Welcome to FIxYa.com Important: Removal of the oxygen sensor is easier when the engine
temperature is above 48CC (120T). ' Handle the oxygen sensors carefully in order to prevent
damage to the component. Keep the electrical connector and the louvered end free of
contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle
the sensor. REMOVAL Numbers in ten in parenthesis correspond to numbered
components in image. 1. Raise and support the vehicle. 2. Disconnect the sensor harness connector. 3. Remove the oxygen sensor. Bank 1 Sensor 2(1) Bank 1 Sensor 1(2) A Bank2Sensorl(3) A Bank2Sensor2(4) INSTALLATION Important: A special anti-seize compound is used on the
oxygen sensot threads. The new service sensors should have the compound already applied to
the threads. Coat the threads of a reused sensor with anti-seize compound P.N
5613695 or the equivalent. 1. Install the oxygen sensor. Bank 1 Sensor 2(1) A Bank sensor (2) A Bank2Sensorl (3) A Bank2Sensor2 (4) Important: Make sure that all of the harness retaining clips
are intact. The harness must not contact any of the hot exhaust components. The HO2S
pigtail has white tape at the intervals, indicating the proper location of
each retaining clip. When connecting the sensor pigtail to the harness, ensure that
the connector seal is crushed uniformly all the way around between the connectors. 2. Connect the sensor harness connector. 3. Lower the vehicle
The upstream oxygen sensor is typically found on the exhaust manifold that is bolted to the engine block. It may be as far up on the exhaust as the the manifold piping located in the front of the engine under the hood. The sensor looks like a plug sticking out of the exhaust piping and will be the only plug inserted into the exhaust system.

Very nice well done, JUH
bery well done ,lee

SOURCE: 2000 nissan quest, service engine light on, idles rough...
sounds like it , the sensor should be on the exhaust somewhere,whith wires on it
SOURCE: upstream oxy. sensor signal wire, what color is it?
In my 1990-1995 manual it is Black/Dark Green.
Dark green/orange is 12 V supply, Black is ground, Black/Light Blue also comes from the powertrain control module but is common to many other sensors.
SOURCE: 1997 Dodge Stratus V6 oxygen sensor location
Upstream, as in ahead of the converter, back toward engine. Start at converter and work your way back, should be on exhaust pipe or even on manifold.
SOURCE: replace oxygen sensors
these engines have 1 upstream o2 sensor and 1 downstream o2 sensor..the 1 in the rear exhaust manifold is the upstream and the 1 after the converter is the downstream..make sure you replaced the right one
SOURCE: location of upstream and down stream oxygen
exhaust manifold at rear of engine is ur upstream. follow exhaust past cat conv and u will see downstream
