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

CEL for my 2005 IS 300 code P0057. Bank 2, Sensor 2. Direct fit made easy with Denso! No cutting wires, no military service. Just connect! Did a little research and found that instead of removing the entire front seat to access the O2 sensor port, some people have moved the passenger seat all the way up and forward. I decided to give it a try, if it doesn't work I'll have to remove the seat. It worked and took about 20-30 minutes! The hardest part was removing the O2 sensor from the catalytic converter. I sprayed some penetrating oil on this thing 24 and 12 hours before launch and it came off with some resistance. Pep Boys instruments for free.
