Unfortunately, something is faulty with throttle, pcm or wiring. The missing calibration routine uses the same wiring as used when pressing the pedal to make the throttle plate open/close. You'd need a course of electronics to understand servo motor operation with position sensors tied to a computer that controls the servo motor. Spectra Premium’s 100 new Electronic Throttle Bodies are built from the ground up using precise manufacturing and quality control to ensure smooth driving and. So, the symptoms of a bad throttle body will all affect how the vehicle feels responding to your. You control the throttle body position with the gas pedal. Your Vue’s throttle body controls the amount of air that enters the engine. The servo motor isn't measured as there's nothing to measure. Saturn Vue 2.2L 2005, Fuel Injection Throttle Body by Spectra Premium. Common symptoms of a bad throttle body include, dirt and grime, the check engine light, and an erratic idle. This is a closed loop circuit of basic robotics. This pedal position to pcm to throttle plate movement and feedback continues until the throttle position sensors match pedal position until the pedal moves again. As soon as the throttle plate position matches pedal position the ecm shuts off servo motor power otherwise the throttle continues to open. For 2008 Saturn Vue Fuel Injector Connector AC Delco 85934NP 2.4L 4 Cyl. Once a servo motor is powered to run it moves while two position sensors provides feedback to tell the pcm throttle position. ACDelco Fuel Injection Throttle Body Assembly 12568796 02-05 Saturn Vue 2.2L-L4. Drive-by-wire throttles use a special servo motor that only runs when its needed to move something, in this case rotate the throttle plate. Without a wiring diagram, its difficult to know which wires are signals, feedback, and power.
