Ive just changed the left 02 sensor and today i get a code 33 again? why is this.. Jesus it was a bad enough job i wouldnt want to do it again!:confused1:

have you reset the codes on your ecu? could just be showing the old code, take the battery off for a few hours, then check again mate....

yer done that buddy, thanks.

could be a wiring issue then? was the sensor you put in new or a know good one? all the connections clean? (i'm sure you would've checked that tho matey)

yer all connections really clean and was brand new..

you haven't got the plug mixed up with the dett sensor plug have you? they are both the same (just clutching at straws here!)

my det sensor plug is resistored.. and has been for quite some time bud.. lol thanks though..

Are you sure you changed the right side?

33 is left bank as sat in the car?
