• Replaces Honda OEM Part Numbers 36531RDMA01 and 36531RCAA02 - direct plug-and-play replacement for all listed Honda and Acura applications using these OEM part numbers
• Replaces GM OEM Part Numbers 12581687 and 12581688 - direct replacement for Saturn Vue 3.5L applications
• Also replaces Denso 234-5010, Bosch 13965 / 15401 / 15402 / 15906 / 15910, Standard Motor Products SG916 / SG926 / SG1721 / SG1722, and numerous other aftermarket cross-references
• Common diagnostic trouble codes associated with a failed AFR sensor on these applications include P0131, P0132, P0133, and P0134 - a stored DTC in these ranges indicates the ECU has detected an issue with the upstream air/fuel mixture signal
• Sold individually - one (1) sensor per listing

Features

• OE Identical construction - the NTK 24302 is manufactured to the same specifications as the original equipment sensor installed at the factory on all listed Honda, Acura, and Saturn applications; NTK is the world's largest supplier of OEM oxygen sensors and manufactures sensors for Honda, Acura, and most major automotive OEMs as a Tier 1 supplier; the OE Identical designation means the sensor uses the same ceramic element technology, connector specification, wire length, and harness hardware as the factory unit - not an approximation or substitute, but the same product supplied to the vehicle manufacturer
• 5-Wire Wideband Air/Fuel Ratio technology - this sensor uses wideband (also called broadband or wide-range) sensing technology rather than a conventional narrowband oxygen sensor; where a narrowband sensor produces a simple rich/lean binary signal that switches between approximately 0.1V and 0.9V, the wideband AFR sensor uses a sophisticated planar zirconia ceramic element and a pump cell to produce a precise, linear output signal proportional to the actual air/fuel ratio across a wide range (from extremely rich to extremely lean); this allows the ECU to perform fine-grained, continuous fuel injection and ignition timing adjustments in real time rather than hunting between rich and lean states
• Planar zirconia ceramic sensing element - the NTK 24302 uses a flat planar element design rather than the older thimble-style construction; the planar element integrates the heating element and sensing element in a compact, thin flat tip that reaches operating temperature faster, requires less heater power, and enables the more compact sensor body design used in modern V6 Honda and Acura engines
• Advanced dual-coated platinum interface - NTK's superior platinum coating on the sensing interface provides faster light-off and response times than standard platinum coatings, with enhanced durability against electrode contamination and wear over the sensor's service life
• 3-stage contaminant-resistant plasma jet and deposit trap overcoat - protects the ceramic sensing element against poisoning from fuel additives, silicon compounds, lead traces, and other exhaust contaminants that can degrade conventional oxygen sensor elements; extends service life in real-world driving conditions across all listed applications
• Heated sensor design - the integrated heater element brings the sensing element to operating temperature within seconds of engine start, enabling closed-loop fuel control to begin immediately after cold starts rather than waiting for exhaust heat alone to activate the sensor; reduces cold-start emissions and improves fuel economy during the warm-up phase
• Tarnish-proof electrodes - platinum-coated electrodes resist oxidation and contamination over the sensor's service life, maintaining accurate output signal characteristics and extending the interval between replacements
• Porous PTFE filter - a breathable polytetrafluoroethylene filter allows atmospheric air to reach the reference chamber of the sensing element while preventing moisture, dirt, and contamination from entering the sensor body; maintains accurate sensing by ensuring the reference air side remains clean
• Corrosion-resistant, rugged and watertight housing - engineered for the thermal cycling, moisture, and vibration of the exhaust environment on all listed Honda and Acura applications
• OEM-specified water-resistant connector and harness hardware - the grey rectangular connector and 11.5-inch (290mm) harness plug directly into the factory wiring harness on all listed applications without modification, splicing, or adapter; true plug-and-play installation
• Individually tested during manufacturing - every NTK sensor is functionally tested before packaging to guarantee output accuracy and reliability; unlike mass-sampled quality control, 100% individual testing ensures no defective units reach the customer

Product Description

The NGK NTK 24302 is an OE Identical 5-wire wideband Air/Fuel Ratio sensor covering the upstream position on V6-equipped Honda Accord, Honda Pilot, Honda Odyssey, Honda Ridgeline, Acura TL, Acura MDX, Acura RL, and Saturn Vue applications from 2003 through 2008. NTK is the world's largest OEM oxygen sensor supplier and manufactures sensors directly for Honda and Acura as a factory-level Tier 1 supplier - the OE Identical designation means the NTK 24302 is the same product supplied to the vehicle manufacturer, not an aftermarket approximation. It replaces Honda OEM Part Numbers 36531RDMA01 and 36531RCAA02 as a direct plug-and-play replacement with OEM-specified connectors, correct harness length, and identical sensing element technology.

The wideband AFR sensor technology used in the NTK 24302 is fundamentally different from conventional narrowband oxygen sensors - where a narrowband sensor produces a switching rich/lean binary signal, the wideband planar sensing element produces a precise linear output proportional to the actual air/fuel ratio across a broad measurement range. This allows the ECU to make continuous, fine-grained fuel injection and ignition timing adjustments in real time, resulting in optimized combustion efficiency, reduced emissions, and improved fuel economy across all driving conditions. A failed or degraded wideband AFR sensor causes the ECU to fall back to open-loop fuel control, typically triggering DTC codes P0131-P0134 and resulting in increased fuel consumption, rough idle, reduced power, and potential catalytic converter damage from prolonged incorrect air/fuel ratio operation.

All NTK sensors are individually tested during manufacturing to guarantee output accuracy - not batch-sampled but 100% functionally tested per unit. The 3-stage contaminant-resistant overcoat, dual-coated platinum interface, and porous PTFE reference air filter are NTK's advanced manufacturing features that extend service life beyond conventional aftermarket alternatives. Confirm your specific engine displacement (V6 only) and sensor position before ordering. Sold individually.
