Bank 2 - passenger side. Sensor 1 - before the catalytic converter.
I have a 2001 es and it is in the back between the engine and firewall, down low and you can get to it from the drivers side (not easy to get out).
O2 sensor front of engine aka closest to the radiator. Mounted on the manifold...on the 98' its right in your face when you open the hood.
On a Ford Windstar , V6 engine : firewall 1-----2-----3 ( Bank 1 ) 4-----5-----6 ( Bank 2 ) front of vehicle > driver Bank 2 , Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
On a 2007 Dodge Nitro, the Bank 1 O2 Sensor 1 is located on the exhaust manifold, upstream of the catalytic converter. It is positioned on the driver's side of the vehicle, near the engine. This sensor monitors the oxygen levels in the exhaust gases to help manage fuel injection and emissions.
On a Ford Expedition ( 4.6 and 5.4 litre V8 engines ) Bank 1 is the passenger side of the engine
