BDFHYK Oxygen Sensor Upstream Downstream O2, Compatible with Acura NSX, Compatible with Honda Odyssey Prelude, 234-4092, 36531P5M004, Replacement 1PCS

This BDFHYK 234-4092 O2 sensor is an OE-style aftermarket replacement for listed Acura NSX, Honda Odyssey, Honda Prelude and Isuzu Oasis applications. The required upstream or downstream location varies by application. Before ordering, compare the original sensor number and confirm the exact year, engine, emissions configuration, connector, wiring, lead length and exhaust position. A Check Engine Light or stored diagnostic code alone does not confirm that the oxygen sensor has failed.

234-4092 Upstream and Downstream Position Check

This sensor is listed for different upstream or downstream positions depending on the application. Do not assign a universal Bank 1 Sensor 1, Bank 1 Sensor 2, Bank 2 Sensor 1 or Bank 2 Sensor 2 location without vehicle-specific service information.

234-4092 O2 Sensor Diagnosis Before Replacement

Inspect the connector, wiring, heater circuit, related fuse, exhaust leaks, intake or vacuum leaks, fuel pressure, injector operation, misfires and catalyst condition before replacement. Fuel-trim or catalyst-efficiency codes require system diagnosis rather than automatic sensor replacement.

234-4092 O2 Sensor Installation Notes

• Allow the exhaust system to cool before service.
• Use an O2 sensor socket or suitable wrench.
• Compare the connector, lead length and reference number with the removed sensor.
• Inspect bung threads and start the sensor by hand.
• Use anti-seize only when permitted by the sensor instructions.
• Tighten to the applicable vehicle service specification and route the harness away from heat and moving parts.
