Ford F-150 (2009-2014) :: Engine Light Came On Intermittently?
Jan 11, 2012
I bought a certified 09 F150 Platinum a few months ago and after 4 trips to the dealership service department, I continue to have a problem with an intermittent engine light. The 1st time they replaced the o2 sensor. The second time they said a connection was loose to the sensor and repaired that. The 3rd time they replaced the PCM and catalytic converters. The 4th time, they replaced the o2 sensor again saying it was a new part that had been redesigned. When I stopped for fuel on the way home, the light came on again and has cycled on and off ever since.
When I called after the 4th time, the service guy said Ford engineers said I was getting bad fuel. I buy fuel from many places just like everyone else in Florida. I use 87 octane as recommended in the service manual mostly with 10% or less ethanol. The dealership service dept has said they have been working with Ford engineers directly but can't seem to get it fixed. The truck seems to run and perform fine. The only constant predictable thing about the engine light is that it will always turn off after the truck goes through the carwash!

Purchased certified pre owned 2009 f150 may/2010 24,000 mile. The check engine light intermittently comes and goes. It seems that its either cold temperature or related to filling the gas tank. The first time it appeared I drove 100 mile then the truck sat over the weekend and went back off when started. The second time had serviced for the check light and the dealer diagnostic pin pointed P0304, P0305, P0300 and P0316 and replaced cyl 4&5 coils.
Prior to the replacement of the coils the truck averaged 18.2 mpg since the repair the mpg dropped to 17.6 and now at 17.2mpg. Had the truck in again and the light was on when I made the appointment but went back off when I went to the dealer. They said the reset the computer. The light twice has since went on and then back off after a couple days. The only observation is that the outside temperature on both occurrences has been below freezing and that I had filled up the tank.

2010 F-150 5.4L 3V gas, 6 speed auto, 2WD.
I got a Bully Dog GT Platinum Gas with plans to purchase a tune from 5starturning. Was messing around and loaded the built in 05-10 Ford Gas tune in Bully Dog... all went well.
Take it for a drive around and next thing I see is my check engine light is on so back to the house and revert back to the factory file... again, all went well.
No such luck; still have the check engine light and the Bully Dog says there are no DTC codes. Needless to say, I'm a bit freaked out.
I have tried uninstalling the Bully Dog tune and reverting to factory file and still no luck.
I think I would feel better about it if I could just find some comment saying "this is common just unhook the battery and reset and go on your merry way".

On my Ecoboost the engine light came on today. I scanned it and the codes were 172 and 175. system too rich bank 1 and the same for bank 2. What might be causing this? Will take it to the dealer next week.

After about 5 miles from my normal place to purchase fuel, My truck bagan to run bad and the check engine light kicked on. Mileage dropped to about 8 MPG. This morning, the truck would not start and after 2 can's of dry gas, I was able to start it (barely).
I stopped at the place where I purchased fuel and at least they admitted that they has to shut down yesterday, stating they received a bad batch of fuel from their source.
Now the fun begins...How do I get the "bad gas" out of my truck?. I now have about 1/4th of a tank. I tried to run a line to siphon the gas and I can not get a line far enough into the tank.

2011 eb just turned 36k. Today on breezeway it shuddered like it swallowed a bird, and check engine light flashed on. Went to see customer left and light was off. Back on breezeway and shuddered on entrance ramp so this time I stayed into it so either there's a light that will stay on or just launch it and this time the dealer will have something to fix that they can diagnose. Check engine light is on its fine as long as I stay out of the pedal. Still have 8 months left on power train warranty but what am I looking at for a diagnose, there is definitely a problem now. What the dealership should see?

He has a 2013 F-150 XLT with the Ecoboost. He has 29,000 miles on the truck.
He is ~1,300 miles into his trip; and has about another 4,500 to go! On Friday, his check engine light came on (while towing). The next day it went back off. Yesterday, the light came back on (while not towing this time). He took the truck into a Ford Dealer in Rapid City, SD this morning. The CEL light was still on this morning when he arrived at the dealership. The dealership said the code is P0299 - Turbo Underboost.
They said they've run tests and can find nothing wrong. Naturally, he is not very happy being this far from home with 3 more weeks of vacation left and his truck acting up. Especially since the CEL light is on but the dealer can find nothing wrong. I'd be puckered-up too!
Experienced this Turbo Underboost condition? What was the cause? How can the CEL light be on but the dealership not be able to find a problem?

Truck: 2009 F-150 Lariat SCrew 5.4 4x4 with 6.5" bed
For the last few years, I've had this intermittent problem where the service engine light (wrench icon) will pop on and the truck will go into limp home mode. While it's in this mode, all of the indicators on the dash freak out. Low fuel warning will come on, temperature warning, low battery voltage, etc. Turning the truck off and back on (sometimes a couple times) is enough to get it back to normal, albeit with a check engine light that needs to be cleared. It's happened infrequent enough that I've just been dealing with it. I got the codes a couple years back, but there wasn't much information available on what the potential causes might be. The Checker Auto parts database suggested one might be related to a wheel speed sensor.
Well, this afternoon it happened again, and I was near an O'Reilly, so I took it in to pull the codes. There were 9 total in the system; 5 of which were unique:
B0025
B00D5
U0073
U0100
U0253
They didn't have any information on what was causing them. What could be causing this. I'm getting sick of having to clear the check engine light and worry about the truck falling into limp home mode when I'm at intersections.

