Built with high-temperature stainless steel protective outer housings and rapid-response internal ceramic heater elements, each sensor reaches operating temperature in seconds to minimize cold-start emissions. High-density wiring looms resist underbody radiant exhaust heat, while OEM-matched weather-pack connectors mate straight into the factory harness pins without cutting or soldering. Calibrated voltage sweeps ensure reliable downstream catalytic monitoring and millisecond-level upstream lambda detection to protect your catalytic converters and maintain balanced combustion stoichiometry.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Upstream Oxygen Sensors (Pre-Catalytic Converter)\u003c\/li\u003e\n  \u003cli\u003e2 Downstream Oxygen Sensors (Post-Catalytic Converter)\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;\"\u003e2001-2011 Ford Ranger\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;\"\u003e3.0L Vulcan V6, 4.0L Cologne V6 \/ PN105\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;\"\u003e148-207 hp \/ 180-238 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;\"\u003eSG1813, 234-4001, 234-4046, 234-4070, 234-4071, 234-4127, 234-4401, 22013, 22016, 22060, 22071, 22500\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\u003e2001-2008 Ford Ranger 3.0L V6 (Vulcan)\u003c\/li\u003e\n  \u003cli\u003e2001-2011 Ford Ranger 4.0L V6 (Cologne SOHC)\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 PN105 Ranger?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2001-2011 Ford Ranger equipped with the \u003cstrong\u003e3.0L Vulcan\u003c\/strong\u003e or \u003cstrong\u003e4.0L Cologne\u003c\/strong\u003e V6 engines.
