Review on 🔌 Denso 234-4603 Downstream Oxygen Sensor - 4-Connector 33.1” Wire Harness for Enhanced SEO by Robert Toomey

Perfect replacement for my second generation Lexus GS300 (1998-2005) Block 2 Sensor 2. In case you are wondering, the sensor does not connect like the other O2 sensors in the engine bay this car. It appears under the passenger carpet and is tucked in next to the center console where the passenger places their feet. To access this area, remove the plastic paneling at the bottom of the door frame, then you can lift the carpet. The cable length and connection was perfect. Helped clear my code p0430 - Catalyst system efficiency below threshold. Everyone told me I needed a new cat but when I looked at the O2 sensor curve I noticed that sometimes it flattens out. His replacement did it.
