There are 2 oxygen sensors on the 2004 Impala, located under the car near the CAT converter.

Jack up the passenger side or onto ramps to make easier acess.

SOURCE: what is the location ofttgen sensor, bank 2

Its located in the exhaust manifold on the passenger side,its the sensor closest to the rear of the engine.

SOURCE: I have a 2001 chevy

Bank1 ---is always the side of the engine cylinder #1 is on
Bank 2 --- the other side

Sensor1---the ones closest to the engine either in or just before the converter
Sensor2 --- is the down stream or monitor sensor in the outlet of converter

Just replace all upstream O2 Sensors,ones before the converter by 100,000
miles or in your case when they fail

Only a guess but #1 may be on the left side,you don't do just one if you have more
You don't need to do the rear sensors though

2004 Acura TL O2 sensor block 1 sensor 1 location


Proper terminology is Air/Fuel Ratio (A/F) Sensor Bank 1, Sensor 1. It's not an Oxygen sensor, per se. It is a wide range oxygen sensor. It is located in the top of the Bank one Catalytic converter which is at the firewall or windshield bank of the engine. There is no exhaust manifold. The cat converter bolts directly to the head. The A/F sensors screw into tops of the converters.

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.

2004 Chevy Impala SS 3.8L Supercharged: I am getting OBD2 codes P0171 (System too Lean (Bank 1)) and P0420 (Catalyst System Efficiency Below Threshold (Bank 1)). I also found an oil leak today. I...


for p0171, try:
In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect all vacuum and PCV hoses, replace if necessary
Check for a dirty fuel filter and proper fuel pressure
for p0420, try:

Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.

Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).

Inspect the downstream heated oxygen sensor (HO2), replace if necessary

Replace the catalytic converter

Where is the oxygen o2 sensor located on 2004 impala bank 1


I have a 2002 Impala with 3.8L, and just replaced my Bank1 O2.
It is located between the firwall and the middle of the engine, straight down past the spark plugs. Maybe 12 inches from the top of the engine.
As I recall the plug for the sensor is clipped to a bracket at about spark plug level.
I recommend using the crow foot style wrench to remove and install.
