Passenger side exhaust
It is caused by Bank 2 Sensor 2 oxygen sensor failing.
Bank one sensor one is above the converter.
Bank 1 is the oxygen sensor either screwed into ,or above the catalytic converter. Bank 2 is below the catalytic converter.
It would be the sensor after the catalytic converter.
That would be the sensor after the catalytic converter.
behind the catalytic converter
it is the upper stream o2 sensor before the convertor
Your in luck...that should be the oxygen sensor in the exhaust manifold at the front of the engine compartment. Bank 2 is the bank of cylinders that does NOT contain the #1 cylinder. That bank is bank 1. Sensor 1 is the oxygen sensor upstream of the catalytic converter, and sensor 2 is the one after the cat.
in the exhaust manifold
where is the bank1 o2 sensor at and how do i change it please i need your help
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
In the Lexus IS300, the oxygen sensor for bank 2 sensor 2 is located on the exhaust system, specifically downstream of the catalytic converter on the passenger side of the vehicle. This sensor monitors the oxygen levels in the exhaust gases after they pass through the catalytic converter, helping to optimize engine performance and emissions. To access it, you may need to lift the vehicle and work from underneath, depending on the model year and any aftermarket modifications.
