Recurring engine bank 1 sensor 1 trouble code
about 2 months ago i posted a thread where i learned how to scan the engine for DTCs. the CEL had come on and i scanned to find the 2005 chevy 6.0L (the chevy has 43,000 mi) had two codes: P0449 (EVAP...

new sensor is in. i erased codes, so we'll see...j-d said what i have gleaned from many websites "Bear in mind, it's "probably" the O2 sensor. Commonly replaced, consumable kind of part. Same idea as a spark plug. Still, other problems in a system "can" trigger a code so simply replacing the part bearing the code's name may not clear the problem."
When we went to autozone, they only had Bosch. so for a 1st timer, i figured i'd just try it for $47. i also had realized i had no 7/8" wrench, and they were out of slit sockets, so i got what was there, a $10 12" long 7/8" wrench (open/box ends). turns out this was fortunate as the old sensor was frozen on even w/ WD40.
the slit socket would not have worked - no room, so i agree w/ you guys that the offset O2 wrench is likely better. but FYI, the old and new end wire harnesses both pass through the box end of the 7/8" wrench. so with running the engine to heat the metals, more WD40, and that 12" leverage, i somehow got one lucky sharp rap that broke frozen O2 free to hand turn.
fingers crossed and thanking you all once again for leading this novice wrench thru yet another fix-it adventure.