I have a 2010 Ford F-150 4WD 4 Door. The dome light, marker lights and truck bed light will light up intermittently at night. They will stay illuminated any where from 1 minute up to 15 minutes. I thought maybe my TV remote control was activating the remote entry feature on my truck but that is not the case.

My wife came in the house the other day and told me my lights were on. When I went out to see, they were not. I chalked this up to the sun reflecting on the truck. Later I was working in the driveway and saw them come on, they stayed on for a minute then went back off. Strangest thing I have ever seen. The keys were hanging on the hook in the house. I checked the light switch and it was in Auto. I moved the switch to Off. Later that night I saw it happen again. They came on for a second them right back off. This is a 2010 F-150 4x4 Lariat. I have about 120K miles. What might be causing this or steps I can take to narrow the troubleshooting?

I have a 2009 ford f150 4.6l 3v v8 standard cab with about 53k miles on it.
Recently the check engine light came on so i went to autozone to have the codes pulled for free, it says i have a small evaporative leak.
They said may be the gas cap, but the thing is, i have a quick fill cap that came in stock with truck so the gas cap isnt even needed.
I've looked under the hood, and noticed that there is little pool of oil on top of the valley of the engine on the passenger side of the engine, could it possibly be the PCV hose that is bad and be related to the evaporative leak code? or its unrelated and i have a bad gasket for the valve cover?
It isn't affecting the performance of the engine,.. yet. I have a road trip for my work coming up very soon and i wanted to try to fix it before then.

For the last few months my truck has been throwing an intermittent check engine light due to the same code every time - P0171. The dealer has allegedly checked everything and has given me the "We have done all we can do" speech. Lead tech even suggested that since today's fuels have alcohol in them, that a check engine light would be normal. The truck has been in the shop 3 times with no success or even remote possibility of what the problem could be.
The check engine light has since gone from intermittent to constant and comes back on after 5 drive cycles after clearing with an OBD2 scanner. Also, I'm now getting a P0174 code.
Personally, I think they're trying to blow me off because I'm a few months and about 2k miles away from being out of CPO warranty.
Truck is a 2013 F150 Super crew 2wd 5.0 with about 45k miles.

I took delivery of my 2012 FX4 Eco in January and about a month or so later I began experiencing a loss of power and the check engine light would come on then go off again. This happened the first time in Houston traffic one day so I was pretty concerned needless to say but then it cleared itself shortly thereafter. However, heading back home it occurred again on the highway while I was trying to pass and she just didn't have the power. I took it to a Houston dealer late in the afternoon before I left but no codes were found and when I got it back to my local dealer it was determined the left side catalytic converter was bad and it was subsequently replaced. Well, it happened again and it's back in the shop while I am offshore so they have plenty of time to take care of it.

I have 2010 F150 King Ranch 5.4L. This truck has been giving us problems by just dying. We have haf it towed twice in two days. It does it more often when hooked up to our travel trailer. The day before yesterday we drove it 250 miles w/o the camper with no problems. Once it dies it can take an hoir or so before it starts. I just did a test and had the truck.running for a bit and then plugged the trailer wiring harness (7 pin with brake control) and truck died within a minute. A couple of times it showed that there codes. The codes were P0201 thri P208. Which is open circuit to that specific injector. When the key is turned off the codes go away.

So I have had my Platinum for a year now and really love it but there are two things that drive me nuts. First is the range of the romote start, which is the factory installed version. There is no range you pretty much have to right next to the truck for it to work so what is the point? Any way to increase the range?
Second is the audio system, I have the in-dash NAV/Sync system. I use my iPod pretty much all the time. I have it hooked up via USB. Now sometimes when I am listeng to it while driving the turn off the truck do something get back in and stert the truck the iPod does not play, I have to go to the NAV screen and push the USB icon and then it will start to play, other time I just start the truck and it play automatically. I have my system to play automatically but that is not always the case.

I purchased a new '09 f150 in '09. the truck has been fine except the dash light problem which ford has declined to correct. In low light i have no dash lights. it must be completely dark for the lights to work.
Last fall I drove a windy 2 lane secondary road at dusk without dash lights. I could not read the gauges. I did not know how fast i was traveling. This road has several tight corners.
The truck is powerful, accelerates quickly and weighs about 6,000 lbs. this is a very dangerous situation!! I have been to the dealership several times and phoned the ford customer service but to no avail!! Fords response is 'they're all like this'!!!!!!!!!!!??

My 09 F150 Platinum 4x2 used to get 15 mpg city regularly. One day while driving the wrench light popped up and i was in limp mode. I parked the truck and went to my scheduled squadron PT like a good troop is supposed to do. Anyway, finished and the truck has been fine, Ford dealer finds no issues at all with it. My gripe is now i get 12 MPG since the issue and I told them my MPG has gotten worse since it happened. What it could be?
