drops exactly .27 volts from the factory .503 . I own a spare apps sensor . it does this with both sensors. There is no doubt its he bearing in the bell crank thats causing it.Is the is at idle? What is it normally and when it drops, measured on what plug terminal?
The electrical should not change idle voltage becasue of a loose bushing in the Bellcrank assembly.
500$ is a tuff pill to swallow over a 5$ part. Ill see if I can press it out and buy a new one I guess
