I am impressed with the fact you took the time to look for and locate the problem other then removing and replacing components trial and error until the problem is found which is the case a lot of times in the area I live.
A true mechanic.
Not many guys around like you. Good job. Thanks from Green Bay, Wi
I like your approach; it's the one I used to fix a Chevrolet the dealer wanted about $5,600 to $5,700 to throw parts at, with no guarantee of a fix, after screwing up a warranty repair.
This literally just happened to my 2005 F150 Lariat with the 5.4 Triton. It has been sitting in my driveway for a few months as we picked up a newer 2016 F150 XLT with a 5.0 Coyote engine, which we love. At any rate, the battery was dead so I boosted the battery and it started up just fine. Ran it for a few minutes then decided to take it for a drive to charge the battery further and didn’t make it 400 feet when it started hitching, lost power, then stalled on acceleration. It started up but sputtered and stalled several times. Then the engine light came on and the engine safety mode display appeared. It finally ran long enough for me to put it in reverse and idle it back into my driveway. At any rate your video was incredible and really answered my questions in a hurry. I’ll keep you posted with my findings. Thanks again.
Hey thank you for this video, I just found this tonight, my truck did the exact same thing and had the same codes and the same melted 02 sensor. I was just about to buy a 250 pcm thinking that was the problem, I already spent 200.00 replacing the VVT sensors and cam sensors, this was an amazing walk through video you saved my truck and wallet man. I will be changing the fuse in the morning and driving to work. tomorrow.
I have the same too
Dude, you rock!!! I have a recently purchased 2008 ford expedition with EXACT same codes as you show here. Turns out fuse 74 was a bad fuse that someone tried to jump with a bit of copper wire! Replaced it, reset PCM and now running like a dream. Hoping the short doesn't come back, but now I'll know what to go after if it does. Kudos!
Good job man I love watching someone who knows what there doing. A lot of people would just start replacing seniors or fuses and be no farther ahead . Your a dam good Mechanic
Such a quality mechanic with great logic is rare to find and this guy shares his secrets?!? you have done this world and DIY guys like myself the biggest favor ever! I can't thank you enough Will!!!
l
Excellent tutorial!!!
No bs, just getting into the "Nuts and Bolts" of it.
Omfg thank u very much for your help. I threw every code. I did a transmission swapp and well thanks to u I had 3 burnt fuses. I replaced them. Rest the system and now my 02 f150 4.2l v6 is running like a mule/champ.
This has made my day..
Once again thank you very much for all of your wise wisdom.
You saved me another expensive cost.
Flaco753b fantastic!!! Glad to hear it
First off I just want to say thanks for all your help. Now what I did from all your help was I unplugged all the sensors and checked all the wires and made sure nothing was rubbing against any part of the chassis our exhaust then I put a Fues that I made with 2 wires on each blade then I got an old brake light socket then I solder the wires to the end of that, as well as the fuse and stuck it inside were the fuse go then I plugged each sensor one at a time until the light started to shine and that’s how I found out that the park behind intake manifold that opens and closes these two blades was bad the cmcv actuator and I also did everything you did in this video as well thank you 🙏 so much
Great video!! My 2005 F150 (215,000 miles) went into Limp-Home mode last night. Multiple codes. I’ll be troubleshooting this morning.
2023 My 2007 Ford F150 5.4 3v.
Same issue, same codes.
My fan clutch seized and took out its own sensor wiring.
Split the serpentine belt.
Again same codes you showed. Replaced cam sensors and connection wiring. Been in failsafe for 2 weeks. Was about to drop 350.00 on new fan clutch and VCTs.
Just found this video.
Short occurred from fan clutch failure tearing out its harness. Thank you very much.
I have been looking for this video for a long time after watching it and subscribing but couldn’t remember your channel name. So glad I finally found it again such a good way to chase down a wiring issue with multiple things on one circuit.
Just found your channel and subscribed. Great stuff! You and Eric O. over at South main auto are the best on RUclips.
Great video. Had come the exact problem. You faced my truck from being by burned. Great step by step for those who don't understand be trucks too much
Great diag, I appreciate true professionals who do real work and put in the time. Nice job.
