Here is the definition for the code.
You may need the dealer or a shop to check it out.
P1614 HYUNDAI Description
There is a communication line between Powertrain Control Module (PCM) and Electronic Throttle System (ETS) unit. Using this communication line, various data, such as throttle target angle, TPS output, APS output and diagnostic trouble codes regarding ETS motor, TPS and APS are communicated between PCM
and ETS unit. A malfunction is detected by using a checksum technique
for verifying data. The digital data is composed of zeros and ones. A
checksum is the total of all ones in a string of data. By comparing the
checksum value with a stored value, a malfunction can be detected.
Possible solution- Powertrain Control Module (PCM) harness is open or shorted
- Faulty Electronic Throttle System (ETS) unit
- Faulty Powertrain Control Module (PCM)

Sounds like you might have serious internal transmission problems.
As soon as you can, get someone with a code reader to plug in the vehicle and find out what the code is for the Check Engine light to come on. Might give you a better picture of what`s going on.
It could also (cross your fingers) be something more usual like a clogged transmission filter (located inside the pan), or shift solenoid.
By the way, have you checked the level, look & smell of your transmission fluid?
Level should be checked with the vehicle running, after passing it in all gear ranges on the shifter, and putting it back in park (Check it on "cold" or "hot" level depending on if it`s been driving for a while or not).
As for look and smell, it should be reddish and not smell burnt. Hard to describe the smell of burnt transmission fluid, but normal fluid does not smell too strongly, kind of sweet. Burnt oil is usually black and has a strong odor. If the oil is burnt you have internal damage to the transmission.
One piece of advice I give you is get it fixed as soon as possible because if you don`t already have serious internal transmission problems, the longer you wait, the more chances you have of getting some, to the point of the vehicle just refusing to move. And believe me, speaking from experience, the transition point from the symptoms you describe to total refusal to move and the need for a tow/transmission rebuild is not that long usually.

The filter sits on top of the transmission. look under the hood on drivers side it screws right on top of the transmission. It looks like an engine oil filter.

When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

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.
