The O2 sensor is over $200 US. Not something to be changed on a whim. If the O2 sensor is bad you would get a code 6. The O2 sensors are good for over 100000 miles most of the time.
Intake air sensor... Check its resistance. Should be in the K ohm range. Not an open circuit. Not a short. Check it in place and check its connector. You could remove it and check for machanical damage. There is a small bead thermistor exposed to the air stream.
Check the resistance of the body of the O2 sensor to go ground. The O2 sensor grounds via the exhaust system. If there is resistance, the O2 sensor may need to be backed out and reseated to establish a ground. On your model, you may have two O2 sensors to check.
Sometimes once these things are corrected, the power to the ECU needs to be removed to reset the ECU, as the ECU can sometimes not revert from adapting to a fault, to running normally.
Check the connectors for the O2 sensors. Has the vehicle engine been washed?
