Product Details

Walker Products Aftermarket develops engine management and oxygen/air-fuel sensors as direct replacement parts for many vehicles worldwide. Part number 350-34434 is built for the specified application and mounting position so the sensor can deliver the diagnostic feedback expected by the ECU. On newer vehicles, a failing oxygen sensor can trigger fault codes, affect fuel economy, increase exhaust emissions, and illuminate the malfunction indicator light. This sensor is used on 2009-2010 Suzuki Grand Vitara downstream right and downstream left locations, making it a focused choice for Grand Vitara oxygen sensor replacement service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Higher exhaust emissions from a worn sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the vehicle position before installation: this part is listed for 2009-2010 Suzuki Grand Vitara downstream right and downstream left applications. Inspect the sensor wiring harness and connector for damage before replacement, since physical wear can shorten sensor life and affect operation. Confirm the threaded mounting location and connector style match the original part before installation.

Quality Assurance

Walker Products states that its engine management and oxygen/air-fuel sensors are developed as OE replacement parts and that the company operates under Automotive ISO9001/TS 16949 certification standards.
