7.3 EBP Reading

This is more for the tuning guys, but whoever knows, idc.
What does the EBP do to fueling?
And does the PCM have a default value for the EBP sensor if you unplug it?

Reason I ask, my tube is clogged as effh, and just barely cracked. I'm sure it's been like that forever, so not like it really matters.

Your fuel economy will bite the dust, i dont know EXACTLY what it does to fueling but basically it uses that tube/sensor to read the backpressure and based on that it fuels or defuels. with a clogged/unplugged sensor the engine thinks theres no backpressure so it injects excess fuel into the engine to try to up the BP thereby basically wasting fuel. Someone more knowledgeable can chime in but thats my understanding.

Well the extra it adds is probably very minute at most so maybe its just mistaken for a lead foot but enough to tank your mpgs

You can say that again on another note i see you still have the paddle mirrors on ur rig, you interested in my tow mirrors im puttin a set of 08s on it this week hopefully if i get it back from the shop. They only have a small crack on the drivers housing and the black is rubbed off a bit where it slides in and out.

idc you keep bumping it up

I left it unplugged and the sensor off in hopes it'd blow the tube out
I was wondering if it's like the ICP sensor being unplugged. The PCM just inputs a default value for the missing data so it can run. It seemed to run fine, but just maybe a little different. Idk, hard to tell.

My mileage is around 15.5 with tube clogged and tiny hole/crack.

true

But yea i mean depending on what lift/tires/mods you have thats a pretty average mpg but from what i have read its alot better to have plugged in and working correctly. A new tube is like 50 bucks so you can go that route if you want or just clean it and repair the crack. The sensor is the part that is outragous. its like 200ish for a damn sensor but at least yours works
