If your diagnostic port is throwing P0420 codes or your fuel economy has tanked, your downstream monitoring system is failing to communicate with the ECU.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Symptom:\u003c\/strong\u003e The downstream oxygen sensor serves as the final auditor of your engine’s combustion efficiency. When the factory sensor on your [Engine Code] becomes fouled by carbon deposits or heat-cycled to the point of failure, it sends erratic voltage signals to the computer. This causes the ECU to default to \"Safe Mode,\" often resulting in a rich-running condition that makes the vehicle feel heavy, unresponsive during highway merging, and significantly increases emissions output.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Engineering Fix:\u003c\/strong\u003e This 4-wire downstream sensor utilizes a high-grade zirconia ceramic element to detect the differential between ambient oxygen and exhaust gas oxygen concentrations. By providing a stable, low-latency voltage signal, it allows the ECU to verify that the catalytic converter is processing hydrocarbons correctly. Our replacement sensors feature a precision-wound internal heater that reaches operating temperature in seconds, ensuring your Toyota transitions from open-loop to closed-loop fueling as quickly as possible for maximum efficiency.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhy Mechanics Choose This Kit\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e[Restored Fuel Mapping]:\u003c\/strong\u003e By providing accurate post-catalyst data, the ECU can fine-trim long-term fuel ratios, which is critical for the 1NZ-FXE hybrid systems to maintain their legendary MPG.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e[Rapid Thermal Response]:\u003c\/strong\u003e The integrated heater circuit prevents \"lazy\" sensor syndrome, a common issue on the 1MZ-FE V6 engines where the sensor fails to stay hot enough at idle to provide a reading.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e[OEM-Grade Construction]:\u003c\/strong\u003e Built with a dual-layer protection shield to prevent silicone and lead poisoning of the sensor element, extending the service life under high-heat racing or towing conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width='\"100%\"' style='\"border-collapse:' collapse solid border:=\"\" margin-bottom:=\"\"\u003e\n  \u003ctr style='\"background-color:'\u003e\n    \u003ctd style='\"padding:' border: solid font-weight: bold\u003eFitment Range\u003c\/td\u003e\n    \u003ctd style='\"padding:' border: solid\u003e1992-2009 Toyota Multi-Platform\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style='\"padding:' border: solid font-weight: bold\u003eEngine Platforms\u003c\/td\u003e\n    \u003ctd style='\"padding:' border: solid\u003e1MZ-FE, 3VZ-FE, 1NZ-FXE, 1ZZ-FE, 2ZZ-GE\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style='\"background-color:'\u003e\n    \u003ctd style='\"padding:' border: solid font-weight: bold\u003eSensor Configuration\u003c\/td\u003e\n    \u003ctd style='\"padding:' border: solid\u003e4-Wire Downstream (Post-Catalytic)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style='\"padding:' border: solid font-weight: bold\u003ePart Numbers\u003c\/td\u003e\n    \u003ctd style='\"padding:' border: solid\u003eSG358, 24605, 13353, 15273\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCompatibility \u0026amp; OEM Reference\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFits the Following Vehicles:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1992-1996 Toyota Camry 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2005-2009 Toyota Prius 1.5L L4\u003c\/li\u003e\n  \u003cli\u003e1998 Toyota Sienna 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2000-2005 Toyota Celica 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Toyota Matrix 1.8L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eInterchange Part Numbers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style='\"font-family:' monospace font-size:=\"\" color:=\"\" background-color:=\"\" padding:=\"\" border-radius:=\"\"\u003e\nSG358, 24605, 13353, 15273\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eThe Performance Promise\u003c\/h3\u003e\n\u003cp\u003ePackage includes four (4) Oxygen Sensors for fleet maintenance or full exhaust overhaul.
