Hi all,

Over the weekend, the infamous "Service Engine Soon" light came on in my 2000. I have an OBD II code scanner and received the following : Error code P0141, 02 sensor heater circuit malfunction (Bank 1 sensor 2). The light on the dash has since gone off. I gather it has something to do with the oxygen sensor. Is this something I should be concerned with. My 'Lade seems to run just fine, getting over 20 mpg on the open road with the light on. Any help will be appreciated. Thanks.

O2 sensors go bad after enough miles, the code maybe telling you it's time for replacement. :)
