Autel MaxiCOM MK908 Read DTC P0430 on 2001 Chevrolet Corvette

Car model and year: 2001 Chevrolet Corvette

 

GM Scanner to use: Autel MaxiCOM MK908

 

DTCs: 

a P430 alarm indicating problems with bank 2 (image 1)

On my Autel scanner I notice that the voltage on bank 2 sensor 2 is approx. 0.2 lower than bank1 sensor 2 (second screendump).
On my own car (2000 mod) my bank 2 voltages are above 0.8 volts when my cats are hot (image 3)

What I did:

I removed my brakebooster hose to the intake and created lean conditions and all my O2’s responded as the should as the screendump shows below .

As mentioned before everything regarding cath´s and O2 sensors seems to work on my car , but I needed som advice on how to carry out oxygen storage test on my car so I could be able to troubleshoot a P430 alarm
later on .
I think I was able to carry out a storage test on my car and injected propane into the throttlebody to get a fully rich condition as shown on the photoes .
The O2 signals responded as the should on the scanner and shows a delay in oxygen storage capasity in approx. 2 seconds between front an rear O2 sensor respons .
The test should have been carried out with rpm on at least 2k , but injection propane in the engine room and sitting in the car at the same time when you are alone is a skill I do not have yet
so I had to do it on idle rpm

Final Update!

With my Autel , there is no engine speed control like the Verus Pro .
When I go into the Special Functions on my Autel and TAC module I can raise/lower the idle rpm , but as soon as I go out of this view to view O2 values and fueltrim under live data my rpm drops to a normal rpm .
I think I have to use seat forward control together with a piece of wood to raise my rpm to about 2k if I want to view fueltrim and O2 values on my scanner at the same time when the engine run on 2k rpm.
