Hey guys,I have a problem with the Oxygen Sensor, computer shows error - P0430 (Bank 2 sensor 2). My car is IS250 and I have opportunity to get parts of the GS300 (2007 year), but I do not know whether the sensor is suitable for my IS250 model. GS300 O2 sensor code is 89465-30820. Maybe someone using O2 sensor from GS model and everything is fine?

Thanks in advance

 

Why do you think it's the sensor? That code (as well as P0420) are frequently caused by an exhaust leak upstream of the secondary catalyst. (often under the heat shield on the Y-pipe) I'd check that first.

 

We watched through the diagnostic sensor functioning and we have seen that the sensor B1S2 is a variable value ~6 till 7.9, but the sensor B2S2 value all the time was 3.9.
Also workshop checked the collector temperature and said temperature is normal (this shows that the catalyst is not jammed).

You think that sensor B2S2 shows a value for exhaust system leak?
