2000 O2 SENSOR FAILURE - 11/26/2006 4:17:34 PM    JOE M   Posts: 2 Joined: 11/26/2006 Status: offline My CE light came on a few months ago. I had it scaned and 2 02 sensor failures showed up. They are p0155 and p0141. Is it possible that both of these sensors could have failed at the same time? Im not a mechanic but to replace them looks expensive. I have 85k miles. I did some research and some mechanics say that when both fail together it could be electrical and maybe not a sensor failure. Also which 2 sensors are these and where are they located. Thanks.
