Yes, the O2 sensor is on the bottom side of the exhaust manifold elbow. the wires should be routed under the battery and be connected to the wiring harness along top of the passenger side fender well inside the engine compartment. The connections are pretty close to the windshield washer bottle.
You can check the sensor for proper voltage. Simply unplug the sensor, connect a meter to the single wire lead from the sensor and the other lead to ground. start the engine. With the engine warm, the voltage should read between 0.4Vdc and 1.0Vdc. The preheater wires can be checked for resistance as well. Place you meter across the two terminals (one lead to each of the terminals) the readout should be around 4 ohms.
Hope this helps,
Don
