Ford F-150 (2004-2008) :: Lost Power And Check Engine Light When Putting Pedal Down?
Jan 19, 2016
I went for a drive in my new truck and hadn't put the pedal down until now. its really cold here (5f, or -15c). Anyways so i waited for the engine to get warm and then i put my foot down until i got to about 100km (60 mph). Everything was fine, I was on a gravel road so i turned around and did it again, this time i totally lost power once i hit around 60kmh. the check engine light flashed a few times, i tried again, same thing, this time the check engine light came on and stayed on.
I eased off the gas a bit, then came to a full stop a little ways down the road. I tried again and this time i had full power, though i didn't take it to 100kms because there were icy patches all over the road and the truck went a little sidways. The check engine light was off, and i tried one more time after that and got up to 100 and everything was fine and the check engine light never came back.
I'm worried, my first real truck here, what happened?? Also when i stopped the truck i had a listen to the engine, everything seemed normal, but I've noticed before there seems to be a clacking sound almost, not sure if this is normal with a 5.4? I had a 2.2 litre sonoma before this so I'm new to all this.

I loaned my car to a friend for 2 days. While driving, she allowed it to run out of gas. The check engine light came on as soon as gas was put into the tank and has never gone off. I now need to get inspected, but afraid it will not pass. Someone said to put "Garanteed To Pass" in the gas tank. I have never had any problems with this car. I am the original owner, and I keep the oil changed and the filter clean. The car runs perfectly with 120K miles! What should I do?

I have a 2011 f250 with the 6.2 liter gas engine. Lost power and the check engine light came on. I pulled the codes and it is a camshaft position sensor and 4 other codes for misfire on all cylinder for that bank. I can't find any info on where the sensor is located or how to replace it.

I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)
No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... At about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.
I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...

I have an 05 F150. Last week engine started running rough, check light was flashing. Engine lost power and got more erratic. Had it towed to Ford dealer, Dickson TN. Dealer says "#2 injector has suck open and flooded the Cylinder and bent the C-Rod." Ok have put in another 5.4(not at Dealership) hummm new engine runs the same as the one that came out. Had A different Dealer check this engine they tell me the right bank is not making compression cam has jumped time.

I have a 2006 Toyota Solara V-6. I was driving down the street with no indication of what was about to happen. All of the sudden my check engine light came on and the car lost all power. I had the car towed home and had a mechanic look at it he put his scanner on it and I'm not sure what codes if any came up but he decided it was the ECM so he found a used one with a warranty and ordered it, he put it in and it did the same thing it turns over but wont start. What could it be ?

I have a 2014 passat. The battery went dead and I had someone come out and recharge it and it did fine. However, the engine light is still on. I have left the car running for approximately 20 minutes in an effort to charge the battery, which it has, but the light that is shaped like an engine is still on. Does this need to go back to the dealership to fix?

I have a 2002 F250 4x4 Powerstroke with Automatic. I have been having off and on issues for months with the throttle going dead. This only happens when I start it, if it works when started it will continue working until a different start session.
I have replaced the pedal several times before learning how to check its output with a meter and am quite sure that is not my issue at this time. However, when the pedal is depressed the check engine light lites up and nothing happens.
I am thinking it must be the computer itself, but was told there is another sensor or module under the hood that could cause the issue also which is several hundred dollars to replace as would be the computer.
Is there a way to test the computer, and what is this other module/sensor if it exists that could be the issue? Unhooking and rehooking the battery to reset the computer is no longer working to buy me a few more weeks, is there a simple way to reset the computer to try?
I love this truck when the throttle works but I am getting tired of paying on a truck while having to borrow a vehicle to drive to work.

I have a 2005 with 206,000 miles and the check engine light came on. The code reads "pedal position" but local mechanics are not knowledgeable to deal with electronics. The check engine light has been sporadic off and on so is this serious?

I have a 2006 f 150 5.4 ... Changed out all spark plugs, Never had a CEL since new. I disconnected the Battery, Removed the PCM (clearance problem)replaced the plugs, (of course broke 1) replaced PCM, hooked up battery. Truck runs smooth as can be. CEL is now on steady. Could this have happened because of PCM removal? Heard about flashing PCM? Or should i bring it to Auto zone for code reading?

I've got a check engine light on but the truck runs fine. I checked the fluid levels everything seemed normal. Any special trick that I could try to reset this check engine light myself? It's got the 4.6 L, Stock no mods, been keeping the regular service intervals at the dealership.

I have a 2005 f-150 with the 5.4 engine. Bought it new and now it has 107,000 miles on it. Recently,it would have a shudder at 65 or 75 mph then the passing gear would kick on and it worked perfectly. The warning check engine light came on,then,when it acted up it would flash intermittently. Took it in to the dealership and put it on the diagnosis machine. Said cylinders 2,3, and seven were not steady etc?? So,after he took it out and drove it he said those particular cylinder walls were scored. I put in a K-N air filter at about 50,000 miles,and he said that they do not seal properly and dust got by the filter into the intake and got into the engine and did this damage. One think he found was a bad coil on one cylinder and replaced it. And just as he said,when I got on the road home I romped on it and it cut out and the intermittent signal showed again! He said that that would happen and it did.

So the check engine light came up on my truck and I scanned it to find P0021 which is Intake camshaft over advance or VCT solenoid stuck open. I really doubt my truck skipped timing and all the research I've found had it linked with other codes requiring cam phasers. The truck is a 2008 F150XL with the 5.4 Triton with 90k on it

I was driving when the truck made a terrible noise and while pulling over the check engine light went on as well as low oil pressure. I turned off truck and checked but no evidence of any leakage at all. Checked oil stick and was dry. Let sit for an hour and checked oil stick to find about 1/2" showing. Added oil to find that now it was overfull, drained oil back and stick showed proper level. Attempted to drive and it was fine until I came to a stop wherein it would stall with "low oil pressure" showing and check engine light on. Brought to shop and they said engine is very gunked up, they said they could try oil flush but probably will not work. They most likely will have to remove the valve cover and such to physically look at engine and take it from there... (I have always used type of oil stated on the cap, used synthetic and changed every 5-7k miles - showed diagnostic codes p0011, p0340, p0345 and p0021).

I bought 04 Lariat (5.4 3v around 100k miles, Roush Off Road side exit exhaust, DWV intake mod, SCT 3015 tuner).
The truck has had a miss on and off for around a month I've changed plugs and tested all the coils. Which cured the problem for around a week, the FPDM had some white stuff on back and soft spot but not ate through. The only Check Engine Lights have been bank 1 to lean (which went away as soon as it came. But yesterday and today I've got bank 2 to lean.
Below is a quick data log pull... The misses is about ready to ship her out if she don't straighten up..

I have a 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...

I have a 2006 F-150 with the 5.4L. I got the check engine light and the computer says catalyst deficiency bank 2. So I assume the passenger side converter is blocked. Is there anyway to either take out the cat and replace with a piece of straight pipe and bypass the o2 sensors or take the cat out of the housing and put the housing in and then bypass the o2 sensors.

Ive got an 02 2wd escape with the v6. Its been an excellent truck until here recently. The wife has had a weird problem twice now, that I have been unable to reproduce. She says the check engine light and low oil light come on and she loses power steering. Shutting it off and restarting fixes the issue.
Took a 400 mile road trip with it last weekend and never had an issue. Only thing I noticed , the readiness meters never went ready. Even after that trip, It still shows a systems not ready code.
Tonight the wife had the issue again. Shutdown and restart fixed it. Battery cables are clean and tight, several grounds were freshly cleaned a couple months ago.

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%
[Code].....
