Where is location of bank 1/sensor 1 oxygen sensor v6 ?


Bank 1 means the side of engine which has #1 cylinder in it, which is the left or driver's side of the engine. Sensor 1 means it is the one closest to the exhaust manifold or before the catalytic converter, better known as "upstream" oxygen sensor. On the 4.3 V6 I believe this sensor is mounted in the exhaust manifold itself. You maybe able to access it from underneath the vehicle, or you may have to remove the "doghouse" interior engine access hood. The oxygen sensor has an electrical connector on it that has to be disconnected and the you may need a specialty socket called an oxygen sensor socket. the size of the hex on the oxygen sensor is 7/8".

Changed sensor 1 bank 1 and found I have four on 96 Yukon makes noise like putting underneath. Now want start. Wuts wrong


tell me did, did skipping start after you replace oxygen sensor or did vechicle already have skip before sensor change if so skipping can be caused by intake leak,bad spark plugs and wires,could have restricted fuel filter, weak fuel pump or weak ignition coil. if skipping occur after you replaced oxygen sensor could have loose sensor or cross thread sensor threads causing exhaust leak around oxygen sensor.

I am trying to locate the Oxygen Sensor on my 2003 Impala?


Chevrolet Impala comes equipped with two oxygen sensors, one on either side of the catalytic converter. Locating the sensors is as simple as crawling under the vehicle.

  1. Location
    • The bank 1, sensor 2 oxygen sensor is located downstream of the catalytic converter. To get to the sensor, crawl underneath the vehicle and trace the exhaust pipe until you reach the catalytic converter. Continue to follow the exhaust pipe until you reach the bank 1, sensor 2 oxygen sensor.

    Identification
    • You should be able to identify the oxygen sensor as a single wire about 3 to 6 inches long. The oxygen sensor is mounted to the exhaust pipe and should slightly protrude from the pipe.

    Function
    • The oxygen sensor is an important part of the vehicle exhaust system. The sensor tests the amount of air in the exhaust stream. It then sends this information to the engine control computer, which determines how much fuel is necessary to maintain a proper air-to-fuel ratio.


If this free advice was helpful, a vote with the thumbs up would be greatly appreciated.

The bank has to do with which side of the engine. The 'Sensor 1' indicates that it is upstream of the catalytic converter.

WELL WHICH OXYGEN YOU REPLACING THE UPSTREAM OXYGEN SENSOR MOUNTED IN EXHAUST MANIFOLD AND THE DOWN STREAM OXYGEN SENSOR LOCATED IN THE EXHAUST SYSTEM AFTER THE CATALYTIC CONVERTER .YOU NEED A OXYGEN SENSOR SOCKET TO REMOVE IT.TO REMOVE OXYGEN SENSOR CRANK VECHICLE TO GET OXYGEN SENSOR HOT BECAUSE HARD TO REMOVE WHEN COLD.BECAREFUL DONT GET BURN ON EXHAUST MANIFOLD WHEN REMOVING OXYGEN SENSOR.AND WHEN INSTALLING NEW OXYGEN SENSOR USE ANTI SEIZE COMPOUND ON SENSOR THREADS.BUT MOST OF THE TIME NEW SENSOR WILL HAVE ANTI SEIZE COMPOUND ON IT.

How do i replace the oxygen sensors?


The oxygen sensor is in the exhaust down pipe just behind the engine underneath the car. You will need a set of ramps and a 17mm wrench (I think). The method is commonsense.
