hi gearhead1011 you're right, the code is p0141, and i've changed the downstream sensor (bank 1 sensor2) behind the cat, and there is only one downstream. ive actually changed it twice! the first time i did it i had to change the thermostat and the ect, those codes went away but i'm still getting the sensor heater malfunction. i'm f ing sick of it! gas is to darn hi to be riding around wasting it. anyone PLEASE help

The code p0141 shouldn't have an effect on fuel economy. That code just indicates a problem with the heater circuit for that sensor. You can resistance test the heater circuit in the sensor but considering you have changed twice it's not likely you still have a bad sensor. Sometimes when the sensor fails it shorts the heater to ground and will blow the fuse for it. Then after replacing the sensor there is still no power for the heater and it will continue to set the trouble code. There should be a 20 amp fuse in the underhood fusebox for the rear O2 sensor heater.
