Dear Scotty, I have a 2011 ram 1500 with a 3.7 L V6. I am having problems with my O2 sensor. I have replaced the sensor five times and after anywhere from 100 to 250 miles it triggers again first I replaced it with a Bosch fan I replaced it with an NTK now I have purchased one for Mopar, and still having the same problem. To troubleshoot. This problem I also swapped sides with the new O2 sensor, having the check engine light also swap sides started bank two sensor, two swapped with the bank one sensor two and the trouble code moved to bank one if I put the new sensor back or back to it. Ken moves back to back to, kind of why I have gone through five different O2 sensors. Please help me figure out what could possibly be causing this and yes I have clean my cats I have replace spark plugs and coil packs. I have done complete fuel system, clean and even replaced one of my cats , I am lost on this one. Please help thank you.
Realize this codes for oxygen sensors that turn your check engine light on are relatively generic codes. You could have dozens of problems causing a codes to trip that if nothing to do with the sensor itself. And that case you're shooting the messenger. Oxygen sensor merely sends information out if the cars running too rich or two lean has different types of problems. It can flag the oxygen sensor code when there's nothing wrong with the sensor. Couldn't be bad. Catalytic converters you're probably going to have to see a real mechanic like made a test that one out with his fancy scan tools and a road test because no systems are rather complex
