Santa FE SM (2001-06) :: ECU Fault P1707 And P0302 - Car Started To Shake And CEL Came On
Feb 9, 2014
I have a 2003 3.5 Santa Fe. Last week while my wife was on the way to work, and still in the neighborhood, she said the car started to shake and the CEL came on.
I checked and got these two codes:
Pending Fault Log
------------------
P1707: Unknown code
P0302: Cylinder 2 Misfire Detected
I replaced the spark plugs in cylinders 2, 4, and 6. Not 1, 3, 5 yet since those are harder to get to.
I drove the car about 10 miles and it seemed to operate fine. The CEL stayed off. However, my scanner still says Pending P1707. The scanner showed no errors when I first started up the car, but I decided to do it again about 5 miles in that is when it showed the error.
I've done some searching but the responses for this code are inconsistent. What this error is about?

I just purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?

I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.

I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

The best that I can describe what it feels like is at around 30 to 40 mph it shakes like your going over the side shoulder little pumps with both wheels. Only at those speeds... I all ready changed struts, tires, rack in pinion, upper and lower ball joints and tie rods. I have not change the tie rods that go up and down from struts to spindle its like 6" long or so can that be it? Or CV shaft?...

I have a 2005 crdi diesel santa fe that i have a strange problem with it starts up first time no problem in the mornings and can drive all day long. However if i switch it off and leave it sit for about a half hour no way will it start again until it cools off. It will start though with a push start instantly!
I got only one fault code P0340 cam shaft sensor fault, i replaces sensor and made no difference. Is this a common fault???

I have a 2000 f150 with 5.4 Triton with 165k miles. I did invest in a code reader. It started missing and code P0302 came up along with P0171. Put new coil on #2 and truck ran fine for a few days. Then it started to run rough again. Shaking, Idle rough, no power and CEL came on again. This time code P0171. I changed out fuel filter to no avail. My next step was to start looking for vacuum leaks. As I'm searching, All I am finding is trucks with this problem also get P0174 code. My question is since I am only getting lean on one bank does that pretty much eliminate things like MAF or the famous elbow vacuum leak and make something that only affects one bank like an O2 sensor on CAT more likely?

2002 santafe 4x4 v6. about week earlier I had a cel for temp sensor voltage high. so I replaced it. then... my power steering cooling loop by radiator started to leak from corrosion and for some reason my coolant gauge was reading about a needle with from the red. (maybe from getting ps fluid on it? idk) so I went to investigate why it was leaking and I thought the cooling loop pluged into a cooler on radiator so I removed my lower front engine mound and motor mount by the timing belt so I could raise engine up a2" to get a better look. when I saw it was just a loop and that was my leak I ordered replacement. It came in I swapped it out. Pretty easy . Decided to do a radiator flush and replace thermostat. Why I was at it. I drained radiator and took the old thermostat out. was gonna leave it out for the flush to cycle better. When I started it up it was idling around 4k rpms. I figured it might be because of thermostat so I put the new one in.
Started it up and same thing.... I check all the vac lines I could find all were tight. I unplugged them one at a time at throttle body/intake tube and blocked it off with my finger and it was still idling high. It also started surging. going from 2k to 4k and going back and forth. I checked the maf and it was clean as a whistle. No leaks on intake pipe. If I put my hand over maf it sucks the tube towards the throttle body. no air leaks anywhere. Took off iac valve its clean. I plugged the holes where it is on tb and started it up and no change in what its doing. also the throttle body flap is closed the hole time. Iac seems to be properly opening and closing. when I watched it after I unbolted it. I sprayed brake cleaner all over manifold to check for air leaks no change in high idle. I also took off the evap valve hose to tb and plugged it at tbody and no success.
I checked my sensor connectors and there tight and no wires are pulled out. I have yet to check cam sensor connection. (does it have a cam sensor?) I unplugged battery over night. this morning it ran at 2k rpm for two mins then surged to 4k. could it be my throttle position sensor? is there a way I can check with multi meter? Ive done a lot of research and it seems like a common problem with Hyundai but people don't leave a what fixed it post after they figure it out. they just leave the threads hanging. I hope I can figure this out.
When I get home tonight Ill plug where the brake booster vac line goes in. I looked at the hose and it was super tight and didn't seem to be leaking but maybe booster is idk. Ill also check wires to all 02 sensors. but if o2 sensor wire was broke wouldn't it throw a cel? Also no check engine light. but id did have an abs light come on the other day. was thinking maybe an abs sensor at the wheel but I am not sure. That light was on for a week before this issue started. It was never revving up until I started working on the other issues from my research I am guessing throttle position sensor. I am going to multimeter it tonight.

