Test for EBPS
Just was wondering if there was a way to test the ebps. I pulled it and cleaned the tube(was about 50% stopped up and cleaned the end of the sensor itself. Thinking maybe best just to replace sensor. Appreciate any thoughts. Thanks, Bill-

If you have autoenginuity or another scan tool capable of reading live data you can watch the pressure. At idle there should be 10-15psi with it climbing on acceleration. Stock should see in the mid 40's, with my 5"straight pipe exhaust I see low 30's max. one sign of a clogged tube or sensor is very low numbers (3-4 psi) at idle and just barely creep up on acceleration.

Thanks for the help - My psd is pretty much stock now, but im doing the 6637 filter mod and the ccv mod this weekend. Would you advise replace ebps. Truck has about 78,000 miles now and the guy I bought it from wasnt too big on maintenance. Thanks, Bill Also thinking about 4 exhaust. I use truck mainly for towing a 9000 # pull behind travel trailer.

Alan you are saying it should read 10-15psi at idle with the EPBV open? My BP guage does not move at idle, and it barely creeps up when im just tooling around. Max i've seen from my 1.15 housing is 42psi.

Kris yes on the BP Valve open and with a stock exhaust system (turbo and pipes) yes, but you are very close to a 1:1 drive ratio with the 1.15 housing. 42 is not over the max stated by Ford, those reading from my mine are not WOT readings just normal acceleration/driving. Stock i could see mid to upper 40's and even some 50's with just normal acceleration.

My system with the current turbo setup does not budge the gauge at idle, barely at high idle.(1200). The EBP sensor reads pressure out of the exhaust manifold, correct. However one of the three main factors to produce boost is exhaust backpressure, and with the stock turbo, you will be running about 5psi of boost at 10psi backpressure. Since the engine is under no load and is not flowing alot of air at idle, i dont see how it can be 15psi. Maybe im still a

Maybe it's not a gauge 1 for 1 reading and those numbers are more for a scan. I don't know, but in the same way a gasser will produce a vacuum, even at idle half if 7.3 liters of displacement idling away will make some pressure. Now you have a gauge, and I cannot explain your findings until I run the AE on mine, and look in the shop manual.
