Error Code 0150 And 0153

[camlex]

Hello,

It's happened@ 242,000

I got check engine light. Autozone discovered 0150 and 0153.

Please guide me which O2 Sensoe needs to replace.(Bank 2 Sensor 1)?

Where to buy?

Is it easy to replace or take it to mechanic?

Thanks,

I went to Orailly this morning, same code. and it's reset.

no more light.

also went to toyota dealer and bought 2 sensor incase the light show up.

reason bought two, because my mechanic told me to replace both.

but i don't understand, the lexus manual says (front)between radiator and manifold is

Bank 1 Sensor 1 where toyota main tech foreman told me that is Bank 2 Sensor 1.

Please confirm.

I will wait till light shows up again. if not i will return parts.

any idea, how long it will take to show up that CE light.

Thanks,

bank 1 sensor 1 is the right hand bank (rear) bank 2 sensor 1 is the front bank (left).

light might not show up again for awhile...

but in the mean time you could be using up more gas since the o2 sensors might bebad or getting there

As i mentioned earlier,I have parts already. I will try to change today.

Is it easy to open those sensors? how to install?

Thanks,

It was not hard to replace. I started with front to learn connector and replace the rear from top by standing driverside.

both are new. Another 100,000 easy....

I did bought special tools from Oreilly for $10

Thanks for everyone's input. I see improvement on Engine.