2004 Santa Fe AC fan has started making a rattling noise. It gets louder when the fan is turned up. How can I check it? Noise seems to be under the glove box.

Looking for some info about the 4wd system.
My car is a 2004 Hyundai Santa Fe 3.5 and several times i've seen the 4wd warning light start flashing. It happens right when i start up the engine, however if I turn the engine off and on again, the light will be off the next time it starts up.
I'm just trying to figure out what kind of problems this warning light would indicate, in case it stays on sometime. I like to plan ahead my car repairs and know what's going on with it. The car has like 190K + miles so it's getting there.
Also I try to avoid the dealer, so I was also wondering if a typical scan tool that most mechanics have could read the codes, or if would need to be done by Hyundai specifically.

2002 Sante Fe, 2.7L Belt squeals for about 10 seconds when the vehicle is first started up (engine cold) in the morning. Doesn't do it any other time until next morning. I had this problem 6 months ago and replaced the belt (OEM) and Dayco Tensioner. Now I have same issue again! What gives?

My engine in my 2002 Santa Fe 2.7 v6 has been making a ticking sound that was especially pronounced when cold starting. It would quiet down somewhat when warmed up but still a slight ticking would be there. I thought it was the hydraulic lash adjusters. I know Hyundai's service site sates that a ticking can be heard if the factory filter is not used. I tried using the factory oil filter which did not make a difference. The car had about 85,000 miles on it and I always maintained it well as well as keeping up with oil changes. I took it to the dealer to have a repair performed related to corrosion of the rear trailing arms and had the tech check the engine noise.
It was determined that the cam chains have developed slack and were slapping on the cam chain guides which prevent the cam chains from popping off in case of slack developing which was the case here. The chain guides are made of some type of plastic material and according to the tech showed significant wear. This was all covered under the powertrain warranty. For those that are not under warranty any longer and are capable of doing their own repairs this is the list of parts that was ordered by the dealer. The parts in red are the culprits. The rest are gaskets and seals. I don't think this is an easy job.

My 2003 Santa Fe makes a grumbling noise when first started, and put into drive or reverse. The noise seems to be coming from the passenger side of the engine compartment. The noise disappears when the drive train has warmed up.

2005 santa fe a/c not working. Started out barely blowing out cool air. it was cool but we were still hot in car... kept adding freon but it barely worked. One day we heard a strange winding noise and have had no a/c at all since then. Don't want to buy a whole new compressor if it could just be a switch or something.. I see there are so many a/c parts. Is there any way to tell if we need a new compressor ?

I have a 2001 Santa Fe that I am getting road ready for my son, The engine has recently started idling very high, 2500 RPM at startup. I disconnected the IAC servo and it drops right down to about 900 RPM. I replaced the IAC with a brand new one and it does the same thing at startup, 2500+ RPM. Checked vacuum hoses / tubes. I replaced 2 crack / dry vacuum hoses. Same problem for a while, then idle went down to about 1250. Started to drive it, test ride. while accelerating, seems OK as soon as I take my foot off of the gas, idle goes to 2500 - 3000 RPM until I apply brakes and then it drops back down to 1000 or so. (SOUNDS LIKE A VACUUM LEAK PROBLEM. I CANT FIND IT, IVE BEEN THROUGH 2 CANS OF CARB CLEANER AND HOURS OF REPLACING ALL VACUUM HOSES.)

My SO has a Hyundai Santa Fe - 03 2.4L with the 4 speed auto with 130500 miles.
While driving tonight, the interior lights started blinking. Which was kind of odd. Apparently when this happens, the tail lights (but not headlights) go out.
I did a quick bit of research on it and apparently there is a "bus" that goes bad and causes this. What is a "bus"? And how do I replace it? Is it something like a fuse that is getting corroded?
Also ... I think there may be something up with the a/c. When I turn on the A/C or defroster (any setting that activates the compressor), I smell a burning rubber smell in the dash. I'm not seeing the belt slip on the compressor and not hearing any slippage but there is a definite burning rubber smell. When the HVAC is on something that does not activate the AC Compressor (top vent) we do not get the smell.
Lastly, there are some transmission issues it seems. There is a shift flare between the 2-3 shift and the 3-OD shift sometimes is very firm/abrupt ... it appears to be locking the torque converter during a very hard shift.

I recently noticed while driving my Santa fe the car started to stumble.Then a little while later the check engine light came on. Pulled the code came up with p300. It's a random misfire related code.

My wife was driving this morning and she said that the car engine started to hesitate and shake a lot, engine light came on, started to bling. Called road assistance and they did a great work towing the car in less than half hour. Also noticed a rotten egg smell from the exhaust or engine.
