Question about 2003 Chrysler PT Cruiser
4wires from o2 sensor
black, white, white, and grey/lightblue
question is (which is what) out of these wires??
guess black is ground, but the rest??
I had a similar problem with my car. It turned out the O2 sensors were fine and the issue was a leak in the throttle body causing the engine to run lean. If you have an ODB2 scanner you can look at fuel trims, etc and will be able to tell.

the fact that you replaced the sensor and the same code is there means the sensor is functioning ok, you have another problem, code readers just tell you what caused the mil light to go on, not the problem, for that you have to scan the engine on a reader and get readings from sensors and actuators, it could be a plug, vacuum leak egr malfunction, injector malfunctioon to name a few, do yourself a favor and get the engine analysed
