Product Details

Walker Products engine management sensors are developed as OE-style replacements for vehicle-specific applications. This oxygen sensor is made for upstream placement on the 2009-2010 Suzuki Grand Vitara, including upstream right and upstream left positions. The heated design helps the sensor reach operating temperature quickly so the ECU can receive the signal it needs for air-fuel management and emissions control. If you are replacing a failed Suzuki Grand Vitara oxygen sensor, 350-34158 provides the application-specific fit and connector layout required for the listed vehicles.

Common Issues This Sensor Can 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 failing upstream sensor
• Stored ECU fault codes tied to the oxygen sensor circuit

Installation Notes and Tips

Install this sensor in the specified upstream position only: Fits 2009-2010 Suzuki Grand Vitara, upstream right, and Fits 2009-2010 Suzuki Grand Vitara, upstream left. Before installation, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since damaged wiring can shorten sensor life and affect signal quality. Confirm thread size, connector shape, and harness routing against the original part before final tightening.
