What would you like to do?
pass.side at exe manifold Bank 1 is where cylender 1 is. Bank 2 is on the other side of which is on the passenger side of the blazer. Oxygen sensor 1 is the first sensor closer to the front of the blazer. Sensor 2 would be past the catalytic converter on the same side.

Thanks for the feedback!
drivers side exhaust before the catalytic convertor
If you have an oxygen sensor problem then there should be a check engine light "on." Have a repair shop scan and diagnosis the problem. You may not truly have a pr…oblem with the oxygen sensor as it could be a vacuum leak that makes the o2 sensor set a code.
The bank 1 sensor 2 on a 1996 Chevy Blazer is mounted in the exhaust. Sensor two is just behind the catalytic converter.
passenger side of car either on the exhaust manifold or in the pipe before the cat converter..... the one behind cat is sensor 2
That vehicle has several O2 sensors and they are all threaded into the exhaust system at various points.
Bank 2 is the passenger side exhaust, sensor 1 is before CAT and sensor 2 is after CAT.
Assuming this is a V-6, bank 1 sensor 1 would be the first O2 sensor in the exhaust on the drivers side of the engine.
Bank 1 sensor 1 is closest to the firewall and located just below the exaust manifold. Easiest to change from under car.
The one after the catalytic converter.
Bank 1 is the pass side.
Passenger side exhaust pipe directly after the exhaust manifold.
What does o2 sensor heater circuit malfunction bank 2 sensor 1 on a 2003 Chevy s-10 pickup indicate and it?
The heated O2 sensor located on the exhaust header pipe directly after the exhaust manifold on the passenger side of the engine is probably bad, replace it.
You have four sensors on the truck, two before the catalyst converter, which you have two of, one on each side. Sensor 1 is the first one in line before the cat, sensor two is… after the cat. Bank 1 is the driver side exhaust system, bank 2 is the passenger side. That being said, your sensor is the first one on the driver side.
On a Ford Expedition : Bank 2 is the drivers side of the engine Sensor 1 is between the engine and the catalytic converter ( upstream )
Bank 1, on a 4.3 L engine would be on the drivers side.
Assuming this is a 4.3 L engine, the bank 1 (driver's side) and bank 2 (passenger's side) O2 sensor would be found threaded into the exhaust system directly behind each bank.
