Wouldn't there be a code popping up if that was the case? But I do have a code reader, and I deleted the two codes i had and P0141 came back on right away so changing the O2 sensor was must.
I fixed my driver window, the bracket came off the glass so I re-glued them with some epoxy glue and the also bought some silicone based lubricant to lube up the window guide rails.
I have been having issues with my CAT code P0420 and now a second code has popped up P0141. I did the research and saw its the 02 Sensor that goes right in the middle of the catalytic converter.
So my question is, is the CAT bad that is causing the sensor to go bad, or is the sensor bad which is causing code P0420 to pop up.
Any help or insight would be appreciated. Oh and I live California so apparently there are two different 02 sensors and of course the the sensor with California emissions is the most expensive.
Also another recap on the Check Engine light, "P0420".
Well rather then biting the bullet and paying $700 for a new CAT. I thought it wouldn’t hurt to try and clean the CAT. So I pulled out theCAT, blew air into it with a air gun then soaked the CAT in hot soapy water for an hour or so, then ran water threw it several times, blew air again to dry it. Put it back into the car and the check engine vanished immediately, and I did not remove the battery..
