Ford F-150 (2004-2008) :: Emissions Light Blinking At Certain Speeds
Dec 13, 2013
Having problems with a blinking emissions light at certain speeds? I have a 2006 F150 with the 5.4L engine with 132,000 miles on it and have had a problem with the emissions light coming on when I reach a speed of 80 mph. The pickup will drive fine up unto this speed but when it reaches 78-82 mph the pickup will start shake/rattle and the emissions light will blink on and off repeatedly until you reduce your speed to around 60 mph and then the light will turn off completely.
We took the pickup into the local Ford dealer for them to look at it. After they took a look they couldn't pull a code because there is no light that comes on until the higher speed. They told me that this was due to a bad tank of gas and this happens to prevent damage to the catalytic converter. They said it would be better once that fuel burned off. Well two full tank fills later the same problem persists. Just wondering, what course of action they took to fix it.

A couple of days ago my emissions light came on in my truck and the P0054 is the code I get when I scan it. Did a little research online and it looks like it could possibly be a 02 sensor issue. Truck seems to be running fine.. I have a 06 F150 with a 5.4L.....

My 2005 STX 4x4 was running fine until yesterday, then on my way home I lost all forward power. The odometer displayed TRANS FAULT and the O/D OFF light was blinking. Limped home.... Today I checked the fluid level and it was a little high, so I ciphoned some out. I read a lot of posts about the same problem which lead me to my local autozone to have them put a code reader on it. Unlike all of the other posts, NO codes came up.
According to the scanner, my truck is fine. I was hoping to get some kind of "P" code to target the problem, but no such luck. I checked all the fuses and they are fine. What should I do now? I don't really want to take it to the dealer, fearing that they will automatically say I need a new tranny without checking everything else first.

I've got a 2004 6.8L Excursion (about 124k mileage). Was gassed up yesterday, today the emissions light popped on. I checked the fuel cap and it was on tight. Any other easy things to check before I head down to Advanced Auto to see if they can pop it on the diagnostic machine?

So here's the deal: My 2000 F250 has began to have the overdrive light blink when I am traveling at low speeds <40mph and it is accompanied by strange shifting (lower gear for a longer period of time). As soon as I get up to highway speeds the blinking stops and goes back to normal operation. But as soon as I go back to low speeds it happens again. When I put the truck in to park when it has the light blinking it revs it self to about 1200rpms then goes back to normal idle. This truck has 228k miles and is on the original transmission.

On my 2006 Ford F150 2WD, v6 automatic, the overdrive dash lamp is blinking, I get a engine light and the code I get is a P0743. That indicates the solenoid or wiring is bad, but everything works just fine. The transmission is running fine, clear fluid - no odor. The overdrive works and the truck shifts like new. When I start, the "OD-OFF" light immediately starts blinking and never changes. I can activate the OD normally and it doesn't effect the blinking light.
Where to start? I suspect that since all is functioning well, the issue is with the signal to the ecm? By the way, I can clear the code so that the engine light goes off, but the "OD-OFF" light remains blinking.

I recently had u joints and left front wheel hub assembly replaced at a local mechanic. Ever since I have a vibration between 40-45 and 52-62, the vibration can be felt in the steering wheel, the seat and the floor. The mechanic claims I need a new driveshaft as some of the counter weights were starting to rust. I indexed and removed the drive shaft and had it rebalanced at a local machine shop. This did not solve the vibration problem. There is also a transmission leak starting from the extension housing. How I can start to trouble shoot the problem. 04 F150..

I have had a 2004 Extended Cab F150 5.4L for a few months now. It just started vibrating at speeds between 15 and 30mph on accelerating or deceleration. Doesn't matter if I'm turning or going straight, just those speeds. It's fine otherwise. I put it in gear and held the brake down and brought the rpms up to 3000 to see if it would shake with a load, thinking a possible misfire, but nothing abnormal.
It's an automatic transmission. I started off in 1 and 2 and it seems to lack power until it shifts to 3rd gear - which is about 30mph. It also seems to lack power in reverse ... no slipping, but seems to have to give a lot of gas in order to go over the slightest incline backing up.

