Product Details

NTK 24281 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement sensors for import and domestic vehicles. NTK uses ceramic-based manufacturing control and extensive testing to support consistent sensor performance and OE-level dimensional accuracy. For Suzuki Grand Vitara oxygen sensor replacement, this part is listed for the upstream left and upstream right positions on 1999-2000 models, including Bank 1 Sensor 1 and Bank 2 Sensor 1 applications.

This part cross-references Bosch 15295 and DENSO Auto Parts 234-4105 for the same application.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn upstream sensor
• Reduced fuel control accuracy during closed-loop operation
• Emissions test failure caused by a failing sensor
• Slow sensor response on a high-mileage Suzuki Grand Vitara

Installation Notes and Tips

Verify the sensor position before installation: this application covers upstream left and upstream right locations on the 1999-2000 Suzuki Grand Vitara. Confirm the 4-wire connector style, threaded mounting, and 18 mm thread diameter match the original sensor before removal. Inspect the harness routing and connector condition during replacement to help prevent wiring strain after installation.
