You did not mention your engine size, as the 2.4 liter 4 banger, the 2.7 liter V-6 and the 3.5 liter V-6 came in your vehicle.
But you are scaring me. The Bank 1 Sensor 1 oxygen sensor for all three engines is located on the exhaust manifold up top in front of the engine. Open the hood, look straight down at the exhaust manifold, grab the top set of wires leading to the manifold,. and trace down to the sensor. Very easy to access, just need to wait for the sensor to cool before you burn your hands. The 2.4 liter B1S1 sensor is high, the 2.7 and 3.5 liter B1S1 is down low and a reach.
Best thing to get is a special tool made by Lisle that is a special oxygen sensor socket with a slot cut down one side...for the wires. You install the socket on the sensor, lay the wires in the slot, break the torque, remove the wrench from the socket, and just unscrew the socket with O2 sensor. Very wise investment. After the engine cools, the removal and replacement takes three minutes.
Where's my bailout?
