It will be on the exhaust more than likely. You have no tear, model car showing so you will need to publish that information to get exact answers

Can someone give a diagram location of up and downstream 02 sensors on 2003 ford expedition?


The upstream O2 sensors are just off the engine exhaust manifolds, the downstream sensor is located aft of the catalytic converter, it is not called an O2 sensor it is referred to as the catalyst efficiency monitor.

2001 Dodge Stratus R/T o2 Sensor Locations


Yeah, you could do that. Bank 1 is always the engine side where the number 1 cylinder is located. Sensor 1 is the first sensor in the exhaust system, nearest the engine. Sensor 2 is always located farther downstream in the exhaust.

Bank 1 sensor 2 location on a 1996 chevy suburban

Fig. Fig. 3: Oxygen sensor-4.3L engines

Fig. Fig. 4: Oxygen sensor-5.0L and 5.7L engines

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).

Exact location of downstream O2 sensor.


Downstream O2 sensor is after (downstream) the catalitic converter on the exhaust pipe. Upstream O2 sensor is after (downstream) the engine exhaust manifold - before (upstream) the catalitic converter. Upstream O2 sensor controls air-to-fuel ratio to yield a small excess oxygen. Downstream O2 sensor assesses the catalitic converter performance.
