Installation Notes
Confirm the sensor position, connector style, and thread size before installation. This Denso oxygen sensor uses a threaded mount and a 4-wire male connector, so the replacement should match the original harness and exhaust bung configuration. Verify the vehicle’s emissions calibration notes, especially for California and non-California applications on the Toyota Camry, Toyota Solara, Lexus SC300, and Toyota Supra.
Quality Assurance
Denso manufactures and tests this OE Style oxygen sensor to strict original-equipment standards for exact replacement fit and consistent operation. The design focus is accurate signal response, contamination resistance, and dependable service life on the listed Lexus and Toyota applications.
