Usually just have to follow your exhaust manifolds, look for piece (sensor) sticking out 4-5" from side manifold or exhaust pipe with wires attached.

SOURCE: change oxygen sensor

Under hood, center, front engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Front
Under hood, center, rear engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Rear

The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.

  1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
  2. Detach the electrical connector from the oxygen sensor.
  3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.


NOTE A special anti-seize compound is used on the oxygen sensor threads. The compound consists of liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If an oxygen sensor is removed from the engine and if for any reason, it is to be reinstalled, the threads must have this anti-seize compound applied before installation.
  1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
  2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
  3. Reattach the electrical connector to the sensor and the negative battery cable.

you will find it on the exhaust pipe, usually in front of the car. It's the only sensor(s) that's on the exhaust. Some cars have 2 of them, one before and one right after the catalitic converter.