I have a 2007 F150 (2wd) with 80k. My truck recently was vibrating under braking so i took it to my mechanic to have the brakes fixed. All the rotors needed to be replaced. In doing so, the front rotors were changed out with the kit that converts the front rotor/bearing assembly into two separate pieces to cut down on maintenance costs in the future. With this being said, after getting this work done, the truck didn't vibrate anymore... that is until i got it out on the highway. Now the truck vibrates from about 45-50 and 70-80 pretty bad. The steering wheel shakes back and forth too. I have gotten the tires balanced in hopes to fix this problem which it didnt. What could this problem be?

06' 5.4 screw 100K... At 55mph my truck just stopped running, I pulled over to the side of the road and after two trys the truck restarted but ran rough. Auto Zone pulled a code that said replace the throttle position sensor, I did and the same thing happened again two weeks later just as before.

PCS blinking yellow light? I know what it is for but just got the car (2011 ISF) on Saturday and no PCS light. Drove it for about 10 minutes the first day I got it and then couldn't drive it again until today. Today = PCS light.
I was investigating wiring yesterday in the sunroof area for possibly hooking up a radar detector, which I didn't do yet. I replaced the car battery the day before. Drove it around today for really the first time and the PCS light remains.

We have a 2006 F150 w/new engine, new everything but transmission and cat. converter. When driving in warm weather with the AC on and at low speeds or idle the engine will knock and want to cut out but you rev and turn off the AC and it stops. Only with AC on. We replaced fuel filter, fan throttle took to dealer and updated the software which it stopped for 3 days and started again today. Could it have to do with AC compressor or low refrigerant?

Sunday I had a new set of tires put on my Civic. They told me that one of the four Tire Pressure Monitoring System sensors was bad and that they'd have to order me a new one. I drove home that day with the TPMS light on, which was expected.
This morning I went back to the shop and they replaced the bad sensor. However, after resetting, and doing whatever else it is they did with the handheld computer thing a half-dozen times, the Low Tire Pressure Indicator light is not only on, but blinking. (The TPMS light is off). They drove it around, they checked it with their computer thing again, they plugged in the handheld thing to reset it, went around and did something at each of the tire stems multiple times, but no matter what they did, the light wouldn't (and won't) stop blinking.
"If it doesn't stop on its own, you might have to bring it to a Honda Dealer."
Seriously?
I used to have an old Aurora that would turn on the engine light every time a reading went slightly out of whack, and after so many ignition key turns (on and off) the light would turn off on its own. Is that the case here? Or is this light going to blink forever until I go to the Honda Dealer?

Driving around town it doesn't happen too often. Like if I am starting from a stop it feels fine but when going up a hill or passing on the highway it bucks and shakes and doesn't want to go over 3000 rpm. Also, the check engine light is on and it flashes when it's really bad. I took apart the intake and didn't see anything weird. I am about to take it in to see what the code says because it's been getting worse.

I have a 2007 F150 King Ranch Super Crew 5.4 3v and it makes a ticking sound. I have read about the VCT solenoids and the phasers. My issue is that the ticking noise can be heard at Highway speeds. At it seems to be quicker as the engine speed increase. Not sure what to think. No rough idle. What could this be.

On my 07' I bought it home mid AUG. It has been getting much worse to a point there is a rear driveline vibration at all speeds above 40 and up to 70. I used to change intensity whether you are on or off the gas, and would almost vanish if in neutral. However now it is all the time.
I cannot feel any play on the u-joints, the yoke has a little play in the xfer case but is is normal like on most other trucks I have owned, and the pinion flange is nice and tight. Could this be **tight** ujoints or the driveshaft itself? It looks rusty, but there are no dents on it.

First, details about my truck. 2007 F150 SuperCrew, 2wd, 5.4, 203,xxx miles on it, leveled with Hell Bent Steel 2.5" kit last year, has been aligned professionally since then, tires are good and balanced.
The issue I have is a vibration, kind of the same feeling when driving on a road surface that has had the top level of asphalt removed before it's resurfaced. It's mostly noticable at highway speeds. Its not a violent type vibration, but you can feel it. There is also a sound, similar to tires with a deep off road type tread.
The sound and vibration more noticeable when making lane changes or when wheel turned towards left, at highway speeds, not as much to the right. I've checked front wheel bearings, they are good, zero play, no loose suspension parts, u-joints are good, no leaks anywhere.
Since it makes the noise and vibration a bit more when moving wheel, could it be a power steering pump? The pump is the original.