Thank you for the feedback and compliment its appreciated
Thank you so much to show me about this problem my car he was dying every time when I stayed the break now I saw the ABS sensor on the passenger side is touching the exhaust manifold burning that wire in Now I replace the sensor car working really nice
Nice work!! I have a 2016 Escape S/2.5 that work provides me and it had the throttle body fail while I was on the interstate recently. Kinda the same thing, just dropped right out...made for a scary situation for sure trying to get off the road safely with nothing but a stumbling idle left. Nice to see you back.
Thank you, man the interstates no joke scary thought, made for a bad day im sure. thanks again glad to be back
Great video guy I love your logical thinking and the tree diagram was great, makes the system easy to understand.
thank you sir. this is exactly the same faults i got as well. i was literally looking up each code to replace every sensor and making an amazon list until i stumbled on your video. LOL! a freaking fuse.......now to trace where the short is, thank you for saving me alot of time, aggravation, and money!
Great diagnostic techniques and good schematic familiarity resulting in a speedy repair resolution and quick turn around time to the customer's satisfaction.
Thank you for the compliments, i appreciate the feed back. whenever someone questions what they can do to become a technician i always say learn to follow electrical schematics, my most passionate aspect of the job
Great video. You’re an awesome teacher. How do you fix the P1664 (KAP) code? On a 06 mountaineer?
Very intelligent analysis..wish local mechanics were as professional..i can trust someone like you
After watching this video , I figured out exactly my problem, awesome and informative video , saved me a lot of money
Great Video. I just saw a tool for the first time this year. 2020. They have DC current clamp meters now. and some with Bluetooth. It would really help isolate the branch of that tree that was shorted. even used it to check battery charging.
Good video Will! Great to see you back on here!
Thank you, im glad to back back interacting with you guys. im feeling motivated again, i may need a little push on occasion lol i really do appreciate all the support
Whether this works on my 5.4 with same multiple codes, almost the same as his or not, what a great informative video.
Great job man! You just taught me a ton!! I just had a check engine light come on with like 5 different things, truck runs great but it's got to be something like that, it's saying tps, throttle body, vct solenoid, camshaft sensors, which i replaced and cam shaft sensor connector, which is in bad shape, im replacing that next, I don't see HOW all that could be wrong at once!!???
You was very articulate and saved me tons of work. Thanks so much!
Nice one Will , excellent diagnostic process . Always nice to see a new vid from one of my favourites. Cheers buddy.
Thank you, appreciate it bud. would kick myself In the a## for you guys if I could, I regret not making more time. Most likely be Further by now. Thanks for sticking around. nice hearing from you
From my point of view you are number one in my book as of now thank you sir.
Thanks for this video, I'm about to work on my 5.4l right now 🫡 I'm also currently down to one spark plug to replace the left side #4. What a pain 🤕
Great job and great diagnostics . Thanks for posting the video.
Sir I am so grateful cause u just saved me for 3 days stress and continues research
This video is by far the best mechanic video I have ever had the pleasure to watch. I watched it several times simply because I didn't want to miss one word of your teaching. This was unreal to me. I am a pretty good mechanic but not certified. I can find the issue unless it is something like this. Thank you so much for this. I learned more from this one video than every video I have ever watched combined. Thanks again. Maybe this will help me in my search to finding out why my 2001 f 150 5.4 has just lost all power on the driver side. It is firing on taht side. But the whole side isn't hitting on the cylinders. Thank you again and I will search your page for one to help me further.
agreed
He's back!!!! Good job Will. Glad to see another video
I'm here to stay now bud, got to caught up elsewhere if you know what I mean time to Focus on better things, thank you for the compliments
@@robinsonsauto MANA WAS NO EXCEPTION
1st. Class tutorial and some very logical questions,answers, and good camera work. Appreciate your talents.
Very well done very informative of how the control system operates.
Amazing. Thank you. I just fixed my f150 thanks to you. I was panicking and lost with what the problem could be

Did your F-150 simply say Failsafe mode?
Man thank you so much for sharing!!!!!
Straight up the exact thing that happened to me on the highway! I checked that fuse and it was blown... checked o2 sensors and the driver side wires were laying on my muffler melted! Truly can’t say enough thanks as I was stressing about the cost of this.
