Review on 🚗 Denso 234-4517 Oxygen Sensor: Achieving Optimal Fuel Efficiency and Emission Reduction by Tony Reid

Revainrating 5 out of 5

Perfect fit, direct replacement for IS300 B2S2 sensor!

I delayed a P0161 fault on my '02 IS300 for probably about 2 years because everything on the internet pointed to removing the passenger seat and reconnecting the wires. I was sure there had to be a better way - and there was! This sensor was a direct replacement for the B2S2 sensor (right after the Y-tube). After fighting and eventually defeating a sensor with an over-the-top PB blaster that had been connected to the car for 153,000 miles, that sensor slid like a dream.
