Let me guess you have a service engine soon light on and the computer is saying it's your Oxygen sensors. Oxygen sensers are normally located on the exhaust pipe, within 12 inches of the exhaust manifold, you will probably have to get underneath the van to see them. I think it's just emissions stuff nothing real important
There are two screwed into the exhaust pipe behind the engine.
In the exhaust pipe on the back of the engine.
Depending on the year and engine it may have 1, 2, or 4.
Two, one before the catalytic converter and one after.
2, one before and one after the catalytic converter
No, the connectors for the sensors are different
are you looking for a sensor or are you yring to locate all the sensors. they are located all over it just depends which one you are looking for
It is on the back exhaust manifold.
They are on both sides of the catalytic converter.
