I just changed all four oxygen sensors on my 2005 LJ and this thread was perfect.
Also know, how many O2 sensors does a Jeep Wrangler have? Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
Likewise, how many 02 sensors does a 2004 Jeep Wrangler have? Your Parts supply company should be able to tell you for sure but you will have between 3 -4 o2 sensors.
Also, are there 2 O2 sensors? Therefore, while most vehicles have two oxygen sensors, those V6 and V8 engines equipped with dual exhaust have four oxygen sensors — one upstream and downstream of the catalytic converter on each bank of the engine.
People ask also, where is the O2 sensor on a Jeep Wrangler? The oxygen sensors are in the exhaust pipe between the engine and the catalytic converter on the Jeep Wrangler. You will need a special socket to remove the oxygen sensor, available at most auto parts stores and tool supply stores.there’s only two on my 97. like 1BLKJP said, there’s one in the exhaust manifold and one just after the cat.

O2 sensors are a “wear item” and are recommended to be replaced every 75k mi. (if I remember correctly, check the FSM). Consider them part of a really proper tune-up regimen. Simply put, they are providing one set of input for your fuel injection system so it can manage things optimally.
What causes a oxygen sensor to fail?
O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a crack in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).