Sir u are the best teacher ever so far
Decent diag. Eric O will be salivating. You guys are cut from the same cloth. Really enjoyed!
Thank fixed my problem. Great video now to look for the wiring diagrams you had.
Thank you so much for this video. I was going to go nuts trying to figure out I could drop 11 Trouble codes at once. IT was Fuse 32 blown, though I haven't figured out what caused it yet.
Ever figure out blew the fuse? Thanks
Great video! I’m having a different problem where it just stalls on an 06’ 5.4 . It does this several times a day and the problem is I haven’t found a great mechanic. You know electrical and that’s worth a lot of money. I hope to find a great mechanic somewhere in this big city of Houston. So many mechanics but less than 1% know how to find complex wiring issues.
Nice to see u back miss ur videos for a while there !!!
thank you bud, nice hearing from you hope all has been well
Gonna try your techniques tomorrow. Great video & thanks a lot
Great troubleshooting explanation and demo. The troubleshooting tree is very helpful. Too bad ya can’t smoke the tree after the fix! 🤟This diy thanks you sir !
thanks for your help. looking forward to your input on other problems
Awesome awesome job on diagnosing the issue. Love the fact that you're gut was telling you there was another hidden issue and you didn't give up on it!!! When will you be in the Orlando area? Could use your "gut" on my f150
Awesome job of troubleshooting and repair
I Agree " well done with the time you took and showing your process...
Excellent work as always. Thanks Will.
Thank you, i appreciate the feedback. hope your doing well
Fixed my Problem...
With Your Diagnostics tips
Thanxxx...
Wow! That was a very helpful video and gave me good direction on how to locate the problem.
Nice job.it seems like you're well educated. some Mecanics wouldn't found the issue. Some of'em just by changing a tire or a oil change. they think they R already a Mecanic. I take my hat off to you👏👏👏👏
Man you’re awesome I’m getting all these same readings on my F150 my truck has no power what so ever
100 % what mine was....saved me alot of time!
What year was your truck ?

I have had o2's that folks have changed and never put the harness back like that , Easy but MADDENING !! Thumbs up .. I just subbed to yur new channel ..
Same here, see it way to often, I appreciate the feedback and kind words, thank you
thank you for subscribing bud
Hey Will and hope you're doing well! You did a very nice job in diagnosing this issue and came to the problem pretty quickly. Keep up all that good work and try to stay cool as it's hot as hell down here LOL...take care my friend...
things are going well, Hoping to make a move here shortly if things work out. I'm trying to stay cool lol it's hard with the bay doors open, then the fan off while recording 😰 gets brutal
Excelente, super excelente !!!!!
great video the same exact problem just happened to my 2006 f150 5.4 replaced 02 senser anr runs great Tnx this video was a GREAT help!!!
Cheers
chris scordino did you have the overheat issue?
did it throw that many codes as well? I am currently researching almost the same exact problem maybe give or take a few different codes. My nerves are shot!
Awesome professional video. Subbed!
Good job love the way you diagnosed it excellent find and vidio
Glad you enjoyed it! Thank you for the feedback
Thanks for the video, very clear and good knowledge for any vehicle. Although when you went to pick up a new O2 sensor to 'be on the safe side', did yours not work or just being safe? Just curious as you put a bit of effort getting the one that day.
Solid video this knowledge alone will make you subscribe outstanding job!
Great video. I'm having the same issue with my Ford F250. I'm going to follow your lead and see if I can find a short in the wiring. Very informative video. Thank you.
Nice diagnosis & repair Will!
Thank you
Nice Really good quality work solid mechanic 👍
Badass man these are all the code my f150 is pulling up
Thanks for posting the video.
Thank you. I have Expedition 2005. Have similar problem, but it exists only if is over 80 degree outside. When is colder everything works perfectly. When is warm, I can drive for 10 minutes and the car goes into the safe mode showing p2107 and p2110. I could turn off engine and on again to make engine working normally, but only for minute or less. Sometimes, even it is little colder outside, but I left car with turned off engine for few minutes only, the error shows again and engine is in safe mode. If I drive, the wind cools the engine a little, but parked for few minutes or being in traffic generate error again. Entire summer I had this problem; Winter time everything is ok. Many things replaced and checked without any cause found. Currently, driving for long time in safe mode (I don't even bother erase the codes) I got 2 more codes; so, I have now: 2104, 2107, 2110 and 2112. Again, I am 100% positive, this is caused by the higher than 80 degree temperature and after few minutes drive. Do you have any solution for this? Thank you again, your video gave me some more ideas to check and maybe fix the car.
