That converter costs about $100
The catalytic converter is in the exhaust next to the side of the trans, the torque converter, if automatic, is inside the bell housing.
Two, one on each side of the catalytic converter.
Upstream is just after the exhaust manifold, and downstream is after the catalytic converter
The 2001 Jeep Wrangler Sahara typically has four oxygen sensors: two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). The upstream sensors are located in the exhaust manifold, while the downstream sensors are positioned after the catalytic converter in the exhaust system. These sensors help monitor the air-fuel mixture and the efficiency of the catalytic converter.
Yes, it is a fedral law that all vehicles built with a catalytic converter have one in working condition.
Yes, if it just started in time you will lose power and speed, replace it, it is breaking up inside.
Two, one on each side of the catalytic converter
The oxygen sensors are screwed into the exhaust pipe on either side of the catalytic converter.
