Walker 250-241315 Oxygen Sensor - Downstream Right

Walker OE Base Oxygen Sensor for Nissan

Walker OE Base Sensor 250-241315 is a direct-fit oxygen sensor built for specific vehicle applications and downstream right placement. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring on select Nissan Frontier and Nissan Z models.

Key Features

• Heated narrow-band oxygen sensor for OE-style signal output
• Specific-fit design for downstream right installation
• 4-wire configuration with female connector and male spade terminals
• Threaded M18 x 1.5 mounting with 22 mm wrench size
• Wiring harness length: 285.00; overall length: 318.00
• Walker OE Base Sensor line focuses on application-specific replacement sensors

Product Details

Walker Products developed the OE Base Sensor line as an original-equipment replacement solution for vehicles that require precise sensor placement and signal response. Part number 250-241315 is a heated narrow-band oxygen sensor with a rectangular connector, 4 terminals, and a threaded mount for downstream right use. It is listed for 2022-2025 Nissan Frontier, downstream right; 2026 Nissan Frontier, downstream right to 08/2025; and 2023-2024 Nissan Z, downstream right. This part number, 250-241315, is intended for applications where the ECU depends on accurate exhaust feedback to manage emissions and fuel strategy.

Common Issues This Sensor May Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Poor fuel economy caused by incorrect exhaust feedback
• Rough engine operation tied to sensor signal degradation
• Increased exhaust emissions from a failing downstream sensor
• Stored ECU fault codes associated with the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle’s year, model, and downstream right position before ordering. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before installation, since damaged wiring can shorten sensor life and affect readings. Verify thread size, connector shape, and terminal layout match the original unit on the vehicle. This part cross-references no additional part numbers in the provided data.
