BDFHYK Oxygen Sensor Downstream O2, Compatible with Honda CR-V 2002-2004 l4 2.4L, 234-4125, 36532PPAA01, Replacement 1PCS

This BDFHYK 234-4125 downstream O2 sensor is an OE-style aftermarket replacement for listed 2002-2004 Honda CR-V 2.4L L4 applications and cross-references 36532PPAA01. Before ordering, confirm the 2.4L engine, downstream exhaust location, original sensor number, connector, wiring, lead length and emissions configuration. Similar CR-V model years can use different sensors by engine or position, so compare the removed sensor before installation. A stored diagnostic code alone does not confirm downstream oxygen sensor failure.

234-4125 Downstream Sensor Position Check

This SKU is listed for downstream use. Do not assign a universal Bank 1 Sensor 2 or Bank 2 Sensor 2 label without service information for the exact vehicle and engine.

234-4125 O2 Sensor Diagnosis Before Replacement

Inspect wiring, connector condition, heater circuit, related fuse, exhaust leaks, fuel-control faults, misfires and catalyst operation before replacement. P0420 or P0430 does not automatically prove the downstream oxygen sensor is defective.

• Compare the connector, lead length and original reference with the removed sensor.
