CEL code 45
just wanted to get this in here in case it can benefit anyone.
My truck reported a check engine light with a cde 45 (right lamda / O2 sensor) fault.
the fault was not the O2 sensor but rahthr the hose to the MAF being loose. tightened them up (intake and MAF) and it runs great again.
Low idle (200-250rpm)
YMMV - contents may settle...
Defenders don't wear out they just need more parts.
