P1505 & P1507 indicates you may have a bad IACV or you swapped IACV and TPS connectors by accident.
P0445 & P0446 indicate a problem with your EVAP system. I believe it's related to the EVAP purge valve under the throttle body.

You should still receive spark with the CELs you are currently receiving. Generally a spark issue is caused by a weak or no crank signal. Even though you bought a new one you may not have actually fixed the issue. What brand crank and cam sensor did you purchase? Should be Hyundai, NTK, Siemens or Mando ONLY. Do not buy junk from the local parts store or you'll be buying it twice trying to cut corners to rush the repair job.

Did you remove the upper intake or throttle body? If so I'd look into the possibility of swapping the harness connectors and maybe forgot to reconnect the EVAP purge valve harness or vacuum line.

And I think its a duralast sensors for both.
Throw them out and try again with the brands I listed. Our ECU is based on a BMW Siemens MS42/43 design and it's just as finicky as a BMW when it comes to sensor selection.

I would typically recommend against eBay for genuine sensors because they are often times counterfeit sensors marked up as Hyundai... but that seller looks like they might be legitimate. Buy at your own risk.

I personally stick to RockAuto or the Amazon seller "Visit the Hyundai Store" for genuine Hyundai sensors Otherwise you can message Albert Hwang in the Facebook groups, who is our resident parts dealer. He can usually get genuine Hyundai parts to you within 2-3 days. I've had great success with all three sources. If you can't find a part for some reason you can also find them on HyundaiPartsDeal.com but their prices are OFTEN 3x everybody else. I would use them as a last resort.

No clue since the connector is out of focus (but the pulley 1' below looks great).
Is that the sensor, or the connector?
What is in range of what is in your hand?
O2 sensor
AC compressor
Fan wiring
Oil pressure switch on the block?

Looks like a 1 wire harness, correct? I believe that attaches to the A/C pump either to enable the A/C clutch or to detect when there is a load from the A/C system. This allows the ECU to change fuel and idle strategy to compensate for the additional load on the engine. There's actually a map I found in our ECUs that changes idle based on engine load, and A/C is one of these things that triggers the 2nd raised idle speed map. Without it, the engine would stumble as soon as A/C is activated.
