It is a new, programmed, and tested unit with a 4-wire, 4-terminal design and a female connector for direct sensor replacement.\u003c\/p\u003e\u003cp\u003eCompatible with Mazda 3, CX-30, CX-50, CX-70, and CX-90 applications listed below, this Walker mass air flow sensor is part of the Sensor Only product line. The 245-1669 is intended for buyers who want a replacement sensor without the housing assembly.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSensor-only design for replacement of the MAF sensing element\u003c\/li\u003e\n\u003cli\u003eStandard replacement construction with specific-fit application coverage\u003c\/li\u003e\n\u003cli\u003eBlack plastic housing with oblong connector shape\u003c\/li\u003e\n\u003cli\u003e4-wire, 4-terminal configuration with one connector\u003c\/li\u003e\n\u003cli\u003eNew, programmed, and production-tested before release\u003c\/li\u003e\n\u003cli\u003eWiring harness included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eWalker Products’ Sensor Only line focuses on replacement sensors rather than complete housing assemblies, giving installers a more economical service option when the housing is still serviceable. Part number 245-1669 uses a pin-style terminal layout, male terminals, and a female connector, with two mounting holes and a plastic housing. Walker’s MAF program is built around custom-tuned flow characteristics and production verification, and the brand states that many of these sensors are manufactured in the USA using OEM-quality components. This part cross-references Walker Products 245-1669 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUnstable idle caused by inaccurate airflow measurement\u003c\/li\u003e\n\u003cli\u003eReduced fuel trim accuracy from a failing mass air flow sensor\u003c\/li\u003e\n\u003cli\u003eDriveability problems related to incorrect air metering\u003c\/li\u003e\n\u003cli\u003eCheck engine light conditions tied to MAF sensor performance\u003c\/li\u003e\n\u003cli\u003eService needs where the sensor element is replaced without the housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eConfirm the connector style, terminal count, and sensor-only configuration before installation. The 245-1669 is a specific-fit part, so match the vehicle application and inspect the air inlet path and connector condition during service. Because this is a sensor-only design, it is commonly used when the housing does not need replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products states that this MAF sensor is 100% new, not remanufactured, and is production-tested for fit, form, and function. The company also notes ISO 9001 and IATF 16949 manufacturing standards, along with on-vehicle verification for calibration.\u003c\/p\u003e","brand":"Walker","offers":[{"title":"Default Title","offer_id":53588240433333,"sku":"DKHD-245-1669","price":278.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/O2_2451669_FRO.jpg?v=1792736702","url":"https:\/\/www.partcatalog.com\/products\/walker-245-1669-mass-air-flow-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
