I know this is a electrical problem with the 02 censor... But which 02 sensor is it?

 

says bank 1 so the first one on the header

 

i knew it ****...

 

but it could also be caused from an exhaust leak before or around the cat.. check that before you go out and buy a new o2 sensor

bank 1 reffers to the cylender bank, either 1 or 2 on a flat or V engine. on an I4 there is only one bank. to determine what sensor it is you need to know if its sensor 1 or 2. the code will real bank 1 sensor 1 or bank 1 sensor 2. 1 is upstream (before the cat) and 2 is downstream (after the cat)

 

and i just got a exhaust leak... When i got my clutch done... after that i started throwing this code

 

hmmmmmm sounds like we got a winner!

check the torque on the header and dp bolts

 

what part of the exhaust would they have removed?

 

they might have removed the header idk.. if they did then the head side and the dp flange could be leaking

 

could it have been done by just detching the dp and header

 

what? if somethings not torqued up and its leaking then yes

 

oh ok thanks sir

 

good luck with it

ur brakes ever stop sqeeking?

 

yeah but i still need to get some anti squeal lube
