They are located on the downpipes from the headers.
inside the gas tank.
Exhaust manifold or on catalytic conerter.
Which o2 sensor are you looking for? The rear located near gas tank?
o2 sensor slow to respond bank 2 sensor 1
normally 4. 2 before and 2 after catalyst...
On a Lincoln Town Car : Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
Depends on what the problem is or what code was set.
passenger side is bank 1 the closest to the engine is sensor 1 of the 2 on each side
the exhaust, where every o2 sensor is
It is always located right after the manifold. It looks like a spark plug with a wire going to it.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
