Built with a protective coating and silver-alloy mating for installation durability, the kit addresses common sensor failures that trigger fault lights, rough idle, and reduced fuel economy when the original sensors age or become contaminated.\u003c\/p\u003e\n\n\u003ch3\u003eHow will replacing both upstream and downstream sensors affect engine performance?\u003c\/h3\u003e\n\u003cp\u003eReplacing both sensors helps the engine control unit regain accurate oxygen readings before and after the catalytic converter, allowing better fuel trim corrections and smoother driveability.

Before buying, confirm your vehicle’s engine size, model year, and current OE part numbers to ensure proper match; these sensors are not intended for other Honda platforms like CR-V.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible: Honda Accord 2.4L (2008–2012)\u003c\/li\u003e\n  \u003cli\u003eCompatible: Acura TSX 2.4L (2009–2014)\u003c\/li\u003e\n  \u003cli\u003eNot compatible with Honda CR-V or other unrelated engine variants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This QIJIAUTO O2 sensor pair is aimed at DIY mechanics, independent repair shops, and owners of the specified Honda Accord and Acura TSX models who need a cost-effective, direct-fit replacement for malfunctioning oxygen sensors. If your vehicle shows a check engine light with O2-related codes, experiences rough idling, or has increased fuel usage and you confirmed the engine and year fitment, this kit provides the upstream and downstream sensors necessary to restore proper exhaust sensing. Always verify OEM part numbers and connector type prior to installation and follow proper torque and anti-seize recommendations when fitting threaded exhaust components.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these sensors fit my 2010 Honda Accord 2.4L?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — this two-piece kit is compatible with Honda Accord 2.4L models from 2008 through 2012.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these heated sensors and how many wires do they have?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, both are heated oxygen sensors and use a 4-wire design with female connectors.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"QIJIAUTO","offers":[{"title":"Default Title","offer_id":48085710340254,"sku":"B0D871ZJS4","price":46.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/qijiauto-front-packaging-oxygen-sensor.jpg?v=1785876931","url":"https:\/\/northtrailauto.ca\/products\/qijiauto-upstream-downstream-o2-oxygen-sensor-kit-for-honda-accord-2008-2012-heated-2pcs-direct-fit","provider":"North Trail Auto","version":"1.0","type":"link"}
