Walker 350-35152 Oxygen Sensor - Upstream
OE Replacement Oxygen Sensor for Mazda
Walker OE Replacement oxygen sensor part number 350-35152 is a specific-fit, heated wide-band sensor engineered for direct replacement in select Mazda applications. It is built to provide the ECU with the diagnostic feedback needed for proper fuel control and emissions monitoring.
Compatible with upstream positions on 2018-2025 Mazda 3, CX-30, CX-5, CX-50, CX-3, and Mazda 6 applications listed below, this sensor supports accurate air-fuel ratio reporting in vehicles that rely on wide-band sensor input.
Key Features
- Walker OE Replacement line for application-specific fitment
- Part number 350-35152
- Heated wide-band oxygen sensor design
- Specific fit for the listed Mazda models and positions
- 5-wire configuration with 715 wiring harness length
- M18 x 1.5 thread size and 22 mm wrench size
Product Details
Walker Products designs its engine management and oxygen/air-fuel sensors as OE-style replacements matched to the vehicle application, mounting position, and ECU feedback requirements. The OE Replacement line focuses on direct-fit coverage for modern emissions systems, making 350-35152 a practical choice for Mazda 3, Mazda CX-30, and Mazda CX-5 upstream sensor service where wide-band signal accuracy matters.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Check engine or malfunction indicator light related to oxygen sensor performance
- Poor fuel economy caused by incorrect air-fuel ratio feedback
- Rough engine operation tied to faulty upstream sensor data
- Higher exhaust emissions from inaccurate ECU input
- Stored fault codes in the ECU linked to the affected sensor circuit
Installation Notes
Verify the connector, wiring harness, and sensor body for physical damage before installation. Confirm the vehicle position and thread specification match the listed application, especially for upstream service on Mazda 3, CX-30, CX-5, CX-50, CX-3, and Mazda 6 models. Because this is a specific-fit wide-band sensor, correct application matching is important for proper ECU feedback.
Quality Assurance
Walker Products has manufactured engine management components since 1946 and operates as an ISO 9001/TS 16949 certified company. The 350-35152 oxygen sensor is produced for the stated application and fitment position to support OE-style replacement requirements.
