This oxygen sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management, fuel efficiency, and long service life. If you are replacing a worn upstream sensor on a Pontiac G8, Denso 234-4283 provides a direct-fit solution with the correct connector and threaded mounting style.\u003c\/p\u003e\u003cp\u003eThis part cross-references Bosch 16379 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Sensor Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003eRough idle caused by inaccurate air-fuel feedback\u003c\/li\u003e\n\u003cli\u003eReduced fuel economy from a slow or aging upstream sensor\u003c\/li\u003e\n\u003cli\u003eEmissions test failures tied to sensor response issues\u003c\/li\u003e\n\u003cli\u003eDelayed engine management corrections during closed-loop operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the upstream sensor location before installation and verify connector style, wire count, and thread size against the original part. Because this is a specific-fit sensor for the Pontiac G8, compare the old sensor’s harness length and connector orientation before removal. Use proper exhaust sensor service procedures to avoid damaging the threads or wiring.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDenso manufactures and tests this oxygen sensor to OE standards for exact replacement fit and consistent performance. Part number 234-4283 is engineered for the 2008-2009 Pontiac G8 upstream application and is built to meet the demands of modern engine control systems.\u003c\/p\u003e","brand":"Denso","offers":[{"title":"Default Title","offer_id":52412241805493,"sku":"BBNF-234-4283","price":85.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NP_2344283_Fro.jpg?v=1777787439","url":"https:\/\/www.partcatalog.com\/products\/denso-234-4283-oxygen-sensor-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
