The internal planar zirconia substrate develops slow response latency or complete heater circuit failure, triggering diagnostic trouble codes such as P0135, P0141, and P0420. This degradation corrupts the ECU's short-term fuel trim calculations, resulting in excessive fuel consumption, erratic idle, reduced power output, and accelerated catalytic converter deterioration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upstream and downstream sensor kit replaces worn factory monitoring units with OE-grade planar sensing elements. The upstream wideband air-fuel ratio sensor (\u003cstrong\u003e234-9049\u003c\/strong\u003e) delivers high-speed microampere signal resolution across transient throttle inputs, enabling precise 14.7:1 air-fuel target tracking. Paired with the downstream monitoring sensor (\u003cstrong\u003e234-4622\u003c\/strong\u003e), both units feature dual-layer 304 stainless steel protection shields, laser-welded sensor bodies, fluoropolymer-insulated lead wires, and factory-pinned weather-pack terminal connectors for a true plug-and-play installation without wire splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Upstream Air Fuel Ratio Sensor (Replaces \u003cstrong\u003e234-9049\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1x Downstream Oxygen Sensor (Replaces \u003cstrong\u003e234-4622\u003c\/strong\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2004-2011 Toyota Camry\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e2AZ-FE\u003c\/strong\u003e (2.4L I4) \/ \u003cstrong\u003eXV30 \/ XV40\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e157-158 hp \/ 162-163 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e234-4622, 234-9049, 89465-33320, 89467-33080, 89465-0R010, 89465-0R080, 89467-42120, 8946506100, 8946502340, 8946506080, 8946506150, 8946506190, 8946516050, 8946533080, 8946533180, 8946533310, 8946533320, 8946533321\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2011 Toyota Camry 2.4L L4 (Base, LE, SE, XLE models equipped with the 2.4L engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the XV30 and XV40 Camry?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2011 Toyota Camry equipped with the \u003cstrong\u003e2AZ-FE\u003c\/strong\u003e 2.4L engine. \u003cstrong\u003eDoes not fit V6 models (3.0L, 3.3L, 3.5L) or later 2.5L 2AR-FE engines; verify your engine displacement before ordering.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo these sensors require wire splicing during installation?\u003c\/h4\u003e\n\u003cp\u003eNo, both sensors feature vehicle-specific OE terminal connectors and matching harness lengths for direct plug-and-play installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand rigorous daily driving conditions, these sensors maintain precise air-fuel monitoring to preserve catalytic efficiency, engine responsiveness, and dependable four-cylinder performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551473959160,"sku":"DS-EPSL7GMN5","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-toyota-camry-2004-2011-2-4l-1.jpg?v=1790796864","url":"https:\/\/performancechiptuning.com\/de\/products\/o2-oxygen-sensor-upstream-downstream-for-toyota-camry-2004-2011-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
