Check the resistance between pin and pin and also between pin and pin of the idle bypass valveThe resistance in each winding should be approximately 50 at 23C (73F)If the resistance of one or both windings is not good, replace the idle bypass valveIf resistance test of valve windings is good, check continuity of circuits A-35, A-36, A-37, A-38
Clean all remaining parts and install the idle bypass valve on the throttle bodyProceed with the CLOSED THROTTLE AND IDLE ACTUATOR RESETSee above
