Oxygen Sensor - Gs300

Recommended Posts

kglam    0

Hey Everyone,

My 1994 GS300 Check Engine light is on and I took it in for diagnostics. The mechanic told me that the O2 Bank 1 Sensor 2 is bad.

I have a couple of questions.

1. How many O2 sensors are on the car? I see one on the front exhaust manifold and apparently there is one after the catalyst. Is there also one directly in front of the catalyst as well?

2. Which sensor is Bank 1 Senosr 2?

Thanks for your help!!!

an educated guess would be on the exhaust manifolas it says bank one

you donl;t have 2 banks as you have an inline 6 not a v6 which has 2 banks

there may be another sensor you can;t see on the exhaust manifold towards the firewall as the fron one closer to the rad should be sensor 1

Bank 1 sensor 2 is after the cat. You only have 2. I recommend Oxygensensors.com They have excellent prices and service.

If you're not sure if your car is California emissions certified, just look at how many wires are on the sensor. One wire is standard 49 states emissions, four wires is California emissions. They ask you this on the site.
