77-01 & P0325 Codes Connected
FYI: I have had a P0420 (Catalyst system efficiency below threshold) code for a while which displayed the Check Emissions Light however didn't affect drive-ability. Recently my SH-AWD light came on which disables the rear drive. I checked my codes & it indicated 77-01 Functional Abnormalities of Fuel emissions or auto transmission. P2422 (EVAP CVS stuck closed) P1454 (FTP sensor circuit range) & P0325 (Knock sensor circuit malfunction). I replaced the FTP sensor, Unstuck the EVAP CVS sensor (have a replacement in case i get the error again) however didn't fix the SH-AWD issue. I replaced the Knock sensor which fixed the SH-AWD issue.
