SOURCE: location of a o2 sensor 2001 nissan maxima

bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

SOURCE: o2 sensor location 1997 pontiac grand am 2.4 4 cyl auto trans

BANK 1 SENSOR 1 IS THE ONE IN THE EXHAUST MANIFOLD. BANK 2 SENSOR 2 IS BELOW THE CATALYTIC CONVERTER.

P0171 SHOULD GO AWAY WITH A GOOD O2 SENSOR BUT DO CHECK FOR VACUUM LEAKS TO BE SURE. 3.1/3.4L ENGINES HAVE A BAD DESIGN INTAKE MANIFOLD GASKET, THE LEAK OIL, COOLANT, AND AIR.

SOURCE: location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

2005 ford escape v-6 3.0.I realize there are 2-o2 sensors on each converter that are engine mounted.Are there any other sensors at the cat down by the resonator ?


first the sensors on the exhaust manifold or before the cat converters are heated oxygen sensors ( not O2 sensors but HO2S sensors)
there are O2 sensors after each cat converter before any muffler

Where is o2 sensor on 2011 equinox 2.4


o2 sensors are after the cat converter
HO2S ( heated oxygen sensor and different operation to O2 sensors) are located in the exhaust manifold before the cat converter

Olds alero 3.4 location for oxygen sensor bank1 sensor 1


O2 sensors ( oxygen sensors ) are located after the cat converter and for bank 1 it will be after the cat converter attached to the manifold closest to the firewall
the sensors that you see in the exhaust manifolds or before the cat converter are heated oxygen sensors (HO2S) and are completely different to normal O2 sensors

How many 02 sensor and how many wire each sensor


depending on the engine make
v8 and v6 have 2 oxygen sensors( O2S) , one after each cat converter with 2 wires and 2 heated oxygen sensors ( HO2S) in the exhaust manifold/ pipe before the cat converter with 4 wires each
6 cyl and 4 cyl engines have one oxygen sensor after that cat converter and one heated oxygen sensor before the cat converter

There are 2 upstream o2 sensors on cadillac sls and 2 downstream. There are 2 exhaust manifolds on the 8 cyl 4.6 L bank 1 sensor 1 which is backside manifold and bank 1 sensor 2 which is front manifol


the back manifold ( closest to the fire wall) is bank l
there are not 2 x O2 sensors up stream
they are heated oxygen sensors (HO2S) and are in the manifold or exhaust pipe before the cat converter
The 2 x O2 sensors are after the cat converter in the exhaust pipe
so bank 1 sensor 1 is a HO2S sensor
there is a difference in the sensors as the HO2S report exhaust gas conditions to the ECM for fuel /air adjustments , have 4 wires and are heated to read the gas correctly
the after cat converter sensors ar O2 sensors and report on the cat converter action to further adjust the air /fuel mix in the ECM

3l, 6 cyl (California emissions). Where is the 4th O2 or (A/F) sensor?


HO2S( heated sensor) are before the cat convertor either in the manifold or exhaust pipe to the cat converter
O2 sensors are in the exhaust after the cat converter/s
I am drawing the difference because they are not all O2 sensors as each has a different operation for the position in the exhaust
the missing one will be in the exhaust manifold or pipe at a convenient position for servicing before the cat converter

Were are the oxigen sensor of jaguar xj6 1997 v6


the will be HO2S sensors before the cat converter ( could be in the exhaust manifold s or in fittings just before the cat converters
the O2 sensors will be after the cat converters
the HO2S is a heated sensor and should have 4 wires to it while the O2 sensors have just 2 wires.

Bank 2 O2 sensor


O2 sensors are after the cat converter
HO2S sensors are in the manifold before the cat converter
bank 2 is normally the front bank

O2 sensor?


O2 sensors are always after the cat converter and HO2S sensors are always before the cat converter.
p0135 refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit malfunction
If it is a straight 6 cylinder engine with 2 cat converters it will be the sensor before the cat converter that connects to the manifold from pistons 1.2.3
If it is a V6 it will be the sensor that is in front of the cat converter that connects to the rear bank pistons 1.2.3. Use the special socket when removing/replacing the sensors to prevent wiring damage
