Walker 350-34096 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Walker 350-34096 Oxygen Sensor Overview

Walker Products 350-34096 is a heated, threaded oxygen sensor built as a specific-fit OE replacement for select Suzuki applications. It is engineered to deliver the ECU feedback needed for proper fuel control and emissions monitoring on vehicles such as the Suzuki Grand Vitara and Suzuki Esteem.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific fitment. The 350-34096 uses a 4-wire design, a female radiused polygon connector, and an 18.0 mm thread diameter for direct replacement in the listed downstream positions.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for the listed Suzuki Grand Vitara and Suzuki Esteem applications
• 4-wire configuration with 20-gauge wiring
• 18.23 in. wiring harness length and 21.77 in. overall length
• Female radiused polygon connector for application-matched connection
• Threaded mounting with 18.0 mm thread diameter

Application Details

Compatible with 2006-2008 Suzuki Grand Vitara, downstream right; 2006-2008 Suzuki Grand Vitara, downstream left; and 2001 Suzuki Esteem, downstream. This part number, 350-34096, is built for the specified sensor location so the ECU receives the correct exhaust-gas feedback for the vehicle’s emissions strategy.

Walker Products 350-34096 is part of the Walker Products Aftermarket engine management line, which is focused on OE-style replacement sensors and fuel system components. For shoppers searching for a downstream oxygen sensor for Suzuki Grand Vitara or a replacement oxygen sensor for Suzuki Esteem, this part number provides a direct-fit option for the listed positions.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation from incorrect air-fuel correction
• Higher exhaust emissions from a failing downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Verify the sensor position before installation: downstream right, downstream left, or downstream as listed for the vehicle. Inspect the sensor wiring harness and connector for physical damage, and confirm the threaded mounting location and connector style match the original part before replacement.

Because this is a heated oxygen sensor, proper electrical connection is important for accurate ECU feedback. Confirm fitment by year, make, model, and position before ordering.

Quality Assurance

Walker Products has manufactured engine management components since 1946 and operates as an ISO 9001/TS 16949 certified company. The 350-34096 is produced as an application-specific replacement sensor for the listed vehicles and positions.
