you shouldn't have to clean it. they can become clogged and stop working if you're running stupid rich for too long periods of time or running leaded gas. the nature of the heater and lean conditions cleans it so to speak.

it wasnt running rich at all and im not running leaded gas, it started working agian but sometimes still has an error code for "sensor error"

Then your sensor is dying. Why is this such a difficult issue for you?

because its not that oldhow old it is means nothing. technical a 02 CAN NOT be dropped more the 8 inches onto a hard surface. i would not put a 02 sensor in at the dealership into a customers car if the parts guy dropped in on the counter.

if its been dropped its done. period i wouldnt trust it.

i've had the same wideband sensor in my car for 5+ years, but the same sensor on the dyno can last anywhere between 30 days and 6 months. sometimes they just go. like dirty said...if they get an impact they can stop working/shorten the life span. leaded gas can too.
