There are 2 O2 sensors. One is in the front (bank 1) before the catalytic converter, between the exhaust manifold and the catalytic converter, and the other is in the rear (bank 2) after the catalytic converter and is screwed in. The front one is heated and the rear is not. That means after the car begins to heat up the front one comes on and the rear is always on.
There is 2, one before and one after thecatalytic converter.
Four cylinder has two. Six cylinder has four.
4 cylinder has 2 6 cylinder has 4
The 4 cylinder models have two oxygen sensors, and the V6 models have four oxygen sensors.
For the 2.2 liter, there are two. One is a pre catalytic converter sensor, and the other is post catalytic converter. They are very easy to access and replace.
4
One on a four cylinder, two on a six cylinder.
If you have a 4 cylinder engine, you will have two. On a 6 cylinder, you will have four.
