Unhappy Exhaust Back Pressure Sensor

I still have not been able to determine if my 2005 still has one of these and if it does I cannot find it. I have checked the 6.0 bible for illustrations and I do not have one where the drawing says it is. Can any of you shed some more light on this? My Dealer said mine was bad so I bought one to replace myself.
Thanks

Bruno;

I'm looking at the 6.0 bible pages that show the actual engine. It says that a EBP sensor lies at the front right corner near the secondary fuel filter. I've had some say that there is not one and some say there is. Hopefully a tech will chime in and settle this one!

I've read where the EBP is ignored with the later flashes, and that the info. is derived from other sensors now -- you shouldn't need to replace it, just have a later flash. I'll see if I can find that thread...

My bad -- looks like the removal of the EBP via progamming was for '03 & '04s. Depending on your mileage, fixing it could be covered under the emissions warranty or by a TSB or Recall. This is what I found: (good luck)

2004/05 Emissions and EBP Sensor Recall 05E15:
Certain 2004 and 2005 trucks are being recalled for computer reprogramming and replacment of the Exhaust BackPressure sensor and, in some cases, the EBP sensor connector. Econolines built between 12-9-03 through 5-28-04, and SuperDuties and Excursions built between 12-1-03 through 5-31-04 will have the EBP sensor connector replaced. SuperDuties and Excursions built between 9-29-03 through 11-30-03, or between 6-1-04 through 1-18-05, and Econolines built from 6-1-04 through 3-3-05 do not have the connector replaced. All of the above trucks will be reprogrammed to the latest calibration level. Since many trucks ahave already had the EBP sensor replaced with the current level part, the sensor part number should be inspected. If the part number on the sensor is 1850353 over a number starting with "C1", the sensor does not need to be replaced. Any other numbers, or unreadable numbers, will be replaced.

2003-05 Various Running Problems, Check Engine Light; New EBP Sensor:
Trucks built before 1-17-05 that exhibit buck/jerk, hesitation, lack of power, stalling, stumble, black smoke, surging, rolling idle, changes in engine sound at idle or when driving at a steady speed, or with the trouble codes P2263 or P0299, may have an exhaust backpressure sensor signal that is incorrect or erratic. A revised EBP sensor is available if this is found to be the case. Part number 4C3Z-9J460-A. Broadcast Message 3815.
Normal EBP signal reading should reflect atmospheric pressure with the key on/ engine off. Typically, this is 14.7 PSI/0.88-0.9 volts at sea level, decreasing one PSI/0.10 volt for every 2000 feet of elevation. It should be within 0.5 PSI of BARO and MAP sensor pressure signals.

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. Broadcast Message 1078/SSM #17573.

The My 05 does use the EBP. I have had to play with it many times due to the exhaust brake having problems with it. The sensor is a bit sensitive. Facing the side of the motor on the drivers side look at the font of the valve cover. On the drivers side you will see a tube coming up from the side of the valve cover. On the top of the tube you will see an electrical connector. That is the EBP sensor. There should be between 1.15 to 1.35 volts at idle. This is with the exhaust brake so the volts may need to be lower. I learned the hard way that when the sensor gives erratic volt readings to the PCM the turbo will act erratic and set codes.

Another good way to test it is to obtain a pressure reading at KOEO (Key On Engine Off). This is outlined in the TSB above. The EBP reading should be close to the MAP and Baro values (.5 psi); if you're seeing several psi difference, its most likely bad. There will be some slight variation due to mfg tolerances. The challenge may be having something that can read and compare them. I use the Autoenginuity software on my laptop. Without that, do the voltage check with KOEO.

I know some dealers don't effectively test this aspect and it got me a new reman. turbo when all I needed was the sensor - even after I told them my findings.

Finally found it. Below the coolant resevor and behind the master cylinder and mounted to the valve cover right where Tazo said it should be. Very easy to miss seeing this thing. Mine was totally plugged and gummy with black junk. Hopefully this will solve my turbo issue.
Thanks for the help!

Does anyone have the approx. cost of the EBP sensor?

The Sensor is a real ******* to get to and it might make sense to clean the metal line from the exhaust with carb cleaner once you have the old one off.

My engine light just came on right before the bumper to bumper ran out and of course, we are on the interstate, on Sunday with 200 miles to home! I took it to the local dealer and that's what they say was wrong with mine. And, of course, had to pay a $100.00 deductible but it is covered under the warranty. Told me it cost a $180.00 and it took them less than five minutes to replace it as I stood there and watched. So, with that in mind, do it yourself and save a few bucks if you can!

EBP Sensor Problem

Thank you Diesel Dan for your informative post on the EBP Sensor. This is the most information I have found on this subject.
My 2004, 6.0L, F350 dually has been giving me fits for about six months, dying, unable to start afterwards, sometimes vehicle would start but unable to accelerate. I had the Injector Control Module replaced and fixed some of the problems, however it still died on me last week again. The Ford place is telling me they found a bad EBP sensor connector and a wiring harness rubbed into the wires. Hope this fixes it.

Harness problems can give you fits and don't show up on the computer. If it keeps on doing it, come back and we'll help ya.
