Ford - Focus :: 2004 - Check Engine Light Came On
May 30, 2011
My 2004 Focus passed its emissions test in Maryland in the late fall last year. Shortly thereafter, the check engine light came on. My mechanic put it on the computer and said it needed a new catalytic converter. It only had 86,000 miles on it. I watched and waited for a few months and had the fuel filter changed during a routine oil change. A couple of days after the fuel filter was replaced the check engine light went off and stayed off for 4 months, but it came back on a couple of days ago. I have been watching the mileage carefully and it has been steady at about 26 MPG for years.

Ok I just bought a used 2003 Ford Focus from a dealership which I am financing and after the second day driving the check engine light came on. Once I saw that I took it back to the dealer and he told me the sensor was very sensitive and because I didn't close the gas tank tightly the light came on. I didn't feel satisfied with this answer so I took the car for a diagnostic. They informed me that the car had a gasket leak. I then took the car back to the dealership and told them what I had been informed and the mechanic told me that it wasn't a big deal, nothing for me to worry about. Now I don't know much about cars and I have been doing a little research of my own and a gasket leak seems to be a big problem.

I have a 2001 Ford Focus ZX3 (2D Hatchback) that has been randomly stalling since we bought it. There is no engine light, the dealership couldn't get it to stall and just gave it back. Another garage got it to stall and thought it might be the "idle-oxygen sensor" (not sure if I'm remembering the name correctly), but that didn't stop it from stalling either.
My wife is ready to dump it, but even spending a couple thousand a year on repairs is less than the grand total of a year's payments on a new car, insurance, etc. But it would be nice to fix it.

Ford Focus Station Wagon 2006 - Seems to have electrical problem. Warning lights for check engine and ABS come on randomly. Also when car is parked and temperature is low, Clock time is lost and radio stations are lost. Is there some type of grounding issue?

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 have a 2004 Ford Focus. I had the battery replaced in May. Two months ago, the battery light came on for 10 minutes than went off. A week later the dash lights dimmed and then rebrightened. Talking with people they thought the alternator was the issue. I had it replaced three weeks ago. I got it back from the mechanic and it worked for two days.
On day 3 it would click and the dash lights would flash but it would not crank. Mechanic jumped it and brought it to the shop and found nothing. Two days later the same problem. Took to another mechanic and they found the radio was draining power so they unplugged the fuse. Again, it worked for two days, then the same problem. They have had it for a week and have no clue what is wrong.

Recently the temp sensor on my car goes all the way to H and then the light comes on saying I need coolant. It only seems to happen when I have the heat and/or defrost on -- if I turn the heat off the temp goes back to normal within a minute or so. (no problem using rear defrost)
First time it happened I pulled over, checked coolant level and added a little. The next time it happened I looked under the hood the next morning and coolant level was just fine.
Happens more often when I'm driving around town than on highway. Usually within about 5 minutes of driving in the morning the engine temp is all the way to H.

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

This car has been giving me quite a bit of trouble lately. 04 Ford Taurus SES, about 97,000 miles on it. Just last weekend, it broke down on the highway. Found out the torque converter failed and needed to be replaced. I was suspecting that something was wrong with the transmission for a while now, because it would stutter sometimes when accelerating, and sometimes start shaking in the front when I turned it on. (It still stutters after having the torque converter replaced.)
Well now, a day after shelling out quite a bit of money to the dealer for this torque converter, the check engine light is on. I went to Autozone to check the codes, and they found P0300, P0305 (cylinder misfire) and P0316 ("crank sensor condition"). Is it possible the transmission is failing?? I found a bunch of complaints online about the transmission failing on the 04 Taurus. I'm trying to avoid more expensive repairs, but I don't want the car to break down on me again....
Also, a couple months ago, the check engine light went on a few times, but always went off within a day or two. Never did get it checked out because it didn't stay on long enough.

I own a 2004 Ford Escape, auto, v6. I bought the car in 2007 and have had trouble with my check engine light ever since. It is usually on, but will turn off shortly after I wash it (then back on a week or so later). When mechanics test for the code, they say that my catalytic convertor needs to be replaced. In addition to the on/off strange behavior, I have been driving this car for 4 years now with no major mechanical trouble that I can only assume would result from not replacing the CC. This would be very expensive repair, one I am not interested in doing if this is possibly just an electrical problem. I am ready to get this problem solved and start driving check engine light free.

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 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 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.

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...
