Ford Excursion :: Check Engine Light Illuminated For Codes P0171 And P0174
Coming home from spring break towing the TT, the Check Engine light illuminates. Seems to be sputtering at idle, but otherwise OK, so we continued home.
Scanner lists the P0171 and P0174 codes. Ok, where to begin? based on internet info, started by cleaning the MAF sensor and throttle body. When I pulled apart the intake, noticed that the grommet which feeds the MAF in the air intake had become separated letting air bypass the MAF. Hence the reason for the codes.
If you get these codes, check the grommet for the wires feeding the MAF in the air intake to make sure it hasn't become separated from the intake. No more codes.
Sonata NF (2006-10) :: Check Engine Light Came On Then Went Off?
I unplugged the battery and left it over night. Started her up and there was no check engine light. I'm thinking it could be because of the CAI I have installed? Took it to autozone and he said it showing no codes.

I just changed out the spark plugs in my 06 Sonata and now the check engine light is on. The car runs fine but I can't find out why the light is on. Is there some reset switch?
View 7 RepliesFord F-150 - 1997-2003 :: 1999 - Check Engine Light Codes P0171 And P0174 Lean On Bank 1 / 2
I have a 99 f150 with the 4.2l v6 with a 5 speed 173000 miles. I picked it up not to long ago. When I first got it it had both the P0171 & P0174 lean on bank 1&2 it was also siting for a while. I replaced the fuel filter which was filled with black fuel, also changed the PCV valve, cleaned the MAF sensor, and changed the oil. I cleared the code, drove it for a little bit and the light came back on after 20 miles.
I then proceeded to replace the upper and lower intake manifold gaskets. Upon doing that i noticed that i was missing one of the linkages for the IMRC. I went to the junkyard and pulled off another linkage rod off the same motor. ordered new plastic clips, put the IMRC on cleaned everything up and began putting it back together. I also cleaned the Injectors while i had them out as well and put in new spark plugs and wires.
Put everything back together. code was cleared since the battery was disconnected. drove it and then the engine light came back on again. this time it was only the p0174. so i then both the upstream and downstream O2 sensors on bank 2, reset the code and it came back on again. I'm lost.
Sonata NF (2006-10) :: No Reverse / Check Engine Light Came On
My 06 Sonata 120k 3.3L Does not go into reverse. (automatic) Took it for a short (1/4 mile) ride. Shifted fine at first then check engine light came on and it seems to be stuck in 3rd? What this may be, I don't want to get ripped off on a repair I don't need.
View 4 RepliesSonata NF (2006-10) :: HIDs Cause Check Engine Light
I recently installed HID lights in both the low beam and fog/driving lights on my 2008 Sonata Limited. I used relay wiring kits so the HID's pull power straight from the battery. When I turn on the HID's after starting the car, the engine stalls and throws a check engine light with codes P0698 & P2110. Took the car to the dealer and all they really did was verify the codes and clear them claiming it was fixed...NOT!!
If I restart the engine 2-3 times with the HID's off, the check engine light clears itself and if I rev the engine RPM's while turning on the HID's then it's no problem. The HID's otherwise work great..and again the only power they pull from the car's electrical wiring is the signal from the headlight switch wiring that trips the relay to turn the HID's on!! The HID relay wiring kits have inline 20amp fuses between the battery and relays and they are fine, so the HID's can't be pulling that much current.
Sonata NF (2006-10) :: Check Engine Light Is On - Car Won't Accelerate
I have a 2007 Sonata Platinum Edition with a V6. I changed the battery in December 2015 and the car has been sitting since then waiting for my niece to buy it. I haven't driven it since the battery install until today. The problem is although the car started easily I noticed the Check Engine Lite is now on and so is the ESC Off light. No matter what I do the ESC on off button it still says ESC Off. So I thought I'd take it for a ride only to find out that the engine won't run much faster than an idle. Floor the gas pedal in drive or reverse and nothing happens except the car moves very slowly. Just a little faster than it would if you put your car in gear but didn't give it any gas.
View 3 RepliesSonata NF (2006-10) :: Oil Pressure Light Along With Check Engine Came On
so I bought a 2008 Sonata with 70K miles about a month ago...
about a week ago, I noticed the oil pressure light was not going off immediately, it would stay on for like 5-10 seconds after the engine would start, usually it would fade away, sometimes flicker..
anyway, the time it stayed on and took to turn off got progressively longer every day (as long as 30-45 seconds) but it eventually goes away... well today the check engine light came on, and now the oil pressure light will flicker occasionally, and seems to do so based on actual pressure, not like a loose wire or something...
whats weird is if i'm acclerating, or maintaining steady RPMS, there is no light, but if i let off the gas, it will come on real quick, like a fraction of a second and go away, but when the car shifts (the same type of RPM drop) it doesn't happen...
anyway, I'm pretty chapped about it as I just got the car less than a month ago and bought it as is, but now i'm freaking out..
oh also the car doesn't leak, the oil change is less than 1K miles old and the oil is showing full on dipstick.
Sonata NF (2006-10) :: Check Engine Light With 8 Different Codes Just Came On
The light just came on in my 06 Sonata 3.3L, showing many codes... P0171B, P0172B, P2187, P2188, P0174B, P0175B, P2189, and P2190. All of these just came on at once, within the last hour. Everything that is stated is regarding Too Lean or Too Rich on Bank's 1 & 2. Where to start on this...
View 9 RepliesFord Super Duty (1999-2016) :: Running Rough - Check Engine Light Came On And Got Codes P0171 And P0174
My 1999 F350 SD V10 that would crank but not start. I ended up checking numerous things because before it decided to truly stop running, it would run rough for a time and then be fine. The check Engine Light came on and I got the codes P0171 & P0174. Well, I bought MAF Cleaner and took the air cleaner housing off, disassembled it and thoroughly cleaned the sensor and replaced the air cleaner. I continued to get those same error codes, but before I could go any further, the truck totally died. It sat for nearly 2 months with the bed in the air as I had decided to lift the bed to check the fuel pump vs. drop the tank.
