94 S420 . I was checking the back firewall where the crank sensor resides . It's under a plastic cover deep inside , I think the tranny or back of the engine . Alongside that dark alley , I saw a white about a quarter or smaller size hose running alongside that area and it's not plugged . It runs past the crank sensor area and goes further down towards the tranny . Where on the tranny do this white plastic hose gets plugged ?
