Sensor two is closer to the muffler.
02 sensor is either in exhaust manifold, or in exhaust pipe between manifold and muffler
oxygen sensor is found either in exhaust manifold or in actual exhaust pipe between manifold and muffler
Bank 2 is the passenger side of the engine. Bank 1 is the drivers side of the engine.02 sensor 1 is the sensor that is the closest to the exhaust manifold that bolts to the side of the cylinder head.Sensor 2 is the one that is closer to the exhaust muffler.
There is one cat between the exhaust manifold and cat and one after the cat before the muffler they are easily identified as they are the only things with wires sticking out of your exhaust system but some models have the o2 sensor on the exhaust manifold.
Usually on all vehicles the oxygen sensors are on the exhaust manifold and catalytic converter. On Caravans this is definitely true. The upstream O2 sensor is on the exhaust manifold which is in the front, and the downstream O2 sensor is on the Catalytic Converter which attaches to the exhaust manifold, looks like a small oddly shaped muffler in the middle of the underside of the engine compartment leading to the exhaust system.
O2 sensor is always in the exhaust. Sometimes directly after the exhaust manifold, sometimes next to the catalytic. It will be the only electrical wire on the exhaust before the muffler! Crank sensor I can not help you with on this car. Y-THINK-Y
The catalytic converter will be underneath the car in the exhaust system directly after the pipe that connects the header (exhaust manifold (connects engine to the rest of the exhaust)) to the Cat (catalytic converter). there will also be a resonator that is closer to the muffler end of the exhaust. The cat has an O2 sensor in it so you'll know if you get the right one.
The oxygen sensor is located in the exhaust manifold before the catalytic convertor. If you look down between the radiator and the exhaust manifold a few inches before the exhaust pipe connects to the exhaust manifold you will see the Oxygen sensor. The sensor will have 2 wires coming from it and it kinda looks like a sparkplug stuck into the exhaust manifold. There is 2 nuts that hold the oxygen sensor into the exhaust manifold.
It has 2 ho2s sensors. One is upstream from the catylitic converter between the exhaust manifold and the cat. The other is downstream from the converter between in and the exhaust pipe going to the muffler.
By "exhaust manifold sensor" do you mean the O2 or oxygen sensor? The only sensor I know of on a exaust manifold is the O2 sensor and if you follow the manifold you will see 2 sensors sticking out they will have (usually) green wires coming from them
