Notes On Intermittents

If code EO17 is history, start engine and enter diagnostics. See ENTERING DIAGNOSTIC MODE  . Operate engine at fast idle Until "AUTO" closed loop status light is turned on. Observe parameter ED34 while manipulating circuits No. 412 and 413 wiring. If parameter changes from fluctuating to fixed at about .45 volts, repair intermittent open circuit. Check for clean, tight, corrosion free connections throughout circuits No. 412 and 413.
