So I let Tires+ work on my car out of need one day (Broke down by work and I needed to go home). Few weeks later I get an 02 sensor error (P2626). I assumed it just went bad and investigated a little further to make sure I ordered the right part. When I looked under there, the bracket was no longer attached, and the sensor wires were resting on the turbo and burnt. Apparently they had to remove it to change the belt & tensioner? In any case...Anyone know the bolt size for that bracket so I can re-attach it when my new sensor gets here?

 

I'm having a hard time figuring out which bolt and bracket you are referring to? Looks to me like the O2 sensor cable just clips onto the cam cover and dip stick bracket:

 

There's a bracket under there that the end of the plug slides onto that's bolted to the block.
