    I am trying to locate the oxygen sensors that caused code 21 error
    but heard that there are more than 2 oxygen sensors on my car.
    I could see one before the catalyc (spell?) converter and my arm
    could not reach to the socket so I am going to a repair shop.
    But I need to know how many they are going to replace for sure...
    Could anyone tell me how many there are?

    Thank you in advance!

    Your van has one and only one oxygen sensor.
    Nope.

    Thank you very much! The repair shop insisted on that my car has 3.
    He opened the manual (did not show it to me) and suddenly said it has
    two, so I asked him to replace the one before catalyst converter.
    Labor cost $40. No "Check Engine" sign thereafter.