All your Codes Are TACM Codes --Throttle Body Actuator Motor
Disregard all of them
----Your Problem is Failed Cop Ignition Coils---
The Secondary Fails in many different ways & sometimes fails
to ground out in the PCM Drivers & that spike comes back to the
TPS Sensor
When you loose the tsp, the pcm doesn't know what the driver wants
to do & it sets any of those codes & goes into ETC FailSafe
You Do Not have a throttle body issue with the tacm motor
If it was bad you can scope it like a fuel pump & they are avail
separate from buying the entire throttle body such as my Lincoln L/S
There is a computer, so to speak, inside the PCM called an EQuizzer
that tps throttle signals go thru & unfortunately the spike from a
very bad ignition coil-- back feeds
So find & replace all bad coils,look at Mode $06 Data under cylinder
misfire counts
If you have to-- just walk a new coil,replacing the old one, until you get
to the bad ones
The only effect the temp has -is that to use it as a diagnostic tool, you
need to be at 90 degrees & that is no guarantee they will fail
Those 5.4 from 2004 thru 2006 had bad injectors as well,that leak
So between you driving in failsafe & the cylinder misfires your not
aware of,your pretty much going to have failed Exhaust Converters
The ETC or Fail Safe is there to protect the converter & your to stop
using it immediately, as the fails safe indicates a Class A Cylinder
converter damaging misfire
You never clear codes or you loose all Mode $06 Data,Freeze Frame
at the time of the event & other data needed & then have to drive until the Emission Monitors run again & if you have problems, they won't. So now you see why shops don't know this stuff,including dealers, that power brake the vehicle hoping to get a misfire
For the DIY --just replace the spark plugs & all coils & the front 2 oxygen
sensors & most likely the failed cats
Have to look at the O2 & fuel trim on a scan tool & inferred cat temp etc etc
gracias por este tutorial...save my day
Wow I thought my main computer went bad. Thanks so much!
Great video I got a question for you does the cam sensor it’s feed by the same fuse #32
Hi you, thanks for the sharing; best regards of Mexico
Super great video
thanks for uploaded
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Boy its nice when you see a problem like that and know its been found.
Dude thank you sooo much I was about to replace my engine 🙏🙏🙏
Awesome. Very helpful. Ty so much.
my fuse was ok. yet this has been a vary helpfull video.
Thank you so much for sharing...
Good troubleshooting!
u rock with this video, thanks a lot
Good information thanks. You may have mentioned this in other videos, Can you tell me a little about the Iphone/ Ipad diagnostic tool you are using in this video? I see several Bluetooth tools on the market but its hard for us shade trees to know what we are buying. Thanks.
Fixed my problem . Thanks !!
I just did a axle swap, I had 3.27 gears in the car , the new to me axle is 3.73, The 1st test drive I got about 100 yards and the car went into limp mode the wrench came on & the CEL, and the engine seemed like it was flooding or running on a cylinder down, Trouble codes: P0104, P0122, P0223,P2106 and P2110, P0113 and P0114. I'm on disability so I have no money to go have a tech look at it, Is there anything I May have overlooked ? ANY INFO or help is very much appreciated. I have no idea why all those codes came up, It drove & ran Excellent before the axle swap.
best video, very well-done, thank you. have a question, I'm here bec this happened to my truck but it was off a cold start, was -53 and I forgot to plug it in. it went into safe mode and I want to know how much this is going to cost me?
Nicely done
Cheers man
Great video..good job on diagnostic.where do you get that schematic on your computer?
Thanks for the break down
You saved me exactly my problem
Nice job Will
Ive been having engine fail safe mode and the 2 shops I went to wanted to flush the oil and clean it. The other shop wanted to replace catalytic converter, I really appreciate any help.
Excelente amigo buenas ideas
Hi great vid. Is there an actual fuse for the tps?
