the club... I'm currently dealing with that right now. Unless I find an answer this weekend, shes going to the dealer Monday. I'll let you know what they say.

I would make sure the exhaust pressure sensor is plugged in first.

[08powerstroker64]

where is that plug located?

[ajpu1983]

The exhaust pressure sensor will be connected to a steel tube that runs to one of the exhaust manifolds and reads exhaust pressure. Look at the manifolds and look for the small pipe that goes to a sensor. I believe it' on the drivers side. 3-wire plug like the ICP sensor

I just got mine out of the Ford shop today with the same problem. Today, while driving, I suddenly got what felt like a clogged fuel filter or bad injector(s). The symptoms were sputtering and poor fuel delivery when on the trottle. While this was happening, the check engine light came on and I limped in to the dealer just barely. It turned out that a P0472 code was thrown which is the EBP Sensor (Exhaust Back Pressure). $425 later ($174 for the sensor and wire harness and rest for labor OUCH!) the problem was fixed. What happened was one tiny wire on the clip harness going into the sensor chaffed and caused the sensor to "think" that there was TOO HIGH exhaust back-pressure and in turn, sent a signal to the turbo telling it to back off and thus no turbo and air mixture being rammed in causing the poor and speratic throttle response.

I have the same problem with the sensor except that my turbo went up to 40 psi and blew the hose off. so I went and got the part from ford for $100 part that is made in Mexico. So this will be my last ford

Might want to clean the EBP tube. Sensor and tube are on driverside. They can tend to plug.

You can try this too.

ICP/EBP Sensor Repair Kit:
Both PowerStroke engines may exhibit codes related to the ICP(7.3: P1280; 6.0: P2285) and/or EBP sensors (P0472). If these codes are present, clear them. Start the engine and wiggle the sensor connector that matches the stored code. If the code returns, replace the sensr connector--P/N 3C3Z-12224-BA for 94-96; 3C3Z-12224-AA for 97-2004.
