Question about 2004 Hyundai Santa Fe

1 Answer

Check engine light comes on

I have an 04 sante fe and had some type of fuel/exhaust sensor replaced after my check engine light came on. It drove ok for 2 weeks then the light came on again but it went out once I turned off the heater/fan in the car, could I possibly be getting carbon monoxide in the vehicle when the heater is on? The manual says when the light is on it is some type of exhaust problem, am having it serviced once again on Monday but just wanted your opinion. Thanks.

Some cars have two oxygen sensors, you might have to have the other one replaced if needed. but your cars not that old and really shouldn't need this. a diagnostic test should pinpoint the problem, but it'll cost you. still, it's cheaper than just replacing parts that aren't fixing the problem.

Check engine light comes on for 2004 Hyundai Sante Fe. O2 sensor was replaced but still has the problem. Does the EGR manifold tend to get clogged up on the Sante Fe? I fixed a Honda Civic check engine...


First of all, why was the O2 snsr replaced?... Check Engine light? What DTC (diagnostic trouble code) did you find stored in the ECU (Engine Control Unit)? The drivability you seem to be describing can have multiple causes -- faulty sensors, malfunctioning computer, clogged catalytic converter, leaky injectors, vacuum leaks, etc.

Ok... this is gonna take some time. The 04 Santa Fe came with 3 (three) different/possible engines -- the 4 Cylinder 2.4 lit, the 2.7 V6, and the 3.5 V6. Only the 2.4 (4 cyl) and the 3.5 V6 are equipped with EGR. The 2.7 does NOT have EGR. To answer part of your question, the EGR system on the 4 Cyl is known to develop restriction(s) in the EGR port (from the # 4 cylinder exhaust port to the EGR valve at the intake manifold). This port travels through the head (front to rear, i.e., Left to Right when viewing the engine from the transmission end). This port cannot be seen at the # 4 cylinder exhaust port unless you remove the exhaust manifold.

It would be very helpful if you could provide more detailed/specific information regarding the drivability issue & what/which codes were found related to the Check Engine light.

There is a cooling fan switch normally located near the thermostat housing or in the head near the thermostat housing. check this and see if it is defective.

How much does it cost to replace a fuel pump on 04 hyundai sante fe?


fuel pumps are kindda expensive, especially on import vehicles. Number one cause for fuel pump failures is heat. When your rinding with the fuel below half, the pump is party exposed inside the fuel tank and when exposed for periods of time it tends to heat up and then gradually burns out cause you to replace it. It's ok to go below half but not to often, I hope it helped abit.
