You will find the 02 sensors on the exhaust manifold. Rather a nightmare to replace!
Under van on exhaust front of catalytic converter, there may also be one on exhaust manifold should be able to see through wheel opening, if you have any further questions feel free to ask. Thank you.
SOURCE: where is o2 sensor located
hey there ,,the o2 sensor is located on the exhaust pipe itself..should be a size 22 with wires coming out of it connected to a plug,,,

lOOK UNDER THE REAR OF THE VEHICLE ABOVE THE SPARE TIRE ON A CROSSMEMBER BETWEEN THE FRAME RAILS.

Should be in the manifold on the back side closest to the firewall.

The Intake Air Temperature (IAT) sensor determines the air temperature
inside the intake manifold. Resistance changes in response to the
ambient air temperature. The sensor has a negative temperature
coefficient. As the temperature of the sensor rises the resistance
across the sensor decreases. This provides a signal to the PCM
indicating the temperature of the incoming air charge. This sensor helps
the PCM to determine spark timing and air/fuel ratio. Information from
this sensor is added to the pressure sensor information to calculate the
air mass being sent to the cylinders. The IAT is a two wire sensor, a
5-volt reference signal is sent to the sensor and the signal return is
based upon the change in the measured resistance due to temperature.

Hope helped.
