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.