Fast forward a bit and I have since replaced the fuel pump and put $40 of Premium Gas along with Royal Purple Fuel Treatment in the tank because I figured things got stirred up and could use a bit of cleaning. I do not drive much, and during the first few trips, it ran perfectly. Then today, it started again with the rough running and trying to die if I let it idle. If I pushed on the gas, it would completely smooth out. If this were a carbureted engine, I would think the low idle was set too low, but since it is not, I am guessing it is one or more of the sensor/s that is/are causing the issue.
I am disabled and can’t play parts swap until I hit on the right part, so I was hoping that I might get some guidance here to narrow things down to the most probably causes so that I won’t go broke changing things until I hit the “right one”. The truck has 153,000 miles on it and I had bought it from a retired couple who used it to pull their 5th wheel travel trailer, so it had mostly highway miles on it. It was immaculate when I bought it and ran perfectly, needing only normal maintenance (oil changes, etc.) over the past 12 years that I have owned it. In those 12 years, I have put about 60,000 miles on it.
Sonata NF (2006-10) :: Engine Knock And Check Engine Light Came On
I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.
It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.
I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?
Sonata NF (2006-10) :: Changed Battery, Now Check Engine Light On
2009 2.4 Sonata. Replaced the battery. Engine light came on after battery replacement. Engine code P0106 (MAP sensor or vacuum leak). Car drove fine before and after the battery replacement. Engine light after replacing battery?
View 2 RepliesSonata NF (2006-10) :: Check Engine Light Flashing / Stall
Earlier today i left my car idling for a couple of minutes and when i got back in and started to drive the car was vibrating, almost as if it was going to stall and the check engine light was flashing. drove a bit and stopped, started the car and now the check engine light stays on constantly. I have had the light come on (and remain on) a few times in the last while but it is usually solved by tightening the gas cap. it always seems to happen when i am low on gas (100 mile range-ish) Someone suggested maybe i had dirty gas in the car and needed stabilizer. My boyfriend said its a "misfire" and to change the spark plugs.
View 9 RepliesSonata NF (2006-10) :: Check Engine Light Comes On When Accelerate Quickly
My Hyundai Sonata has been the dealer twice so far and the problem hasn't been fixed yet. Once in a while when I accelerate quickly the check engine light comes on and the esc light comes on and the car goes into a limp power mode or fail safe mode and the engine won't rev above 2000 rpm until I turn the car off and back on again.
Both times I have had the car to the dealer the Scan Code "P2138 Throttle Position Sense P2106 Elect Control forced limit power" Were found. They cleared the code drove car and it did not return.
This has now happened about 5 times, in the last year and each time after switching off the car it runs fine, and after about 5 starts the check engine light goes off.
Well this just happened again yesterday (just as I was about to blow off some kid in a Ford Taurus from a stop light) So I called my dealer (who has been very good thus far with my car) and told them about the problem happening again and that this time I want this sensor replaced, and not having the code cleared.
Sonata NF (2006-10) :: Dead Battery And Check Engine Light
2nd battery in 2010 Sonata 4-cyl died on my wife last night. Got a new battery today and put it in. (Couldn't move car even to push as there wasn't enough juice left to get transmission out of Park). Started right up after battery replacement and ran engine at idle for probably a half hour. Engine seemed to run a little funny. Lost RPM's and sounded like it might die a couple of times, but it stayed running. Now the dreaded check engine light is on. I've had a couple of stop-starts since it began, so I'm not sure it's going to go away. Car seems to be running fine now. Is there a connection between the battery going dead (so dead I lost radio presets and trip odometer readings) and something fouling up the check engine system?
View 2 RepliesSonata NF (2006-10) :: New Battery Installed Now Check Engine Light Is On
2009 Sonata 4 cyl with 40,000 miles.
My car was slow to start last night. This morning took it to Autozone and they checked the battery, which was bad. Got the new battery installed and drove about a mile then turned off engine. Upon restarting engine, Check Engine Light came on.
The timing is such that it seems the CEL is because of the battery. How to handle? My car has otherwise run perfectly in its first 40,000 miles of life. Only other relevant detail is that the presets on my radio kept resetting, I figured this may be because of low battery power.
Sonata NF (2006-10) :: 2007 - Check Engine Light Flashing
I have had this issue on and off for a while. happened about 2 years ago just after i bought the car, and just started last week again.
The car will be running fine, then will start to buck while accelerating, shortly after the check engine light will start flashing and the car runs like it is on 1 cylinder. shut of and start again, light remains on( not flashing), car runs smoother, but does not accelerate like it should.
took it to autozone, they said it was giving the code for random mis-fire, and O2 sensor.
2 years ago the dealer said it was loose coils, and they fixed the problem, all the coils feel tight this time.

View 9 RepliesSonata NF (2006-10) :: Check Engine Light Came On With P0449 Code
I have a 2009 Sonata (base model) with about 60,400 miles (just out of warranty). My check engine light came on, I drove for about 25 miles or so and it went away. I still took it to a shop to get the code reading, it came back as "P0449 - EVAP Vent Valve Solenoid Circuit". Guy at the shop told me I can continue to drive without any issues but I should get it checked with a dealer. The engine check light is not on anymore.
I took it the dealer and they told me they will charge me $145 to run another diagnostic (they can not use the one I have from Auto Zone). And then on top of that, whatever they need to do, they will charge for that. And since I am out of warranty (barely) I will have to pay out of my pocket.
