Over time, internal heater element resistance drifts and the porous platinum electrode becomes fouled. This latency compromises downstream feedback, triggering false P0420\/P0430 DTCs, causing the PCM to revert to conservative trim maps that increase tailpipe emissions and waste fuel.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-durability exhaust duty, these downstream sensors feature a fast-acting ceramic planar core housed in dual-layer 304 stainless steel protective shrouding. This construction resists thermal shock, oxidation, and particulate buildup. Built with OEM-specification resistance curves, thermal-rated wiring, and factory-matched pin terminals, they restore precise catalytic monitoring to keep the engine management system running in optimal closed-loop operation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Direct-Fit Downstream Oxygen Sensors\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;\"\u003e2011-2012 Ford Escape, Fusion\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\u003eDuratec 25\u003c\/strong\u003e (2.5L), \u003cstrong\u003eDuratec 30\u003c\/strong\u003e (3.0L) \/ \u003cstrong\u003eCD2\u003c\/strong\u003e, \u003cstrong\u003eCD3\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;\"\u003e171–240 hp \/ 171–223 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;\"\u003eBE5Z-9G444-A, BE5Z-9G444-B, BE5Z-9G444-C, 234-4490, BA5Z-9G444-A, BA5Z9G444A, BH6Z-9G444-A, BH6Z9G444A, BR3Z-9G444-A, BR3Z9G444A, 2344490\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\u003e2011-2012 Ford Escape (2.5L I4 Duratec 25, Downstream)\u003c\/li\u003e\n  \u003cli\u003e2011-2012 Ford Escape (3.0L V6 Duratec 30, Downstream Bank 1 \u0026amp; Bank 2)\u003c\/li\u003e\n  \u003cli\u003e2011-2012 Ford Fusion (2.5L I4 Duratec 25, Downstream)\u003c\/li\u003e\n  \u003cli\u003e2011-2012 Ford Fusion (3.0L V6 Duratec 30, Downstream Bank 1 \u0026amp; Bank 2)\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 CD2 and CD3 Escape \u0026amp; Fusion?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2012 Ford Escape and Fusion equipped with the \u003cstrong\u003eDuratec 25\u003c\/strong\u003e 2.5L or \u003cstrong\u003eDuratec 30\u003c\/strong\u003e 3.0L engine.
