How to Locate and Service the Downstream Heated Oxygen Sensor on a 2.4L Engine on 2008 Chrysler PT Cruiser?

Behind the catalytic converter in the exhaust pipe, the 2.4L engine's downstream heated oxygen sensor can be found. Service the engine by first unscrewing the air cleaner lid and removing the make air hose and then remove the negative battery cable. After the vehicle is raised and supported, pull out the electrical cable from the sensor. After that, pull the sensor electrical harness off of the body clips. After everything is disconnected, use a special oxygen sensor crow foot wrench to take it out.
