Ford 7.3L Power Stroke (1999-2003) :: Exhaust Back Pressure Sensor
Jun 23, 2016
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 need to install an oil pressure sensor sending unit. I've already occupied the 1/8"NPT test port on the rear of the oil cooler, where else might I be able to tap into oil pressure? (LPOP)

I just had my turbo and the EBPV on the pedestal rebuilt. Now I need to put it back into the truck. What is the procedure, if any, to adjust the EBPV? I only use the truck to haul a 5th wheel RV and the performance chip closes the EBP valve when going down steep hills -( EXHAUST BRAKE)

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

I have a 2004 6.0 with 75000 miles on it. My truck is throwing a P0470 code pointing at the exhaust pressure sensor. my question is do I need this sensor or can i bypass it? When I look up the part it only shows 2005 and up.

I am installing a fuel pressure gauge into my 02 7.3 I went to the thread the sensor into the plug hole on the fuel filter housing and it wasn't threaded, turns out the sensor thread is slightly smaller and a different thread ... The directions say to install it into the filter housing or the lift pump ... So I'm assuming I have to go the lift pump direction of installing it but where the lift pump is or how to install the sensor into it while not throwing a code or causin problems ... A step by step and even pictures.

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?

Got a 'Tire Pressure Sensor Fault' message a few times on the way back from Florida. Tire pressures were all fine. Hate that it doesn't say which monitor has the problem. Anyway... it comes on, but after a few minutes goes back off. Saw it a total of three times over the course of 1,000 miles in two days. Is this the sensor failing and requiring replacement? Or is the system itself starting to fail? Would ESP cover this?

I just installed a new MBRP 5'' exhaust system in my 7.3. I have only put a few miles on the truck since it was installed and I now have a black thick oily residue in the tailpipe. The exhaust system had some sort of oil in it when it was shipped. I remember getting it on my hands when installing it. I think the oil in my tailpipe is just the oil burning out of the exhaust system which mixes with soot that turns it black. When I installed the new up-pipe, the exhaust side of the turbo was dry. Like I said, I haven't ran the truck many miles with the new system yet. A few friends of mine have looked at the exhaust and they think I have a bad turbo seal. I didn't have any oil in the exhaust with the old system. It was sry. My truck has 135,000 miles on the original turbo. I hope my turbo seals aren't bad.

Recently I came across a guy parting out his F-250 with a 7.3 powerstroke. Said it had a blown engine, and didn't know what was wrong, but oil was coming out of the exhaust.
My question here is why that's happening. I don't have any experience with the powerstrokes, so I'd like to know what the culprit is before I even consider buying it.

I own a e1999 Ford F350 7.3 4x4 with a Garrett GTP38R turbo. I have been having issues with very little power and pulled an CEL of P0221. I know it's for the APS and have been trying to trouble shoot it as a new APS has not fixed the problem. However, while working on that I just noticed an oil leak appear. I tracked it down and can visibly see it leaking out the top of the passenger side exhaust manifold in two places. It is seeping out the top. Is oil supposed to even be running through here like that?
I recently replaced my up pipes with the newer style bellowed ones. While I had the turbo off I replaced all the o-rings top and bottom and did the EBPV delete on the pedestal. I have been having very little power and cannot the truck over 5-10 MPH and stays at low RPM's so I originally thought it was the leaky up pipes. Those were fixed along with fuel pressure checks which came back good. I then pulled the P0221 code finally. While I had the turbo off I inspected it and it did spin freely and had no side to side play in it.
What was unusual to me was there was a small pooling of oil in the turbo when I took it off. I know the CCV goes through here so some oil is normal. Also, when I was diagnosing the up pipe leak I could see a small amount of oil spraying out the blown donut gasket along with the exhaust gases. I don't think that is normal.
Is there an internal seal in the turbo that can go bad causing oil to spill into my exhaust and possibly leak at the exhaust manifold? Or do I have an internal oil leak from somewhere else?

New up pipe and manifold gasket time!
Massive exhaust leak.. Likely the reason for my 5psi boost.
Wish I had the funds for headers but on the up side, no broken bolts!

i have a 99 f250 7.3 powerstroke. the cam sensor was acting up. that what the scan tool said. i replaced the cam position sensor yesterday, and the truck is still acting up. the motor hitches and will shut off randomly. it tripped the check engine light, and the code is the "cam position sensor" once the truck is warmed up and shut down for like 10 minutes the sensor will not act up anymore. if i just start the truck and run it, even once it is up to tempature it will act up. but if i shut the truck down for about 10 minutes, it goes away. is there something else that could be causing this?

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.

My high pressure power steering hose just blew at the "B" nut at the pump. Meaning, the fitting is still in the pump but the line is out. Do I need to replace the whole line or is there a retainer I can swap out?

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

I just replaced my 3rd HP power steering line last night( 3rd in 300K, always blows the same point....fitting comes apart where it attaches to the pump.
I'll start, mine have gone about 100K plus or minus 10K, almost thinking about making it a 100K maintenance item.

I'm at 76K miles and I had another exhaust sensor go bad. This time the check engine light came on and the truck did not shut down. I was prepared this time and had an extra sensor / code reader handy.
It was the last sensor in line and very easy to get to. It took me less than five minutes to complete the job. I did use anti seize, but as easy as it came out it probably wasn't necessary.

I have a 2000 f350. Lost power whole driving and won't start back up. I have checked all my fuses and relays several times. Have no power to the fuel pump. Tried running a hot wire straight to the pump and still nothing.checked my emergency cur off switch and there is no power there. Also my WTS light isn't coming on now. Tried checking the heater bowl and no power there.

I just bought a 03 7.3 Ex w rebuilt motor done really nice .. it has a Terminator HPOP .. and pressure spikes to 80/85 on cold startups and spikes until engine warms up .. engine only has couple thousand miles on it .. is that normal ??
