Hi EmFer's,

This vehicle came in for a routine smog inspection. It passed visual, functional and tailpipe. I'm just curious as to why there isn't a cat monitor on this vehicle. Anyone know?

The label says Medium Duty, but the GVWR on the door says 6650. The PCM monitoring the 4 oxygen sensors before and after the left and right front cats.
