Engine check light
Was told the engine check light is a "bank 1 sensor" a fuel/ air sensor.
What I read online it is the one coming out of the exhaust manifold. Am I looking in the correct place? It looks like there are 3 on the car (1994 GS 300) at $110 each I dont want to replace the wrong one.
Is the a common problem? At 160k miles seems like it should have lasted longer. Also read that this sensor is only on California cars.
When the sensor is replaced will the check light go out? Or will it have to be reset? Can I reset the light myself?

I would go ahead and replace both primary o2 sensors. They really aren't that expensive if you shop around.
Even if your sensors are working "ok", putting new sensors in can help. I recently replaced mine, and after logging the original sensor vs the replacement, the new one reacts much faster.
Faster reaction, will eventually turn into better gas mileage. I would suggest changing both primary sensors at no later than 150k miles.
All 2JZGE have twin o2 sensors in the manifold. Most, have a 3rd sensor down at the bottom. It's those twin primary sensors that you want to concentrate on.

is there any way to check if they're faulty?
