Default 2001 Lexus LS430 C1739 error

Hello!

I have a 2001 Lexus LS430 UL which had a bad rear right height sensor. I had the sensor replaced with a known working unit. Using techstream, I had the codes (bad height sensor RR/ height control solenoid circuit RR) for the air suspension erased but I keep on having the C1739- Height control solenoid circuit RR, error code.
The code will always erase, the air compressor will run, but the code will come back after 30 seconds. I have searched and found nothing in regards to this code, any input or advice would be appreciated!

Thank you

thanks for the reply!

Quick question, to check the height control solenoid valve it says to remove the luggage compartment trim front cover, any idea where this is?
