Keep your engine's fuel-trim feedback and emissions monitoring accurate with the DENSO Oxygen Sensor 234-4351. As a downstream (post-catalytic-converter) narrow-band sensor, it measures the oxygen content of the exhaust after the converter and reports it to the ECU so the system can verify catalytic-converter efficiency. It's a direct-fit replacement for the listed applications, including the 2014-2019 Acura MDX [V6-3.5L], 2007-2012 Acura RDX [L4-2.3L], 2015-2020 Acura TLX [V6-3.5L], 2013-2017 Honda Accord [V6-3.5L], and 2016-2020 Honda Pilot [V6-3.5L] — see the Buyer's Guide tab for the full list.
