The aluminum and PBT housing is designed for the demands of modern engine management, while the Hall effect sensor eliminates the contact-style wear points found in many original throttle bodies. The Sensor Shield shaft seal adds another layer of protection against contamination that can affect throttle operation over time. This part cross-references Bosch 0280750474 for the same application. It is a practical replacement choice for Porsche Boxster, Cayman, Cayenne, and 911 models where throttle body failure can trigger drivability concerns.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThrottle response problems caused by internal sensor wear\u003c\/li\u003e\n\u003cli\u003eIdle instability related to throttle body contamination\u003c\/li\u003e\n\u003cli\u003eElectronic throttle faults from moisture intrusion\u003c\/li\u003e\n\u003cli\u003eOil-related buildup affecting throttle plate movement\u003c\/li\u003e\n\u003cli\u003eCheck engine lights tied to throttle position signal errors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector style, inlet diameter, and bore size before installation. This throttle body includes a gasket, but mounting hardware is not included. Clean the intake mating surface thoroughly and inspect the throttle body connector and wiring for corrosion or damage before fitting the replacement. After installation, follow the vehicle-specific throttle relearn or adaptation procedure if required by the engine control system.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDorman OE FIX components are built to address common failure points found in original equipment parts by updating the design where possible. Part number 977-689 follows that approach with a non-contact sensor and improved shaft sealing for long-term service in Porsche electronic throttle applications.\u003c\/p\u003e","brand":"Dorman","offers":[{"title":"Default Title","offer_id":52808180596917,"sku":"BKKY-977-689","price":281.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/RB_977689_Fro.jpg?v=1784180424","url":"https:\/\/www.partcatalog.com\/products\/dorman-977-689-fuel-injection-throttle-body","provider":"PartCatalog","version":"1.0","type":"link"}
