What is the location of the oxygen sensor on a Jeep 4.0 liter engine?

Answer by  rusty94 (123)

This jeep has four oxygen sensors, so determine which one you want to change first. One is on the exhaust down pipe, before the rear mini-catalytic converter, another is the same place on the front mini-catalytic converter.
