S7 Warning Erros

[mechtronic]

Hi
I have a S7 set up ECU on Porsche 996TT with legacy expander and Plex SDM 500 dash.
car was working fine we have around 10AEM sensors wire up the system. Clutch pedal
EX Maps (2) FPR, EOP, ECP, CCP, FLEX, MAP sensor. Car did not start now and the warnings I get.
on Smon are "Inputs U24 (Turbine inlet Pressure) Voltage limit voltage failure Share commons Failure
and U25 Voltage Limit Voltage Failure Slave Common Failure Fuel composition no signal salve comms failure.
Any idea where to look for these warnings? Any help will be appreciated.

Is this a new install ? has it ever ran before ? other ?

Do you have these inputs in use, and assigned correctly in the I/O configuration ?

Post a screen shot of Scal during this.

Those are also the questions I am wondering.

If you have a multimeter, measure the voltage readings directly at the sensor connectors to see if they are within the expected range.
