NTK draws on its background as a major oxygen sensor supplier and uses controlled ceramic technology from raw material through finished sensor production. This oxygen sensor is built to match the original service application with the fit, form, and function expected for emission control service. It fits 1997-2000 Mazda Millenia, downstream, and is identified for the exhaust pipe after the catalyst, B1S3. This part cross-references Bosch 13850 and DENSO Auto Parts 234-4037 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues It Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFault codes related to oxygen sensor performance.\u003c\/li\u003e\n\u003cli\u003eIncorrect air-fuel feedback from a worn sensor.\u003c\/li\u003e\n\u003cli\u003eEmissions test failures tied to sensor response.\u003c\/li\u003e\n\u003cli\u003eRough engine operation caused by inaccurate exhaust readings.\u003c\/li\u003e\n\u003cli\u003eService replacement needs for the downstream sensor location.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the downstream location, exhaust pipe placement after the catalyst, and B1S3 application before installation.
