Try and put your stock DV on, clear codes and see if it comes back. Make sure all connections are tight and check the vacuum line going to the to ov the DV for vacuum leaks. This will at least help rule out if it is the DV or not.

thanks ,
i've change to stock DV 1 day ago.
but still meets the 17705 error code after i clean all the error code.

the REVO dealer told me that is REVO'S bug.

because another car which also refreshed by REVO met the 17705 too.
