Product Details

Denso 234-4192 is manufactured and tested to OE standards for accurate replacement in emissions control systems. The sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable sensor operation and long service life. This part cross-references Bosch 13358 and NTK 25160 for the same application.

Compatible vehicle coverage includes Fits 2005-2010 Kia Sportage, Downstream Right; Fits 2005-2009 Hyundai Tucson, Downstream Right; Fits 2004-2008 Hyundai Tiburon, Downstream Right; Fits 2003-2006 Hyundai Santa Fe, Downstream Right; Fits 2003-2006 Kia Magentis, Downstream Right; Fits 2003-2006 Kia Optima, Downstream Right; and Fits 2003-2005 Hyundai Sonata, Downstream Right. Additional coverage includes early-production 2002-2003 Hyundai Tiburon, Hyundai Sonata, Kia Magentis, and Kia Optima applications listed for downstream right placement.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn downstream sensor
• Reduced fuel economy caused by inaccurate exhaust feedback
• Emissions test failures tied to sensor response problems
• Rougher engine operation from degraded sensor output

Installation Notes

Verify the downstream right position, connector style, wire count, and thread size before installation. Match the vehicle’s build date on 2002-2003 Hyundai and Kia applications, since some listings apply only from specific production dates. Confirm the original routing and harness length so the sensor installs without strain or connector mismatch.

Quality Assurance

Denso builds this OE Style oxygen sensor to strict original-equipment standards and tests each component for replacement accuracy and fit. The design emphasizes correct sensor response, contamination resistance, and dependable operation in emissions control service.
