This little engine runs very hot. To make matters worst the radiator fan comes on high on the gauge temperature reading unlike other cars I have had in the past. What else to do to run the engine cooler without affecting fuel economy? I wish there was a way to make the radiator fan come on at a lower temperature.
View 5 RepliesI have a 2002 Santa Fe V6. I'm getting the codes p1529, p0755, p0760, & p0765.
The car can start up & go, only for a short time. Engine will keep running, car won't move.
Kill the engine for 3 to 5 minutes, can start it up & go once again. Going 40mph increases the odds of the car not moving quicker.
I have a 2002 Santa fe that will not stop running. When the key is turned off the engine keeps running like normal. I changed the ignition switch yesterday. still have same problem.
View 21 RepliesThose are the codes I'm getting. P0340, P1166 and P1167
Here's the story. Engine running flat under load. Easy acceleration is ok, but merging onto the turnpike causes a noticeable loss of power. Replaced the cam sensor, cleared the codes, ran ok for a day. Same codes came back, same flat performance.
Returned the cam sensor with another new one to make sure it wasn't a dud out of the box. Advance Auto Parts is awesome - replaced it no questions asked.
Installed the new cam sensor, cleared the codes. Ran great for a day, then the same symptoms came back, with the same codes. I'm thinking it might be the ECU? If it is, how expensive are they? And do they have to be programmed by the dealer?
This is a 2002 Santa Fe 2.7l automatic with around 147k miles on it.
I have a problem with my 01 santa fe. When I start it the engine runs rough and when u try to give it gas it pops or backfire through throttle body and air intake tube? Checked the timing belt its ok hasnt slipped.so im stuck at this point.
View 8 RepliesI have an odd one; there's a noise that sounds like an consistent electrical snapping noise coming from the engine while running. Everything seems fine otherwise. Just looking for possible things to check.
2002 Santa Fe V6 GLS 173K
When firing up the engine cold it runs really rough, smells very rich all the time, even warmed up. No codes set, fuel trims are within 5-10%. I've replaced the front O2 sensor, swapped crank & cam sensors, Map sensor (have lots of spare parts) & I'm sure there was more things I've changed but can't remember. I have a snap on scanner and everything is within parameters.
I have not checked the EGR valve or solenoids yet. It's a 2006 Santa Fe 2.4l 5 speed, new timing belt & balance belt replaced when I dropped this engine in. Is there a common problem with these that I could begin looking for?
Recently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.
I recently replaced timing belt and balance belt on my 2004 santa fe 2.4l and now the engine runs like crap and shakes badly. I went over all timing marks again and again and I am at a loss.
View 9 RepliesCame out of my house and my 04 Sante Fe will not stay running. It worked fine on the way home form work won't stay started now. You can give it gas and everything but it just dies out after a few moments. I checked most of the basics...
-Fuel pump runs when key is on
-Added gas, over 1/4 tank
-Checked engine fuses
-removed air filters and hoses
-removed mass air intake unit
-down to throttle body and such,
-to keep running by spraying gas directly into engine?
-removed fuel pump under seat
-checked mesh filter and connections
-clean no build up no visual problems with pump or filter
-checked cut off switch, not activated
-removed gas line from injector rail getting good "squirting" from rail
I have asked everyone and most think it is some kind of sensor but I have no light on and I have put it on the OBII and no error codes are found unless I un plug one of the many sensors, which i have done to a few to check them (air mass intake).
03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.
View 12 RepliesI have strange issue with my a/c fan, its running continues even will the a/c switch is off.
I cant stop it. So I have to remove the fuse to stop it. My ac panel is automatic.
Well today I have moved on to the next project on my 02 v6 4X4 Santa Fe, which is the rough running. When I got the car, it had CEL with codes for misfire #5 and lean condition codes. I noticed the wires were in need of replacement (one had black tape wrapped around it) so changed the plugs and wires. The 2 hoses, one that goes between the valve covers on the pass side and the hose between the valve cover and throttle body on driver side were both cracked so replaced them along with a few other vacuum lines, just because I had access to them. Cleared the codes and it still runs like crap, but after 112 miles, town and highway driving, there are no CEL codes. When its first started it idles at 1500 and sounds like its missing and has very little power going down the road. When it warms up seems to run a bit better but still nowhere close to what it should. Equal compression on all 6 cylinders and has power to all 6 injectors and tested to be sure there was a pulse to them as well. Coil packs all tested well. the exhaust is in bad shape and don't know if that would have any effect on how its running.
View 6 Replies2004 Santa fe. Having issues with RPM running high. When car is started, RPM sits at 1500 for a few mins, then drops to 500. Seems to be having issues either getting into gear or staying. At any mph, car seems to surge and not feel like it's getting either gas or power. While on cruise at 55+ mph, car will also surge with RPM dropping 500, then kicking back in. This goes on every few seconds up to random times.
