HiCustomer

 

There are (4) O2 sensors on that car, one in each exhaust manifold and one in back of each catalytic converter.

 

Thanks for your question and positive feedback,

<p>Actually there are only o2 sensors on your car.</p><p>There is one on the bottom of the exhaust manifold for one of the banks and the other one is located behind the center exhaust pipe midway down the vehicle and it routes into the cabin to plug into the vehicle inside.</p><p>The 2 sensors on the front of the exhaust manifold are air/fuel ratio sensors. </p>
