I have this sensor unplugged. Is there a way to defeat this sensor so I don't pull this code?

So I have a non ebpv pedestal I was going to clean my sensor on the front because my mileage has went down a bit. My question is is this even worth doing since the valve is not there anymore I have got mixed answers trying to look it up some say it still affects the mileage some say it won't. I cleaned it once about 10 years ago. I have an AE also how do I test it and what should it read if I do need to clean it or replace it?

Finally had a good scan done on my truck at the mechanics. The reoccurring codes were P0478 and P0470. It looks like a bad exhaust pressure control sensor. Looks like an easy fix.

I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?
Ford 7.3L Power Stroke (1999-2003) :: F350 - Heater Control Will Not Adjust
Heater control will not adjust, the one in the middle. I can turn it up and down, but it doesn't affect how much heat the heater is putting out. The other two work correctly. Do I have a bad switch or is the blender valve sticking? How can I tell? '99 F350, 1.25M miles.

What the normal tire pressures are so the TPS will not alarm? The sticker on the door says 65 front and 80 rear for my F-350, but I think this is a bit high when empty or not pulling trailers, etc. Additionally, is there anyway to adjust the TPS settings?

After running highway speed then stopping, the EBP valve is partially closing as you accelerate back up to speed. You can hear it in the sound of the motor, and you can see it on EGT's, which are rising quickly. This happens briefly then corrects. We unplugged the EBP sensor and the problem continued. Tube is clear.
If I monitor the EBP sensor, what values should I see if it is functioning properly?

Ford 7.3L Power Stroke (1999-2003) :: Boost Leak Through Valve Covers?
So I just put billowed up pipes and changed the broken O ring in the turbo housing. Put everything back together and checked for a boost leak with the home made tester. Boots and everything ARE OK. I can hear air escaping from what seems to be the valve cover or intake. I realize that I am charging my crank case as well but it still concerns me that air is escaping from somewhere besides the CCV. I read the following forum and this guy had the same issue and after he found out he was charging his crank case he was no longer worried. . . . .

After checking my fuel bowl today for contaminants, I put the lid back on and then noticed a leak from the rear at drain valve. I know, I already ordered the orings. It was doing one drip about every three seconds with the truck running. However, I turned the yellow thing a couple times and the leak stopped. Not leaking right now. Maybe it wasn't shut from previous owner.
Second question.....After stopping leak and after routing my fuel drain hose, I decided to give it a try. No luck. Nothing out or drain. Based on my first fuel filter change, it may be clogged up. So, do I run wire from the bottom up? Or do I run wire from top (bowl) down? Just so you know, sucked the bowl dry with a vacuum device before I reinstalled the filter.

Is this a normal find for you guys that have done injectors?

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time

View 4 RepliesFord 7.3L Power Stroke (1999-2003) :: Started Up After Cranking A Couple Of Seconds / Blowing Oil Out - Valve Cover?
I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?
Ford 7.3L Power Stroke (1999-2003) :: Low Power - Fuel Pressure?
Low power on my 2003 7.3 F350. The truck runs fine but I can tell it is low on power (seat of the pants). I figured it to be fuel related so changed fuel filter and oil with no change. When that didn't work I installed a fuel guage and this what I found. Key on no start fuel pressure 45 psi. Start truck the pressure will get up to 61psi. Under a load it will drop down to the low 30s. I have dropped the tank mixing chamber screens clean and so was the tank. Changed fuel pump and now under a load it drops to the high 30s. Does this sound like the fuel pressure regulator is leaking by and causing low pressure under a load? Truck is stock besides superchips 1705 programer.
