SOURCE: how much does it cost to replace a fuel pump on 04

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.

that's actually the output of the vehicle speed sensor.
The input of the speed sensor is actually on the right front wheel assembly. It's the little electrical knob looking thing right behind the control arm.

SOURCE: Check engine light comes on for 2004 Hyundai Sante

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.

Testimonial: "Thanks for the quick response and good questions."
