It is in the exhaust manifold next to the firewall.
It is located either on the exhaust manifold or on the exhaust pipe before the catalytic converter.
Start at the exhaust manifold and follow the exhaust pipe toward the rear of the vehicle and you will find the O2 sensor.
It is on the intake manifold near the thermostat.
Look on the exhaust pipe coming off the manifold.
Exhaust system. Usually manifold near port(s).
bank 2 is the drivers side of the engine and sensor 1 is in the exhaust system ( either the exhaust manifold or the EXHAUST PIPE before the exhaust enters the catalytic converter )
Passenger side, exhaust system. Start at the exhaust manifold and go backward toward the converter. You will find the O2 sensor.
The oxygen sensor bank 1 is located in the exhaust manifold. The oxygen sensor bank 2 on the 1996 BMW 328is is located in the head pipe.
The O2 sensor is located on the drivers side exhaust manifold in the down pipe above where it bolts to the exhaust. You'll see it
bank 2 is the driver's side of the engine and sensor 1 is close to the engine either in the outlet of the exhaust manifold or in the exhaust pipe (helpfull)
