EBP Sensor Info - Diesel Forum

Hi Everyone,

When towing the 5th wheel I would get the "turbo fart, chugging/jerking, turbo gauge fluctuating rapidly" problem and am taking it to the dealer in a couple days. I talked to the shop forman and he told me that I will get a new EBP Sensor, something regarding EGR, and maybe a reflash. He told me they got a new flash a few days ago that works on all 6L from 03 to 05. Anyways I would like to know if anyone has gotten the new EBP sensor and if it fixed the "jerking and turbo fluctuating". Also does anyone know what the new flash that came out does? I am worried that if they flash it my mileage will go down. Thanks for the info.

Most likely turbo vanes stuck.

I just had everything you said done to mine. And it runs beautifully. I do think however that the new reflash did slow it down a smidge but the driveability is wonderful. Mine used to dump a bunch of blue smoke at idle and jerk an jump and now it's a Caddy on 38's.

I just had mine reflashed with the latest for a "Romping/Bucking and jerking issue. It made the engine quiter and seems to be giving me better mileage. However, it has not solved my romp issue. I am at about wits end with the romping. It gets down right dangerous, I feel like I might run someone over if I'm not paying attention. I think if these techs would actually take the time to diagnose the problem instead of just doing a reflash everytime the 6.0 farts we all might get somewhere!

gawent - what oil weight are you running. If it is the 15-40 switch to the 10-30 and see what happens. This really helped mine, especially on cold mornings.

Now to the issue here I found this on the dieselmans site

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.

also this

2004 F-Series and Excursion Built After 9-30-03, Various Driveability Concerns:
Trucks that exhibit surge at idle, changes in engine sound at idle (EGR cycling), low power/smoke/rough idle on cold start that corrects when engine warms up, surge when selecting resume on the cruise control, flutter noise from engine just before transmission kickdown, buck/surge on manual transmission, should be reprogrammed with the latest calibration. This program includes a reduced EGR valve on-time during extended idle. The WDS must have release version 36.10 or higher, or 37.10 or higher, but not version 37.0 to have the correct calibration update. Broadcast Message 4118.

here is the direct link - good reading

Hope this helps
