Post OBD-II Error P0430 - O2 Sensor
on: July 5, 2018 (GMT)

Hi all,

My IS250 (2006) been showing error P0430 every 3-4 weeks when I drive 60+mph for almost 6-8 months now. After doing lots of Google-ing and speaking to few car mechanics I “think” the problem is with the o2 Sensor Bank 2 sensor 2 (in UK, Right hand driver side after the catalyst converter, correct me if I am wrong). I’ve also used Seafoam recently.

I’m trying to determine if problem does lies within o2 sensor, I’ve been using OBD-2 adaptor and Torque Pro App.

First 3 screenshots taken before the use of Seafoam treatment, whilst the car engine was cold and last 4 after the Seafoam treatment and driving for 30+min.

My question is, does the reading on the screenshots seems normal and is this the correct way to determine if o2 sensors are working?

Before the use of Seafoam and whilst engine was cold.

After the Seafoam treatment and warm engine×975/screenshot_20180705_081546_a9dd1723cd97209efea7b75910913afafd3b8e03.jpg
