location of the exhaust pressure sensor on an '04 6.0L?

[jtlobster]

Anyone know where the exhaust pressure sensor on a 2004 F250 6.0L is located? I thought it was back near the turbo somewhere but my buddy said it was up near the front right next to the thermostat housing. I'm getting a P0420 code for EP circut fault. I think the tube and/or sensor are clogged or the electrical pins are correded. Any help with it's location would be great. Thanks.

Take the the air box off and the cold side intake tube then its real easy to see and get your wrench on it. IT sits up high in front of the Left engine valve cover. There is a metal line running from the left Ex manifold up to a fitting that the sensor screws into. Take them all loose and clean them good. Only took me about 15 min tops good luck
