check engine light on can we fix it?

the flashing check engine light indicates the most serious of problems has been detected but we need to get the codes to figure out what's going on this guide can help us fix it.

My check engine light came on yesterday, and it was after I put gas in my car. I have no gas cap on my car. My oil change is up to date and I have had maintenance as I should.

Lets run the codes so we can see what is going on which will point us in the right direction to get the car fixed.

I had this problem it was the position 1 bank one oxygen sensor.

Just after fill up light comes on. All other systems normal.

The place to start is by having the diagnostic fault codes read and recorded. The people at many auto parts stores will do that for you for free. When you list the exact code number(s), we can figure out how to diagnose the cause.

My 2011 ford fusion engine light came on 4 cyl, what reasons would that be.

there are many reasons. we need the codes to help you

Have the car's computer scanned for code/s -start here

The check engine light came on and I then took the car in for an oil change as well as the transmission oil change. My check engine light went off. Not to long ago it came back on. I tried resetting it but it did not work. Just last night when coming home from work it went off. I am freaking out! How will I be able to get a code of the light keeps going on and off? Any suggestions? Anything would help. I am really frustrated.

Thank you for your help.

Hello,

We must first find out what the code is so we can fix it and clear the codes so the light will stay off.

Here is a guide to help us get started:

Hi, my son bought this car from Ford dealer, and after two weeks of having it the engine light came on. Has no issues. up to date on all maintenance, preformed by Ford. They have basically had this car more than my son has,they replaced the PCM. my son got it back on Wednesday, but as of Friday on his way to work the light came back on. As of phone call this morning, i was told they have the Ford engineers working on the issue and that they are asking mechanics to send specific data to them. Any idea on what could be causing this? I found previous questions and thought i would give this a try! Thank you..

What specific data are these engineers asking for and from what mechanics, their own. Were there any engine trouble codes retrieved from the first or second PCM?

This guide can help us get the codes so we can fix it.

Please let us know what you find. We are interested to see what it is.

Hi there, I bought a the listed above in great shape, regular maintenance taken care of 55,210 miles on it. I am due for an oil change, however the check engine light (yellow light shaped like an engine) is on steady (not blinking). now that I drive the car I want to make sure I keep it up. The car is up for an oil change and the check engine light is now illuminated (steady, not flashing) coincidence or issue I should be concerned?

Many things can cause the check engine light to come on. What to do is read the codes to identify.

Thank you so much! I just found out it was due for a 54,000 mile checkup-and now that the oil is due (hit 0% life yesterday) that it may just be the default for service. I scheduled an appointment online at a Ford dealer. Since I need the oil change anyway, I will have them run diagnostics anyway. I will get any issue codes and post. thanks for the quick response! you rock!

Glad to help. And yes, the oil life will set the light to let you know it needs changed. Let me know if you have any questions.

Take care,
Joe

Hey Joe, so are you saying that the check engine light (which almost gave me a mild heart attack) would be triggered once an oil change and/or recommended service was required?

Many of them are. Relax, if the car is still running good, I feel confident it is not anything to worry about.

Hey Joe, You were right nothing major. Had the oil changed, tires rotated and 54,000 maintenance done. The code came back that it was the EVAP control system leak and the tech believes it was the (gas cap cover). Since this is the Ford Fusion Flex Fuel hybrid it does not have a gas cap, it is a 'capless' tank. he reset it, and it did not come back on the drive home-he said if it does, take it to Ford for them to look at!

That is good news. If anything needs repaired with the EVAP system, it is part of the emissions system and falls under that warranty. I believe it is a five year/50,000 warranty with 0 deductible. I realize you are slightly over that, but if you argue with them, they will cover it.

Good luck, and we will be here if you have questions.

Joe

Thanks Joe! I bought the extended warranty (the car was used when I got it) so I bought the three year bumper to bumper extended Ford coverage (just in case!) Thanks for the piece of mind though!

You are welcome. Take care and let us know if you run into any trouble.

I bought a 2010 in great shape in PA back in February with about 63,000 miles. I love it. Worked great. We moved here to San Antonio, TX early June, the "check fuel fill inlet" warning came on. I found out how to fix that. cap-less fuel. Reset the OBD. That seemed to fix it. But now I have a check engine light. In the three months I had it in PA I did not have anything go wrong! I make a 1,600 mile trek and now I am having small issues. Still runs smooth, nothing rough. Love the car!

2009 Ford Fusion; Service Engine Soon light is on; was serviced at 30,000 miles and now is at 31, 400 miles.

My engine light came on so I took it to Autozone had them do the engine check and it said the transmission speed sensor was misfiring so I had it replaced but the engine light is still on along with the wrench light. Also the car is okay to drive around town but I cant drive it on the freeway cause I cant take it past 55-60 cause the car will begin to lose power which is bad cause I work out of town. So would you happen to know what would be causing this?

It's nice the auto parts guys will read codes for you but they're in the business of selling parts. Diagnostic fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. About half the time a sensor referenced in the code is actually bad but half the time the sensor is not the problem. There can be breaks in a wire, corroded connector pins, a wire rubbed through and grounded out on an engine part.

I bought this car back in March. I haven’t been able to drive it for a month due to this weird problem it has. The transmission light is on, and when try to get up to speed, it gets stuck in first shift, and the check engine light comes on.

Hello,

This sounds like the input shaft speed sensor is out. To be sure here is a guide to get the codes to confirm the failure:

I have a 2006 ford fusion and it has about 55,000 miles. just recently i was driving and the engine light came on and seconds after that another light came on and it looks like a ranch thats when the car started shaking and slowing down and then came to a complete stop. I cut it off and started it again and 15min later it did it again, please help me figure out this problem PLEASE

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.

WE had to replace our battery and when we reconnected and started our car the check engine light has come on is this just becasue of the battery

Scan for codes and keep a record of the codes. Then clear the codes and drive the vehicle. When replacing the battery on some cars, everything resets and it has to relearn all the parameters. Driving the car fixes this issue. If you don't have any drivability problems, I would suspect that they are false codes and most likely won't come back once cleared.

hi my name is cazza and i hav a ford fusion 3 and my managment light keeps coming on and of i hav had it fixed and it came back on but goes off again and my petrol gauge somtimes moves from one line to half a line so i dnt realy know wewr i am with my petrol. i hav had th problem fixed thy said it was a sensor on the exsors tha makes the managment light come one i thought the problem was fixed only to find that the light comes back on but goes off and was wondering if its anything to do with the petrol gauge because that goes up and down as if i have a dip in the petrol tank please please help me

Have the fuel pressure tested. Then clamp off the fuel return line from the regulator and test again. I'm guessing that the sensor you had replaced was on the exhaust. That would be the oxygen sensor. Try cleaning the MAF/MAP sensor. MAF sensor will be on the air intake horn tubing; MAP sensor will be on the intake manifold.
