What you have to do is replace the o2 sensor on bank 1 sensor 1.This is the front sensor on the left side on the exhaust system.Left side is bank 1 and right side is bank 2.Make sure the connections are good first.Usually it`s the internal heater in the o2 sensor.Hope this helps.Good luck.

Where is the 02 Oxygen Sensor before the cadalic converter on a 2006 Hyundai Santa Fe


Usually these are located on the exhaust manifold or just below the exhaust manifold and you should be able to see it in the engine bay. On V6 engines there will be one sensor on each of the 2 exhaust banks.
You will probably need to remove the engine cover to see the sensors on your exhaust.

If someone told you to replace these because you got a particular fault code I would be wary. A decent scan tool and basic diagnostics can show if the 02 sensor is working or not. Some faults often blamed on an 02 sensor are not due to faulty sensors.

Hey i have a hummer h2 2004 and i have the check engine ligh on the code is p0135 (bank 1, sensor1) what sensor is it? thanks


Hello: Bank 1 tells you it is the side of the engine that has #1 cylinder (Which on your truck is the drivers side) SENSOR 1 IS THE SENSOR FOR THAT BANK IN FRONT OF THE CATALYTIC CONVERTER. This code tells us the heater in the sensor has a problem. You should replace the sensor. (Experience: I highly recommend a GM part. The GM engine control module is very sensitive to 02 sensors). Make sure the truck end of the harness connector is clean and not damaged. After replacing sensor you will have to have the code cleared. (auto Zone, Advance Auto may can do it and not charge you.
