Chrysler Repair: Oxygen sensor locations, voyager 3, oxygen sensor

Question
I am looking for a diagram that shows where ALL oxygen censors for a Chrysler 2001 Voyager 3.3 are located.

Hate to have to buy a repar manual just to see where they are located.

Thanks


Answer
only 2  upstream is

REMOVAL - UPSTREAM 1/1 - 3.3/3.8L
Remove battery, refer to the Battery section for more information.
Remove the battery tray, refer to the Battery section for more information.
Disconnect the speed control vacuum harness from servo.
Disconnect the electrical connector from servo.
Remove the speed control servo and bracket and reposition.
Use a socket such as the Snap-On® YA8875 or equivalent to remove the sensor (O2 SENSOR 1/1).
When the sensor is removed, the threads must be cleaned with an 18 mm X 1.5 + 6E tap. If using the original sensor, coat the threads with Loctite 771–64 anti-seize compound or equivalent.


downstream is  after the cat converter under the van.
