P0722 = Pulse Generator B, open.

All other codes are not found in our database.

For 2002 model P1529 = Transaxle Control Module error - Invalid message. No information whatsoever on causes etc.

Still could not find any reference to the other two codes.

Hi, not sure if you got your car fixed but codes p1801 is EEPROM error and p1805 is immobiliser transponder error both linked as I have them come up on my Kia Sedona, and Kia being owned by Hyundai I'm guessing same codes will be used

Thank you for all your help, we fixed these two problems but now I have another problem that the car isn't starting on parking - just on neutral, do you know what can be the cause of this?

Sounds like park isn't fully engaged, maybe worn selector

Is the P indicator light showing in dash?
Problem is a fault with the Park and Neutral Position switch, located on top of transmission at end of shift cable. It could be faulty or out of adjustment.
This should be the cause of P1529. Check the switch wire connectors for damage/contaminations due to water entry etc.