Had it looked at this past weekend at a dealer, and of course it didn't do it one time, after doing it for a half hour prior on the interstate. Tech found no error codes when he checked it as well. Car was fine for an additional 300 miles, then it started again out of the blue. Pulled out at a red light and I though I was going to stall.
Just got laid off so I'm trying to eliminate before putting a lot of money into it if I don't have to. 132,000 miles.
Ok, so I'm working on a 2004 Hyundai Santa Fe, 93,000 miles. The vehicle runs great! So great that you cant get it to stop running!! The problem is intermittent and generally happens after the vehicle has been running for at least 3 minutes. I turn the key off and she keeps on running (not dieseling, but running at 340-450 rpms!) I have already removed the aftermarket remote start that was installed on the vehicle thinking that was the problem, it was not. Then I went to the ignition switch and unplugged that, also to no avail! I plugged my scan tool in and can communicate with the computer and view pids while the key is on. When I turn the key off, I should loose communication. When everything acting normal and the car actually shuts off with the key, I loose communication with the computer upon turning the key off. When I turn the key off and the veh. keeps running, I do NOT loose communication with the pcm. The only way to shut the car off is to step on the gas pedal. Otherwise it'll run at 400 or so RPM for an hour or so!!
View 8 RepliesMy Santa Fe driving me crazy. Have a 2002 Santa Fe 4 cyl with a problem. It will start when cold and run normal about 2 minutes. Then it starts running erratically like a misfire. If you let it idle this way it will stall quickly and not restart until totally cold again the next day. If you catch it quick enough and continually pump the throttle it continues to run rough until it starts to warm up. As it warms up the engine slowly improves until it reaches operating temp. At this point the misfire is much less but still there. If you shut it off for more than 10 minutes it will not start until the next day. There are no codes at this time. I have changed the coolant temp. sensor, the cam position sensor, fuel pump and screen, spark plugs and wires. I have also verified all timing marks on the crank, cams, etc. The crank sensor was replaced about 40k ago when the timing belt was replaced. What can I look for now???
View 2 RepliesFor about 3 years, our SF (about 125,000 miles) has experienced the whirring/whining upon acceleration whenever the AC was running. I didn't do anything about this as the AC still worked well.
Just a few days ago, while running the AC for a "recharge" during our recent cooler weather, I realized that the AC was not cooling below outside ambient temperature, nor was the whirring present any more. I assume that the compressor finally seized. (?)
To keep repair costs low, and based upon the description above, where should I begin to look to see where the problem lies? Is it most likely a seized compressor/clutch? I am unsure if this is the issue, since even when driving with the AC turned to "Max", I now notice NO detrimental effects upon the engine/power output, which makes me wonder if the compressor actually seized. Wouldn't a seized compressor actually be very hard for the belt to turn, or possibly burn the belt?
I know the compressors and AC systems on these cars are notorious for dying too soon...
2001 Santa Fe with 2.4 engine auto FWD 198k miles. When it is started first in the day, the engine sounds good and shifts well. After a few minutes and also after stops, first gear works well but then the following gears do not work well almost as if the engine and the transmission quit talking to each other. Traveling at 60 mph starting up a medium hill, the car downshifted and could not pick a gear. Although I pushed the pedal harder, the car did not respond rather continued to slow down. It acts like I lose 2 of the 4 cylinders in all cases. I replaced the spark plugs and two of them had oil on top of the plugs and also all around the threads. I replaced both coils thinking that one of them was the issue but no change has been observed. I replaced the throttle position sensor; no performance change. I do not believe it is the transmission as I have not notice any clunking, or bad shifting when starting out. While coasting at 40 mph in neutral and my pedal pressed at a certain position, the rpm gauge fluctuated from 3k to 3.6k many times for the duration of 20 seconds.
View 2 RepliesFor about a year now my 04 santa fe whines after running for a long ride. We can never get it to do it to bring to dealership to have them look at since it only does it after long rides. We have had the power steering and transmission flushed and that worked a little while during the fall and winter but now that the weather is getting warmer it started again. What this could be?
View 1 RepliesMy 03 Sante Fe is running a little rough and is stalling. My Mechanic said this P code was going to run me $1300. I'm not very mechanical , but this just seems very high. He said that aftermarket sensors would not work and only Hundai parts for the fix.........
2003 Sante Fe, LX, 3.7 l engine
I have a strange problem with my 2001 Santa Fe GLS that I can't put a finger on.
With my AC running, whenever the condenser fan (the one on the driver side) comes on, the electrical system seems to short out briefly (1/2 sec) - all lights go dimmed, the vehicle bucks - very scary when driving. Sometimes the engine sometimes shut off if idling.
I've changed the AC compressor (twice) and changed the entire condenser fan assembly to no avail.
