O2 Sensors are always on the exhaust, follow the exhaust manifold and work your way back, you cant miss them they are round and have 4 wires coming off of them.

Wiring diagram on o2 sensor 2001 impala


Use the right O2 do not use a generic and always replace both sensors if it has a V6. If you don't do the above you will likely get another error code I know this from years of experience on this type of job.

Where are the 02 chevy impala 3.8L o2 sensor locations, I only see three. the top bank one sensor 1 is stripped out, how do i get that one out?


you can apply pressure to the sensor while undoing it to force it out or you will have to cut out the thread area and get an O2 sensor bung hole replacement at an auto supply store and weld into place and install a new O2 sensor. bank 1 sensor 1 is located in the front pipe off the manifold that has cylinder #1 on and bank 2 sensor 1 is on the side that cylinder #2 is on like sensor 1. sensor 3 is the one just before the cat.

Po141 keeps coming on even though the part was changes and the code cleared from computer, why?


The P0141 code refers to your o2 sensor heater circuit. while many times replacement of the o2 sensor can solve this problem you possibly have a short or open in your o2 sensor heater circuit. Also was the proper o2 sensor changed p0141 is the bank 1 number 2 sensor. Bank 1 refers to the side of your engine where the #1 cylinder is located sensor 2 should be the second sensor on that side depending on how many sensors you vehicle has. hope this helps

2001 Dodge Stratus R/T o2 Sensor Locations


Yeah, you could do that. Bank 1 is always the engine side where the number 1 cylinder is located. Sensor 1 is the first sensor in the exhaust system, nearest the engine. Sensor 2 is always located farther downstream in the exhaust.

Where is the location of the o2 sensor in a 2002 chevy impala 3.8l engine?


if you look on the back side of the engine closest to the firewall there will be one in the exhaust manifold. That one will be the bank 1 sensor 1 O2 sensor.

If you look under the car there will be one right after the catalytic converter. That will be the bank 1 sensor 2 O2 sensor

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.

Your car should have two O2 sensors. One will be located after your catalytic converter. The other one should be located before your catalytic converter somewhere between your headers and your cat. Rarely, on some vehicles, there's a 3rd O2 sensor which is located also somewhere between the catalytic converter and the headers.
