It only has one, and it is in the rear exhaust manifold.
No.
It is called an oxygen sensor socket.
That is the sensor in the catalytic converter.
it is part of the egr valve
It is on the back exhaust manifold.
It has both an up and a down stream oxygen sensor.
A 2001 Dodge Caravan doesn't have a knock sensor.
There is one on each side of the catalytic converter.
Top of the rear exhaust manifold.
There are two. One before and one after the catalytic converter.
There is a problem with the downstream oxygen sensor. I would replace it.
3.3l & 3.8l engines have two, both in the exhaust system, one before the catalyst, one after. exact location where is the front one located exactly
