In most cases, the real problem is simpler: the downstream O2 sensor is reading exhaust gases that are too concentrated. This spacer repositions the sensor 58mm further from direct exhaust flow and filters gases through a built-in catalytic mesh — clearing the fault code permanently.\u003c\/p\u003e\u003ch3\u003eHow It Works\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eSpacer threads into existing M18×1.5 O2 sensor bung\u003c\/li\u003e\n\u003cli\u003eO2 sensor threads into top of spacer — now 58mm further from exhaust stream\u003c\/li\u003e\n\u003cli\u003eBuilt-in sintered filter pre-treats gases reaching sensor tip\u003c\/li\u003e\n\u003cli\u003eECU reads stable signal — fault code clears\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThread: M18×1.5 | Material: 304 Stainless Steel | Length: 58mm\u003c\/li\u003e\n\u003cli\u003eCompatible Codes: P0420–P0424, P0430–P0434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yatexauto","offers":[{"title":"Default Title","offer_id":47197141926071,"sku":"YTX-1027","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/2596\/8567\/files\/c7200871a11e41b68b7bb9271edac1a1.jpeg_tplv-a9rns2rl98-downsize_watermark_1_5_b_76b05546-a619-4ea2-bf6c-c869c558c098.png?v=1774519529","url":"https:\/\/yatexauto.com\/products\/o2-sensor-spacer-m18x15-stainless-p0420-p0434-catalytic-filter-downstream","provider":"Yatexauto","version":"1.0","type":"link"}
