Top 10 2004 Hyundai Santa Fe Questions & Answers

i have a 2004 hyundai santa fe and i've had the same problems. it's so random when it happens but it seems to be when its a bit warmer outside.. above 70 degrees. it's when i press the gas from a stopped position the car just almost dies. i've pulled out in traffic and thought i was going to get killed. then the car accelerates and the tires squeal and the engine revs super high. the car jerks and its very scary. i bought the car new in 2004 and it started doing it after a few years and it still does it. it's not the gas pedal. it seems like a glitch in the computer or something. it's very dangerous!

crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.

The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.

Crank sensors in engines are usually comprised of magnets and an inductive coil. They are principally based on the Hall effect. Common mounting locations include the main crank pulley, the flywheel, or occasionally on the crankshaft itself.

Some engines, such as GM's Premium V family utilise crank position sensors which read a reluctor ring integral to the Harmonic Balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

I just fixed a similar problem on a Toyota Corolla. I'm not certain if your car's EVAP system setup is the same, but this could resolve your problem as well. Your car may have one or both: A refuel check valve, and/or a fuel cutoff valve. Generally these are located off of the fill tube, but the cutoff valve may be mounted on the fuel tank.
The problem occurs when your fuel tank is overfilled and/or gas flows into the EVAP line. The gas is too high in the filler neck thereby causing fuel to flow into the charcoal canister. A defective refuel and/or fuel cutoff valve would cause this problem. The cutoff valve prevents fuel from flowing into the canister, and the refuel valve helps to trigger the gas pump to stop.

Test refuel check valve (if installed) by blowing air from larger to smaller port. Air should not flow freely and the valve should open as pressure increases. Air should flow freely when blowing from smaller to larger port. Replace valve if it fails either test.

Test the fuel cutoff valve by holding it upright, as installed on car; air should flow freely. Turning upside down should prevent airflow. Also, fuel present in the check valve may indicate the tank was over filled meaning you possibly have fuel in your charcoal canister.

Is your engine warning light on? For the Toyota, code P0441 "Incorrect Purge Flow" was present. Just replacing a defective valve may not get rid of the code. It's possible that your charcoal canister was saturated with gasoline too so that may need to be replaced. I also heard of a situation where the fuel tank was contaminated and had to be cleaned.

Replacing the cutoff valve solved my problem. Good luck! Related Link: http://www.2carpros.com/forum/1998-toyota-corolla-vt190664.html

After change fuel pumps per diagnostics still had problem with starting after fueling. Researched on-line and kept seeing purge control valve as solution. Mechanic didn't think it would do anything but filled up three times now and so far so good. part was $49 and he was nice enough not to charge for labor

If this is what I think it is, on the 3.5 Lit V6, you have an APS (Accelerator Position Sensor) and a TPS (Throttle Position Sensor). The accelerator pedal cable is NOT directly connected to the throttle body plate, it's connected to the APS. The APS sends its signal to the ETSCM (Electronic Throttle System Control Module) which in turn activates the ETS Motor located on the throttle body which opens/closes the throttle plate/butterfly. It's a very sofisticated electronic system. Both the APS and the TPS are known to go bad and simply replacing them is no guarantee of fixing problems in this system (often times it does, and frequently it doesn't). You should first verify there is a problem with these sensors (APS and or TPS). They are basic potentiometers (two circuits in each) which provide data to the computer regarding throttle opening for LOAD calculations (ignition timing, fuel injector pulse width, cruise control operation, etc). Best you have this system diagnosed by a professional technician who knows the system.

I found an answer to this in the reverse direction. While changing my front brakes, I noticed that the sprocket pickup for the speed sensor on the front passenger side half shaft that works with the sensor was cracked and ready to fall off. I removed it so that it wouldn't fly off and puncture a tire. I do NOT have Anti Lock Brakes on my 2001 Santa Fe. I started up the car wondering what to expect and experienced a P0501, P1529, P0500 and a second P0501. Looks like it time for a new half shaft (Axle).

Just helped a friend fix this exact same issue on his 2004 hyundai santa fe. Replaced the purge control valve - a $39 part, even from the dealer. Had to get our hands dirty, but it took literally one single hour to replace the part. Filled it up immediately afterward and no more starting problems. Part is located directly behind the manifold - top, rear of the engine compartment - just between the engine

Synchronization
When
System malfunction. Remote control added or replaced.
How
Access alarm system control module located under driver's side lower fascia Fig. 2 . Set memory switch to SET position. Press remote control lock or unlock button. Set memory switch to OFF position. Confirm synchronization has been successful by locking and unlocking vehicle. Repeat procedure for second remote control. Synchronization can also be carried out using diagnostic equipment.
NOTE: A maximum of 2 remote controls can be programmed. NOTE: If remote control fails, system can be deactivated as detailed in the owner's handbook.

For the 2004 Hyundai Santa Fe:
I do not know if you have the 2.4L DOHC In-Line 4-Cylinder, 2.7L DOHC V6, or the 3.5L DOHC V6 Engine; however the Link below has all three Diagrams.

On the 3 different engines (4 cyl & both V6s) on LH side (radiator side) below the exhaust manifold. All have two14mm bolts mounting them to the engine.
