As the internal zirconia substrate degrades, its response latency increases, causing the engine control module (ECM) to calculate incorrect short-term and long-term fuel trims. This thermal decay leads to hunting idles, fouled spark plugs, unburned hydrocarbon emissions, and inevitable diagnostic trouble codes like P0134 or P0135.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to restore critical closed-loop accuracy, this upstream sensor utilizes a fast-acting ceramic planar sensing element paired with an integrated platinum heater for rapid closed-loop activation during cold starts. The assembly features a high-grade 304 stainless steel protective housing double-laser-welded to seal out moisture and prevent exhaust soot contamination. High-temperature PTFE-insulated wiring harness leads eliminate resistance drift and electrical cross-talk, ensuring exact millivolt signal transmission back to the ECU for stoichiometric combustion control.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e2002-2004 Honda CR-V\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\u003eK24A1\u003c\/strong\u003e \/ \u003cstrong\u003eRD7\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;\"\u003e160 hp \/ 162 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;\"\u003e36531-PPA-006, 36531-PPA-305\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002 Honda CR-V LX, EX (2.4L L4 - Gas)\u003c\/li\u003e\n  \u003cli\u003e2003 Honda CR-V LX, EX (2.4L L4 - Gas)\u003c\/li\u003e\n  \u003cli\u003e2004 Honda CR-V LX, EX (2.4L L4 - Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the RD7 CR-V?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2002-2004 Honda CR-V equipped with the \u003cstrong\u003eK24A1\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this a wideband air-fuel ratio sensor or a narrowband sensor?\u003c\/strong\u003e\u003cbr\u003e This unit is the primary upstream wideband air-fuel ratio sensor required for real-time AFR feedback ahead of the catalytic converter.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eK24A1\u003c\/strong\u003e architecture relies on precise exhaust feedback to balance i-VTEC transition points and stoichiometric efficiency.
