2005 saab 93 arc convertible. I think it has the B207R engine. 4 cyl turbo. I get the following errors from a scan. B1340, P0340 - issue with camshaft sensor. not sure where this is. Want to check wiring before I replace. P0300 random cyl misfiring - probably related to camshaft sensor problem. B3057 - not sure what this is and B1019. Since most of these seem to indicate wiring problems may be present, does anyone have a url to a video or text page that shows the wiring?
