SOURCE: where is the bank 1 sensor 2 o2 sensor for a 96

Oxygen sensors are numbered by which bank of cylinders they serve. Bank 1 is the left or drivers side bank of cylinders on the 4.3L which has the odd numbered cylinders 1,3, and 5. Bank 2 is the right or passenger side bank of cylinders numbered 2, 4, and 6. The Bank 1 Sensor 1 would be the sensor for the left hand side of the engine AHEAD of the converter. Bank 1 Sensor 2 is the sensor for the left hand side bank of cylinders BEHIND the converter.

SOURCE: where is the oxygen o2 sensor located on 2004

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.

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.

I have a 05 chevy impala check engine code p0036 n p0142 bank one sensor two which sensor do I replace


If you have access to a scan tool, check the signal voltage for the Bank 1,3 oxygen sensor with the engine at normal operating temperature. Is it stuck low currently? If so, increase RPM for a few seconds and see if it affects the reading. If it begins working with increased RPM, check for holes in the exhaust near the O2 sensor that may cause a false lean. If the exhaust pipe is intact, the sensor is sluggish, replace it. If the Bank 1,3 O2 sensor voltage reading remains low with increased RPM, unplug it and then observe the reading. It should have increased to about 0.5 volts or thereabouts. If it did, check for water intrusion or other connector problems. If none are found, replace the shorted O2 sensor.

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

Bank 1 sensor 2 location on a 1996 chevy suburban

Fig. Fig. 5: Oxygen sensor-7.4L engines




Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (the one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Hope helps (remember to rate this).

03 impala, Car has minimum power 0-30 and then full power...Why?


if it said bank 1 lean, probaly it is an o2 sensor, but if bank 1 and 2 are lean then you have a vacuum leak. a hose or the intake. was there 1 code or more?

Have a 2003 Chevy Impala. Check engine light remains on. Scan showed O2 sensor. Could it be a vaccum leak?


Bank 1 is the rear O2 sensor, but experience says to change both. The front one is right behind the engine in the middle of the engine compartment. The rear O2 sensor is on the top of the exhaust pipe, just behind the catalytic converter. But the same code that shows it is the O2 sensor (which is P0420), is the same code for the catalytic converter, or a vacuum leak. Make sure if you do change the catalytic converter, ensure that the new one is OBD-2 compliant. And the vacuum leak could possibly come from the manifold gasket. Let me know what the problem was!
