The oxygen sensor is located at the exhaust manifold ,behind engine, close to firewall. The oxygen sensor has no effect on vehicle until it has reached operating temperature or closed loop status in computer. If unplugged or defective computer will substitute a fixed voltage value and car will still run.It will set a check engine light
its built into the bottom of the coolant reserve tank
They are in the exhaust flow
My 1992 Olds Delta 88 has the serpentine belt diagram on the top of the radiator
Remove it carefully, spray the sensor wire with brake clean or alcohol, do not touch it, reinstall.
on a 1994 it's behind the harmonic balancer
under the throttle body next to the thermosat housing.
The oxygen sensor on a 1988 Astrovan is located in the exhaust system. There are two oxygen sensors, one on the driver's side and one on the passenger side of the exhaust.
Check the fuel pump fuse & relay.
