    2017 Ecoboost with P051B check engine light

    Thanks for the response Tater. My CEL just went off again...before I have my appointment scheduled. I'm wondering if there's some residual oil/gunk somewhere that keeps triggering it, or preventing/causing too much crankcase pressure since the code says "out of range". I guess I'll wait to...

    2017 Ecoboost with P051B check engine light

    Well the CEL came back on yesterday. I guess I'll have to take it in to see if the dealer can figure out what's wrong. Grrrrrr.

    2017 Ecoboost with P051B check engine light

    Update: I ended up taking my existing PCV valve out, remove the tube and inspected. Both looked OK. The PCV valve sounded like it was working properly, I just reinstalled and put the tube back on. I went out for a drive, about 10 miles and drove it a little harder than normal, but nothing...

    2017 Ecoboost with P051B check engine light

    I ordered a PCV valve. I might order a new Crankcase pressure sensor if the PCV valve/tube doesn't fix the issue. On a different note, I changed the oil today, it looks like the dealer overfilled the oil the last time (though not by much). I got out just over 6qts. so that might have something...

    2017 Ecoboost with P051B check engine light

    Hi all, I'm hoping that someone could point me in the right direction as to where I can locate the Crankcase pressure sensor on my 3.5L ecoboost? 2017 Expedition EL Limited (64k miles). I have a check engine light and the code is P051B Crankcase Pressure Sensor Circuit Range/Performance. I...

    Park to Reverse jolt/shake

    Mine has been doing the same thing but it's the previous model, I have a 2017 EL with 6spd. and 60k miles. It wasn't doing it previously, lately, only when cold, it does it when I shift in to reverse and begin backing out of the garage. My garage is about 50-60 degrees or warmer all the time...

    Overheating ecoboost

    I researched the intercooler issue. Looks like even the 2017 ecoboost F150s have overheating issues up steep grades, and they are the gen 2 ecoboost. I researched a first gen ecoboost F150 owner who had the same overheating issues in hot weather up passes, it sounds almost identical to what we...

    Overheating ecoboost

    I'm not sure I agree with that LOL. I think more air = more gas = more heat. Don't the tunes typically add more boost....which adds more air (even if it is cold with larger intercooler), that means more gas and hence a lot more heat.

    Overheating ecoboost

    Yeah I was thinking about swapping the cooler too until I realized that it holds about 200 degrees without the trailer. It seems like they designed it that way. I think I read somewhere in the forums they don't even open the auxiliary cooler until 185 or so? Not sure if that's true or not....and...

    Overheating ecoboost

    Outside temp was in the 70s to 80s. also my transmission will see up to 210 or 212 degrees up i-70, though most of the time it hovers around 203, but that's what my 3/4 ton Yukon gets up to as well. Going from 4900ft to 11,000ft + is just not friendly to the drive train :).

    Overheating ecoboost

    My Ecoboost overheats too! I exhibit the same behavior as coolzzy on long steep grades with my foot in the gas. I just took my 2017 Limited Expedition EL on the first big test up the IKE Guantlet. I drove from Frederick CO, through Denver then up over I-70, then down to Silverthorne. I had my 4...

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    I took it on a drive Sunday up i-70 from just north of Denver, over i-70 and down to Silverthorne. It handled pretty well considering the IRS. It definitely didn't handle the sway nearly as well as my old 3/4 ton Yukon, but I expected that. Overall, it handled the rest of the bumps a lot better...

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    It's a pretty light trailer really, only 5670 dry weight. I'll know what exactly it is fully loaded here soon, but my previous numbers were just over 14,000 including the trailer loaded, yukon XL loaded with kids/gas and everything (paddle boards, raft, generator, food....etc). Just a ballpark...

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    Yeah it should be a fun exercise. When I just weighted our entire setup at the CAT scale last time with the Yukon, I only weighed everything together with the 3 axles. I was able to at least figure out if I was overloading the rear axle, but it would be better to know how much the bars are...

    Very nice....seriously low mileage too!

    Can I trust a 2015-2017 Expedition EL to be reliable AND to tow in Rockies?

    Sounds good...I have the 4x4 (that's about all the sell in Colorado anyway). I think I forgot about that being a modifier.

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    Thanks Shane. I'm assuming by 3 pass you mean....weighing my expedition with gas/kids/cargo by itself, then weighing the trailer uncoupled and loaded, then weighing them both together on the cat scale to get how it distributes weights on the 3 sets of axles? That is my plan, though I'm not sure...

    Can I trust a 2015-2017 Expedition EL to be reliable AND to tow in Rockies?

    Don't all ELs have the 3.73? That used to be the case anyway. All EL/Max have the 3.73 ratio (I thought). All Limited edition and higher have the HD tow package with 7-pin/larger radiator and aux transmission cooler. You can get the HD tow package in some XLTs, but generally when they come...

    Can I trust a 2015-2017 Expedition EL to be reliable AND to tow in Rockies?

    Thanks Jay, yes the warranty is weird. I bought it from a large dodge dealer here, it's not CPO, they just gave it a 2yr/100k powertrain as an additional perk to try to sell it. All of the other expeditions here in Colorado had no warranty unless they were still under the manufacturer warranty...

    Can I trust a 2015-2017 Expedition EL to be reliable AND to tow in Rockies?

    Yes...as Chuck said I'm using the Equalizer (4 point) with 1200lb bars.

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    Yeah compared to my old 2004 3/4 ton Yukon XL, the expedition wiggles a lot more in my testing on the interstate.....but it's so much more comfortable/powerful/better braking I think I can live with it (time will tell). My old Yukon is a beast though, I've taken this trailer to Yellowstone...

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    Hi Shane. Yes, while I was basically unloaded in the Expedition I was hoping to just get it corrected to not squat at all with the WDH setup, then when I load my family in there it'll squat some. I think it'll just have to do the way it is, I have the limited without the auto leveling shocks...

    Can I trust a 2015-2017 Expedition EL to be reliable AND to tow in Rockies?

    Thanks guys. I ended up picking up a 2017 limited that has a 2yr/100k miles powertrain warranty. We'll see how it goes, so far so good. In my test drives with the camper with some winds on the interstate, it wiggles a lot more than my 3/4 ton Yukon XL, but I expected that with the IRS. It...

    How does this setup look for weight distribution...anyone able to get no sag on rear?

    Hi all. I spent the better part of the afternoon transferring my Equalizer 4 point sway/dist hitch from my 3/4 ton Yukon to my 2017 expedition EL. I never felt like I was able to reduce the squat on the back enough...if I setup the WDH to put more weight to the front of the Expy, it would just...

    How much can I "safely" tow with 2016/2017 Expedition EL Limited with HD Tow Package?

    I think you will probably be just fine. The fact that you are concerned with doing it right goes a long way, and probably indicates that you are a safer driver and worried about the safety of others. I have a camper that is about 5670 dry weight, 33ft long, and I think the dry tongue is close...
