Your question is incomplete. However, the numbers should be GM 12569429, AC Delco 213-1568. For AC Delco, check part pix at Amazon.

Depending on the engine it will have between 4 and 2.

If you had a straight 4 or 6 engine then there would be only 2, one on the exhaust manifold or exhaust pipe and then one just after the catalytic converter.

If you have a "V" engine (V8, V6) then you have an oxygen sensor on each exhaust manifold and will have a catalytic converter for each bank of the V. There will also be an oxygen sensor downstream of each converter as well. In this case there would be 4 oxygen sensors.

Hi, I am getting Faulty codes P0036, P0056, P0141, P0161 in reference Bank 1 and Bank 2 for sensors 2 on 2003 CTS.I was told the sensors where changed but codes still appear?


If the sensors were replaced an DTC'S come back has to be a wiring problem or PCM ,
The ECM detects that the HO2S heater low control circuit voltage is between 2.6-4.6 volts when the heater is commanded OFF, indicating an open HO2S heater circuit.
Is the fuse open?
All four codes refer to the heating element circuit ! there is a relay in the under hood fuse box that supplies B+ voltage to the O2 sensor heating elements . I would change that or test the relay , videos on you tube on testing relays .

I had diagnostics run on my 2004 Jeep Grand Cherokee today and was told it's my O2 sensor, already figured that! It's Bank 1 Sensor 2- is that cylinder 4 5 and 6, post catalytic converter?


bank 1 is the right hand bank looking at the rngine from the front on a convention car or the bank closest to the fire wall on an east west set up
o2 sensors are always after the cat converter
HO2S or heated oxygen sensor which are different to O2 sensors are always in the exhaust manifold or pipe 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

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.
